Goal: VR setup on a Motion Platform - Using VR glasses within a Cabine which is moving in all degrees of freedom.
Problem: Many VR glasses (like the Oculus DK2) are using for head-motion-tracking (orientation tracking) a combination of IMU sensors and InfraRed LEDs and combine the information with sensor fusion. This does not work on a motion platform because the IMU sensors recognize the motion from the plattform like the user is moving the head. Result: The orientation becomes immediately wrong.
Possible Solution: Using the new HTC VIVE doing the orientation tracking and motion tracking with the two "base stations" only. Mount the "base stations" within the cabine of the motion plattform. With that the orientation is relative to the cabine and therefore correct.
Uncertaincy: Is the HTC VIVE really working WITHOUT any internal IMU? respectively does the HTC make proper head-motion-tracking (orientation tracking) with the two "base stations" only?
Possible ways to disable IMU on Oculus?
