Microsoft plans to offer devices based on Perceptive Pixel technology that uses both pen and touch to create what is equivalent to the human as the user interface.

The Teslatouch technology is based on the electrovibration principle, which can programmatically vary the friction between sliding fingers and a touch surface - and provides a wide range of tactile feedback sensations to fingers moving across a touch surface. When combined with an interactive display and touch input, it enables the design of a wide variety of interfaces that allow the user to feel virtual elements through touch.
