Abstract
In Japan's super-aged society, which is characterized by a four-generation family structure, the number of cases in which the elderly living alone ends their life without sufficient sharing of family history are expected to increase. While the means of communication have been enhanced due to the spread of smartphones, many elderly people are still not good at using said devices. Therefore, in this study, we propose a system of support in recording of life history such as cooking recipes cultivated over many years of experience in which the elderly cooperates with their separated families.
