Augmented and virtual reality often focus on extending the human-computer interface through sophisticated 3D graphics. However, while graphics have had a significant impact on the computing world, the written word still dominates computer use. In general, 95% of human-computer time is spent word processing. Through the augmented environment made available by wearable computers, word processing can occur almost anywhere. With the heads-up display, the computer has the ability to display messages unobtrusively or urgently grab the user's attention. In addition, the wearable computer can display text or graphics in physically meaningful locations in the visual field, provided that it is aware of where the user is looking. Using these concepts, word processing can be significantly enhanced with a sort of augmented memory. In the system described below, a one-handed chording keyboard is used for entering text (see Section 5), though the system can be adapted easily for those instances in which speech recognition is appropriate.
