And maybe a bit different calibration methods like stepwise with images in which you need to look: and press a button everytime a position is held.. this should also give a good calibration (propably even better as with the current method)

step 1: set zero point

step 2: look left

step 3: look right

step 4: look up

step 5: look down

step 6: roll left

step 7: roll right

And between every step, set zeropoint..

a cool calibrationtool would be ofcourse to have it all in 3d(view) with spoken commands and let you look in specified directions..

hmm.. maybe I'll just try to see if I can do anything with the SDK..

also u are not ment to wear the vr920 when calibrating are u?

But having the other calibration process would IMHO be a better way of calibrating the vizor, as it goes through all the possible positions the wearer can use, also it would make it easier for the software to actually really tell what heading/valuerange is a specific heading..

But maybe it's not even possible to calibrate a singel axis on the chip, but the software should be able to handle it..

Still i found headtracking unsatisfying, i can use in only with smoothing tool - glovepie with smooth command. This makes head turning nice, but gives about 0.5 second lag between head rotation and tracking position. Maybe add smoothlike thinga in drivers?

You'd do it once, and forget about it...
