Walk Navigation System Using Photographs for People with Dementia

Dementia occurs in every country of the world, especially in developed nations. Since such spatially and cognitive impaired people lack the ability to grasp positional relationship between landmarks, we have developed a walk navigation system using photographs of landmarks to benefit them and their families. Our system provides a photograph of the next target landmark to the mobile devices of cognitive impaired people. It can also identify points where cognitive impaired are likely to get lost. Our system can also support such tasks as taking tickets by photographs and animations.
