Went digging through the guys youtube page and eventually found a comment where he linked to this: https://item.taobao.com/item.htm?spm=a230r.1.14.40.ebb2eb2BpVsM2&id=547838903438&ns=1&abbucket=19#detail The text in the description is all images, so if somebody with better google fu than me wants to figure out what it says then have at it. It looks to me though like they are selling a hacked gun and a ps eye camera for 200 bucks. If the driver is somewhere in that mess of links we have a ready made solution. |

I got this cool website which is able to translate chinese from pictures: https://translate.yandex.com/ocr Worked well by saving images and selecting the files with yandex It's basically advertising, with some interresting text in the end : --- Quote ---Suitable for people: there is a basic operation of the computer (download and install the computer software ) The Light Gun Game love the good guys . Composition of electroencephalogram light gun : Game light gun + wireless receiver + PS3 camera + positioning software computer light gun principle : The game light gun emits laser light onto the display, and the computer uses the PSS camera to shoot the video on the display Light spot, calculate its position on the display, and control the mouse to its position. The game light gun uses wireless transmission of its key information to the computer . --- End quote --- --- Quote ---The advantage of a computer light gun : High positioning accuracy, after calibration mouse cursor and laser spot deviation can be controlled to 20 pixels or less 2. No accumulation of deviation, how long the game will not produce mouse cursor and laser spot accumulation deviation 3. Fast response, PS3 camera 75HzFPS, has exceeded the normal LCD screen 60Hz refresh rate Simple debugging, application of fast Matrix conversion of image processing algorithms, 4: 00 calibration light gun positioning 5. The use of N system standard high-speed PS3 camera, light gun game and video chat Entertainment two phase should 6. Light gun model fine level high, appearance, clear texture, good sense of hand, full grip --- End quote --- And then there is the big list of links, with sample videos and files to download. There are a lot of emulator binaries and game patch (I still didn't find out how to really download the files from this crappy chinese cloud though) And PSEyes drivers but you can find that anywhere else They are mentionning some other software(in RED !) : --- Quote ---The copyright of the computer light gun positioning software is owned by XuHai personally. It is used by computer light guns and is continuously updated. If you have purchased a computer light gun, please contact customer service to obtain the "Computer Light Gun Setup Tutorial". --- End quote --- So at the end, and because of what is written in the last part, I think they are providing in this list all modified exe/emulators to play with absolute coordinate instead of Windows' relative mouse positionning : --- Quote ---Computer Light Gun Game patch support : PS1 emulator ePSXe original program is to use the relative displacement of the shop has been a unique release absolutely A light gun version of the main program, to match the shop computer light gun use. Perfect support " solution crisis 》 And " chemical solutions crisis machine taitan plan ". PS2 emulator pcsx2 the original program is to use the relative displacement of the shop has been a unique release of absolute The main program to match our computer light gun use. Perfect support " solution crisis Machine 2》 , "Chemical solution crisis Machine 3", " chemical solution crisis machine hazard zone 》、 "VR", " Ninja sudden "Attack", "vampire night"."Battle Fire Fly: AFU Khan" and " Battle Fire Fly: broken Spear " the original program is to use the relative displacement, the shop has been alone to publish the absolute positioning light gun version The main program to support the use of our computer light gun. "Rambo game" is the use of the original program of the relative displacement, the shop has a unique release of absolute A light gun version of the main program, to match the shop computer light gun use. --- End quote --- But I found no evidence of any driver or interesting thing like that :-\ |

Very, very useful thanks. So it sounds like this is a homebrew solution as I thought since something like this would have been made available in the states if an actual company had released it in traditional markets. You know when adapted to US dollars it's only around 25 bucks. I figure it would be a nightmare to get imported though. Technically I can write a piece of software to scan webcam stills to detect motion, but I have no clue how to optimize that, so it'd probably be terribly slow. Since wiimotes do all the heavy lifting with dot that might still be the way to go. That being said there are webcam motion tracking software suites out there that might also get the job done. |

I did some testing and man, maybe the wiimote isn't the way to go. Put a sensor bar in front of my cab and put the wiimote at the very edge of the control panel (about two feet away). Couldn't see the four corners of the 27 inch screen.... wasn't even close. I'm not sure about what kind of lens to get either. The only way I could see the wiimote working as-is would be if it's mounted from the ceiling a few feet back. The added height would increase the distance and that might barely be enough for medium sized monitors. As for the ir laser, what about the lasers used in some laser tag sets? I'm not sure if they use ir lasers or just an ir light. We really need someone to chime in that has experience in optics. Lens filters could really make things easier if we knew what we were doing. |

Sorry for the multiple replies... I can't sleep again tonight. Checked out some of those old wii whiteboard posts from back in the day. It looks like it's difficult to find an ir laser that will register with a wiimote. https://www.wiimoteproject.com/wiimote-whiteboard/ir-laser/15/ One of the solutions mentioned on page two is to simply remove the ir filter so visible light can also be used. This could be combined with gel filters and multiple wiimotes to have, for example, one gun use a red laser and one use a green. I'm wondering if the ir lasers will then work without the filter though.... Personally I would like to have an invisible laser. I also looked at Johnny Lee's old whiteboard video. He seems to be able to see the whole screen with the wiimotes fairly close, so perhaps my aim is just off. He does mention that the wiimote can only see about 45 degrees in either direction. I've got an old generic wiimote I got for 3 bucks that I don't care about. I might try removing the filter and/or adjusting the lens tomorrow night. |
