Certain aspects provide a method of generating a physical activity model, including: receiving, via a motion capture device, motion data corresponding to a plurality of key states associated with a physical activity sequence; for each respective key state in the plurality of key states: determining a plurality of joint positions associated with the respective key state; determining a plurality of body segment positions associated with the respective key state based on the plurality of joint positions; determining a plurality of inter-state differentiation variables for the respective key state; determining one or more state characteristic metrics for the respective key state; and determining a classifier for the respective key state based on the one or more state characteristic metrics; and defining a physical activity model based on the one or more state characteristic metrics and the classifier associated with each key state.

Physical activity quantification and monitoring

Certain aspects of the present disclosure provide a method for assessing the performance of a physical activity, including: recording motion capture data while a training subject demonstrates a physical activity sequence; identifying one or more primary body elements based on the motion capture data; deriving one or more path characteristic metrics based on a state variable set and the one or more primary body elements, wherein the state variable set defines the state of a body at any given time; and defining an ideal activity path of the physical activity sequence based on the one or more path characteristic metrics.

Scoring metric for physical activity performance and tracking

Systems and methods for facilitating gaze tracking based on multiple images are disclosed. A gaze tracking system includes an optical module configured to receive illumination from a target and provide a background and tracking channel outputs, the background channel including ambient illumination and the tracking channel including ambient and controlled added illumination at a targeted range of wavelengths. The background and tracking channel outputs are provided to an imaging module configured to provide an associated set of background and tracking images to a processor module to facilitate gaze tracking. Controlled illumination of the target may be provided by an illumination element, in conjunction with the processor module, to facilitate gaze tracking.
