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.

Abstract: System and method for improving tactile sensitivity and precision/accuracy of motor control of the hand of a subject. A joystick is configured to provide commands to a computing device. The joystick includes a base, shaft, and a textured surface with a specified level of bumpiness. A computer-implemented exercise is executed, including presenting stimuli, including at least one target, to the subject via a computer display. The subject is required to respond to the stimuli via the joystick within a specified duration, including using the joystick to move a cursor to the target, and, upon reaching the target, disengage from the joystick. The subject's response to the stimuli is recorded, and a determination made regarding whether the subject responded correctly. The duration is modified based on whether the subject responded correctly to the stimuli. The presenting, requiring, recording, determining, and modifying are repeated a plurality of times in an iterative manner.
