QUICK SUMMARY

Force sensing sticks aren't as unreal as one might think. With special consideration to them in Storm of War, they would become far more realistic in many ways than other joysticks.

BACKGROUND

I always dismissed force sensing for WW2 sims at first, in favour of moving sticks (G940 for example). A month or more ago I had a pleasant conversation with a British gentleman (a veteran of IL-2 multiplayer since it first came out). He had a force sensing joystick he had assembled from parts. It did not move at all, just sensed his imputs. He could tweak how far the range would be (that is, how much force was necessary to get 0-100% input into the game).

With normal sticks, there's a discrepancy in how much you move your stick and the one in the game moves in two ways: 1. The 'courve' we use to make our planes flyable with such limited movement range, and 2. when suffering compressibility and those things, the in game stick moves less than it should compared to the joystick, which moves easily to max (since there's not much resistance to stop it). If there was a conventional stick with very strong force feedback, and a good movement range, this could be solved.

For a force sensing stick those things are not an issue. Instead, if the plane does not turn enough with a certain strength of pull, one pulls harder until getting the desired result.

But there are still limitations. The 'pull harder to get the proper results' mentioned above only functions properly when trying to input less than 100% movement in a direction. Because the stick will give 100% at a certain weight (2kg for example). And since when flying normally it often happens that we want to do 100% turning, especially out of a dive in IL-2, the range will be limited by the maximum pull the stick will register (0-2kg means more than 2kg has no effect). Another problem is that if the stick has a range from 0kg to say, 8kg (a lot) then to turn under normal circumstances in IL2 you always have to pull 8kg, which is not good either.

THE SOLUTION

Storm of War needs to interpret input from force sensing joysticks differently. It must be possible to set it so that, under normal circumstances, maybe just 25% input from the joystick is 100% in the plane (normal/slow flight). Then, depending on the resistance the plane wants to offer, which depends on speed and airplane model (some are heavier in the controls than others), just like in force feedback, but instead of increasing resistance in force feedback motors, it requires more and more 'input' from the joystick (user pulling harder and harder if a force sensing joystick).

THE RESULT

The only limitation for realism in forces involved depends on how big the range/resistance of the force sensing joystick is. Some people have home built models, some are commercial models. There's a lot of possibility here to make it a great alternative to other types of joysticks.

The result will be that take off and normal flight (in easy to fly planes without much resistance in the controls) is easy and light. But when flying a heavier plane (Bf 110 at higher speeds) or in dives and so on, more and more input from the joystick is required, so the user must pull harder and harder to get the same input, until it's too much.



Suits pit building because the stick does not have to be tall or move around. Can then be center mounted easily (normal 'non tall' sticks are very unsuited to center mounting, sharp angles of the wrist involved when moving the stick around).
The unrealistic angle of the conventional sticks is avoided.
Is similar to control surface force feedback. When the plane goes faster and you have to push the stick forward to keep the plane from nosing up (typical situation), applying some trim will make you able to relax the pressure on the stick, just like real life. There's no hassle with a force feedback or other stick needing to be physically forwards to do it properly.


The lacking thing then is the same as any force sensing stick - the stick doesn't move as far as the real stick should (aircraft sticks back then moved very far often, just look in the cockpit of your plane in IL-2). But every stick so far lacks in realism in some way, and this is a good option. Force feedback in terms of vibrations and those things could help you feel buffeting when near stall even in a force sensing stick. Up to the manufacturers to come up with models that allow for a big range of force and force feedback.

This sounds interesting. However, it would seem odd to use a stick that doesn't at all move.

I think the best option would be a stick-rudder system that sat on the floor under your chair and which had an adjustable tension of 100 pounds or more based on the situation in the game (speed, compressibility, pulling G's).

That's not ever going to happen. Imagine a bowflex with potentiometers, lol!

Actually, I'm not sure that it will 'never' happen. Given the amount that some are willing to spend on gaming hardware, there may be a market for such a device, though it is likely to be expensive, and mechanically complex (it would probably need hydraulics).

Back to MikkiOwl's original suggestion, I don't think users of normal joysticks would like what you propose - it would have to be optional.

Remember this?

The hydraulic force feedback joystick was a promising prototype, that showed up at the 2009 Gamescom:

IMHOP, the joy itself looks terrific! Hope to get more news on this new piece of hardware soon:

that is a gay joystick...
what a mistake it was to tun on my sound..

I can´t agree more with you, regarding the sound! More than gay, I would say it's a Trekky gay joy! ;o) Those two 'reactors' look pretty similar to Enterprise spaceship's ones, don´t they?.

Never saw that before! Interesting. :)

Regarding the force sensing interpretation for SoW, it would obviously only apply to force sensing sticks (like Saitek XF-63 or whatever it's called) and never to any other type. :) But it really would make a major difference in realism/experience, and is not a complicated concept at all for implementation.

At Ubi's,

http://forums.ubi.com/eve/forums/a/tpc/f/23110283/m/2661077438

you can find more info concerning this joy. In short, 2 models, Falcon (no hydraulic effect) and Hawk (the one on the videos). Expected retail prices: 279$ and 389$ respectively. Expected release date: Sept. 2010, Ubi's Il-2 Moderator T_O_A_D dixit from a direct talk to Paccus people.

IMHO for that price the hydraulic effect has to be something from the outer space! And even then, given my 109 is absolutely earhtly, it will be a bit too pricey yet.

The problem: I'm always too curious about this sort of hardware, my two MS SWFFB2 are too close to retirement and Logitech G940 is, so far and IMHO, a bittersweet symphony given what you can read about it on this site and the web.
