Cognitive Detection and Emotional Express System by Nostalgic Experiences

The problem of dementia for the elderly over 65 years old is an important issue that the government and the society urgently need to pay attention. In our research, the serious games that could record the performance of player and evaluate the cognitive ability in older people based on the problems caused by dementia.
