Abstract: As ubiquitous computing becomes more prevalent, greater consideration will have to be taken on how devices interrupt us and vie for our attention. This paper describes Auramirror, an interactive art piece that raises questions of how computers use our attention. By measuring attention and visualizing the results for the audience in real-time, Auramirror brings the subject matter to the forefront of the audience's consideration. Finally, some ways of using the Auramirror system to help in the design of attention sensitive devices are discussed.
