Interaction Source State. Try Get Pointer Pose(SpatialCoordinateSystem) Method
Gets the available pointer poses, such as the user's head gaze, eye gaze and each motion controller's pointer pose, for the timestamp when this state snapshot was taken.
public: virtual SpatialPointerPose ^ TryGetPointerPose(SpatialCoordinateSystem ^ coordinateSystem) = TryGetPointerPose;
SpatialPointerPose TryGetPointerPose(SpatialCoordinateSystem const & coordinateSystem);
public SpatialPointerPose TryGetPointerPose(SpatialCoordinateSystem coordinateSystem);
Public Function TryGetPointerPose (coordinateSystem As SpatialCoordinateSystem) As SpatialPointerPose
The coordinate system in which to express the pointer poses.
The pointer poses.
When targeting a spatial interaction, such as a hand gesture, motion controller press or voice interaction, apps should choose a pointing ray available from the interaction's SpatialPointerPose, based on the nature of the interaction's SpatialInteractionSource:
- If the interaction source does not support pointing (@"Windows.UI.Input.Spatial.SpatialInteractionSource.IsPointingSupported?text=IsPointingSupported" is false), the app should target based on the user's head gaze, available through the Head property.
- If the interaction source does support pointing (@"Windows.UI.Input.Spatial.SpatialInteractionSource.IsPointingSupported?text=IsPointingSupported" is true), the app may instead target based on the source's pointer pose, available through the TryGetInteractionSourcePose method.
The app should then intersect the chosen pointing ray with its own holograms or with the spatial mapping mesh to render cursors and determine what the user is intending to interact with.
This method will return null if the specified coordinate system cannot be located at the moment.
