This paper presents a sensor network system for detecting multiple user activity in a home environment. Recognizing Activities of Daily Living (ADLs) by deploying sensors in the environment is very challenging. The task becomes more challenging when multiple inhabitants co-exist due to the noise introduced by the other users. The authors propose that each user carries an ID sensor and environmental sensors can recognize the user who activated them. The idea can effectively solve the event attribution problem for multi user activity recognition.
