| hello, i'm currently doing my research project on the vr920 and i have found a problem.
i am monitorizing the yaw, pitch and roll when i move the glasses. i have created a program in matlab that shows the variations of each of them in degrees when i move. the problem is that when i move the glasses horizontally on a table (no rolling it), about 20-30 cm, i find a deviation of around 15 degrees in yaw only. i understood that it should be constant. otherwise, how do i diferenciate whether i'm moving horizontally or rotating? is it a problem of the glasses?
thanks in advance

| | I may be misunderstanding what you're doing, but have you made certain that there are no metal fastners and hardware in/under the table near where you're conducting your experiment with the glasses? Chris

| yes, there is nothing near the table that may interfere.
it would be extremely helpful to know how the glasses obtain the values of yaw, pitch and roll exactly, so we could see why one of these values (yaw) varies. is there any possibility of having access to the source code of the IWRGetTracking function?

| Sorry I can't exactly understand what is your problem, Yaw tracking in VR920 heavily dependent on magnet sensor.
Basically VR920 headset have accelerometers and magnet sensor(s), you can try to read raw data from accelerometer X,Y,Z and magnet X,Y,Z from GlovePie software, just use in script:
vr920.RawForceX - to obtain raw accelerometer data (the same for Y,Z)
and
vr920.RawMagnetX - to obtain raw magnet data (the same for Y,Z) |
