    Hello Greg, my headset has yaw drift , my ps moves start pointing straight forward at the start of launch of steamvr but after some time they start pointing diagonally, they move diagonally when moving forwards or backwards , same for ps move used for head tracking , if there a way we can for example tell all the ps moves to go forward in the direction the HMD is pointing at ? or anything else ? thanks , listening to any ideas

    Greg i found this comment of yours in a talk about drift , if im correct:

    “Hi,
    Yes. calibration drift is caused by headset. i am thinking all the time how this can be solved but realistically I am not able to determine difference between head rotation and drift.
    There are 2 possible options for this:
    1. Perhaps Kinect One (not sure if 360) will look at head orientation and make correction. I am bit afraid of it as it might be not reliable and result will be worse overall.
    2. You will have extra controller on your head that will be drift-free. This can be for example daydream. Perhaps PS Move but I am not sure how well it would work.

    Greg”

    about that last option you said , i already use a ps move on my head for positional tracking , would it be too hard to compare rotation to values of head ps move rotation and have an optimal non drifted image? using the ps move for both position and rotation is a no though because when we do that the image will be horribly jittery i think , makes up for a bad vr experience

    hi. yes. that is what I am going to do. but not sure when 🙂
    so you are saying you tried ps move alone for orientation and it was not well ?
    i would imagine even in such case it would be helpful as it would rather be used for correction, not to replace phone’s orientaiton.
    however for daydream or joycon perhaps this will give much better result. will know it when I test it.

    @Greg,
    I am using joycons and all of them exhibit some sort of yaw error, or a flat out yaw drift… if getting a daydream controller for a reference point can work, I will purchase it.
    Especially since even though the PS3 Move Controllers seem to be a “perfect” solution (color tracking for Kinect as well as IMU with magnetometer), it apparently also gives yaw drift.
