Touch-screen interface that lets you "feel" objects

We perceive variations in an object’s surface by detecting changes in friction on our fingertips. The interface simulates these variations through a series of low voltage electric currents that cause vibrations in your fingertips. In its most basic form, the system involves an insulated electrode paired with an electronic driver to create the voltage patterns.

Researchers at Disney are working on a touchscreen interface that lets user "feel" objects. The interface allows you to feel properties of objects, for example bumps, ridges, textures, and protrusions.



Additionally, Disney research is also working on using air cannons to simulate touching digital objects: http://www.wired.com/design/2013/07/disneys-tiny-amazing-air-cannons-will-let-you-feel-the-digital-world/
