The Feedforward Torch

Abstract

An important challenge in deploying pervasive computing environments is the di culty users have in understanding their behaviour. It has been suggested that these environ- ments should be made intelligible by informing users about their understanding of the world. We propose the \Feed- forward Torch", a technique that combines a mobile phone with a pico projector to help users in an pervasive comput- ing environment understand what the result of their actions will be.
