A BYOAC Lightgun, are we up to it?

From the gun design stand point several things have to be considered. it should be no heavier than the act labs gun--anyone who has actually played a game of area 51 knows that after 10mins, your arms are killing you and that thing weighs mere ounces. Also, would an accurate sighting mechanism be possible. This would make eventual calibration even more precise.

Also the length of the cables should be longer than an act-labs standard length so that the control box (if required) doesn't have to be at the front center of the cabinet. wireless would be the cats --I'm attempting to get by the auto-censor and should be beaten after I re-read the rules-- but that seems a tad more difficult.

Have any of you looked at the videos on the HandVu page?

Tracking a few LED's would be a lot easier than what they have done, and they don't appear to be using anything really high end. The minimum cpu they reccomend is 1.5ghz.

It looks like a good start if you want the gun to work on all monitors.

The big problem with the Gyro mouse/Gun idea is that there is no relationship between the gun and the screen at all. You can stand anywhere with in range of the receiver and the mouse will still work. You could stand behind your cab and it will still work! You would not be aim with the gun. Others have said that you have to aim by twisting your wrist instead of moving your arm to mae these work. This is not the most natural motion for using a gun.

I wouldn't fancy running mame on my pc alongside an app that has a minimum cpu requirement of 1.5GHz, and then streaming 60fps video down the USB port.

Well 90% of the cpu load they are doing is tracking the hand and trying to figure out how the fingers are held in realtime. This would be tracking a single point of light, or even better a target pattern on the end of the barrel, that is static and never changes shape.

I don't think you would need 60fps of full resolution video either. You should be able to track the gun accurately enough in a 320x200 mode, or maybe even 160x100 black and white at fairly low fps, just enough to show you a cursor updated a couple of times a second, then when you pull the trigger it could then take a high resolution shot to get exact location of gun.

I was playing with the nose mouse project with a $40 usb 2.0 camera I picked up at officemax yesterday, and it worked suprisingly well for playing arkanoid and tetris, a little tiring though.
