Disney researchers are developing technology that allows you to feel textures on a touch screen that may help visually impaired people.

Electrovibration can be used to create electrostatic forces which then create friction against the finger creating that touch sensation.

The other half of this exciting development is a unique algorithm the Disney research team developed which generates these frictional forces dependent upon whatever is on any given screen. They have created an algorithm which will show stairs as a series of rigid steps whilst a ball would have a gradually curving surface.
