Just got to thinking about something???

I was thinking about the lightguns for my old NES. How does the gun work? Does it work like the wii motes? And if so...why no sensor bar? Can someone compaire and differentuate these 2 technologies for me??

If I am correct in my understanding of the old style light guns they work like this:

Old TV has a cathode ray tube, this effectively emits a steam of particles that hits the screen and is then turned into a coloured pixel. That stream then scans across and down giving you the old resolution of a TV.

The light gun game makes the screen flash and the gun attempts to capture the location of the beam at the point of the screen it is pointed at.

-----

The Wii-mote sensor bar has two IR emitors that give out signals. The wii-mote receives these signals and calculates the point of the screen it is pointing at based on the delay in receiving each of the IR signals and the motion sensor in the wii-mote itself.

Very different technologies.

When you pull the trigger on the NES zapper, the game puts a white square on the board over the target, for a split second. If the zapper can see the white square, meaning you were aiming at the target, it tells the NES that you hit the target.

The Wii sensor bar has the two infrared LEDs in it. The Wii remote has a camera in it that can see the LEDs. The camera generates a little picture that's all black except for the LEDs which show up as white dots. You can see what the remote sees when you go to the Wii's calibration settings. The Wii takes the X,Y positions of the dots, and your calibration settings, and uses math to put a crosshair on the TV. When you move the remote around, the little picture changes, and the Wii uses the new position of the dots to move the crosshair.

when playing on those TVs, dont stay too close to the TV, unless you like X-ray radiations. about 30cm (1ft) is enough. yes there are people that play that close... i wonder how they're still not blind

[QUOTE="BrunoBRS"] i know this is OT, but just a warning:

[QUOTE="BrunoBRS"][QUOTE="aransom"]Do you have a source for that? I'm a bit skeptical that TV sets are a source of X-ray radiation, and even if they were, I think you'd get almost as much dose ten feet away from the X-ray emitter, as you'd get from one foot away.
