I recently bought myself a gyropoint mouse, and have been using it as a head-tracker (in a desktop environment). It performs admirably, but isn't so useful in modern games.

The setup involves sticking the mouse to a hat - whether it's on top of your head, or on a visor makes little difference - it performs admirably either way (see the tracer for a commercial implementation). However, as the mouse doesn't track roll, so tilting+turning your head results in movement in the y-axis, and depending on how your head moves, you do often end up with a cursor drifting upwards or downwards during use.

Other than that, the gyro drift is almost unnoticable - the specs say ~1 degree / minute, which is far less than the user-induced roll-based drift.

In IL2: Sturmovik, the mouse proved fantastic at general tracking around the sky, although again the roll-drift caused major problems, and in default 'looking forward' mode, normal head movements caused quite distracting bounces (when mounted on my hat's visor, you could see the view bouncing around in time to my heartbeat as the veins in my head sent tiny vibrations). Other problems were visible when I moved my head past the maximum cockpit viewing point - the view onscreen would stop rotating, so as soon as I started moving my head back to center, the onscreen view would too, and I'd end up with alignment problems.

It would be FANTASTIC if someone could write a utility to add some deadzone, movement limiting and a proper re-center key the same way cam2pan does it. I've been looking at doing so and thanks to DirectInput bypassing any system hooks, this will require writing a device driver, which I'm not looking forward to.

In Windows, the gyropoint is excellent - even when mounted to your head; imperceptable lag, fast updates, and it's incredibly accurate (sometimes too accurate - see my comment about my heartbeat getting picked up).

For the moment, however, I still think cam2pan or TrackIR is your best bet for games like IL2.

Glen, did you leave the mouse intact in the shell?

While I did take the thing apart to see if things could be miniaturised, when testing, the unit was 'as bought', and was stuck to my visor with an elastic band; I'm wondering if you could sell a hat with proper 'mounting positions'.

When located on top of my head (or inside a hood), I had to jam a bit of paper into the front-optical sensor to stop it thinking it was on a surface.

I had hoped that I could do what the boost technology guys did, and take the gyro out and connect it with a longer cord, but from looking at the guts, it was soldered and glued on pretty tight.

PS Please excuse the hideous grammar in my original message; I think editing for correctness inside a form submission textarea generally leads to more incoherent language.

This is exactly what the VRTracker and GyroTracker are from cwonline and vrealities.
