Abstract :
Walking with a wearable computer should be more like driving a car. With a car, much of the attention is dedicated to the environment around you: looking for pedestrians, watching for stop signs, and staying in your lane. Occasionally, when everything looks clear, you might look at the speedometer, fuel gauge, or radio station displayed on the dashboard. These displays are arranged and designed so that you can monitor the car´s state with a glance. Yet the displays don´t intrude-the author determines when and how often he looks at them. He manages his own attention.
