Abstract: Systems and methods are provided for measuring and identifying real-world tremors in order to calculate and display an anti-tremor in a virtual reality world. A system may identify a tremor in a body part, such as hands, and measure the tremor movement from, e.g., body sensors, to calculate an opposite movement and animate virtual hands performing the reverse tremor motion. Depicting inverse motions, such as an anti-tremor, may be used in a few ways to therapeutically train and exercise patients to better control their tremors. Providing a visual cue may help a patient interrupt the movement, as well as provide possibilities for therapy or training muscle memory and stimulating nerve and neuron recovery. By displaying an anti-tremor with virtual hands, a VR system may be used to help train or exercise body parts experiencing tremors.

Abstract: A system and method for generating simulated full limb animations in real time based on sensor and tracking data. A computing environment for receiving and processing tracking data from one or more sensors, for mapping tracking data onto a 3D model having a skeletal hierarchy and a surface topology, and for rendering an avatar for display in virtual reality. A method for animating a full-bodied avatar from tracking data collected from an amputee. A means for determining, predicting, or modulating movements an amputee intends to make with his or her simulated full limb. A modified inverse kinematics method for arbitrarily and artificially overriding a position and orientation of a tracked end effector. Synchronous virtual reality therapeutic activities with predefined movement patterns that may modulate animations.
