Our research group is conducting research of a system to support the lives of the elde rly at home. We developed "Rakuraku Video Service"(Rakuraku means easy.), a service that obtains information on the interests and preferences of elderly people and recommends YouTube videos based on this information. The purpose of this service is to help the elderly relieve stress and relax by watching videos. However, it has not been tested yet whether this service has such an effect on the elderly. We conduct an experiment to evaluate the service. In conducting the experiment, we will collaborate with a previous study, "PC-Mei" which aims to watch over the elderly and support their daily lives with a virtual agent. The experiment was conducted to obtain evaluations of watched videos and a questionnaire. From the results, it is clear that the service is useful in relieving stress among theelderly.
