Projector-camera based remote assistance system for the elderly: Design issues and implementation

As the elderly population grows rapidly, many social problems arise. In order to help enhance the lives of the elderly, many applications and devices have been developed. However, they are still limited to certain situations and lack some ability for remote assistance. Therefore, we present a projector-camera based assistance device for the elderly. It takes advantage of projection AR technologies and is easy to use for both the elderly and the remote helpers. We present some of the design issues and use cases for elderly-helping scenarios, and show prototype implementation and usage.
