New Touchscreen Technology Allows Users to Feel Buttons on Screen
Researchers from Carnegie Mellon University have created touchscreen devices that use embedded electroosmotic pumps to create pop-up buttons that can be felt by fingers. The technology, called Flat Panel Haptics, can create buttons measuring almost five millimeters in height with enough pressure and rigidity to make them feel solid when pressed. The limitations of the technology include pre-determined shape and size of the pop-up buttons, but eventually, any size and shape of tactile button could be generated on-demand.
