Microsoft Hand Interaction

Unity OpenXR provides support for the Hololens 2 Hand interaction profile. This layout inherits from <XRController> so bindings that use XR Controller and are available on this device (for example, <XRController>/devicePosition) will bind correctly.

This interaction profile does not provide hand mesh or hand rig data. These will be added in the future.

For more information about the Microsoft Hand Interaction extension, refer to the OpenXR Specification.

Available controls

The following table outlines the mapping between the OpenXR paths and Unity's implementation:

OpenXR Path	Unity Control Name	Type
/input/select/click	select	Boolean
/input/squeeze/value	squeeze	Float
/input/grip/pose	devicePose	Pose
/input/aim/pose	pointer	Pose
Unity Layout Only	isTracked	Flag Data
Unity Layout Only	trackingState	Flag Data
Unity Layout Only	devicePosition	Vector3
Unity Layout Only	deviceRotation	Quaternion
Unity Layout Only	pointerPosition	Vector3
Unity Layout Only	pointerRotation	Quaternion

Note

Some Unity controls don't correspond to an OpenXR path. Unity expresses Pose data as individual elements, whereas OpenXR expresses poses as a group of data. These additional controls contain Unity Layout Only in the OpenXR Path column. You can use this additional Pose data for more fine-grained controls. To learn more, refer to Pose data.
