Abstract: A virtual or augmented reality based system for assessment and measurement of reaction time is disclosed. In various embodiments the system, methods, and computer program products relate to assessing and measuring a reaction time of a patient/user in virtual reality (VR) or augmented reality (AR) environments. The VR/AR system may provide a sensory stimulus to the patient/user in the VR/AR environment, determine a plurality of motion parameters, and determine a reaction time based on the plurality of motion parameters by applying a time window selection model. In various embodiments, a time window shrinkage model may be applied after the time window selection model.

Abstract: Adjustment of training protocols in virtual reality (VR) or augmented reality (AR) environments based on biofeedback are provided. In various embodiments, motion data is collected for a user while the user performs a training protocol in a virtual environment. A biometric measurement is collected for the user while the user performs the training protocol. The motion data and the biometric measurement are provided to a learning system at a remote server. The learning system determines an adjustment to the training protocol based on the motion data and the biometric measurement. The adjustment is provided by the learning system and is applied to the training protocol. In various embodiments, the adjustment, the motion data, and/or the biometric measurement may be logged in an electronic health record.

Abstract: A therapy and physical training system, comprising one or more movement sensors each of which positioned on a corresponding body part of a user, a first computer on a processor of which an application is running and a head mounted housing which is configured with a display on which images generated by the first computer are visible to the user. The application is configured to receive inputs from each of the sensors or from a second computer in data communication with each of the sensors, the application also configured to generate, in response to a real-time disposition of each of the corresponding body parts during performance of an exercise related body movement, a virtual reality object viewable by the user, the object being indicative of an additional body movement to be made by the user in order to conform with a user-specific exercise program.

Abstract: A virtual or augmented reality based tracking system for assessment of postural sway is provided. In various embodiments, positional data are collected from a user from a headset and/or one or more hand sensors. The positional data is processed to determine the center of mass of the user. In determining of the center of mass, positional data may be given a higher or lower weight compared to other positional data. A virtual reality environment is presented to the user through the headset and may be altered to simulate unbalancing of the user. The raw position data and center of mass are sent to a remote server. A report of user sway is generated from the center of mass. Nausea reduction may be implemented by narrowing a field of vision of the user.

Abstract: A virtual/augmented reality-based system for guiding patients through rehabilitation exercises and providing real time feedback is disclosed. In various embodiments the system, methods, and computer program products relate to guiding and measuring neck and shoulder motion, specifically protraction and retraction motions. A virtual reality environment includes a fixed object having a guidance feature and a moveable object having a complementary shape to the guidance features. Whether the fixed object is in a complimentary orientation to the movable object is determined. When the fixed object is in a complimentary orientation with the movable shape, an indication is presented to the user to perform a motion. A plurality of sensors determines a plurality of measurements relating to the motion of the user. Whether the fixed object is in a complementary orientation with the movable object is determined based on the plurality of measurements.
