C Specification

An application can create an XrHandTrackerEXT handle using xrCreateHandTrackerEXT function.

// Provided by XR_EXT_hand_tracking
XrResult xrCreateHandTrackerEXT(
    XrSession                                   session,
    const XrHandTrackerCreateInfoEXT*           createInfo,
    XrHandTrackerEXT*                           handTracker);

Description

Valid Usage (Implicit)
Return Codes
On success, this command returns
  • XR_SUCCESS

  • XR_SESSION_LOSS_PENDING

On failure, this command returns
  • XR_ERROR_FUNCTION_UNSUPPORTED

  • XR_ERROR_VALIDATION_FAILURE

  • XR_ERROR_RUNTIME_FAILURE

  • XR_ERROR_HANDLE_INVALID

  • XR_ERROR_INSTANCE_LOST

  • XR_ERROR_SESSION_LOST

  • XR_ERROR_OUT_OF_MEMORY

  • XR_ERROR_LIMIT_REACHED

  • XR_ERROR_FEATURE_UNSUPPORTED

If the system does not support hand tracking, runtime must return XR_ERROR_FEATURE_UNSUPPORTED from xrCreateHandTrackerEXT. In this case, the runtime must return XR_FALSE for XrSystemHandTrackingPropertiesEXT::supportsHandTracking when the function xrGetSystemProperties is called, so that the application can avoid creating a hand tracker.
