Rule-Based Talking Service to Elderly at Home for Efficient Mind Sensing

Our research group has been studying mind sensing, which is to externalize the inside of elderly’s heart as a sentence using a chatbot. However, our previous research lacks expandability because it is tightly coupled between specific services, and we can not easily add or change the setting of questions from chatbot. In this research, we propose a new service that asks questions based on rules. The rules consist of two parts, the condition part and the action part. The condition part defines the conditions on when, where, and what kind of event occurs to perform mind sensing. The action part defines the contents of specific questions such as what message is sent to which user. The proposed service makes it possible to ask more systematic and flexible questions, and it can be expected to capture various minds of the user. Currently, we use the proposed service for various applications on a trial basis.
