    Berättande i digitala spel: En undersökning av monomyten och dess gestaltning2012Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Den här uppsatsen undersöker monomytens två inledande steg The Ordinary World och The Call to Adventure samt hur dessa kan gestaltas i digitala spel. Syftet är att få insikt i hur spelmediet kan använda sig av de här teorierna om berättelsestrukturer för att skapa mer engagerande upplevelser. För att undersöka problemområdet konkretiserades teorierna i ett ramverk utifrån vilket en spelprototyp utvecklades och två redan existerande digitala spel analyserades. Prototypen jämfördes med de analyserade spelen för att undersöka på vilket sätt teorierna om The Ordinary World och The Call to Adventure gestaltats. Undersökningen visade på att spelmediet erbjuder en mängd olika sätt att gestalta teorierna på och vilka för- och nackdelar dessa gestaltningssätt har. Vidare pekade användandet av monomyten på dess fortsatta relevans inom spelmediet, men även på de problem som reproduktionen av monomytens struktur kan leda till.

    Underlivskollen: Ett designförslag på ett läromedel för att öka kunskaperna kring det kvinnliga underlivet2018Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [en]

    In today’s society there are problems with how women look at themselves and their appearance, not least the appearance of their genitals. There are norms that say that genitals should look in a certain way. To prevent these problems, young persons need to learn in school how much variation there may be on the appearance of the genitalia. Therefore, this study aimed to create a design proposal on a digital teaching material which was based on the questions that young boys and girls have about the appearance of women’s genitals, and also what information today’s educational books contain. The result showed that girls have questions regarding, among other things, labia, pubic hairs and operations. The educational books which was analysed contained information restrained to a picture of the female genitalia, or a few sentences. The design proposal presented was a website where the user can see different looks on the female genitalia, read and answer questions that young girls have, as well as discuss issues with classmates.

    Most Valuable Player?: Assessing the impact of individual team role activity on team performance in a microworld environment2017Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [en]

    Studying team performance dynamics in tasks and activities has proven difficult because of the dynamic and unpredictable nature of the real world. Microworld systems aim to address that issue by providing researchers with controllable simulated environments that captures the essence of their real-world counterpart activities. This study utilized one such microworld system, called C3Fire, to simulate a forest firefighting setting where 48 participants divided into 12 teams were tasked with cooperating in extinguishing the fires. Teams consisted of four roles – each with its different responsibilities and resources. The aim of this study was to determine whether any individual team role had a greater impact on team performance than the other roles. Each team encountered three distinct scenarios of varying difficulty. Command input action counts and self-assessed performance scores were collected for each participant. These measurements were tested for correlations with team scores. The logistics chief role, who was responsible for re-filling and re-fueling other units, stood out as being the only role whose command input count correlated with team score, and being one of only two roles for which command inputs and self-assessed performance scores were correlated, as well. Results of a multiple regression procedure also indicated that the command counts of the logistics chief was a significant predictor of team score.

    Utvärdering av mobila gränssnitt för användare med nedsatt syn: Evaluation of mobile interfaces for visually impaired users2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this study came about during ongoing discussions with a newly started company that plans to launch an application focused on fitness and health. The application must be accessible to a broad user group, this include users with some kind of disability. A large percentage of the population and a potentially large percentage of the company ́s prospective users have some kind of disability that can complicate use of the service, impaired vision is the most common kind of disability today. This study is based on the need to develop a concise and effective evaluation model intended to evaluate usability and to detect any possible problems that exist for users with visual impairments when using mobile services. Qualitative data has been collected from user testing and subsequent interviews. All test participants have a mild alternatively moderate visual impairment, the usability expert who carried out the heuristic evaluation is not visually impaired. The presented usability model has been tested and analyzed by posing as the basis for the heuristic evaluation, results found in this stage are then compared with results obtained from user testing in order to determine whether satisfactory results are met. The model shows satisfactory results based on obtained data, problems detected during the heuristic evaluation corresponds in a consistent manner with problems that emerged during user testing. The study indicates that there is a lack of specific and easy to use usability models for the evaluation of mobile services with a focus on visually impaired users. Such a model can preferably be used in order to increase usability and provide a more accessible service. Existing usability frameworks are often extensive and targeted at a broad user group. They can be supplemented with a time and cost efficient usability model directed at evaluating accessibility for a specific user group. The presented model is based on the principles of Universal Design which will hopefully contribute to a greater usability for the general user as well. In addition to improved usability a potentially great economic profit can be made by developing a more accessible service that can be used by more users. The study is based on proven methods and has support in existing theory which contributes to a higher quality assurance, however, the narrow scope of the study contributes to the necessity of further testing.

    To start this vehicle, please verify yourself: Security and privacy, where shall we draw the line?2005Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    Different security issues are a top subject around the world, especially since the terror threats seem to intensify. In the same time, the transport industry suffer from problems with smuggling and theft of valuable goods. One way to increase the security might be to have a verification system installed in commercial trucks, in order to assure that the driver is the proper one.

    This thesis has two purposes. One is to find appropriate methods for driver verification and build a prototype of a verification system which can be used for testing and further development. The other is to study how truck drivers perceive such a system and how their conception goes along with the growing demand for higher security. The present work is the result of a cooperation between an engineer and a cognitive scientist. The thesis focuses on the transport industry and was performed for Volvo Technology Corporation (VTEC), Gothenburg, Sweden.

    Eleven available verification methods were studied. To enable a well-based selection of methods to implement in the prototype, inquiries and interviews with truck drivers and haulage contractors were carried out to complement the theoretical study.

    One regular and three biometric verification methods were chosen for the test; fingerprint verification, face recognition, voice recognition and PIN verification. These methods were put together to a prototype system that was implemented in a truck simulator. A graphical user interface was developed in order to make the system user friendly. The prototype system was tested by 18 truck drivers. They were thoroughly interviewed before and after the test in order to retrieve their background, expectations and opinions as well as their perceptions and experiences of the test.

    Most of the test participants were positive to the prototype system. Even though they did not feel a need for it today they believed it to “be the future”. However, some participants felt uncomfortable with the system since they felt controlled by it. It became clear how important it is to have a system that respect the users’ privacy and to assure that the users are well informed about how the system is used. Some of the technology used for the verification system requires more development to fit in the automotive context, but it is considered to be possible to achieve a secure and robust system.

    Language and teaching ethics2018Conference paper (Refereed)
    Abstract [en]

    All problems with learning are increased when using English to teach non-English native students because of the culturally-sensitive nature of the subject of ethics. Coming to teaching ethics we are confronted with more difficulties. What is right and wrong is often affected by the culture, and different cultures often have different languages. Ethics theories are also expressed in language terms and they can be more easily misunderstood or misinterpreted compared to natural science theories. The feelings and every-day life encounters with “right” and “wrong” are linguistically experienced, described, and mediated. Therefore, language has a strong impact on whether something is ethical or whether it makes sense as an ethical issue at all.

    Robots, ethics and language2015In: Computers & Society: The Newsletter of the ACM Special Interest Group on Computers and Society Special Issue on 20 Years of ETHICOMP / [ed] Mark Coeckelbergh, Bernd Stahl, and Catherine Flick; Vaibhav Garg and Dee Weikle, ACM Digital Library, 2015, p. 268-273Conference paper (Refereed)
    Abstract [en]

    Following the classical philosophical definition of ethics and the psychological research on problem solving and decision making, the issue of ethics becomes concrete and opens up the way for the creation of IT systems that can support handling of moral problems. Also in a sense that is similar to the way humans handle their moral problems. The processes of communicating information and receiving instructions are linguistic by nature. Moreover, autonomous and heteronomous ethical thinking is expressed by way of language use. Indeed, the way we think ethically is not only linguistically mediated but linguistically construed – whether we think for example in terms of conviction and certainty (meaning heteronomy) or in terms of questioning and inquiry (meaning autonomy). A thorough analysis of the language that is used in these processes is therefore of vital importance for the development of the above mentioned tools and methods. Given that we have a clear definition based on philosophical theories and on research on human decision-making and linguistics, we can create and apply systems that can handle ethical issues. Such systems will help us to design robots and to prescribe their actions, to communicate and cooperate with them, to control the moral aspects of robots’ actions in real life applications, and to create embedded systems that allow continuous learning and adaptation.

    Jag ser inte vad du säger: En studie av dövas subjektiva upplevelse av kvaliteten på kommunikation via 3G-telefoner2006Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Teckenspråket är ett visuellt språk, med möjligheter att uttrycka mycket information simultant. Faktorer som har en avgörande betydelse för språket är handens form, placering och rörelse, i kombination med ögon- och munrörelser. Utvecklingen av videosamtal via 3G har inneburit att döva kan konversera mobilt på sitt modersmål. Tidigare har de i många situationer varit hänvisade till sitt andraspråk, svenska. Denna uppsats undersöker hur döva upplever kvaliteten på kommunikation via videosamtal, samt huruvida de för teckenspråket viktiga faktorerna får tillräckligt med utrymme i dagens 3G-telefoner. Studien är av kvalitativ art och metoden som använts är framför allt intervju. Resultaten visar att kvaliteten upplevs som sämre än vid kommunikation öga mot öga, bland annat till följd av att vissa teckenspråkliga element inte kan kommuniceras med dagens teknik. Språket anpassas på så vis att enklare tecken används, de utförs långsammare och upprepas oftare. Av studien framgår att det finns ett behov av vidare forskning inom området, för att mobil teckenspråkig kommunikation ska fungera på ett för döva tillfredsställande sätt.

    Knock on Wood: Does Material Choice Change the Social Perception of Robots?2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    This paper aims to understand whether there is a difference in how socially interactive robots are perceived based on the material they are constructed out of. Two studies to that end were performed; a pilot in a live setting and a main one online. Participants were asked to rate three versions of the same robot design, one built out of wood, one out of plastic, and one covered in fur. This was then used in two studies to ascertain the participants perception of competence, warmth, and discomfort and the differences between the three materials. Statistically significant differences were found between the materials regarding the perception of warmth and discomfort

    Conversational Effects of Gender and Children's Moral Reasoning2007Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    This thesis aimed partly to examine the effects of gender on conversation dynamics, partly to investigate whether interaction between participants with contrasting opinions promotes cognitive development on a moral task. Another objective was to explore whether particular conversational features of interaction would have any impact upon a pair’s joint response or on each child’s moral development. The conversations were coded with regard to simultaneous speech acts, psychosocial behaviour and types of justifications used. The results show no gender differences regarding psychosocial processes, but the boys used more negative interruptions, more overlaps and significantly proportionately more justifications in the form of assertions than the girls in the study. Gender differences were often more pronounced in same-gender as opposed to mixed-gender pairs, but children also altered their behaviour to accommodate to the gender of their conversational partner. Children who participated in the interaction phase of the study showed more overall progress on an eight-weeks delayed post-test than those who did not. However the only conversational feature that was related to the outcomes of conversation and development was the use of expiatory force justifications which were associated with a more advanced reply immediately after interaction as well as two weeks later.

    Employing the secondary task technique for measuring MRP pilots' cognitive load2018In: Proceedings of the 10th Nordic Conference on Human-Computer Interaction, ACM Press, 2018, p. 706-710Conference paper (Refereed)
    Abstract [en]

    Mobile Remote Presence (MRP) technologies make it possible for the user to be mobile in a remote environment, which opens up new possibilities for interaction. However, this new functionality comes at a cost. The need for MRP system users to pay attention to both telecommunication and device navigation increases their cognitive load. Assessing the cognitive load of MRP system users is a timely research issue, which is addressed in this paper both conceptually and empirically. We argue that Secondary Task (ST) techniques have certain advantages over existing Subjective Rating Scales (SRS) instruments, and report a study, in which a particular ST technique, a visual monitoring task, was employed to assess MRP pilot’s cognitive load. The empirical evidence from the study indicates that the method provides additional valuable insights into MRP pilots’ user experience.

    Universe-defining rules2014Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Abstrakt I detta arbete undersöks hur konceptet lek går att applicera på digitala spel och hur man presenterar ett fiktivt universum och de regler som definierar det universumet. Syftet med denna undersökning är att öka kvaliteten på digitala spel för spelare genom att öka förståelsen för hur sådana regler introduceras. Frågeställningen som ämnas att besvaras är “hur kan man introducera realistiska, semi-realistiska och fiktiva regler i ett spel?”. Undersökningen baseras delvis på analyser kring varför vissa introduktioner av regler ofta accepteras och andra inte, dels på utvärdering av en gestaltning och dels på tidigare forskning. Denna undersökning är indelad i två delar; en researchdel och en produktionsdel. För att besvara frågan har research skett kring vad som känns till sedan tidigare och ett digitalt spel har producerats där den stora regeln som skiljer verkligheten från detta fiktiva universum är paranormal aktivitet, eller spöken. Nyckelord: regler, magisk cirkel, inlevelse och spelproduktion. Abstract In this work the concept of play and how it may be applied to digital games and how to introduce a fictional universe and the rules that define that universe is being investigated. The purpose of this work is to increase the quality of digital games by increasing our understanding of how such rules may be introduced. The question to be answered is “how may realistic, semi-realistic and fictional rules be introduced in a digital game?”. This work is based partly on analyses on why some introductions of rules are often accepted and some often not, partly on evaluation of a product created by us and partly on earlier research. This work is split into two parts; one research part and one production part. To answer the question research about what is previously known has been conducted and a digital game has been produced where the main rule that separates the fictional universe from ours is paranormal activity, or ghosts. Keywords: Rules, magical circle, immersion and game production.

    Cognitive Learning, Monitoring and Assistance of Industrial Workflows Using Egocentric Sensor Networks2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 6, article id e0127769Article in journal (Refereed)
    Abstract [en]

    Today, the workflows that are involved in industrial assembly and production activities are becoming increasingly complex. To efficiently and safely perform these workflows is demanding on the workers, in particular when it comes to infrequent or repetitive tasks. This burden on the workers can be eased by introducing smart assistance systems. This article presents a scalable concept and an integrated system demonstrator designed for this purpose. The basic idea is to learn workflows from observing multiple expert operators and then transfer the learnt workflow models to novice users. Being entirely learning-based, the proposed system can be applied to various tasks and domains. The above idea has been realized in a prototype, which combines components pushing the state of the art of hardware and software designed with interoperability in mind. The emphasis of this article is on the algorithms developed for the prototype: 1) fusion of inertial and visual sensor information from an on-body sensor network (BSN) to robustly track the user’s pose in magnetically polluted environments; 2) learning-based computer vision algorithms to map the workspace, localize the sensor with respect to the workspace and capture objects, even as they are carried; 3) domain-independent and robust workflow recovery and monitoring algorithms based on spatiotemporal pairwise relations deduced from object and user movement with respect to the scene; and 4) context-sensitive augmented reality (AR) user feedback using a head-mounted display (HMD). A distinguishing key feature of the developed algorithms is that they all operate solely on data from the on-body sensor network and that no external instrumentation is needed. The feasibility of the chosen approach for the complete action-perception-feedback loop is demonstrated on three increasingly complex datasets representing manual industrial tasks. These limited size datasets indicate and highlight the potential of the chosen technology as a combined entity as well as point out limitations of the system.

    Utformning av ett nationellt kunskapsstöd för primärvården i Sverige: Ett kunskapsstöd för att möjliggöra mer jämlik vård2016Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [sv]

    Kunskapsbaserade stöd får en allt mer central roll inom vård och omsorg. De viktigaste rekommendationerna som idag finns är de nationella riktlinjerna som Socialstyrelsen har tagit fram. Som det ser ut idag används dessa i olika utsträckning inom primärvården runt om i Sverige och många landsting har sina egna varianter på kunskapsstöd. Därför ska ett nationellt kunskapsstöd utvecklas som alla kan ta del av för möjliggörande av att patienten får den bästa möjliga vården, vilket också ska leda till en mer jämlik vård i hela Sverige.

    I denna studie samlades information in om hur ett sådant stöd skulle kunna utformas via 8 intervjuer med läkare där resultatet sedan användes för att utforma en enkät som 16 personer inom primärvården från olika landsting besvarade. Enkäten behandlade frågor om hur de ville att informationen skulle presenteras och vilka huvudrubriker de ansåg vara viktigast i ett kunskapsstöd.

    Det visade sig att Behandling var den viktigaste huvudrubriken, att lättanvänt och pålitligt är viktiga egenskaper hos ett kunskapsstöd och att informationen ska presenteras kortfattat så att läkaren snabbt kan få en överblick av informationen då läkare ofta har tidsbrist.

    CORTICAL PHASE SYNCHRONISATION MEDIATES NATURAL FACE-SPEECH PERCEPTION2015Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    It is a challenging task for researchers to determine how the brain solves multisensory perception, and the neural mechanisms involved remain subject to theoretical conjecture.  According to a hypothesised cortical model for natural audiovisual stimulation, phase synchronised communications between participating brain regions play a mechanistic role in natural audiovisual perception.  The purpose of this study was to test the hypothesis by investigating oscillatory dynamics from ongoing EEG recordings whilst participants passively viewed ecologically realistic face-speech interactions in film.  Lagged-phase synchronisation measures were computed for conditions of eye-closed rest (REST), speech-only (auditory-only, A), face-only (visual-only, V) and face-speech (audio-visual, AV) stimulation. Statistical contrasts examined AV > REST, AV > A, AV > V and AV-REST > sum(A,V)-REST effects.  Results indicated that cross-communications between the frontal lobes, intraparietal associative areas and primary auditory and occipital cortices are specifically enhanced during natural face-speech perception and that phase synchronisation mediates the functional exchange of information associated with face-speech processing between both sensory and associative regions in both hemispheres.  Furthermore, phase synchronisation between cortical regions was modulated in parallel within multiple frequency bands.

    Evoked Multisensory Cortical Representations During Unisensory Stimulation2013Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [en]

    The primary aim of this study was to establish whether redintegrative effects can be revealed under conditions with complex sensory stimulation.  Specifically, would the cortical activity involved in the single-trial, passive encoding of a movie, be reactivated when subsequently exposed to a unisensory component of that movie, e.g. an audio- or visual-only segment?  High-density electrical neuroimaging analysis in the frequency domain was used to assist this aim.  The statistical comparisons revealed a greater number of oscillating neuronal regions across all frequency bands in participants who received audiovisual stimulation prior to unisensory exposure (compared to participants who experienced the same unisensory stimulus without prior audiovisual stimulation).   This difference between groups was significant in the alpha2 (right frontal lobe) and gamma (right frontal, sub-lobar and temporal lobes) frequencies during audio-only stimulation.    This enhanced cortical activity during unisensory stimulation suggests that participants were retrieving associated memory traces from their prior multisensory experience, although specific redintegrative effects could not be confirmed.

    SOUNDSTAGE: Miljöförstärkt ljud i smartphone2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det här arbetet syftar till att genom design av en telefonapplikation undersöka hur ljud kan förstärkas av den omgivande miljön. Arbetet visar på hur miljöförstärkt ljud skiljer sig från ljudförstärkt miljö samt vilka begränsningar det innebär att använda en vanlig smartphone som plattform. 

    Ett långsiktigt mål är att genom en produkt som låter oetablerade ljudproducenter distribuera sina alster i den offentliga miljön främja fri kultur och kreativitet.

    Arbetet har följt principen för RtD (research through design), där designprocessen utgör det fall som studeras och dokumentationen av den utgör den bas av data som analyseras och leder till slutsatser kring ämnet.

    Designprocessen i detta arbete innebär en mindre omfattande användarstudie i enkätform för att identifiera målgrupp, krav och mål. Följd av en andra studie där en prototyp framtagen med grund i resultaten från användarstudien utvärderas av deltagare genom observation, intervju och reaktionskort. 

    De största utmaningarna för designen grundar sig i att ta fram en applikation som inte stör upplevelsen, men samtidigt kan instruera användaren i hur man använder applikationen. Utifrån arbetet dras slutsatsen att användarinstruktioner, såväl visuella som auditiva, löper större risk att störa upplevelsen i miljöförstärkt ljud än i ljudförstärkt miljö. Vidare konstateras att den största bristen i en lösning som bygger på standardutrustning i jämförelse med en lösning som nyttjar dedikerad utrustning utgörs av begränsningar när det kommer till att ange riktning med hjälp av ljudets rumslighet.

    Ways of Seeing Service: Surrogates for a Design Material2015In: NorDes 2015: Design Ecologies, 2015, Vol. 6, p. 1-4Conference paper (Refereed)
    Abstract [en]

    Current trends in service design research include case studies and similar approaches that aspire to reveal what the practice of service design looks like. The understanding of how service design is performed can serve as a base for future research into more specific research endeavours. One area where knowledge is said to be lacking is service prototyping, part of which knowledge this paper attempts to contribute. The main data source for the paper is findings from in-depth interviews with six practicing service designers from some of the more well-known design agencies. The informants consider service prototyping to be a very important part of their work that allows them to learn and communicate about design ideas. The practitioners’ account of how they work with prototypes indicates that service prototyping has different meanings and that the practice of prototyping is very diverse. The interviews also uncover a number of areas that, according to the designers, might prove extra challenging for service prototyping to be successful. This research shows that there is much potential in the not yet fully formed practice of service prototyping.

    Pausing or not?: Examining the Service Walkthrough Technique2014In: Proceedings of the 28th International BCS Human Computer Interaction Conference on HCI 2014: Sand, Sea & Sky - Holiday HCI / [ed] Daniel Fitton, Matt Horton, Janet C Read, Gavin Sim, London, UK: British Computer Society (BCS), 2014, p. 171-176Conference paper (Other academic)
    Abstract [en]

    The scope of service design calls for holistic design techniques that represent multiple service moments. One such technique is the service walkthrough that can be used to prototype and formatively evaluate services. A service walkthrough is an enactment of several consecutive service moments. This paper informs decisions about how to set up service walkthroughs by looking at two kinds of walkthroughs in a case study: with pauses for discussion and feedback after each service moment, and without pauses where the entire service journey is walked through before comments and feedback are collected. The case study did not show any differences in the content of the feedback, but more feedback was given in the walkthroughs with pauses. The feedback in the paused walkthroughs was also more detailed.

    Using Service Walkthroughs to Co-Create Whole Service Experiences2012In: ISIDC 2012, 2012, Vol. 3Conference paper (Other academic)
    Abstract [en]

    A process for prototyping whole services rather than individual parts in isolation is needed. Prototyping services is different from prototyping physical products, yet many designers still use traditional approaches to prototype services, focussing on specific parts rather than whole services. This is especially surprising considering the descriptions of service design as a holistic approach in research. In this paper we suggest and describe a service prototyping technique termed service walkthrough. The service walkthrough technique allows access to service experiences from a holistic point of view, representing not only specific parts (service moments or touchpoints) but also transitions and coherence of the service proposition. In this case, 25 walkthroughs were conducted by a service design agency in Australia. The approach was iterative in the sense that the customer journey was redesigned continuously, and it was enacted by designers supported by scripts for behaviours based on a previous research phase. The walkthroughs were conducted in a lab with actual customers of the client and used low-fidelity props and collateral. Errors were introduced during the walkthrough to gain a better understanding of what expectations the customers have on the service. The walkthrough technique allowed the designers to understand the service experience in an embodied and holistic way. The walkthrough also emphasised empathy for the experience of the intended customers and other stakeholders in the service. More time in between iterations and dynamic roles might improve the approach.

    Existing Prototyping Perspectives: Considerations for Service Design2011In: Proceedings of the Nordes’11: The 4th Nordic Design Research Conference, Making Design Matter, 29-31 May Helsinki, Finland, Helsinki, Finland: School of Art & Design, Aalto University , 2011, p. 31-40Conference paper (Refereed)
    Abstract [en]

    With new design disciplines that challenge the borders of design practice and inquiry comes new possibilities for prototyping techniques and approaches. The basis for such an evolution is a firm understanding of the existing knowledge generated in design and the challenges posed by new design disciplines, such as service design. This study identifies a framework of perspectives for prototyping to reveal what the existing toolbox of prototyping contains based on a literature overview. Going through published literature from the early 1980s and onward, the framework is constructed using the following perspectives; purpose, fidelity, audience, position in the process, technique, and representation. These perspectives make knowledge about prototyping explicit and summarise contemporary approaches. Based on current challenges and characteristic attributes of service design the framework is then reconstructed to better cater to design for services. The conclusions are that validity and author are two perspectives that complement the existing framework, and that prototyping so far does not support a holistic approach to prototyping services.

    Prototype Evaluation in Service Design: A Case Study at an Emergency Ward2011In: Proceedings of 20th IASDR 2011, International Association of Societies of Design Research (IASDR) , 2011Conference paper (Other academic)
    Abstract [en]

    Prototypes based on user research are embodiments of hypotheses about how behaviour and experiences will change. The purpose of prototypes has been discussed in academic literature but in the case of service design, some of that knowledge needs to be re-examined. In Service design, one of the problems is that the impact of prototypes is complex and difficult to predict. A way to counter this dilemma is to put more focus on making the hypotheses explicit and testable. This paper presents a practical process for using designers’ hypotheses to generate survey tools for evaluating the impact of prototypes in service systems. This is also a way for designers to verbalize the purpose of service prototypes in a contextual and situated way. The tool was designed to be quick, easy, and light-weight, to suit the needs of design consultants, and it focused on measuring the experiences of a waiting room from the perspective of the visitors. The process has been applied to a project where the waiting room of an emergency ward was redesigned. The three-step process started with building up the hypothesis structure, where the designers’ assumptions and intentions were used to make a representation of the hypothesis. The next step was formulating questions, where questions that tested the hypothesis were formulated. The last step – making the questionnaire – included the selection of what information to gather and iterative testing of the questions. It was found that the designers did not have a well-defined hypothesis. The suggested process can help designers identify a contextual and situated purpose for prototypes.

    Service Designers on Including Stakeholders in Service Prototyping2011In: INCLUDE 11 Proceedings “The Role of Inclusive Design in Making Social Innovation Happen, 2011Conference paper (Other academic)
    Abstract [en]

    Services are by nature co-created. They are produced and consumed simultaneously through interactions between customers and service providers. The professional design of services is also highly associated with co-creation, which is evident in the sparse service design literature. This paper reveals what designers say they do to involve different stakeholders in the process of prototyping services. The main data source is interviews with designers from design agencies that work exclusively or partially with service design. The paper focuses on the questions of "who is involved in creating prototypes", "who evaluates the prototype" and how "the clients [of the design agencies] are involved". A distinction is made between different types of involvement based on previous literature that characterise different roles and perspectives on inclusion in design. Results show that most of the agencies involve others besides the design team in the creation and evaluation of prototypes. The primary stakeholder in co-creation is the client. End customers are involved also but for the most part, both clients and customers have the role of subjects or informants rather than partners in the creation of prototypes. The evaluation of prototypes follows the same pattern, and a key aspect to some of the agencies is that the client is involved, as a domain expert. The question of who authors prototypes, and implications thereof, is raised and further discussed.

    Communication through Boundary Objects in Distributed Agile Teams2015Conference paper (Refereed)
    Abstract [en]

    Personal communication between User-Centered Design (UCD) specialists and developers is important for communicating user needs and design solutions in agile development. In distributed projects where opportunities for personal communication are limited, the design documentation is an important surrogate. This study has investigated the perceived effectiveness of boundary objects in a distributed agile team, and their role in communicating target user needs. Six in-depth interviews with UCD specialists showed that the boundary objects rarely communicate underlying needs of the users but rather focus on interaction with the system that is being developed. The used boundary objects also do not work as stand-alone deliverables; they need to be explained and elaborated. Making the boundary objects comprehensive enough to be stand-alone is seen as too time consuming and not worth the effort. For agile projects with distributed teams, this creates hand-over and follow-up problems.

    Investigating Prototyping Practices of Service Designers from a Service Logic Perspective2011Conference paper (Other academic)
    Abstract [en]

    The view of the nature of services has changed with the introduction of the service dominant logic. An important part of the logic is that services create value-in-use for customers. Customer-focused disciplines such as many design disciplines have a history of working with prototyping to understand the value-in-use. The service design discipline has a similar approach to the development of services. Based on previous research a framework of perspectives on service prototyping is presented which can be used to understand the prototyping approach utilised by designers. Then, using four of the suggested foundational premises of the service dominant logic this paper examines some of the ways prototyping can support the understanding and development of value propositions. The analysis shows that prototypes and the development and testing of them with customers and users can be seen as a tool for making sure that the value propositions offered by the companies are right, as well as exploring the customer’s role as a co-creator of value. The prototyping framework can be used to practically manifest the service-dominant logic in the development of service prototypes.

    User-centred design and agile development of IT systems2006Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Despite the knowledge on the interaction between humans and computers, too many IT systems show great deficits when it comes to usability. Every day we run into technology that makes our every day life and our work unnecessarily complex and difficult because of the IT systems that are not designed to support our tasks in a usable way. This thesis deals with different aspects of usability and the process of how to develop usable IT systems effectively. Primarily, the systems concerned are used in professional work, such as case handling systems in large government organisations.

    The main objective of this research is to understand which essential factors in the system development process that facilitate the development of usable IT systems. Another key subject is how human-computer interaction (HCI) knowledge can be integrated into systems development, in particular the integration of user-centred design (UCD) and agile software development. The research is based on a qualitative approach and on reflections from my own experience in development projects. It also includes exploratory studies and design cases.

    The attempts of bridging the gap between HCI and software engineering have not been notably successful in practice. To address some of these problems, there is a need for a more precise definition of user-centred design, which is proposed in the thesis. Also, the complicated reality of systems development is not considered enough by HCI researchers and practitioner. To reach better results, UCD has to be integrated as a natural part of the development process. In the thesis, I argue that the agile approach together with UCD can be a good starting point for this integration. The agile approach emphasises that responding to change in development is more important than strictly adhering to a plan. Also, it prioritises regular deliveries of working software over extensive models and documentation. However, from an HCI perspective, agile processes do not inherently provide the required support for user-centred design. Nevertheless, the basic values and specific methods of agile development may have the potential to work very well together with UCD. For instance, iterative development is fundamental to both user-centred design and agile development.

    Finally, the research addresses how iterative methods can be used to find design solutions that support the users to cope with the problems of overview and control in case handling work.

    Personas in Action: Ethnography in an Interaction Design Team2002In: The Second Nordic Conference on Human-Computer Interaction / [ed] Bertelsen, Olav W, New York: ACM , 2002, p. 197-200Conference paper (Refereed)
    Abstract [en]

    Alan Cooper's view on interaction design is both appealing and provoking since it avoids problems of involving users by simply excluding them. The users are instead represented by an archetype of a user, called persona. This paper reports a twelve-week participant observation in an interaction design team with the purpose of learning what really goes on in a design team when they implement personas in their process. On the surface it seemed like they used personas, but our analysis show how they had difficulties in using them and encountered problems when trying to imagine the user. We furthermore describe and discuss how the design team tried to involve users in order to compensate for their problems. It is concluded that it is not enough for the design team, and particularly not for the interaction designers, to have the know-how of using the method. They also have to integrate it with existing knowledge and practices in order to feel at home with it and use it efficiently.

    Online Engagement in the Eye of the Young Beholder: A study on what youth appreciate on mobile-friendly websites2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Today's youth use their mobile phones in the same way as earlier generations used their computers. Therefore, web designers need to make websites mobile-friendly when aiming for the younger generation’s attention. In collaboration with Ashoka and Raoul Wallenberg Academy, within a project named Changemakers’ Yard, this thesis investigates what factors in terms of content and design youth in the age of 16-23 appreciate on a mobile application or website. The outcome of the thesis aims to guide web designers on what to keep in mind when designing mobile applications or websites for today’s youth. A quantitative and qualitative research was done by performing interviews, an online survey and two customized lectures with the target group. Data and comments from the research were then analyzed and summarized to form a paper prototype which was developed into a digital prototype. Both prototypes were evaluated via user tests with the target group. Finally, ten guidelines were compiled on what youth appreciate when it comes to the content and design on mobile-friendly websites. The guidelines focused on communication and usability, as well as site owners taking responsibility for updates and minimize the amount of data used. The responsibility of keeping the website updated as well as minimizing the amount of data, were both new findings. In addition, arguing against prior research, there were indications of differences between the genders regarding preferred content.

    Perception of Trustworthiness and Valence of Emotional Expressions in Virtual Characters2016Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Knowledge on how to design trustworthy virtual characters are of importance when these are becoming more and more common interaction partners. In this study, a closer look at the suggested relationship from previous research between valence and trustworthiness is investigated by constructing virtual characters with different non-verbal behaviours and letting participants rate them in a pre-study. A second question of how perception of trustworthiness is based for virtual characters is investigated by letting participants play a trust game with life-sized virtual characters on a big 4k-screen. Results indicated that valence is not necessarily a factor influencing trustworthiness and that positive valence together with mutual gaze is not enough to provide a clearly trustworthy virtual character. Results also indicated that perception of trustworthiness is not based solely on a virtual character's previous decisions of trust in a longer interaction but also on its non-verbal behaviour. The outcome of this study will help when constructing virtual characters in different scenarios, especially when the goal is to make them as trustworthy as possible. The study also gives insight into tools and software that can be used when creating virtual characters and setting up scenarios of trust.

    Ett gränssnitt för anonymisering2017Independent thesis Basic level (degree of Bachelor), 12 credits / 18 HE creditsStudent thesis
    Abstract [sv]

    Arbetets museum samlar in personliga berättelser om arbetsliv, dessa berättelser innehåller ofta personlig information om informanten samt dennes kollegor, familj, med mera. Arbetets museum skulle vilja göra dessa berättelser tillgängliga via internet så att allmänheten och forskare skall kunna ta del av dem. För att göra detta måste den personliga informationen tas bort i en anonymiseringsprocess. Detta steg har visat sig vara väldigt tidskrävande. I ett samarbete med Swe-Clarin har Arbetets museum påbörjat arbete med att ta fram ett verktyg för att underlätta denna process. Genom intervjuer har en kravspecifikation om vad ett sådant verktyg behöver innehålla tagits fram. Designlösningar för specificerade krav har utvecklats och utvärderats. Utvärderingarna visade på bättre användarupplevelse i verktyget jämfört med tidigare metoder.

    Older adults co-creating meaningful individualized social activities online for healthy ageing2018In: Building continents of knowledge in oceans of data: The future of co-created eHealth / [ed] Adrien Ugon, Daniel Karlsson, Gunnar O. Klein, Anne Moen, IOS Press, 2018, Vol. 247, p. 775-779Chapter in book (Refereed)
    Abstract [en]

    Social isolation and loneliness among older people is a growing problem with negative effects on physical and mental health. In co-creation with older adults individualized social activities were designed where older adults through computer mediated communication were able to participate in social activities without leaving their homes. Four types of activities were designed; outdoor activity, music event, visiting a friend and leisure activity. A participatory action research design was applied, where end users together with scientists from two research fields developed, tested and evaluated online participation in the activities. Usability and safety of the systems were major concerns among older adults. The evaluation pointed out that level of simplicity, usability and audio-video quality determined the level of satisfaction with the human interaction during the activity, thereby affecting the meaningfulness of the activity. The research presented in this paper constitutes the first step in a long-term research process aiming at developing a digital coaching system that gives older adults personalized support for increasing participation in meaningful social activities.

    Anti-Solutionist Strategies: Seriously Silly Design Fiction2016In: Proceedings of the 2016 CHI Conference on Human Factors in Computing Systems (CHI '16), New York, USA: ACM Press, 2016Conference paper (Refereed)
    Abstract [en]

    Much of the academic and commercial work that seeks toinnovate around technology has been dismissed as“solutionist” because it solves problems that don’t exist orignores the complexity of personal, political andenvironmental issues. This paper traces the “solutionism”critique to its origins in city planning and highlights theoriginal concern with imaging and representation in thedesign process. It is increasingly cheap and easy to createcompelling and seductive images of concept designs, whichsell solutions and presume problems. We consider a rangeof strategies, which explicitly reject the search for“solutions”. These include design fiction and critical designbut also less well-known techniques, which aim forunuseless, questionable and silly designs. We present twoexamples of “magic machine” workshops whereparticipants are encouraged to reject realistic premises forpossible technological interventions and create absurdpropositions from lo-fi materials. We argue that suchpractices may help researchers resist the impulse towardssolutionism and suggest that attention to representationduring the ideation process is a key strategy for this.

    Cognitive work analysis in practice: Adaptation to project scope and industrial context2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The Cognitive Work Analysis (CWA) framework is widely used by researchers for the analysis of complex systems. It, however, lacks the same impact amongst industrial practitioners. This thesis investigates possible adaptations of the framework to project and industrial constraints, and the consequences associated with such adaptations. Long haul heavy vehicle transportation is the application domain for the work presented in the thesis. The CWA framework has been applied within the Methods for Designing Future Autonomous Systems (MODAS) project. Adaptations have been made to fit the framework within the project constraints and the industrial contexts. Interviews with stakeholders in an industrial organization regarding possible use of models from the CWA framework have been made. The CWA was scaled to available resources when applied within the MODAS project. From this we realized that prioritization of work activity can have consequences on the resulting systems ability to handle unforeseen events. Further, a focus on the current system probed a rapid out-dating of the analysis due to technical development. The conclusion is that even if advantages are lost during adaptation due to practical constraints, the CWA framework could add value to practitioners within industry if adapted to the industrial context.

    Work domain analysis of an intensive care unit: An Abstraction Hierarchy based on a bed-side approach2016In: Proc. Human Factors and Ergonomics Society Europe Chapter 2015 Annual Conference, 2016Conference paper (Refereed)
    Abstract [en]

    Work in intensive care units requires interaction with several medical devices and interpretation of dynamic information from several sources. The aim of the current study was to gain understanding of the work domain to support the development of a holistic information environment and further analyses of risky situations. A total of 18 hours of bed-side observations at an intensive care unit and interviews with three experienced intensive care unit nurses were conducted in order to receive input data for the modelling of the work domain. The domain was modelled in an abstraction hierarchy, as according to the first phase of the cognitive work analysis framework. The results show that the ultimate purpose of the work carried out in an intensive care unit is keeping patients alive while gaining time for treatment, but also to perform treatment and relieve symptoms. The purpose is represented at the top level of the model, and lower levels include functions as supporting the patients’ vital functions and avoiding secondary complications. With this work domain analysis as a basis, three different design challenges identified can be dealt with systematically.

    Supporting industrial uptake of cognitive work analysis2015In: Proc. Human Factors and Ergonomics Society 59th Annual Meeting, Thousand Oaks, CA: Sage Publications, 2015, p. 170-174Conference paper (Refereed)
    Abstract [en]

    As part of a broader industrial project, the first two stages of a Cognitive Work Analysis (CWA, Work Domain Analysis [WDA] and Control Task Analysis [ConTA]) were completed for Long Haul Commercial Road Transport. To support the potential uptake of CWA by different stakeholders within the industrial organization, parts of the ConTA Contextual Activity Template (CAT) were truncated. The goal of the current, exploratory study, was to identify which stakeholders within the industrial organization could benefit from using the WDA or CAT for either their Strategic (Research) or Product (Development) planning, and over what time horizon. We observed differences in the perceived usefulness of the WDA and the CAT between the different stakeholders. Innovative solutions to the issues raised should significantly enhance the industrial use of Cognitive Work Analysis.

    Effektivisering av administrativt användargränssnitt2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Företaget Lawson använder sig utav ett användargränssnitt baserat på Java Swing till sin plattformLawson Grid för Java-applikationer. Detta användargränssnitt kallas Lawson Grid ManagementPages, och har ett antal problem som har identifierats. Bland annat så upplevs gränssnittet som svårtatt navigera, och att det upplevs även av användare som att det innehåller för mycket information.Genom att diskutera problemen med användare av gränssnittet och kravställare på företaget, så harett antal lösningar tagits fram och implementerats. Lösningarna är även baserade på litteratur sombeskriver bra standarder för design av användargränssnitt.Det nya användargränssnittet presenterar ett antal förslag på lösningar till dom problem som GridManagement Pages har. Ett stort koncept är färgkodning, där färg visar vilket tillstånd systemetbefinner sig i. Grönt representerar att allting är bra, gult representerar en varning och röttrepresenterar ett fel. Färgkodningen syns på individuella applikationer och dess information, så attanvändaren lätt ska kunna identifiera att det finns ett problem och följa färgerna dit problemetkommer ifrån för att då åtgärda detta. För att ytterligare göra det lättare för användaren att få enöverblick av systemet och inte få för mycket information på en gång, så har informationen delatsupp i olika flikar användaren kan välja mellan som minskar hur mycket data som visas igränssnittet. I samma tema att minska den information som är synlig finns även olika lägen att väljamellan, med möjligheten att välja vilka kategorier av data som visas.För att göra det lättare för användaren att navigera gränssnittet har det nya gränssnittet ävenbokmärken. Detta gör att användaren snabbare kan ta sig till en sida som användaren har lagt tillsom bokmärke, istället för att behöva navigera genom hela gränssnittet för att ta sig dit.Ytterligare förbättringar som kan göras i framtiden inkluderar bland annat att kopplaanvändarpreferenser till en specifik användare eller roll, där olika roller kan ha vissa bokmärkengemensamt som leder till sidor som innehåller vanliga operationer som den rollen utför.Detta resultat ger förhoppningsvis beställaren underlag att inspirera delegering av resurser inomföretaget till att utöka det befintliga användargränssnittet, med och utöver dom koncept sompresenteras i det här arbetet.

    Expected later information access invites shorter reading time and possible comprehension loss2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    With the increased use of technology in society, there are concerns about how reading is affected by the constant access to an incessantly increasing amount of information. The present study examined how reading strategies and resulting memory and comprehension is affected by the belief that information to be remembered would continue to be available. In a within- participant experiment, twenty-seven participants were instructed to read six texts, and led to believe that they would have access to some of the texts while later answering comprehension questions. The results showed that participants spent significantly longer time reading texts they believed would not be accessible later, compared to those they believed they would have access to (p= .0007, d = 0.47). The participants did achieve slightly higher scores on the comprehension questions for the texts they believed they would not have access to, compared to the other condition, but the effect was not significant. The findings have implications for potential changes to reading strategies in response to increased use of technology as an external memory and information storage. I discuss how these strategies could have affected the raise of Fake News, inasmuch as increased information load from the Internet leads to a less meticulous reading style.

    Mäns och kvinnors possible selves om framtida arbetsliv2003Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Människors yrkesval och syn på framtida arbetsliv influeras av olika faktorer som i sin tur har formats av evolutionen eller den sociala omgivningen. Människans kognitiva förmågor är ett av elementen som påverkar yrkesvalsprocessen, men är också kanske en bidragande orsak till könssegregeringen på arbetsmarknaden. Hur människor ser sig själva i den framtida yrkesrollen kan också vara en anledning till varför det finns en könsskillnad på arbetsmarknaden. Markus and Nurius (1987) har myntat begreppet ”Possible self”, vilket de definierade som självbilden i framtida situationer. Syftet med det här examensarbetet var att undersöka om det skiljer mellan män och kvinnors possible selves när det gäller deras syn på framtida arbetsliv. Mätinstrumentet som användes i studien var The possible self statement test. Resultatet visade att männens och kvinnornas possible selves om arbetslivet var ganska lika, endast två av 24 jämförelser åskådliggjorde signifikanta värden. Det som visade på signifikans (p<,05) var kategori Position med skalan för hur mycket försöksdeltagaren anser sig kunna påverka att det angivna possible self ska inträffar samt kategori Utveckling och stimulans med skalan för negativa känslor gentemot det angivna possible self.

    Emotions at play: gaining emotional knowledge using a video game2014Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The use of video games for teaching children different subjects is commonly believed to be a good  approach. In  general  has  learning  theme  for  these  games  focused  on  traditionally subject, such as math or biology. Important as they can be for education, other softer aspects can also be considered important for the children and education. One such aspect is emotions and the role it has on a social level. However, it is not much research showing how to use emotions  in  a  learning  game. In  this  thesis, I  examine  how  children  perceive  and  use emotions as they play a game specially designed for teaching emotions. The game utilises emotions  in  a  new  design  that  let  the  player  interact  with  cartoon  animals  in  different scenarios. I report findings based on a sample of thirty-three (33) preschool children, and six (6) parents who took part in the study. Data was collected using a qualitative method in a two step procedure with observation of play and follow up interviews in the first step, followed by video recordings of play and demonstrations using cuddly pets in the second step. Using an ecological framework for analysis and theory from the field of emotional intelligence, I show that children playing this game can perceive emotions expressed in the game. I also show that it is possible to play this particular game without the need to involve emotions. Children do not learn emotions from playing the game. These results carries important implication for the design of learning games as it illuminates that learning can come from possible sources other than the gameplay.

    Exploring the intersection of design, reflection and sustainable food shopping practices: The case of the EcoPanel2016Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Food production has been shown to have considerable negative impacts on the environment. A means to reduce this is to choose organic products when shopping for food.

    Through the case of the EcoPanel, a web application prototype that visualises the organic proportion of the household’s food shopping, the thesis explores the intersection between design, reflection and sustainable food shopping practices.

    In order to contextualise the role of the EcoPanel, the text discusses the concept of food shopping practice, both from the perspective of social practice theory (SPT), and the more focused food choice perspective. The studies show that it is fundamental to understand the complexity of choosing food, and the habitual aspect of practice, in order to understand the role of reflection in food shopping practice, and consequently the role of a tool for reflective decision-making, like the EcoPanel.

    We have used a research through design approach to develop the EcoPanel prototype. In an iterative process we probed how the EcoPanel could be designed to be as relevant and accessible for the users as possible. Essential in the process were the iterative user feedback sessions. The way in which the users answered the questions from the sessions formed the guiding principles for the development of the design.

    A central question in the thesis is to explore in what ways the users’ access to their individual sustainable grocery data provided by the EcoPanel affects their food shopping practices. The studies include monitoring sixty-five users of the EcoPanel over five months, a survey regarding aspects of lifestyle and attitudes to food, and interviews with ten of the users.

    The long-term study shows an increased organic purchase level (17%) for the EcoPanel users in comparison to the reference group. We also see that when the users receive feedback on their organic food purchases through the EcoPanel, they can make more reflective decisions. This is shown to be highly relevant and creates meaning for the users in several different ways. From this result, in combination with the result of the long-term study, we can conclude that the EcoPanel contributes with support for more sustainable food practices.

    The last question in the thesis is to understand how SPT can be useful for design practice. SPT shows a view that goes beyond the traditional interaction perspective, and points to the importance of approaching complex issues, such as sustainability challenges, with an awareness that also includes social and cultural aspects of the context. As well as this view being pertinent when approaching sustainability issues, it also provides value to designers in their emerging roles of dealing with more socially embedded concerns, such as social innovation and design for public policies.

    The EcoPanel: Designing for reflection on greener grocery shopping practices2015In: PROCEEDINGS OF ENVIROINFO AND ICT FOR SUSTAINABILITY 2015, Atlantis Press , 2015, p. 221-228Conference paper (Refereed)
    Abstract [en]

    While the purchases of organic food are increasing rapidly, it accounts for only a small fraction of the total consumption, and there is still a big gap between consumer values awareness and the actual consumption. This article explores how detailed personal feedback could help the households to gain insight and reflect on their consumption, the text presents the design process of developing a prototype, the EcoPanel, in collaboration with a major player on the food retail market. Based on the access to detailed tracking of purchase data, the aim of the design was to provide relevant feedback to facilitate for reflection on the user's own food choices. The design prototype is intended to serve as an instrument for insight and reflection and to bring unconscious aspects of grocery shopping to conscious awareness. Following a research through design approach, this article describes the interdependent steps in designing the EcoPanel and design decisions playing a role for users' critical reflection of their food choice practices. It discusses the intention of each module in providing insight. Finally, we discuss how a social practice perspective may be useful for identifying fruitful future research into the design for more sustainable grocery shopping practices

    Usability and users’ health issues in systems development2003Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The figures of reported health problems in computer-supported, administrative, work are alarmingly high and increasing. The main health problems are visual discomfort, repetitive strain injuries (RSI) and stress-related disorders. Some important risk factors are poor workstation design, constrained work postures, repetitive work and long hours of computer use every day. Others are high demands, poor control over workload and work pace and poor relations to management and colleagues. There is also evidence that poor design and usability of the computer systems as well as technical problems with the computer add to the pressure perceived by the user, which may in its turn cause stress-related disorders.

    Systems (software) development is often technology-driven and the design and contents of the resulting system shapes the work situation, including factors affecting the users' health and well-being. There are numerous examples in the literature describing how poorly designed systems fail to support the real work practices, introducing new ones that are inadequate and more time-consuming. Thus these, supposedly supporting, computer systems get in the way of efficient and effective work, adding a burden on the workers rather than helping them out.

    This thesis tries to describe some of the relations between the systems development process and users' health complaints, in a work context. I also discuss whether or not the concepts of usability and user experience can be used to address users' health issues in the systems development process. The main results indicate that although usability must be addressed, it is not sufficient. Occupational health issues must be explicitly integrated in systems development, and be given priority. This thesis also describes some potential methods and techniques for doing that.
