public final Class EXTHandJointsMotionRange

The extension name.

The extension specification version.

XrHandJointsMotionRangeEXT - Describes the hand animation range of motion.

Enumerant Descriptions

• HAND_JOINTS_MOTION_RANGE_UNOBSTRUCTED_EXT This option refers to the range of motion of a human hand, without any obstructions. Input systems that obstruct the movement of the user’s hand (e.g.: a held controller preventing the user from making a fist) or have only limited ability to track finger positions must use the information available to them to emulate an unobstructed range of motion.
• HAND_JOINTS_MOTION_RANGE_CONFORMING_TO_CONTROLLER_EXT This option refers to the range of motion of the hand joints taking into account any physical limits imposed by the controller itself. This will tend to be the most accurate pose compared to the user’s actual hand pose, but might not allow a closed fist for example.
  • If the current interaction profile represents a controller, or other device that obstructs the hand, the implementation must return joint locations conforming to the shape of that device. If the current interaction profile is being emulated by a different physical controller, the implementation may return joint locations conforming to the shape of either the current interaction profile or the actual physical controller.
  • If the current interaction profile does not represent a controller, the implementation must return joint locations based on the unobstructed joint locations.
