Summary
Smartphones have strong video and audio capabilities. However, they are less capable when it comes to providing touch (haptic) feedback, which is limited to simple things like vibrating or simulating keyboard clicks. How to recreate the haptic richness of everyday objects, such as rubbing a cotton shirt or feeling a fine wood finish in furniture, is an open problem in building better user interfaces for phones and other devices. This project will develop methods to provide richer haptic feedback by engineering textures at multiple scales, ranging in size from microscopic to visible to the nake
