Through the application of TANO Intelligent Body Motion Assessment (CAREPIT) of TANO Interactive Rehabilitation Assessment and Training System (Hong Kong OSH Version) in Occupational Safety and Health (OSH) assessments: (1) heavy lifting postural assessment and (2) patient transfer postural assessment, we can make OSH assessments become more objective and precise. A set of stretching exercises is input into the system. It can analyse the motions and output a score based on the performance of the users, so that staff and elderly can practice the stretching exercises safely and precisely, as well as promoting the OSH.
