We propose a system that estimates the health condition of older adults at home based on the responses in which they talk with a robot. The system actively elicits the clue for estimation of the health condition by not only observing a living environment passively but by talking to older adults. As a first step, to survey how older adults react to the voice-call robot, we conducted a user study in a situation that the robot talks to older adults who were about to leave a chair. In this paper, we report the user study and discuss appropriate talking.
