Description

Enum Description

XR_BODY_TRACKING_FIDELITY_LOW_META

This value indicates that the body tracking runtime uses a simpler algorithm or less input to estimate the body pose in a way that trades off pose quality for system performance. For example, low fidelity may not accurately track a user’s elbows.

XR_BODY_TRACKING_FIDELITY_HIGH_META

This value indicates that the body tracking runtime uses more advanced algorithms or more inputs to estimate the body pose. For example high fidelity may track a user’s elbows.

The runtime may support a variety of fidelity options for body tracking expression. The application can request a desired fidelity, and the runtime will attempt to use that fidelity to provide body tracking for this application.
