Older adults are living longer and more fulfilled lives, and they desire to live as independently as possible. However, independent lifestyles come with risks that are complicated by chronic illness and impairments in mobility, cognition, and the senses. A primary goal of the TigerPlace eldercare facility is to help residents manage illness and impairments and stay as healthy and independent as possible. In this paper, we describe a multidisciplinary project to investigate the use of sensor technology to provide early identification of problems in mobility and cognition. The technology will be evaluated within the TigerPlace facility.
