Dementia Screening System based on SNS Agency Robot We have developed the SNS Agency Robot that can be used for interactive communication between the elderly and the young via existing social media. We developed the Dementia Screening System by adding an AI conversation diagnosis method to the SNS Agency Robot. The feature of this system is that we could replace medical doctorxe2x80x99s examination of dementia with the Robot. The results of the examination by this Robot will be reported to people around the elderly by SNS using the original function of the SNS Agency Robot. We conducted evaluation experiments of this system with patients of Nagasaki University Hospital. As the result, we confirmed a strong correlation between the results by medical doctors and by the Robot.

Hospital Receptionist Robot v2: Design for Enhancing Verbal Interaction with Social Skills This paper presents a new version of robot receptionist system for healthcare facility environment. Our HealthBots consists of three subsystems: a receptionist robot system, a nurse assistant robot system, and a medical server. Our first version of receptionist robot, interacts with human at hospital reception, gives instructions to human verbally, but cannot understand what human says, so it uses a touch screen to get the response from human. In this paper, we design a receptionist robot that recognizes human face as well as speech, which enhances verbal interaction skill of robot. In addition, we design a reaction generation engine to generate appropriate reactive motions and speech. Moreover, we study which social skills are important to a hospital receptionist robot to enhance social interaction, such as friendliness and attention. We implemented perception modules, decisionmaking modules, and reaction modules to our HealthBots architecture, and did two case studies to find essential social skills for hospital receptionist robots.
