ABSTRACT
We experimentally investigated users' reactions toward an on-screen agent appearing on three different types of media: a 42-inch television, 17-inch display, and 4.5-inch mobile PC. Specifically, we observed whether the users accepted the agent's invitation to a Shiritori game while they were engaged in given tasks. The results showed that most participants who received the invitation from the on-screen agent appearing on a 4.5-inch mobile PC accepted the agent's invitation, while most participants did not accept the invitation from the agent appearing on the other two formats. Therefore, the mobile PC appears to be an appropriate media for an on-screen agent that is required for interaction with users.

Investigation of users' reactions toward various kinds of artificial agents: comparison of an robotic agent with an on-screen agent
UAHCI'11: Proceedings of the 6th international conference on Universal access in human-computer interaction: users diversity - Volume Part IIWe experimentally investigated users' reactions toward an on-screen agent appearing on three different types of media: a 42-inch television (120 cm away from participants), 17-inch display (80 cm), and 4.5-inch mobile PC (40 cm). Specifically, we ...
Can users react toward an on-screen agent as if they are reacting toward a robotic agent?
HRI '09: Proceedings of the 4th ACM/IEEE international conference on Human robot interactionOur former study showed that users tended not to react to an on-screen agent's invitation of a Shiritori game (a last and first game), but did to a robotic agent. Thus, the purpose of this study was to investigate the contributing factors that could ...
Comparing an On-Screen Agent with a Robotic Agent in Non-Face-to-Face Interactions
IVA '08: Proceedings of the 8th international conference on Intelligent Virtual AgentsWe investigated the effects of an on-screen agent and a robotic agent on users' behaviors in a non-face-to-face interaction, which is a much more realistic style than the face-to-face interaction on which most studies have focused. The results showed ...
