    Would you consider my 2/3dof as small axis?

    It is not the number of axis but how far axis actually move in physical space, for example like an actuator driven 6DOF compared to my compact 3DOF.

    My rig should only move a few inches in any direction so will just have to test once I have completed the build thank you though will let you know how it goes

    For slow cars No need, but if I try a F1 car, alone the gear shift or decelarion without breaking have to set vr view again and again. So if I have understand right, the virtual tracker does not for simtools, only for mover. So I have to use the wmr controller right?
    When I mount these to left besides the wheel and i will look to the right apex, do you think the inside out tracking will be track the controller?

    will these openvr driver affect the openvr api dll in game folders which I have patch for amd fsr and Nvidia nis?

    Did anyone successfully use motion cancellation with HP Reverb? (G1 or G2)??

    These things don’t handle translation very well without significant amounts of drift over time.
    I think the only way to have real rig position feedback would require a vision based position sensing.

    That is something for @yobuddy to consider.

    I use it with the G1.
    Both with SRS and the Witmotion device and with FlyPTMover using its built in software solution. Works great.

    Hi Guys,
    We will eventually have a Motion Cancellation Addon Api for v3.
    I already have a few test apps, but not a lot of testing so far.
    upload_2022-4-29_10-46-27.png

    I'm thinking something like open track may be a good option here.
    Mounting led's to your rig is just easy.

    This is really why I think an API is needed as there could be a lot of ways to attempt motion cancellation.
    Chat soon,

    Ive got the G2 . after they came out with the new cable they released an update that has seemed to have fixed the drift. also have installed opexr has made the issue of running 90fps a thing of the past. openxr has been an astounding marriage with g2 software absolutely am hooked .

    but the question i would have is that with the G2 and a seat mover for my motion rig, would it be worth to use motion cancellation? or would it made things odd?

    If you already use your rig with VR and don't notice anything odd, then likely your axis movement range is small enough to get away without motion cancellation, I don't bother with motion cancellation on my compact rig.

    But there is nothing wrong with running motion cancellation on a small axis movement rig, it is more a case of being worth the effort or not when often there is only a marginal gain. It is a different story for large axis movement rigs, which really benefit from motion cancellation.

    yup i understand the large motion but what does motion cancellation do? does it tilt the world
    I am curious to try this on my rig. the question i have, is the number on the angel of degrees are translatable from simtools degrees of motion converted in exact number to this software? is it that simple to use this software?

    The witmotion device mounted to my rig seems to work extremely well. Perhaps the v3 addon could try using this as well? SRS doesn't play nice with simtools and AMS2 on my system. (Whenever I have them all running, something simtools is controlling doesn't work (one of wind, SFX, belts). This only happens when SRS is running in the background. No idea why...)

    For sure!
    A really good reason to have these as addons, is we can try different things fairly easily.
    Once we have a motion cancellation plugin working, we can probably re-use most of the motion cancellation addon for many different hardware or software solutions with slight changes.

    Above is a test app for a virtual tracker, where SimTools directly controls the offsets.
    You simply put in the parameters from your sim.

    So say your sim can roll a total of 20 deg left and right, once the app knows this range, it can translate the motion inputs to a offset for the virtual tracker.
    Or that's the idea anyway, really not sure how it will match what the sim is doing at the time.
    But with a fast enough sim, it should work fairly well, and it can't drift at all.
    Smoothing and delay could be added also should it be needed.

    As the chair pitches back to simulate surge, so does your head, and in the game your now looking at the ceiling in the car. lol
    So the app makes a virtual tracker that essentially eliminates the pitch (caused by surge) from the headset.

    That will B SRS creating a port conflict with SimTools, as the two can't use the port for game data at the same time. Best to simplify your software stack.
