Abstract: Systems and computer-implemented methods for tracking movement of a subject comprise and perform the steps of: Obtaining depth image data of a subject's body during a predefined time period and tracking locations of a plurality of anatomical landmarks of the body based on the depth image data. In addition, a location of a predefined point is tracked in an environment, in which the subject is moving. The location of the one or more of the plurality of anatomical landmarks is adjusted relative to the location of the predefined point to obtain adjusted locations. A movement of the subject's body is determined based on the adjusted locations during the predefined time period.

Abstract: Systems and methods for analyzing whole-body balance comprise and perform the steps of: obtaining depth image data of a person's body during a predefined time period; tracking locations of a plurality of anatomical landmarks of the body based on the depth image data; estimating a mass center of the body based on a tracked location of each of one or more of the anatomical landmarks; and determining a stability of body, SoB, score based on a deviation of the estimated mass center over the predefined time period, wherein the SoB score is indicative of the whole-body balance.
