Tanvas lets you feel your touchscreen
Tanvas Touch is indeed one of the striking innovations that were displayed at CES 2017.
Offering new surface haptics, Tanvas lets you feel different materials, like silk, cotton or even grass, on the touchscreen of your tablet.
The ordinary haptic feedback, which smartphones use to help make typing on a touchscreen is being modified by TanvasTouch technology after extensive research at Northwestern University to allow you to scroll your finger across your iPad and feel difference between corduroy and silk.

Tanvas, which is a product of a decade of research by Ed Colegate and Michael Peshkin, uses electrostatics to modulate friction for its technology.
