    Hey everyone,

    Soooo. Motion compensation. Here're we go again, huh?

    Okay so I've read through a huge amount of threads here about this issue, and I was wondering what you guys thought about this (although I know I'm by no means the first one to think about it, but wanted to give it a try).

    When using a WMR device, in this case my HP Reverb with inside-out tracking, I was wondering if it would be able to work smoothly in an enclosed 3DOF sim.

    Quick draft of what I had in mind:

    A few notes/considerations:

    1) This would be conceived for flight simulation (P3D), flying commercial planes with little vibration or movement (compared to race driving or combat fights).

    2) The panels would be made out of extremely lightweight materials like foam board panels.

    3) There could be any type of symbols, colours or shapes on the inside-facing sides of the panels to help the camera sensors (+ enough light).

    4) Disregard the practical aspect of not being able to get into your seat for now, this is more of a proof of concept at this stage.


    My main interrogation:

    I know the Reverb also has built-in inertial sensors like an accelerometer, gyroscope & magnetometer. How much do you think they would influence the visual sensors? Which one has priority in case of conflicting data?

    I would love to discuss this with anyone interested.

    Let me know your thoughts.

    Hi Luca. I just finished my 2dof project. Everything is working well. A lot of fun. I use this with a projector as well as the Rift S. While using it with the Rift I am getting nasty motion sickness which I think is probably caused by lack of motion compensation. I am going to try and rig up some sort of temporary enclosure to see if it helps. I might just use a large rubbermaid bin or something

    Some people are very susceptible to VR sickness, particularly in things like race games where you have a lot of stuff moving in your near, medium and far field of vision. But that aside a lack of motion cancellation on a large axis movement rig may add to VR sickness, but not so much on a small axis movement rigs. The more common cause is that the motion profile is not refined enough and the brain perceives conflicting cues from the VR visual and motion cues. A VR motion profile should aim to be precise and fast, so less is more in terms of reducing big axis movements.

    Ok. I am still tweaking things. I don't get any sickness while in VR only (without the movement). I also feel fine with movement and the projector screen. I am going to try turning the movement way down and see if it helps.

    I hope I can sort this out because VR and motion together is amazing fun.
