Well, I think now we are understand each other
I don't know if this idea I have will really work, but as said before, maybe you can train your brain to associate the aproximation to the controls, as braking, and the separation, as accelerating.
Important: the movement should be just some milimeters, maybe 10 or 20 at maximun. When driving you wouldn't have more than that.
I think Frex movement is to extense. Since first time I saw a video years ago I thought that was not realistic, because it try to simulates the inertial force pushing your body forth and back, but it is not connected to the controls, forcing a strange situation where you can cleary see on the videos the big variation of distance between the driver and the wheel.
FD, by its side, has a better approaching, and that is a old and reliable solution (I think that Boeing was the first to make such system, I have no sure), but, under my vision, this system fits better with Flight Simulator than LFS or other racing game, because the transitions of a plane is always slower than a car, and then, that "mechanic bull" behavior is less evidenced.
I know, some of you have said it to me, and I knew you would do that, but believe me, I already knew that I have not much property to say something about FD, without have tested it. But what I can see on the videos, and what I can think about the system, is something with high probability of be wrong, in certain aspects.
The word is transition, as mentioned by Hallen before, is something that I suspect of FD. Suppose that you are in a flat street, like Autocross. You play with the accelerator, making a series of little taps on the pedal. Your car goes forward and stops, goes and stops, goes and stops. This causes inertial forces over your body, relatively big, and you feel it, but you know you are on the flat, not just because your eyes can see it, but because your labyrinth feels too, and send that information to your brain. But in FD you seem spun in the air, you see on the videos that the body rolls, like the mechanical bull, and I can suppose that it is not too right.
Ok, let me explain something, it is important: I have no intention to talk about FD anymore here. The unique reason that I talked about it, and put those videos for comparison, was to let well clear why I intend to try another approaching. So please, before someone think I'm here for bash the FD, I'd like to let very undertood that NO. I have nothing agains this company, I don't know anyone inside there, and me, being a industrial designer, have too much admiration by their products, their engeneering looks to be stupendous. Ok?
I'll back later to discuss more about my concept. What I want here is to make a brain storm with people who know what a simulator is, in the intention of achieve something more consistent, before start the prototype. And I also intend to make a step by step follow up here to share all experience.
See you later.
