Wearable computers: no longer science fiction

By using devices carried on the body, wearable computers allow the exploration of the principles of pervasive computing immediately instead of waiting for the deployment of the ubiquitous infrastructure often associated with the field. However, wearable computers are often misunderstood, both in their research and application. I've been wearing a computer as part of my daily life since 1993, and in this article, I explore the attributes that make wearable computers a unique approach to ubiquitous computing and discuss current topics in the wearable computing field.
