A Projection-based Augmented Reality for Elderly People with Dementia

As aging societies grow, researchers are actively studying care systems concerning the life and diseases of the elderly. Among these diseases, dementia makes it difficult to maintain daily life due to the degradation of cognitive functioning, memory, and reasoning, as well as the ability to perform actions. Moreover, dementia does not have a perfect cure, though therapy and care can slow its onset and provide patients with physical and mental support. In this paper, we developed a projection-based augmented reality system robot that can cover 360 degrees of space. We also propose an application that supports continuous monitoring of dementia patients to address the difficulties they face in daily life. The system is also designed to provide therapy applications, such as entertainment and spatial art, to provide mental care aids for the patients.
