title: User interaction in smart ambient environment targeted for senior citizen.
abstract: Many countries are facing a problem when the age-structure of the society is changing. The numbers of senior citizen are rising rapidly, and caretaking personnel numbers cannot match the problems and needs of these citizens. Using smart, ubiquitous technologies can offer ways in coping with the need of more nursing staff and the rising costs of taking care of senior citizens for the society. Helping senior citizens with a novel, easy to use interface that guides and helps, could improve their quality of living and make them participate more in daily activities. This paper presents a projection-based display system for elderly people with memory impairments and the proposed user interface for the system. The user's process recognition based on a sensor network is also described. Elderly people wearing the system can interact the projected user interface by tapping physical surfaces (such as walls, tables, or doors) using them as a natural, haptic feedback input surface.
