The Tesla Touch Allows Users to “Feel” Virtual Textures
Normal touchscreen devices operate by passing just a small bit of current through the users finger or stylus…which is why you can’t work your fancy smartphone with your mittens on, or when your hands are particularly cold.
But the Teslatouch uses “an electrostatic force [that] physically attracts the finger (almost like a magnet) to the interactive surface. Additionally, the input signal is uniformly propagated across the touch surface; therefore, the resulting tactile sensation is spatially uniform.”
I’m not entirely sure what all of that means, but this video that shows it in action is completely awesome:
