Oculus Rift Drift

[Jeff]

What is the result when you the oculusExample.py script included with Vizard?

I tested it just now with the oculusExample.py script. Please note that I am not using the position tracker at the moment, just the hmd's gyro.

I did not notice a fast yaw drift. If there was a drift it was slow. However what I see is the orientation often freezes, then when tracking resumes the orientation is not what it should be.

Using the vizconnect tool I could observe a yaw drift as well as the "freezing" of the gyroscope outputs. I wonder if the lack of the position camera has something to do with this?

I've posted a video of what this looks like. Hopefully this helps explain what is happening.

If Vizard is running at a stable 75 fps then it maybe a hardware or driver issue if it was working well before. If you have not, try updating to runtime 0.8, Vizard 5.3, and latest GPU drivers. Also, make sure you meet the recommended Oculus hardware specs.
