Oculus Rift on a Motion simulator, offsetting to the chair

Hello,

I'm currently working on a motion simulator to use together with the Oculus Rift goggles.

Imagine feeling the virtual world accelerations with the Oculus rift on.
It is one step closer to virtual reality 🙂

This requires to make the Oculus moves relative to the moving chair instead of the ground.
I already got the Oculus goggles working without picking the chair moves.
It was tested and working but I now need to build my motion simulator.

The motors are on their way so I hope to share my experience soon.

You can find more information on this project on:

Motion Drift will help the user to avoid motion sickness by giving the user the feelings that his brain waits for.

Thanks to the Oculus team for the amazing experience.

I am looking forward to the video and the method you came up with on how to cancel out the platform movement.

Thanks for your enthusiasm KydDynoMyte.
We (my friend and I) made a custom version of the Oculus library to change the orientation before it is made available to the game.
We use a sensor placed on the chair to compute the actual orientation of the head relative to the chair.

The results are above expectations, the orientation picked by the game is very stable when moving the chair and leaving the head in the same position, while the head moves of are still smoothly reproduced in the game.
I hope to upload a video soon of the test of the stabiliser.

At the moment we still don't have a motion simulator but the hardware is ordered and plans are almost ready.
So I had to test it on my desk chair on the Tuscany demo of Oculus which is a just a landscape with a house.
It is really disturbing to feel the chair accelerations without seeing the expected reaction in the oculus rift, it feels like being really drunk !

This means the feeling of presence should be amazing once the game environment will be in sync with the chair moves.
We can't wait to test it.

Nice work. I've heard of people wanting to cancel it out with software only. I thought mounting a 2nd set of sensors to the platform and taking the difference would be easier, and also cancel out any extra movement/slop/vibrations not intended. I am still surprised it works so well. I would of attached an optical tracker to the platform myself, because I never could of got this to work. Bring on the motion platforms!

Hello,

You can now find a couple of videos of our stabilizer without the Oculus rift googles but still explaining a bit how it works.

A video will the Oculus rift will follow, stay tuned.

That is a great looking racing/flying sim rig. It sounds like you know what you're doing - good luck with the project.

http://simprojects.nl/diy_motion_platform_v.htm Gene Buckle of www.f15sim.com just showed me this. (A cheap DIY motion sim - also check out the motor rumble device, to simulate engine rumble and noise - he just hooked it up in his flight simulator last night and let me fly it around - too kewl!)

mtbs3d.com/phpBB/viewtopic.php?f=3&t=4123 I am looking into that LEEP VR I lack practical 3d knowledge, I have found some good links, but I am not sure if they are the ones you were talking about. Would you mind direct linking me to them? :oops:

Thanks for the cheering grodenglaive ! 😉

We are very excited to put everything together.
We hope to have a fully functional motion platform with stabiliser once our DK2 will arrive, I ordered on the first or second day, lets hope we will get it in July (in Belgium).

I will of course keep you guys posted.

Hello cleverusername,

Looks cool indeed.
I only have a Saitek pro yoke and it lacks force feedback so for my first test I used a racing game instead with a logitech G27. The force feedback improves the sens of presence (immersion) and together with the Oculus Rift it was fun to see the character hands on the wheel reaction the exact same way. I thought I had gloves on 😛

As you can see the user can still use the Oculus goggles but if the chair moves it is not picked by the game.
