## Detailed Description

The XrController is a tracked spatial node that tracks the position and orientation of an input controller.

Since this is a tracked node, its spatial properties should be considered read-only.

See also XrInputAction.

## Property Documentation

### controller : enumeration

Specifies the controller to track.

It can be one of:

Constant | Description
--- | ---
`XrController.LeftController` |
`XrController.RightController` |
`XrController.UnknownController` |
`XrController.LeftHand` | (alias for `LeftController`)
`XrController.RightHand` | (alias for `RightController`)

### isActive : bool `[read-only]`

Indicates whether the controller is providing input.

This property is true if the corresponding physical controller is present and tracking.

### jointPositions : list<vector3d> `[read-only]`

When using hand tracking, this property holds the positions of all the bones in the hand.

See also jointRotations and XrHandModel.

### jointRotations : list<quaternion> `[read-only]`

When using hand tracking, this property holds the orientation of all the bones in the hand.

See also jointPositions and XrHandModel.

### pokePosition : vector3d `[read-only]`

This property holds the position to be used for touch interactions. Typically, it will be the tip of the index finger when tracking a hand.

See also XrView::processTouch and XrView::setTouchpoint.

### poseSpace : enumeration `[default: XrController.AimPose]`

Specifies the pose of the controller to track, that is, the orientation and position relative to the physical controller.

It can be one of:

Constant | Description
--- | ---
`XrController.AimPose` | Used when aiming at something, such as with XrVirtualMouse.
`XrController.GripPose` | Used when grabbing something, such as when holding an object in the hand.
