Can anyone tell me if it is possible to use an existing capacative or resistive touchscreen(ie an iphone) through a sheet of glass or other clear substance. If the glass etc is layed directly on top of the existing touchscreen what does the touchscreen "sense" through that glass etc. Is it electrical or motion sensed.
Thanks

A capacitive touch screen *may* work, sometimes they can surprise you but it really depends on the specific model you have. A resistive screen will not work. You could lay a resistive element on top of the glass but taking an existing solution and doing as you mention cannot work. Capactive screens can work behind materials while resistive screen can't. Capactive screens can support multitouch whereas restive screens to my knowledge can't.
