④ The user is not moving even though the user's normal idle time in a chair has
been far exceeded.
⑤ The user is wondering around instead of doing something specific.
⑥ Assume that these cases are when the user is feeling lonely.
⑦ Find images that can decrease their loneliness at specific times of the day.
⑧ Transmit these images to the ambient display.
This scenario is expressed in Fig. 1.
Fig. 1. Scenario Environment
RFID tags are attached to objects such as appliances (refrigerator, water purifier,
stove, etc), furniture (chairs, bed, and sofa, etc) and other household goods to receive
the information through the RFID reader that will be attached to the user's wrist. The
purpose of the system is to interfere with the user's loneliness using the acquired
information.
4 Definition of Lonely Cases
Situations to be judged as loneliness of the aged are presumed largely in two kinds.
First, it is a case that the aged do not do anything for a long time and another case that
the aged do only one thing for a long time on the contrary to the previous assumption.
Also, the case, in which the aged do not do anything for a long time, can be classified
into a case in which no RFID tag information comes in since they do not anything and
