what the hell is a lightpen?
Has anyone used a lightpen as an alternative to a touchscreen?
Opinions and thoughts are welcome
This is 70's technology which is probably why you don't know about it but it looks like it might work just as well. Remember the old Nintendo gun that you played Duck Hunt with? Same technology. It's basically a light that senses your position on any screen. Anyone know where to buy them and how much they go for?

No frickin way! A couple years ago I removed an threw away hundreds of them that were attached to terminals in the hospital I worked for. We replaced them with WindowsNT workstations.
Why? Aside from the obvious limitations of a dumb terminal, the parts were increasingly hard to come by and very expensive. Light pen = $300+; Mouse = $10. You do the math.
Since touch screens kits are cheaper and easier to use, why bother with a light pen?

They would only work with crt displays anyway. The technology are similar to a Playstation gun and stuff like that. It is a sensor that reads when the light of the screen passes. (which it obvious doesnt on a lcd screen). Havent seen it (cheap) for pc's since the freq and the resolution of the monitor varies and you would have to recalibrate all the time to fit the screen. The cheap guns for playstations wont even work on a 100 Hz tv.
