Skeleton tracking for serious games and real-time medical diagnosis

Physical rehabilitation of people with reduced mobility implies to monitor the movements of the patients during the rehabilitation sessions, so to individualize the therapy patient by patient. A serious-games company, NaturalPad (NP), would like to develop a cheap real-time markerless skeleton tracking device ensuring diagnosis assistance of neuromuscular and articular pathologies among reduced mobility persons such as elderly, post-stroke and persons affected by disability. In this way, the goal of this device is to precisely assess 3D body joints coordinates in real-time, that will be used to format accurate indicators about articular capacities of the patient during a physiotherapy session. These indicators, such as the Range of Motion (ROM) of each articulation, will be printed on a Graphical User Interface (GUI), so the physiotherapist can monitor the evolution of the patients pathologies. After giving details about related studies, we will explicit technological requirements and project constraints. Last we will define a benchmark process of existing skeleton tracking algorithms and cheap motion capture devices. The results will allow us to evaluate if there is an enough accurate camera/algorithm combination to deal with our issues.
