Summary

This book introduces methodologies to develop a variety of wearable interfacessmall body-worn intelligent machines that are always with the user and are designed to be useful in mobile settings. The authors address the development of these intelligent caps, glasses, shoes, finger rings, etc., as mobile devices for control, communication, and recognition and discuss the technologies associated with them, such as architecture, learning, and real-life applications.
