New Scientist has a report on a “see through” touch screen that solves the problem of fingers obscuring the view of the screen during use. This seems to be a helpful and useful addition to small touch screens like on cell-phones, game systems, cameras and PDA’s. Of course, larger touch screens like Kiosks have less of a problem with obscuring view so this technology would not be appropriate. (You don’t usually hold the back of the screen on a kiosk.)

Electronic devices have been shrinking for years, but you might be forgiven for thinking that one that’s only a centimetre across would be just too difficult to operate.

Now tests of a prototype device only slightly larger than this have shown that it can be made perfectly usable by combining a screen on the front with a touch-sensitive pad on the back. Read more…
