But its not practical because at certain locations of the pointer, the camera will only be able to see one LED (ie one of the four LED groups) and would not know which one its looking at unless there is active control of each LED as in the Sega system.

Or if each LED group had a different visible configuration, which is possible with the rotated L-shaped emitter clusters I previously mentioned.

Just ask Johnny Lee  ;D




BTW, What if you had an extra AimTrak facing the user that tracked the GUN?  add an IR LED to the gun that was in a position that could only be seen by the AimTrak facing the users and wouldnt interfere with the sensors in the gun..

That wouldn't work, because it would only see the position of the gun and not where it was pointing.

I said in addition to the one already IN the gun.  Then it know where the gun was pointing and where from.  Thus you could move or hand the gun to your short little brother.

Okay, I see what you mean - but I see another problem in that approach...
The CCD would not be able to distinguish between depth and height, as holding the gun lower would look the same to the sensor as being closer to the screen (this is assuming the CCD is absolutely perpendicular to your floor and not tilted even 1degree).
