      @@KarlGosling Thanos is strictly speaking correct - braking/accelerating are two sides of the same coin - it’s just a rate of change. If you accelerate you are subject to positive g in the longitudinal axis, if you decelerate you are subject to negative g in the longitudinal axis. Motion is relative. You are also spinning at enormous speed while hurtling round the sun as the entire galaxy hurtles through the universe but you don’t observe this speed because your frame of reference isn’t moving and the accelerations are imperceptible. The speed of motion doesn’t matter since it’s all relative anyway - it’s the rate of change (aka acceleration) that you feel. The error is in thinking the sim behaves in the same way as the car, you can only try to replicate forces as best you can. If you want to feel the vehicle deceleration, it is the exact reverse of how you feel the vehicle acceleration… I disagree with your assessment that negative surge is not accurate for braking.
      However, it has to be said - just do what feels good to you. For example for flight I use a setup that isn’t strictly accurate, but gives me the best sensation in flight… who cares as long as you’re having fun.

    there's actually 2 ways to do movement, you can replicate the car movement or you can replicate the g forces, and as both are exact opposites of each other it's a choice in which one software wants to use, so both ways of doing can be correct depending on what you are using the movement for

    It's just a matter of the position from where movement is determined during acceleration of the vehicle.
    If the observer is standing outside of the vehicle, both objects (occupant & vehicle) are moving in the same direction during acceleration, in relation to the observer.
    If the observer is inside the vehicle (as in: a camera mounted to the vehicle), the vehicle remains stationary (with the observer), and the driver/passenger moves backwards (in relation to the vehicle), until such time as both ground speeds match, at which point both vehicle and occupant become stationary again (when compared to each other).
    The problem we have with sim rigs, is that there is no forward movement, as the whole rig is sitting on the floor.

    • @Madkangaroo
      @Madkangaroo 4 месяца назад +2

      I think this should be the actual topic of the conversation. The thing with sim rigs is that there is no way to simulate the force of the seat pushing you forward that makes people feel like there's a force "pushing them back onto the seat", which is the consequence of the difference in accelerations between the seat and the person. I also don't think the phrase "being pushed back into the seat" is 'wrong', it's a matter of the frame of reference as you said.

    This all makes sense for flatscreen for sure. I agree that surging forward is the way for accelerating since you’ll feel the pressure on your back, however, in VR, motion compensation will be needed since it’ll look the opposite effect moving forward on acceleration. Braking, I also agree that moving backwards for braking isn’t the way since there’s no pressure to be produced on the body in the sim, best to use a seatbelt tensioner or just pitch down when braking.

  • @jaytoppo1670
    @jaytoppo1670 6 месяцев назад +4

    Spot on Karl, the driver is stationary and the car is pushing forward into the driver's back on acceleration, you're never being forced backwards as some seem to think, the car is forcing itself forward against the driver, the driver is "floating" within the car and not fixed and solid/rigid. A lot of sim folk don't really understand the dynamic of motion platforms with these levels of immersion as most can''t afford it or don't want to spend high levels of money on such equipment... a seat mover doesn't count because that concept of motion isn't correct, a seat never moves independently to the rest of the rig, it flexes but never moves. Well presented mate as it's not a subject that's easy to present due to the complexity of motion, even if it is only simulated whilst stationary/static.

      I'm actually running a Mk1 Prosimu T1000 3dof platform with the old SCN6 actuators with 100mm travel up front and 80mm travel on the sway/sideways motion mate, I've spent a long time tweaking and tuning to suit but as it's only 3dof means some sensations aren't quite as there as a full on platform but I'm managed to hit that sweetspot with it now. When watching rigs move, they'll move in what appears to be an incorrect movement however, the sensation it gives to the driver is relateable to the real movement, it's odd to look at when looking from an observer perspective and see these odd looking moves, to the driver it feels similar to the sensation to what you'd feel in real life so to speak...

    • @davidwei9806
      @davidwei9806 6 месяцев назад

      I agree. I find it interesting that it's not intuitive for most people.
      It's Newton's first law of motion - "An object at rest remains at rest, and an object in motion remains in motion at constant speed, unless it is acted upon by an external force".
      We are an object in the car. Our body will stay at rest until an external force acts upon it. That external force is the car moving forward. Upon that action, that's when we will start "moving" as well.

    @wickfut8917 6 месяцев назад +3

    It's when you start using the tilting of a sim rig to simulate acceleration and deceleration that it dose the opposite of what it should.
    on a rig you aren't in a moving vehicle so the sensations you get are basically variations of pressure from the seat against your back as it tilts in various directions.
    In a real car when you accelerate the car moves and you get the feeling of being pushed into your seat, the feeling of pressure between your body and the seat increases.
    In a simulator which tilts when you accelerate, the front of the rig raises and the rear lowers to use gravity to simulate the pressure your body feels during acceleration. The problem is during the initial transient movement of the rig while starts its tilt. The leaning back tilt of the rig to point you slightly upwards moves the seat away from your body giving a less pressure feeling between your body and the seat, which is the opposite to what you feel in real life.

    • @Zeeflyboy
      @Zeeflyboy 6 месяцев назад +3

      That’s where the longitudinal surge axis helps - you combine the initial push/pull from the surge for the impulse and transition into a tilt for the sustained force while washing off the longitudinal.

    • @KarlGosling
      @KarlGosling  6 месяцев назад +2

      Using pitch (tilt) is not good at all for simulating acceleration or braking, it can be used in conjunction with surge (as you do actually move forwards then) but otherwise just like with a seat mover it feels wrong... I used to run a seat mover but soon grew to dislike it and went back to no motion.

    All this is very weird in the sense that seat movers do move back... once you accelerate the seat inclines backwards, and it does seem to work and give a sense of acceleration. But perhaps what gives this sense is gravity that in that moment starts to act at your back since it's now inclined. Anyhow, no wonder this is a big topic of discussion (and argument)

    • @KarlGosling

    I don't have the problem where my surge platform should move (forward or backwards) as sadly I don't own the surge platform. However, I think I might understand where these comments come from. I can imagine 2 approaches to use the surge platform - First one, to imitate the move of the car accelerating. Second - to focus more on the g-forces imitation and compromise the real world. Now, this is sim racing so we have completely different actuator travel to what the car is doing - so that's the first challenge but also we have the personal feeling. We can see it for instance when it comes to FFB settings. There are so many of them and everyone tries to tweak it, so it feels more "real" for them. Additionally, in sim racing we have tools like wind simulator where even you made the video why this is a great tool (I have one, used your discount code and absolutely love it). Does the wind simulator exist in the real life? not really, not needed there. But things like wind curving is amazingly tricking our brain making us feel like the car is rotating while in the sim rig. I think with the constant battle for the immersion in the sim racing world there are tricks which do not make sense from the real life perspective but helps us to be more immersed. I am with you that if I had the surge platform, I probably would start from the settings you describe. However, my curiosity would make me try the backwards option as well to see how it feels. If it would make me feel better, more immersed, my body would feel that sort of move as closer to what I would expect in the real world - I would stick to that one which tricks my body better and I would have no problem with the fact it is working completely opposite.

    @nunofreitas1796 6 месяцев назад +3

    Good night dear Karl ,
    Of course when your car goes forward you never go backwards.
    However, excuse me if I'm not agreed with you,
    in simulation is exactly the opposite, in simulation we do not want to simulate what the car do, we want to simulate the sensations of driving a high speed car.
    So, in real life when you accelerate, in a fraction of second you have the sensation to stay behind because the seat is pushing you, in simulation you go backward and your eyes and brain make the rest of the trick.
    In real life when you brake, in a fraction of second you have the sensation to go forward because the car brakes before your body, besides if you haven't a seat belt for sure you go through the windshield,
    in simulation you go forward and if you have a multiple point harnesses secured in a place outside the motion system it will be the best sensation.
    Thank you, all good to you,
    happy new year

    Ok ......Try this...😃😃
    .i use the sfx100 with surge platform and my steering wheelbase is mounted on the outer and steady (4 actuators)frame. The seat and pedals are mounted on a moving surge frame with also mounted seatbelts on the outer! frame
    So when i brake ....the seat slides forward just a few cm (and then the seatbelt logically gets tighter )
    It really gives a braking sensation like being pushed out of your seat (also cause your upperbody comes 3/4/5 cm closer to the steering wheel)
    Acceleration is even more minimal... and better simulated with a little pitch when shifting gears
    Surge should ONLY simulate the braking in my opinion.
    i dont see so many rigs with this solution..... but i SURE recommend it
    Remember it is all about feeling
    AND when somebody uses surge under acceleration forward......MAN...its just stupid cause your platform moves max 2 seconds
    but the accelleration time on track to the next corner are WAY longer then that

    When you accelerate hard in a car, you're pushed back into your seat from G forces. Having the sim seat shove you from behind achieves the same sensation. When you brake hard your torso is thrown forward, hinged at the waist, when the sim seat jerks backward your torso is thrown forward. So that is the correct way to do it

      No mate you are not pushed back by G force you are always pushed forward (gravity just wants to keep you on the spot) and again when braking you are never "thrown forward" you are already moving forward and begin to slow down to match the new reduced speed of the car... this is momentum.

    • @imagebuff
      @imagebuff 6 месяцев назад

      You don’t recognize the forward pitch on braking or backward pitch on acceleration because your eyes are telling you the car isn’t pitching ( barely ), rather your back is feeling pressure from the seat (pitch up) or your hands pressure from the wheel and chest from the belts (pitch down). Your brain thinks there are gforces present. Works beautifully especially with well tuned surge sled coordination. Motion compensated VR sells this illusion much better than triples as it hides your room environment from your peripheral vision.

    They might be struggling to explain the G forces at play when accelerating forwards in a car. But they might not understand the effects of G forces when you're in a car, accelerating, braking and cornering. Either way it's funny and forgiving if that is the case.
    But if they genuinely refuse to accept what has already been observed and researched by scientists and universities, its not worth the time and energy to argue with them daily.

    I think some people think you go backwards when you get pushed in to the seat when you do a fast pull off but thats not at all how it works as your still moving forward with the car, you are just moving slower than the car so the seat is pushing in to you not you pushing in to the seat, but for some people basic physics is hard, get on a bus opr train and jump yopu will move with with it.

    Ha ha, love this discussion, so i am driving a van, in the back of my van i have unsecured item of furniature, when i accelerate the item goes backwards, or does it stay where it is until the back door makes contact? under braking the opposite happens.

    • @KmcK
      @KmcK 6 месяцев назад

      It stays in place (relative to Earth), until the back door makes contact. Note, that's assuming your furniture and floor are perfectly slippery (the grip of the floor would accelerate the furniture, just not as much as the vehicle if the furniture slides). Your furniture is moving backwards relative to the vehicle, but not the Earth - that's just because of where you're viewing it from. It would be like driving in your car, looking out the window and saying "the trees are going backwards" - the trees aren't moving (relative to Earth), you're observing from a moving vehicle.
      Another example is pulling a tablecloth so fast the plates and glasses don't move. If you were a lego-sized person holding on to the tablecloth, the glasses look like they're going backwards, when in truth you're going forwards and the glasses haven't moved (relative to the table/Earth).

    @rogerwennstrom6677 6 месяцев назад +1

    Good explanation! I hadn't really thought this through before, so this was educational.
    After thinking about it for a while theres one thing I'm not agreeing with though! Why should'nt you pull the cockpit back for braking?
    The less scientific reasoning:
    simply look at the video of how the bodies react to both acceleration and braking. Why would it be realistic to only simulate how your body reacts to acceleration and not at all simulate how your body reacts to braking?
    If you *would* pull the cockpit back during braking, wouldnt it look and feel the same as the video during braking? I think it would. So why leave that half out?
    Alternative semi-scientific explanation:
    the rig isnt a car, it is simulating the car by moving in a way that applies the the relative forces a car would exert on you... And the the surge actuator part has the potential to do this for *all* accelerative and decelerative forces. (temporarily atleast, but we'll get to that later)
    This means it is perfectly fine to move the rig backwards to simulate braking. It is just simulating the "delta" between the cars movement (acceleration or deceleration) and your body - regardless of if the virtual car is moving forwards or backwards. Again, it's not a car restricted to a short track, it is simulating the car :)
    ...
    Also, this video really has made me question how useful a motion rig like this can really be...
    After all, the simulation of acceleration can only be sustained for what, a couple of tenths of a second?
    So you could never have that proper "pushed into your seat" feeling really for more than a jolt unless I'm missing something obvious? Ive never driven a rig like that so I wonder how much it would actually add for me personally. (I am not dismissing it though without experience!!)
    Makes you wonder if inflating the seat and neck support to push it into your back could simulate constant acceleration to some degree though? :) (especially if using belts)

    • @imagebuff
      @imagebuff 6 месяцев назад

      You can pitch the rig backwards to simulate a bit of constant acceleration g force. It works as long as the visuals don't portray the pitch move. Requires motion compensated VR or flat screens moving with you in a dark room.

    • @KarlGosling

    • @rogerwennstrom6677
      @rogerwennstrom6677 6 месяцев назад

      @@KarlGosling Its ofcourse all up to you, but from a pure forces perspective applied to your body, my point is that pulling the rig backwards to simulate braking is equally correct as for example pulling the rig backwards when reversing from a stop, as you do now:
      If you'd shut your eyes, *you could not feel a difference* between reversing from a standstill or braking from a steady speed. The forces applied to you is the same. Therefore it makes sense that your rig should simulate both theese forces. (It will simply simulate the forces on you, due to the inertia between you and the simulated car)
      The reason it feels like youre being pushed backwards now (if you enable pushing the rig back for braking) is probably because you can *see* your monitors moving away, which is a fair point.
      But on the other hand, moving closer to your monitors when accelerating could be argued to be technically equally wrong, and it seems youre fine with that :)

    This all has to go with inertia ultimately. I love all of your videos Karl and have nothing but respect for you and all of the content you create but I'm at a loss with this one. Perhaps the most simple test you can do is to go and drive a real car, brake as hard as possible from high speed and see what happens, you will be thrown forward. Vice versa with acceleration. Granted these sensations are almost invisible at normal road speeds but we will agree to disagree on this one. I'm not here to argue and you are and will always be one of my favourite RUclipsrs and a brilliant guy in general.

  • @a92gsxdsm

    Yes. When you hit the gas pedal in a reall car the Gforce or force of gravity pushes you back in your seat. Braking will push you forward because of the negative gforce. Hence the requirement of seat belts as a safety feature.

    • @jooshwolfheart
      @jooshwolfheart 6 месяцев назад

      You are right but semantically wrong. G force is not the force of gravity. It is the ratio of the force applied divided by the force gravity. This just lets you have a sense of the magnitude of the force. The car accelerating is the force that is applied. This acceleration could be from speeding up, breaking, or turning.

You travel through space as everything else in space meaning the earth that we are standing on.
