Development of Hand–Eye Coordination Analysis System Using Mixed-Reality Technology

As Taiwan is about to enter a super-elderly society (the elderly over 65 years old account for more than 20% of the total population), how to delay disability and dementia in the elderly has become an important issue. Increasing the use of toys and games for the elderly delays their disability. Therefore, we developed three 3D interactive games for the elderly using mixed-reality (MR) technology. The three games were designed for hand-eye coordination, including digital cognition, object shape recognition, and color recognition ability. The reaction time was recorded to analyze the elderly’s reaction ability when playing the games. The questionnaire survey results showed that more than 83% of the elderly were satisfied with the use of MR equipment. More than 87% of the elderly accepted the interactive mechanism of MR while more than 80% felt that the three games improved their reaction ability.
