Abstract
A fall prevention solution based on using smart cameras to access environmental hazards in patients' vicinity is presented. Contrary to most technical solutions that detect falls when the damage is already done or shortly before, our solution does not focus on analysing individual behavior shortly before the fall. We rather focus on the part of fall prevention that has shown to be the most effective in care: environmental awareness around the patient. Smart cameras are used in patients' rooms to understand patients' environment and detect conditions that may lead to a fall. We provide a framework that allows care givers to selectively define areas of interest from pictures of the room, and action to be detected and notified about. Events are then sent to care givers for each action detected. To preserve patients' privacy, images are processed in the camera and only an interpretation of the scene is sent to a server in the cloud. The server then forwards notification to the care givers' phone along with a silhouette of the action detected. Our first results demonstrate accurate detection of actions previously defined and real-time notification through the whole chain camera-cloud server-care giver.
