I'm trying to fabricate a touchscreen out of my 22" LCD screen using a method similar to Johnny Lee's WiiMote Whiteboard, except I'll be using a webcam since I don't have a Wii or a Wiimote or a BlueTooth adapter.
The infrared pen I've made will be activated by either putting pressure on the tip of the pen (such as touching it to the screen) or by pushing a button I've put on it. I like touching it to the screen better, but I'm not sure if it will put scratches on my glossy screen. The monitor is a Gateway HD2200, BTW, if that affects anything.
So, does anyone know if the tip of an LED (
this one, to be exact) would scratch or harm the surface of an LCD monitor?
Thanx,
Brijar!!!
