A Closer Look At The AimTrak (with video goodness)
bkenobi:
If a second LED bar were used on the bottom of the screen, would these problems be reduced? What if the LED's were located at the 4 corners of the screen? I don't know how the algorithms work explicitly, but the goal should be to have the gun work from any location as accurate as possible IMO. If more LED's are needed, add them! :dunno

I suspect its a tradeoff between number of led, and distance from screen. Remember the board is already aimed upwards. If there was a bar at the bottom as well, the eye would have to aim forward, and we'd have to stand back alot further.
I'm happy with the current setup.
bkenobi:
Hmmm, that's probably true. Good point.

Yes ok but- modern arcade guns use sensors all around the screen - and you can stand close. So whats different?

That's not true. The camera doesn't always have to have a second set of markers in view simply because they are there.
The logic would go something like:
See both: Average position
See top only: aim is below
See bottom only: aim is above.
Obviously it's more involved at code time, but that would be the starting point. This, BTW, is why you can get closer in the arcades.
