He's actually onto something here, though I'm not sure how well it would work in practice.

What he's getting at would work in a similar way to the tech demo that someone made using a wii remote, so that when you moved your head, the head traching follows and adjusts the field of view and perspective point to give an illusion of depth, though it's still displayed on a flat screen, and to any other viewpoint (like someone looking over your shoulder) it would look decidedly weird.

The problem I see is how then do you treat the pilots head - you would need to use the x/y/z translation axes as inputs for the faux 3d, and so would lose the 6 degrees of freedom we're used to using trackir/freetrack. we could still have 3dof, and I'm still not entirely sure how well this would work in practice. We would need to be able to map field of view to an axis, and then have some sort control via the x/y axis of the perspective point.

e: having re-read his comment, I think he just means the mapping of, say the z-axis of a trackir set to the fov setting. Much more doable than the idea I had. I'd still like some kind of control over the perspective point like I suggested though, it'd be... interesting to see the effects in this way, though it'd take a hell of a lot of configuring/fine tuning.
