Shape-Shifting Touchscreen
Microsoft wants your touchscreen to touch you back. It recently published a patent, filed in 2009, that describes a touch screen in which you can feel texture and shape, making you feel like you’re actually touching an object even when you’re not.
Ultraviolet wavelengths beneath the screen’s pixels control the shapes that the polymer coating on top of the screen makes, enabling you to feel images, interfaces, or a virtual keyboard.
