Unlike other touchscreens, this electrovibration-based display from Disney Research uses a new algorithm developed in-house to allow the human hand to feel the textures of objects as presented on the screen. It maps the frictional forces between the screen and the user’s finger to the surface contours of the virtual 3D image presented on the touchscreen.

This dynamic allows the system to adjust to various virtual surface sensations on the fly, rather than offering canned sensations as some tactile touchscreen feedback experiments have demonstrated in the past.
