# Consuming FXRMotionControllerData
Taking a closer look at the <code>FXRMotionControllerData</code> declaration inside the Unreal Engine's <code>HeadMountedDisplay</code> module at <code>Engine/Source/Runtime/HeadMountedDisplay/Public/HeadMountedDisplayTypes.h</code>, figuring out the data structure might not seem very straightforward:

Both <code>HandKeyPositions</code> and <code>HandKeyRotations</code> contain 26 elements as defined by OpenXR's [<code>XR_HAND_JOINT_COUNT_EXT</code>](https://registry.khronos.org/OpenXR/specs/1.1/man/html/XR_HAND_JOINT_COUNT_EXT.html) and [<code>XrHandJointLocationsEXT</code>](https://registry.khronos.org/OpenXR/specs/1.0/man/html/XrHandJointLocationsEXT.html), etc.
Unreal Engine also provides an enum called <code>EHandKeypoint</code> naming the 26 joints, and the equivalent of <code>XR_HAND_JOINT_COUNT_EXT</code> as <code>EHandKeypointCount</code> inside <code>Engine/Source/Runtime/HeadMountedDisplay/Public/HeadMountedDisplayTypes.h</code> as follows:
