    I have recently been able to take my rig to school and plug it in with the oculus rift setup they are using for research, and let me tell you, it's AWESOME! I was mostly concerned about the shaking of the oculus, however with a simple seat mover I didn't find a need for motion cancelation. Seems as though that would really only be a concern for 6 DOF? What I find most interesting though was that in VR it seemed as though my perception of speed was actually much less than with a monitor?? This seems very counterintuitive to me, but a friend who tried it as well got the same impression. Has anyone noticed the same thing? The only thing I can guess is that in VR you have less of the "peripheral" motion which is seemingly faster than what is center screen? Interested in your thoughts? @noorbeast IMG_8932.jpg

    The VR fixed horizontal FOV is significantly less than say a triple screen, though it is mapped a full 360 degrees so you can look anywhere, which is very different from a monitor. In addition VR does not have the contrast of onscreen movement against a static real world background.

    Personally I find the VR sense of speed more realistic, part of that being immersed totally in the game world rather than having a window into it.

    Ya that was the general line of thinking I had as well. Very interesting!

    I felt the opposite (VR more realistic) - but it depends on what you have been brought up to. My son a few years ago was always able to beat me in computer racing games, as he was brought up on them and had never raced or drove a real car. I always struggled as the feeling of speed and judging braking points on a 2D screen seemed very unatural to me and it was not until VR came out that my real experience came to the floor and I was then able to beat him :). I have also seen on-line articles were a Pro-driver was placed on a standard triple screen sim and struggled to feel comfortable and meet his times, but with VR he immediately said he felt at home and quickly came up to speed.

    @SeatTime great perspective! What is your racing experience? I have been out on the track maybe 3 or 4 times, and it was some time before I actually got my sim running so its hard for me to form a great correlation. I do think that VR definitely improves the overall immersion without question. I am still curious though, even though you get better track times and it feels more real to you, do you think a monitor feels faster than VR?

    It seems to me as though the overall biggest challenge when you are playing a game as opposed to reality is knowing when to brake when going into a corner. Somehow in real life we are able to just feel it, hence people who are perfectly capable of driving in real life play a game, and then quickly fly off a cliff upon entering the simulator, even with 2DOF. Seems like both the perception of speed and the perception of acceleration play into it. I'm curious what you think is the best way to combat this particular issue. Traction loss? g-seat? VR? harness tightening? 6DOF?

    Racing experience...., a bit of GoKarts, some rally driving courses and many years of track days and inter-club Supersprint competitions. Unfortunately I have never had the dollars to be at the pointy end of the field :(, but I do enjoy it and it was the need for more track time at a lower cost which got me into simulators in the first place. Does it feel faster on a monitor - never really noticed that, but it sure does not feel real, especially judging distances as I explain in my first comment. But my driving experience is what has driven me to keep adding more systems to my sim in a mission to make it as realistic as I can (I haven't finished yet - 4 more G-seat paddles to install :rolleyes:). VR, 6DOF, G-seat, Harness Tensioners and harpic Transducers (buttkicker) all add to realism in a layered way, bringing different nuances to the simulation puzzle. As for making me a faster sim driver :thinkI'm not too sure about that, as I think that the big movements can get in the way, the same way as it does in a real car, as you have to brace/adjust for the Gs and are therefore not as smooth as you could be. IMO if you want to be a fast Sim racer the following will help you: Good VR system (not really there yet - but its OK:)) Direct Drive wheel, a pedal set with a brake pressure sensor and a good G-Seat setup + maybe a transducer on the pedals. This will give you excellent fast/responsive feedback without the real Gs that can get in the way of driving smooth/fast. Is this the best setup for realism? Its pretty good, but adding real Gs with motion (the more real DOFs the better) gets you even closer to a realistic race car/aircraft experience. Just my opinion of course, but I hope it helps.

    Hey Matt - I'm really curious about that Stanley JumpIt. How long will it run your rig?

    I looked up the numbers and it's a 19 Ah pack in there. Brilliant idea for carting the seat around.

    Do you use that at home too or just when taking the platform to remote demos and such?

    for me jumping in VR was a way to learn track better and improve my laptimes dramatically. with cv1 i don't feel reducing of speed sense comparing to 1 flat big tv i was using before

    Sorry, I'm so slow to respond life's been crazy! Ya, I actually used that exclusively before I picked up a power supply and it works great! I would say that I get several hours of use before the low light comes on. I have never run it dead, as that generally damages batteries. Also, my motors pull around 10-15 amps between the two of them, so obviously it will depend on the setup. now I use this 30A power supply at home and it works like a charm, but the battery is great when I wanna take it places. Portability was a huge factor in my design, as I am working on a system to drive the motion with RC vehicles

    do often move your rig around?

    Hey Matt, thanks for the info! I'm just now building my rig but don't anticipate taking it places. I just thought using that battery cart was a really cool idea and was curious how it worked for you. I'm only building a 2dof for now and think I won't be overloading the circuits in my room. But if I do, a battery to shave peaks will definitely be in my future.

    Cheers!
