I doubt I can get a software solution to fake dual mice because of the way dual mice work, but I can probably get them to show up as joysticks.

Glossy screens might be fixed via "clear" contact paper. I checked and yes, such a thing exists. Multiple players might mean two cameras with a different light filter on each and lasers putting out different ends of the spectrum.

What I meant was not the software side of things, but rather the hardware. How do you separate 2 laser pointers and determine which one is player 1, and which one is player 2. With 4 players this would get messy. Also, if your camera is not accurate enough, it would be a problem if both players shoot at the same screen position. I wonder if one could do something with a simple lens, like in those laser levels, where you get a line instead of a dot. with 2 ir lines , it would be easier to separate 2 guns from eachother.

Like I said, you use lasers on opposite ends of the spectrum. One IR and another UV. The camera setup for IR can't see the UV dot and vice versa. It could be done with visible lasers as well assuming you don't mind the dot. You can do shape processing but it's better not to. Finding a dot in a picture is pretty quick ... determining what shape it is isn't. Another option is having an Arduino control the on-off of the lasers and have it strobe the lasers in sequence, reading one at a time. I'm not sure how quickly lasers fire up and fade off though, so that might not work.

There aren't any 4 player light gun games that I'm aware of... there are some three player positional gun games.

2 ends of the spectrum would probably work, requiring 2 cameras nowadays wouldn`t even be that much of a problem.
Maybe one could simply take two ir lasers, and make one much brighter than the other one.

Another approach (that just came to my mind):
We could use identical lasers, that are pulsed at 120 hz, and get some cheap 3d shutter glasses (10 usd) for the 2 cameras) then we would have to sync the framerate to the cameras ( or probably [most likely)] that isn`t needed) - sync the guns to the glasses, and let them pulse with 120 hz ( microcontroller), with one gun always being on and the other one always being off. this should give (in theory) a somewhat robust, working solution, with 2 same laser pointers.

So the Mars PDP is for Xbox, delayed and no mention of aPC version. Blech. I do have a couple of ps3 eye cameras. Tried to use them with the ShootOff software but they locked up all the time. Hopefully they work better with different software.

Howard_Casto:
No the pc version is up on amazon as well. It's a two gun kit for $129. I'm not sure if there is a single person kit or not, but honestly the base unit is $99 anyway so it'd be silly not to fork over another 30 to make it two player.

This one has actual completed product shots and pre-orders on amazon via a well established hardware company so atm at least it's closer to production than the sinden guns. I want to see them both come out so people have options, but dems the facts.

The software example I found really works with any webcam, but the high frame rate of the ps eye is something unusual on a low end, low resolution camera and processing a smaller image obviously takes less time, so I figured that'd be the place to start. I think 640x480 should be enough, but like I mentioned in other threads, I'm not 100% certain it's enough in oddball mounting situations where the view wouldn't be straight on.

here's a hack for opentrack

it's work with only 1 point but for IR , i test it with PS3 EYETOY it's works but like a LIGHTPEN ( can't move with angle )
another hack of this for laser could work like a charm
