| A BYOAC Lightgun, are we up to it? |

btw, as another way... there are some very cheap crappy guns that work in mame. Whats the chance if we hacked them into a true arcade gun, and the arcade guns original optics... that it would be better then the original? It might make sense to use either the bio gun or the other crappy but kinda working still selling guns and fit them in a better case... with better optics. might be an option. |

I graduated with Honors from High Tech Institute, a trade school in Phoenix, AZ and currently have my Associate degree in Computer/Electronics, FCC GROL Certification, C.E.T. certification, Fiber Optic Certification, and my A+ Certification. I currently work for Agilent Technologies in Santa Rosa, CA. VR is one of my passions. My first Virtual Encounter was enough to hook me on this amazing concept. I have surfed the web countless hours looking for everything from Power glove information to old Vr Systems that never where, like Atari's IVR system. I am going to update my page as much as possible with all the information I have found on any subject regarding Virtual Reality and so forth. If you ever have any questions or comments please feel free to email me. I have much more info then listed here and I am always happy to help. So here goes. --- End quote --- |

I think the camera gun is not going to pan out. A cheap USB camera just doesn't have the resolution to get the accuracy you can get with a proper light gun. I'd be willing to bet that motion tracking on two guns simultaneously will bring any system to its knees. What you're doing is trading screen flash for precision. There is a better compromise: rather than reinventing the wheel, improve on it. The screen flash on most PC guns is usually pure white, which not only gives you a headache pretty quick, but also distorts the monitor, further degrading accuracy. A better way would be similar to the Guncon 2/PS2: flash the screen gray. Easier on the eyes, less distortion, and still enough contrast for the gun to time the flash. I think by far the best thing would be to use existing hardware as much as possible. I think by the time you buy a gun to gut it, and a camera to hack inside, you'd actually be better off buying a Happs gun (the basic model is $70 in standard colors, and it even fits their holsters.) If someone could come up with a cheaper interface for these, and a Mame driver, you'd be on to something good. Speaking of which, I am working with Jack over at R0R3 to get one of his boards for testing, and a couple recoil guns on the way from Happ. If someone wants to work with me on creating a Mame driver, speak up now... BTW, in the absence of the Act Labs VGA guns, there are always these: http://www.lik-sang.com/info.php?category=270&products_id=1429&PHPSESSID=6ab3f4545866b56802e980b3c167ccda I've found them to be decent when properly calibrated (video must be 640x480, and need to tweak mouse sensitivity settings a bit), and two will work with Analog+. Out of stock currently, but hopefully they'll be back. |

i agree that motion tracking of cameras is not the most effecient way to go about this. I also have my doubts about just improving the video-gun idea. If we can get a good solid gun a la guncon2 then great, but to work with composite/s-video/and PC's would be rather akward, increasing the work. Plus plahying around with my really old monitor I find that globally increasing the brightness - even just to light gray - has a rather large distortion effect. I'm convinced this would affect the accuracy. If we are starting from scratch, I say go for the prefect solution - remove the display from teh equation altogether, 1-off calibration at installation, real-time tracking. Aim high! |

Well, a 1mega pixil camera with propper lenses would probably be more accurate than an arcade lightgun. However... many cameras lack the speed needed for such a fast realtime situation. The bandwidth would be insane, and again, something would have to interpret the images in realtime. Also, a typical lightgun may not work for many different types of displays. A typical arcade machine is spec'd out to precise means: 1) Known arcade monitor, refresh rates, ect. 2) Perfect sync arcade system. A pc running windows isnt the most stable thing as far as 'timing' goes. Windows itself may use methods which throw timings off. Special video card drviers may update displays in odd ways or timings as well. Some tvs use strange updating methods too - which is why my panasonic tv wouldnt work with the act-labs tv gun. Im no expert on this kind of hardware... but from the things Ive seen, Im pretty sure that a typical arcade lightgun will not function well with mame and a non arcade monitor. An alternative method is needed... or should be sought. However... it may well be beyond the expertise on this board. Or, at least - maybe beyond the financial capability. |
