US Patent 11948401 AI-based physical function assessment system

Various embodiments of devices, systems, and methods for providing AI-based physical function assessment recordings and assessment performance analytics for a subject are described. A series of video frames are obtained that include the subject. Computer vision techniques that use artificial neural networks may be applied to the video frames to: detect a Person of Interest (POI) and an Object of Interest (OOI) in the video frames; track movement of the POI and the location of the OOI in subsequent video frames; detect body key points; and detect postures and posture transitions of the POI. Physical function indicators may be calculated and function analytics provided based on the assessment.
