I really hope that gt7 will include compatibility with immersion devices like :
-
buttkickers (physics related like
simvibe)
-
d-box like /
frex like motion systems (
rseat RS1,
rseat F1,
Vesaro...)
A lot of simracers have butkicker(s) and it's sad that we can't really use them in GT6 (yes we can use them but they are sound related and not physcis related like pc games with simvibe...). PD could sell a small "usb soundcard" that we can plug in the PS4 and that does the same thing as simvibe. I don't think it will cost too much
You can get a fair amount of motion from FFB signals, but it would be mainly, if not solely yaw. You could piggy back the ground vibrations as well. You'd need a circuit board(s) that can take the FFB signal that tells the circuit board in the wheel how much amps/volts to power the motion units, depending on what you're using based on the sort and design of the rig. Motors need power to move obviously, but the power signal is not sent straight through the USB cable to the wheel to the wheel motors. It is just a signal that is sent to the circuit board and then the circuit board uses the power from the wall outlet to power the wheel motors, based on it's interpretation of the signal coming into the board from the ps3.
A buddy and I have been designing one with an arduino board, but quality motors with enough torque are very expensive to get with a 360* range and you usually need at least six forms decent rig. That's all that is halting us right now. It couldn't be used to it's full potential with gt yet, though of course. Idk. We may be able to use the signal that emulates the feeling of the weight transfer...but there is no signal for body roll itself, weightless from lift, the body compressing to the ground or slamming from getting air, getting pushed back into your seat or getting pushed forward under braking, etc. There are not many sims that support all of this stuff anyways. It is super expensive and often used with a one off sim. I've seen make shift rigs, specifically a popular YouTube clip with one that sort of looks like a swing, but a feel race seat. Idk what sim he is using, but all of the motions are in reverse. He would brake and the chair would tilt him backwards, not forwards, etc. The entire unit swiveled with no forward back/right left motion. Just pivoting on a center axis.
I priced out a rig with six high quality motors without screens, computer, sims, etc. Would cost over 5k to do it. You need to build a steel or aluminum chassis, weld it, weld in six motors, build a platform to place on them, mount your seating rig on the platform properly and so on. And there is no way you would enjoy one screen with a motion unit. Your perspective on the screen would be changing to rapidly, which also happens in real life...but you have an entire, natural peripheral view. You need at least four more motors to at each corner of the platform to raise, tilt and rock it, too. So ten motors. If course there are many ways to build a sim rig like this, but if you're going to build one, it is silly to shell out cash for one that will work so-so. You'll end up not using it or it'll make you naucious. You could make ones that slide on tracks with lifting motors as well. Like I said, many ways to do it right. They're just all expensive
