Virtual living room system based on video call to connect nursing home resident and family moderately

Many senior citizens stay in a hospital or nursing home. When they part with their family, there is a risk of them suffering from delirium due to stress [1] [2]. Although video call probably reduces their stress, they may feel an oppressive feeling by constant video call, and also may be hesitant to take the trouble to call each time. The family live freely and have no strong connection with the other in the living room, but a person can start a conversation at any time by talking to another person, and the conversation will end naturally without clear termination signal. In this paper, we propose virtual living room system to connect distant people each other moderately using video call service. It provides only information that the other person is there when video call is disconnected, and connects video call by a belief voice word.
