Abstract: A system for determining a quantitative accuracy of a test movement relative to a reference movement includes a display output device, a memory, and a processor operatively connected to the display output device and the memory. The memory stores motion capture data and programming instructions. The processor executes the programming instructions to determine a quantitative accuracy of the test movement relative to the reference movement. A method, executable by the processor, for determining the quantitative accuracy includes receiving, with the processor, motion capture data that includes the reference movement and the test movement. The motion data is split into individual movements, and the test movement is aligned with the reference movement. The processor computes a quantitative accuracy of the test movement relative to the reference movement, and generates, with the display output device, a visualization representative of the test movement. The computed accuracy is encoded into the visualization.
