Owing to the increase in the population of elderly people, the number of people suffering from mild cognitive impairment is increasing in several countries. Furthermore, family members of people with mild cognitive impairment, such as reduced function of memory, reasoning, and decision-making, undergo severe stress owing to difficulties in communicating with them. There are, however, few existing technologies to support learning this type of communication to reduce this stress. This study proposes a tool wherein an animated character resembles the behavior of elderly people with mild cognitive impairment in different scenarios to teach how to communicate with them. Fundamental experiments were conducted to confirm the validity of the proposal tool, and results showed that the tool successfully helped users learn how to communicate with elderly people with mild cognitive impairment. Furthermore, we demonstrated the advantages of using an animated character to depict the behavior of people with mild cognitive impairment. We believe the proposed tool enables the imagination of difficult situations and the understanding of communication with the elderly.
