public final Class EXTHandTrackingDataSource

The extension name.

The extension specification version.

XrHandTrackingDataSourceEXT - Describes the hand tracking data source.

Description

The application can use XrHandTrackingDataSourceEXT with XrHandTrackingDataSourceInfoEXT when calling CreateHandTrackerEXT to tell the runtime all supported data sources for the application for the hand tracking inputs.

The application can use it with XrHandTrackingDataSourceStateEXT when calling LocateHandJointsEXT to inspect what data source the runtime used for the returned hand joint locations.

If the XR_EXT_hand_joints_motion_range extension is supported by the runtime and the data source is HAND_TRACKING_DATA_SOURCE_CONTROLLER_EXT, then it is expected that application will use that extension when retrieving hand joint poses.

Enumerant Descriptions

• HAND_TRACKING_DATA_SOURCE_UNOBSTRUCTED_EXT - This data source value indicates that the hand tracking data source supports using individual fingers and joints separately. Examples of such sources include optical hand tracking, data gloves, or motion capture devices.
• HAND_TRACKING_DATA_SOURCE_CONTROLLER_EXT - This data source value indicates that the hand tracking data source is a motion controller. The runtime must not supply this data source if the controller providing the data is not actively held in the user’s hand, but may still provide data if the runtime is unable to detect if the controller is not in the user’s hand, or a user selected policy changes this behavior. Unless specified otherwise by another extension, data returned from HAND_TRACKING_DATA_SOURCE_CONTROLLER_EXT must behave as HAND_JOINTS_MOTION_RANGE_UNOBSTRUCTED_EXT.
