Lucas123 writes "Engineers at Disney Research in Pittsburgh have developed an algorithm that creates the illusion of a 3D surface on touch screens. Using electrical impulses, the touch screen technology offers the sensation of ridges, edges, protrusions and bumps and any combination of those textures. While Disney is not alone in developing tactile response touchscreens, its researchers said the traditional approach has been to use a library of 'canned effects,' that are played back when someone touches a screen. Disney's algorithm doesn't just playback one or two responses, but it offers a set of controls that make it possible to tune tactile effects to a specific visual artifact on the fly. 'Our algorithm is concise, light and easily applicable on static images and video streams,' the researchers stated." This summer Disney unveiled AIREAL, a system designed to give tactile sensations to people using motion control devices.
