Low Vision use with TrackIR

[DustinWright]

Hi All,

I have a dream, a dream to fly! Well, can't do it in real life because my eyesight is so poor. So, I enjoy PC games. Anyway, love the idea of TrackIR. If I could get it to zoom in my view exponentially rather than in a linear fashion, that may make it possible for me to use TrackIR to play flight sims, instead of my bioptic glasses. I need to be able to read labels on switches on the panel. Those are the glasses with telescopes in the lenses that you see dentists and surgeons wear.

The manual does not seem to tell me how to do this, can anyone help?

This brings a new problem though, if I'm zoomed in way way high, the slightest movement of my head creates wild gyrations in the view, what can I do about that?

Thanks!

Hello!

You can edit just the z axis to increase the positive sensitivity. Directions and information on editing the curves can be found in our manual, section 5.8.1.3 (Motion curves).

I can't figure this out. Can someone please take me under their wing and show me how to make it so when I move towards the monitor, the view zooms in exponentially?

I do not understand the curves, nor the manual. Honestly, it's just over my head. Please help. I'm not asking you to do it for me. I'm asking you to teach me how.

Thanks

Could I get some help please?

The curves represent degrees of movement in real life (x axis) and degrees of movement in game (y axis). If you have a dot on the origin (0,0), a dot on (3, 5), and a dot on (5, 10), that means that fir the first 3 degrees you move in real life, each will translate to 5 degrees in game. Additionally, when you move the 4th and 5th degrees in real life, those each correspond to 10 degrees in game, so by the time you hit 5 degrees in real life, you've moved 35 degrees in game.

To make something slow at first and then exponentially increase, your curve needs to look like a parabola (similar to the graph of y = x^2). To make it smoother, it should look more like a logarithmic graph (y = log2x)

Hey Dustin,

Here are some images showing different curve options. Hopefully this will help you understand how the curves impact motion.

First, for reference, here is a profile with no scaling. The in-game motion here would be scaled 1:1 to your actual head movement. (It's hard to tell, but each of the dots is at 1 on Y.)




Here is the Z curve on my flight profile:




If you wanted something similar to mine, but with more scaling when you lean forward, you bump up the curve like this:




If you want a truly exponential curve, it would look something like this:




But that would be way too fast. I think what you really want is what we think of as "progressive" scaling. It's like the beginning of an exponential curve--the more you move your head off-axis, the more it scales up. But unlike exponential, we clamp it down to keep the motion from getting unmanageably fast. This kind of curve could look like:




Or, if you want it to "ramp up" a bit quicker, you can increase the steepness of the curve incline:




I would personally scale back on the latter two a bit, and lower where the curve levels out on Y from 5 to somewhere around 3-4. But I made it kinda large, so you could get the idea.

Hope this helps!
