HCI Book Chapter Wearable Computers

Computers have become a primary tool for office workers, allowing them to access the information they need to perform their jobs; however, accessing information is more difficult for more mobile users. With current computer interfaces, the user must focus both physically and mentally on the computing device instead of the environs. In a mobile environment, such interfaces may interfere with the user's primary task. However, many mobile tasks could benefit from computer support. Our focus is the design of wearable computers that augment, instead of interfere, with the user's tasks. Carnegie Mellon University's VuMan 3 project provides an example of how the introduction of wearable computing to a task can reap many rewards.
