Ambient assistive living system using RGB-D camera

One of the main problems that are being addressed intensively in modern societies is the ageing of population. Today's challenge is to allow elderly people to remain autonomous at their home as much as possible. Currently, one of the active research fields is the development of an assistive living system (ALS) that aims to support people at home. This can help elderly people to stay at home as long as possible, which consequently satisfies elders and reduces the health care cost. In this paper, we propose a simple and efficient way to track and recognize basic elderly activities using a single RGB-D camera. The main benefit of this method is the low cost and the effortless deployment and installation, as well as an overall recall of 97%.
