It won't work, the LEDs need to be far enough apart to use them in any kind of calculation. The ps move was doing that only because it had tons of other sensors in it. Even if it worked it would need to have at least twice the number of arduinos, a software to combine their both input into one (if that's even possible) and would be a pain to use in multiplayer. But of course you are welcome to try to build a system like that, people were saying 4 LEDs system were unluckily to work, and I still made it, so who knows 🤣 |

How do they manage it with arcade IR guns which have 10 - 12 led sensor boards positioned around the screen bezel? The House of the dead 4 arcade has been dumped for use with Teknoparrot. perhaps there is some code ideas to borrow given that the PCB is basically a regular PC? The arcade IR guns I have used seem to be a lot less sensitive to changes in the players position and they seem slightly more accurate (than an Aimtrak). I assumed this was due to them using 10 led clusters instead of 2. |

I assumed this was due to them using 10 led clusters instead of 2. --- End quote --- From my understanding, those arcade gun systems use a wide angle/high speed IR camera, and I believe they either make the surrounding leds flash one by one really fast, to make the camera know which is which, or they have a very good algorithm to keep track of them all without having to make them blink. There is an arcade center close to my place that has it, next time I go there I will try filming the leds at 240fps to see if they blink. The limitation of our current setup is that the camera has reduced framerate (not fast enough for blinking), can only see 4 IR points at a time (not enough to have this 10+ led setup), and has a low viewing angle (23~33 degrees). But the good news is that I still manage to make a very similar system with 4 leds! Like in the arcade it has auto calibration that allow you to have perfect accuracy no matter your position, and reduces the minimum distance requirement greatly. You can see it here: http://forum.arcadecontrols.com/index.php/topic,161189.0.html I just finished the first version of it, I will post it soon for whoever wants to try it. |

I keep meaning to try one of those Extreme IR sensor bars made for Aimtraks to see if it delivers the wide angles it promises and the improved accuracy. They apparently can be seen (by the gun) from 140 degrees and work much closer to the screen. The arcade guns definitely have nicer looking cameras with noticeably larger lenses. The difference between Raw Thrills gun camera's like this and an Aimtrak camera are night and day: https://na.suzohapp.com/products/arcade_game_parts/820-00010-01 With that said, the guncon 3 works about as well as the Time Crisis 4 arcade gun in terms of accuracy. It's just irritating in how it loses sight when you get within 8 feet of the screen. If that can be solved with better led boards, I'd take it over an Aimtrak. I'd never give up my real light guns on a crt though. |

It's especially annoying when you want to play with a friend that love arcade gun games but don't understand anything to this calibration thing. I'm still searching better solutions for those damn IR led. Even very powerful ones don't work perfect. I'm investigating with SMD leds, since they seem to have way better power and angle. |
