Monitoring bed activities via vibration-sensing belt on bed

The aging issue has become an important issue of the world, mostly because the aging body makes elderly people in high risk. Since falling is a common accident when getting off bed and bed activities can help estimate sleeping quality, it is desirable to monitor bed activities for elderly people sleeping on beds. In addition, the deployment should be simple for the practicability. In this work, a simple vibration-sensing belt is deployed on the bed to collect signals about how users interact with the bed, and corresponding algorithm is developed to analyze signals for monitoring bed activities for users.
