We found out that that the 55" rear projection CRT 1080i TV we had in college worked with light gun games. Fun times. That thing was HEAVY.
CRTs have their place and will forever, but the size just ruined it for them. Same with plasma being so heavy and hot.
Yup, and I have been missing light gun games the last several years!
There are 2 techs that work on the new TVs. The most common uses IR sensors or cameras. One of these has an IR bar at the TV and is the same fundamental tech as a Wiimote. The other uses a camera that sees the TV screen, and the blasters shoot an IR beam at the screen. The disadvantages of these are that you need the extra peripheral device, and if you move positions during play or pass the gun to the next player, then you have to recalibrate the gun each time.
The newest tech, the camera is in the lightgun itself, and the required software adds a thin white border around the playfield image. The camera uses an algorithm based on the white border image to aim accurately. The advantage of this is that you don't have to recalibrate when you change player positions. But, this one is still on Indiegogo. I placed my order at the beginning of Feb, and expect to have my product at the end of March. But, many batches of product have gone out, and the tech is legit.
