Introduction

Computing is increasingly intertwined with our physical world. From smart watches to connected cars, to the Internet of Things and 3D printing, the trend toward combining digital and analog materials in design is no longer an exception, but a hallmark for where interaction design is going in general. Computational processing increasingly involves physical materials, computing is increasingly manifested and expressed in physical form, and interaction with these new forms of computing is increasingly mediated via physical materials. Interaction design is therefore increasingly a material concern. Welcome to a book on the materiality of interaction, and material-centered interaction design!
