Pretty much, I am using the Oculus Rift with the leap, but the leap must be on the desk.
So I am using the blinking IR LEDs on the Rift to calibrate the Leap Motion, calculate it's pose relative to the Rift, and the Leaps IR blast sometimes reflects off the Rifts plastic shell and ruins my blob detection.
It performs relatively well, but it would just be nice to have. If the Leap had the ability to disable the LEDs and a quarter inch camera mount, the Leap could be sold as a IR camera AND a Depth camera. Like what Intel is doing with their RealSense camera.
