Touch or Talk?

Abstract

This work is targeted towards the development of a recommender system that fosters the well-being of elderly people in their domestic environment. Since seniors can have a rather high barrier of using newer technologies, the interaction device utilized in such a system has to be selected carefully. This paper compares an anthropomorphic presentation of recommendations by a social robot with a graphical presentation on a tablet PC in terms of the perceived usability, the users' experience and the system's persuasion.
