Abstract [en]

GIS have been plagued by complicated interfaces for some time but is improving. This thesis researches whether an interface with a flattened hierarchy is better suited for a geographical information system rather than a ribbon interface. Two interfaces were built for a system used to supply geographical data to aircraft and Mission support systems. A pre-study was conducted with the existing users and developers to synthesize initial requirements and conclude what is troublesome in the existing system and the workflow process. It was found that there was a lack of consistency in the current system and that the workflow felt ad-hoc. Two prototypes were developed as add-in in Esri’s newly launched ArcGIS Pro and usability tested, one using the ribbon interface and one with the flattened hierarchal interface. Using the subjective workload NASA TLX questionnaire, time on task and a questionnaire regarding the participants’ attitude towards the interface, it was able to see how the workload, efficiency and attitude for the different interfaces were. The usability testing of these interfaces showed no significant difference in time. There was only one significantly difference for the workload, it was in the physical scale. Users that first tested the ribbon interface and later the flattened hierarchal interface found the second interface to be significantly more demanding physically. An attitude questionnaire showed also that participants felt that the flattened hierarchal interface was significantly more overwhelming and would be more discouraged to use it compared to a ribbon interface.
