Drift Correction Techniques
I'm working on a project where I will be using a motion capture tracking system to track the HMD (Oculus DK2). Now I'm curious because I could not really find any documentation on manual drift correc...
The paper you link is for deliberate misdirection of a walking user, allowing exploration of a whole village in a room the size of a basketball court. I would be (I imagine) important only to do this misdirection whilst the user is actually walking - it would be very awkward to be standing still turning head left/right and having the village slowly yaw around you.
For yaw correction (for 'true' direction) you need an external reference, such as magnetometer (DK1) or camera (DK2). As you say it might be odd to have the system correcting whilst your head is stationary. However with a properly calibrated tracker the yaw drift should actually be pretty small, and the user would (probably) be moving their head enough for you to sneak in the correction at any time without it being noticed.
