    Hi guys!
    A week ago I finally finished the build of my 2 DOF motion simulator. I did this as a school project, which I have to present in front of a jury in June. When I started this project I immdiatley had the idea to use virtual reality (I own an Oculus Rift), but I don't have a lot of experience with VR. What are the most important things to take into account? All tips are welcome :thumbs.

    When it comes to VR and motion simulators less is more, you want fast precise movement, normally over less of a range of a motion profile, not big ponderous axis movements.

    For small axis movement rigs you can get away without motion compensation, which is where the movement of the rig is measured and deducted from the VR HMD view.

    On large axis rigs you will need motion cancellation: https://www.xsimulator.net/community/faq/openvr-motion-compensation.373/

    One of the challenges when using motion cancellation is that a VR HMD determines it 3D position by a combination of tracking and internal sensors. VR drift can be an issue when using motion cancellation and high frequency transducers (buttkickers) can mess with tracking and sensors.

    Hi noorbeast!
    So the main thing were I'll probably need to look at, is making smaller and preciser movements. I'll first try to this, if this isn't working I'll take a look at motion cancellation.
    Thanks for replying and giving me these helpful tips!
