what is a light gun?? you mean a gun that uses light to use like a real gun?? I am unsure if that would even work with a projector but I think some years back somebody used one on a real big FPS Rig that shot back..

@The_Nephilim - [url]https://en.wikipedia.org/wiki/Light_gun[/url] Think back to old arcades where they had games like Duck Hunter - the controllers on those were usually light guns. Would it work or not? Honestly no idea - it probably depends largely on what technology the sensor is using and what kind of projector you are using, and whether the gun can handle the latency of a projector. For example, a DLP projector alternates between red, green and blue at different times, so a light gun sensor that depends on them being displayed simultaneously might not work (so avoid any designed to work with CRT monitors, though I don't imagine these will be common any more). A really old light gun like the ones used in Duck hunt that depend on the game drawing a white rectangle over the targets probably would work with a projector, but you wouldn't find any games that support it. Some newer light guns use IR emitters independent of the screen to triangulate their position (similar to the Wii remote and sensor bar). These would probably work ok since they don't care what kind of display is in use, but I don't know if there are any limitations like screen size or distance that may cause issues. I haven't seen one of the image capture ones the wikipedia article talks about, but it sounds like they would probably work, so long as their sensor can cope with the red, green and blue images coming in at different times. Personally I wouldn't go for one like this if there are alternatives, since changing the image on the screen even for one frame can be perceived.

Resident Evil: Dead Aim was an incredible light gun/GunCon2 game on PS2 that, unlike traditional 'shooting gallery' light gun games, you could roam around freely and then go into shooting gallery mode whenever you want ... that said, it sadly only works on CRT TVs and was specifically designed to work the way it did. Even the Wii FPSs that use IR aiming are specifically designed to look around at the edges and aim in the center, there are a few that are always aiming/turning but from the games I've played none of them really work while aiming down the sights like the older CRT versions did. On the Wii they're generally always 'off' and there's no way to calibrate them and on the PS3/SharpShooter it kept losing calibration. So from my experience with console light guns the old CRT type are the only ones that really work like a gun, IR being a close second if you can calibrate them ... as far as PC light guns go I have no experience with them but most of them look like they either rely on one or more IR sensor bars, which if you're using 3D Vision glasses could cause issues. Then there's actually controlling the mouse in a FPS, there's no 'aimbox' like on a Wii FPS that's designed for it, there's no moving reticle to follow where you're aiming. I just can't imagine it would work well at all constantly aiming at the center of the screen to keep from turning ... and even if you could get that perfect ADS point and shoot control like a GunCon2 on a CRT it all goes out the window when you add 3D Vision because of the two views, you can't ADS with two eyes and you can't aim between the two views with one eye/view. As far as alternate input methods go a Wii Remote using GlovePie and just aiming from the wrist works fairly decent, as does the Razer Hydra ... and as far as precise couch potato control goes my favorite so far is a PS Nav controller with a wireless Logitech trackball.
