XM Satellite Radio is taking a different approach to the touch-screen/gadget craze. They have a patent on a gadget whose functions are mapped out to your fingers instead of its screen. Wanna switch stations, use your middle finger. Wanna access the menu, use your index finger. The technology would rely on your fingerprints to work and XM claims it'll make navigating through channels easier.
Personally, something like this would confuse the hell outta me and unless this is a gadget that I use everyday, it'll probably have a steep learning curve too. No word on when we'll see any of these new touch-screen gadgets.
