Design of Coimagination Support Dialogue System with Pluggable Dialogue System - Towards Long-Term Experiment

摘要

In this paper, we design a dialogue system which aims to support elderly people's cognitive function with a conversation by face to face. We have a hypothesis that a kind of group conversation method which is called Coimagination Method (CM) would have merit for a human at a perspective of cognitive function. However, current CM aims to be designed to provide balanced group conversation among participants. Hence, the method has mainly focuses the group conversation, hence it has some limitations such as user have to join the specific location. But, elderly people sometime face difficulty because of some physically or mental problems to do it. In this paper, we try to design a chat system which provides a one-to-one conversation between human and system which is based on the essence of CM and copes the above limitations. In order to design the system, at first we consider an experimental design which would be conducted remotely during long-term as a system requirement, then we design a system which meets the requirement. Moreover, we also develop a prototype system in order to confirm the feasibility of proposed system design.
