Might be a crazy idea, but download the demo from
www.mousevision.com and try it out with any old webcam. It basically tracks a point and uses it to move the cursor. Now, before you scream, give it a try because:
* It seems to be stunningly accurate at just tracking your head, especially when you tweak the settings. I was able to write my name in MSPaint just using my head!!!!
* It is apparently even more accurate when it has a fixed white block to track
* It has a mode for tracking a bright object, e.g. an LED
* It works even if the camera is not straight-on
* At approximately $20 it ain't expensive, and there is a free 30 day demo
So, in theory, you could use a gun with a white solid tip, or even a reflecting tip, and a fire button wired up. The control would just replace the mouse, so no flashing screens. I'm going to give it a whirl myself.
Presumably you could use it in conjunction with a traditional light-gun using AnalogMame+ for two simultaneous players?
Has anyone tried using this program as a gun?
