Imagine a screen that could tell the difference between the fingers you use to touch a screen. You could do different stuff with each finger (drawing, left-click, right-click, selecting text). If a friend touches you screen it would draw in a different color, or not work at all, thereby rendering all passwords useless, as when you touch you fingerprint is instantly recognized. A laptop would be just a screen, no moving parts, just the touch screen. We would have a fresh new look computer, and awesome computer games, and a total new user interface.-- IceFest, Nov 24 2007 What if you cut your finger? And do the ends of my thumbs have a recognizable fingerprint?-- MisterQED, Nov 24 2007 We have 10 fingers, if one gets cut the database gets corrected, police can use parts of fingerprints so it should work .-- IceFest, Nov 24 2007 I don't belive so. Still, the idea is good. And, with a really good processor, it might work. Granted, it would have some lag, but that can be fixed in the next few years.-- Shadow Phoenix, Nov 24 2007 Seven years later, this might actually be happening....-- IceFest, Mar 01 2014 random, halfbakery
