Abstract

The paper describes a system level design approach to thewearable computers project at Carnegie Mellon University (CMU). Theproject is an unique example of a cross-disciplinary effort, drawingstudents from mechanical engineering, electrical and computerengineering, computer science, and industrial design. Over the lastsix and half years that the course has been taught, teams ofundergraduate and graduate students have designed and fabricatedsixteen new generations of wearable computers, using an evolvingartifact-specific, multidisciplinary design methodology. Thecomplexity of their architectures has increased by a factor of over200, and the complexity of the application has also increasedsignificantly. We introduce a metric to compare wearable computersand show that their performances have increased by several orders ofmagnitude. A system-level approach to power/performance optimizationis going to be a crucial catalyst for making wearable computers aneveryday tool for the general public.
