Introduction

How will we interact with our computational environments in the next 10 years? If the past is to be any indication of the future, our hands will remain restricted to a keyboard and our eyes will remain focused on a desktop display. It is true that progress in mobile computing, computer networks, and miniaturization allows users to access information through a number of less restrictive devices (e.g. video capture and playback on a cellphone). However, these devices really represent the same metaphor of interaction as the traditional desktop computer -- the keyboards and monitors are smaller, but they still sit between us the computational environments we access.
