FingerFlux Touchscreen Harnesses Magnets For Physical Feedback
"Just below the surface of their prototype interactive table sits an array of tiny electromagnets whose strength and polarization can be individually controlled. In its current form the system requires users to wear a magnet on their finger, like a small thimble, but that minor inconvenience facilitates some unique methods of interaction. One of the biggest issues with touchscreen interfaces is that you often need your eyes to guide your finger to a button. But the FingerFlux system could blindly guide a user’s finger to a specific part of the screen by generating strategically placed attractive and repulsive magnetic forces."
