Hand Interaction Profile
The hand interaction profile is designed for runtimes which provide hand inputs using hand tracking devices instead of controllers with triggers or buttons.
The hand interaction profile allows hand tracking devices to provide commonly used gestures and action poses. Enable this OpenXR interaction profile to expose the <HandInteraction> device layout within the Unity Input System.
OpenXR Specification about Hand Interaction Profile will be updated here when it is available.
Available controls
The following table outlines the mapping between the OpenXR paths and Unity's implementation:
| OpenXR Path | Unity Control Name | Type |
|---|---|---|
/input/grip/pose |
devicePose | Pose |
/input/aim/pose |
pointer | Pose |
/input/pinch_ext/pose |
pinchPose | Pose |
/input/poke_ext/pose |
pokePose | Pose |
/input/pinch_ext/value |
pinchValue | Float |
/input/pinch_ext/ready_ext |
pinchReady | Boolean |
/input/aim_activate_ext/value |
pointerActivateValue | Float |
/input/aim_activate_ext/ready_ext |
pointerActivateReady | Boolean |
/input/grasp_ext/value |
graspValue | Float |
/input/grasp_ext/ready_ext |
graspReady | Boolean |
| Unity Layout Only | isTracked | Flag Data |
| Unity Layout Only | trackingState | Flag Data |
| Unity Layout Only | devicePosition | Vector3 |
| Unity Layout Only | deviceRotation | 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.
