LCD TopGun Hands On Review
Xbox Evolution writes "Lik Sang has done a hands on review of a lightgun that is compatible with Plasma, LCD, TFT & DLP. The review of the LCD TopGun which works with the PS2, Xbox and PC gives a good overview of the features and functionality."
Don't click. I've seen this URL before.
Probably not safe for work.
Wikipedia has the answer.
They detected the bright pulse of light caused by the electron beam hitting a parituclar phosphor. This swept across a CRT pixel by pixel, line by line. This only works with a CRT and needs specific support from the graphics hardware (to find out the X/Y position of the electron beam at the time of the light pulse)
This doesn't work with LCDs, Plasma TVs, DLP/LCD projectors / OLED displays etc. as all pixels are illuminated simultaneously, not sequentially.
Don't light guns use intensity and not position to determine if you've hit the target or not? Why would they need to be "compatible" with a display device if all they depend on is intensity?
Traditional light guns for CRTs since the Super Scope use submicrosecond timing of blue and green phosphor flicker, which when correlated with the timing of the horizontal and vertical blanking of the composite or luminance video signal gives position. Even older light guns that rely on intensity, such as the Zapper, might get confused by LCD's slower response and lack of flicker. This Wikipedia article should help you understand.
Actually, it looks nothing at all like a Glock. It seems to me to be modeled after the Beretta 92F/FS.
http://www.erealgames.com/ I find this gun heaps more promising although there isn't any PC support yet. Works with PS2 and X-Box's though.
