A longstanding goal of engineering has been to realize haptic interfaces that can convey realistic sensations of touch, comparable to signals presented via visual or audio displays. Today, this ideal remains far from realization, due to the difficulty of characterizing and electronically reproducing the complex and dynamic tactile signals that are produced during even the simplest touch interactions. This book presentsmethods to capturewhole-hand tactile signals produced during natural interactions, characterize the information content in these signals, and use the results to guide the design of new electronic devices for tactile feedback.
