Abstract

We reported that videophone conversation was effective in increasing psychological stability of individuals with dementia. We als developed an anime agent system to serve as a conversation partner for individuals with dementia. The computer screen showed an animated face resembling “a 5-year-old grandchild.” The agent was programmed to ask any of 120 pre-set reminiscence questions, automatically detect the ends of replies, and follow with new questions. In the third experiment, the remote multi-party conversation system Skype™ was integrated with the agent system. The agent participated as a presenter of conversation topics for the multi-party interaction. Three pairs conversed under two conditions: conversation of two subjects and a chairperson (human condition) and conversation in which the agent participated as a topic presenter to the above groups (agent condition). The quality of the conversation was scored by three evaluators. The average score of the evaluation was 3.9 (78 %) in the agent condition and 4.9 (100 %) in the human condition. With further improvement of this agent system, it will become practical as a topic presenter for multi-party conversation of individuals with dementia.
