Controller Data
The Oculus SDK provides APIs that return the position and state for each Rift Touch controller.
This data is exposed through two locations:
ovrTrackingState::HandPoses[2]
: Returns the pose and tracking state for each Rift Touch controller.ovrInputState
: The structure returned by ovr_GetInputState
that contains the Rift Touch button, joystick, trigger, and capacitive touch sensor state.
The controller hand pose data is separated from the input state because it comes from a different system and is reported at separate points in time. Controller poses are returned by the constellation tracking system and are predicted simultaneously with the headset, based on the absolute time passed into GetTrackingState
. Having both hand and headset data reported together provides a consistent snapshot of the system state.
