An evaluation of audio-centric CMU wearable computers

Carnegie Mellonʹs Wearable Computers project is defining the future for not only computing technologies but also for the use of computers in daily activities. Fifteen generations of CMUʹs wearable computers are evolutionary steps in the quest for new ways to improve and augment the integration of information in the mobile environment. The complexity of their architectures has increased by a factor of over 200, and the complexity of the applications has also increased significantly. In this paper, we provide a taxonomy of their capabilities and evaluate the performance of audio-centric CMU wearable computers.
