Sharing big display : développement des technologies et métaphores d'interactions nouvelles pour le partage collaboratif d'affichage en groupe ouvert

Abstract : Screens have invaded our daily life. Amongst them, large displays are becoming increasingly present in public places. Sometimes, a few interaction are proposed to the users, but most of the time they are simply used as static displays. So, how to interact with these large displays and especially how to allow multi-user interactions? Of course, we have to define rules for collaboration: what we have to do if several people consult the same information at the same time? How to allow a newcomer to become aware of what there is to see when users have already "transformed" the display by their current use?First, our work consisted in testing instrumented multi-user interactions, based on a head tracking system, during a collaborative information seeking task, on a large display. In this part, we have highlighted the importance of the concept of "floating vision". Then, our research focused on the development of a head tracking system allowing intuitive interactions, without needing neither a special equipment nor individual calibration. Our system supports several users (up to six) simultaneously interacting with individualized information on a large display. Finally, we present the study of performance gain within a context of multi-user competitive consultation of information. We compare the benefit of an adaptive display (information move in front of users who are focusing on them), with a standard display. This study is based on user experience (UX) analysis. Thus, we were able to identify the first recommendations about interaction metaphors allowing intuitive interactions with a large display in an open group context.This research was devoted to highlighting the feasibility, interest and proposition of initial orientations concerning the design of multi-user interactions with large public displays based on a head tracking technique.
