How do you like me in this:user embodiment preferences for companion agents

Abstract

We investigate the relationship between the embodiment of an artificial companion and user perception and interaction with it. In a Wizard of Oz study, 42 users interacted with one of two embodiments: a physical robot or a virtual agent on a screen through a role-play of secretarial tasks in an office, with the companion providing essential assistance. Findings showed that participants in both condition groups would prefer to interact with the robot companion, mainly for its greater physical or social presence. Participants highlighted advantages that this physical form of companion would afford in comparison with the virtual companion, in terms of communication and interaction. Other differences in the user’s perception of the embodiments are reflected in proxemics and adaptation of the user’s speech when talking to the companion. This work provides useful results that will inform future development of embodied agents as artificial companions
