Tactile Rendering of 3D Features on Touch Surfaces

Tactile touchscreen developed by researchers at Disney

Researchers at Disney have developed a way for people to “feel” images on a touchscreen using electro-vibration.  Dr Ali Israr and colleagues at Disney’s research lab in Pittsburgh have made this possible through a vibrational technique which re-creates what happens when a finger tip passes over a real bump.  The algorithm is described in detail in the video on this page.
