Remarks

Windows Mixed Reality supports motion controllers in a variety of form factors, with each controller's design differing in its relationship between the user's hand position and the natural "forward" direction that apps should use for pointing when rendering the controller.

To better represent these controllers, there are two kinds of poses you can investigate for each interaction source.

The grip pose represents the location of either the palm of a hand detected by a HoloLens, or the palm holding a motion controller. On immersive headsets, this pose is best used to render the user's hand or an object held in the user's hand, such as a sword or gun. The grip pose is represented by the position, orientation and velocity properties directly within this type.

The pointer pose represents the tip of a motion controller pointing forward. This pose is best used to raycast when pointing at UI when you are rendering the controller model itself. The pointer pose can be accessed through the SourcePointerPose property.

Version history

Windows version	SDK version	Value added
1607	14393	Orientation
1709	16299	AngularVelocity
1709	16299	PositionAccuracy
1709	16299	SourcePointerPose

Properties

AngularVelocity	Gets the angular velocity of a hand or motion controller.
Orientation	Gets the grip pose orientation, representing the orientation of the user's hand as it holds a motion controller.
Position	Gets the grip pose position, representing the position of the user's hand, either directly or where it holds a motion controller.
PositionAccuracy	Gets the accuracy of an interaction source's positional tracking.
SourcePointerPose	Gets the pointer pose for a particular spatial interaction source, such as a motion controller, at a given timestamp.
Velocity	Gets the velocity of a hand or motion controller.
