Researchers at the University of Tsukuba found that elderly participants preferred three types of communication options when messages related to their self-disclosure were conveyed to others through a mediator robot: requesting-support type, concealing type, and recording type. Robots equipped with these communication options considerably reduced the anxiety felt by the elderly participants.

Tsukuba, Japan—Social Mediator Robots (SMRs), which facilitate communication by mediating messages among people, are considered to prevent isolation in elderly individuals. To avoid isolation, it is crucial for the elderly to talk about their daily problems to others (self-disclosure). SMRs that support such self-disclosure are being researched and developed.

The research group has been developing SMR design guidelines. The present research investigates how SMRs should convey self-disclosure messages from an elderly person to another party. First, an online survey was administered to 720 participants aged 65 and over, and 589 valid responses were received. After analyzing the data, it was found that three types of communication options were preferred by the participants: "requesting-support type," "concealing type," and "recording type." It was further shown that the most appropriate communication option depends on the recipient, the content of the message, and the gender and personality traits of the elderly sender. A second experiment was conducted with 36 new participants aged 65 and older. The results showed that when the mediator robot was equipped with these communication options, the participants' anxiety in self-disclosure was considerably reduced.

These findings provide useful guidelines for developing robots and AI systems for the elderly.
