Hands-free collaboration using telepresence robots for all ages

The use of telepresence robots brings the impression of physical presence to remote collaborations, which is beneficial in terms of establishing a closer relationship in a short time. However, operating a robot requires substantial cognitive effort. This can cause problems in practical situations involving older users, where the cognitive load interferes with the main task that needs to be performed. We have developed a telepresence robot system that addresses this problem by lowering the barriers preventing the operation of a robot. Its basis is the concept of an "observation window" that allows the robot to be operated without using hands or having to wear additional devices. This lightweight, less intrusive technology is expected to be desirable even for older users. This poster describes the mechanism and implementation of our system and reports its effectiveness in practical use by people of all ages, including older users.
