Abstract: A computerized method for correlating features of a user's motion in a VR-based exercise with specified populations includes the step of tracking a user's motion in a VR-based exercise with a hand controller. Based on a set of datapoints obtained from a sequence of positions of the hand controller, the method extracts a dynamic range of the user's motion. Based on the dynamic range, the method determines a velocity, an acceleration of the user's motion. The method determines the coefficient of variation for the velocity and the acceleration. From the acceleration and velocity data, the method calculates an initiation of the user's motion. The method calculates a combinatorial statistic from the coefficient of variation for the velocity ad the acceleration. The method determines a set of features of the user's motion represented by the combinatorial statistic that correlates to another combinatorial statistic associated with a specified population.
