Mobile Robotic Telepresence (MRP) systems incorporate video conferencing equipment onto mobile robot devices which can be steered from remote locations. These systems, which are primarily used in the context of promoting social interaction between people, are becoming increasingly popular within certain application domains such as health care environments, independent living for the elderly and office environments. In this review, an overview of the various systems, application areas and challenges found in literature concerning mobile robotic telepresence is provided. The survey also proposes a set terminology for the field as there is currently a lack of standard terms for the different concepts related to MRP systems. Further, this review provides an outlook on the various research directions for developing and enhancing mobile robotic telepresence systems per se, as well as evaluating the interaction in laboratory and field settings. Finally, the survey outlines a number of design implications for the future of mobile robotic telepresence systems for social interaction.

This article presents the results from a video-based evaluation study of a social robotic telepresence solution for elderly. The evaluated system is a mobile teleoperated robot called Giraff that allows caregivers to virtually enter a home and conduct a natural visit just as if they were physically there. The evaluation focuses on the perspectives from primary healthcare organizations and collects the feedback from different categories of health professionals. The evaluation included 150 participants and yielded unexpected results with respect to the acceptance of the Giraff system. In particular, greater exposure to technology did not necessarily increase acceptance and large variances occurred between the categories of health professionals. In addition to outlining the results, this study provides a number of indications with respect to increasing acceptance for technology for elderly.

This article presents a method for measuring the quality of interaction in social mobile robotic telepresence. The methodology is in part based on Adam Kendon's theory of F-formations. The theory is based on observations of how bodies naturally orient themselves during interaction between people in real life settings. In addition, two presence questionnaires (Temple Presence Inventory and Networked Minds Social Presence Inventory), designed to measure the users' perceptions of others and the environment when experienced through a communication medium are used. The perceived presence and ease of use are correlated to the spatial formations between the robot and an actor. The proposed methodology is validated experimentally on a dataset consisting of interactions between an elder (actor) and 21 different users being trained in piloting a mobile robotic telepresence unit. The evaluation has shown that these tools are suitable for evaluating mobile robotic telepresence and also that correlations between the tools used exist. Further, these results give iportant quidlines on how to improve the interface in order to increase the quality of interaction.

In this paper we focus on spatial formations when interacting via mobile robotic telepresence (MRP) systems. Previous research has found that those who used a MRP system to make a remote visit (pilot users) tended to use different spatial formations from what is typical in humanhuman interaction. In this paper, we present the results of a study where a pilot user interacted with ten elderly via a MRP system. Intentional deviations from known accepted spatial formations were made in order to study their effect on interaction quality from the local user perspective. Using a retrospective interviews technique, the elderly commented on the interaction and confirmed the importance of adhering to acceptable spatial configurations. The results show that there is a mismatch between pilot behavior and local user preference and that it is important to evaluate a MRP system from two perspectives, the pilot user’s and the local user’s .

The field of mobile robotic telepresence for social communication is in rapid expansion and it is of interest to understand what promotes good interaction. In this paper, we present the results of an experiment where novice users were given a guided tour while maneuvering a mobile robotic telepresence system for the first time. In a previous study, it was found that subjective presence questionnaires and observations of spatial configurations based on Kendon’s F-formations were useful to evaluate quality of interaction in mobile robotic telepresence. In an effort to find more automatized methods to assess the quality of interaction, the study in this paper used the same measures with an addition of objective sociometric measures. Experimental results show that the quantitative analysis of the sociometric data correlates with a number of parameters gathered via qualitative analysis, e.g. different dimensions of presence and observed problems in maneuvering the robot. The implications of this form a basis upon which a methodology for measuring interaction quality can be obtained.
