To provide input and control, wearable computer solutions must replace the familiar desktop interface devices of keyboard and mouse with specialized hardware. While successful wearable input solutions have been developed for domain specific applications, a standard input interface for general purpose wearable computing has yet to emerge. The steep learning curves and unruly hardware of the solutions proposed thus far are one of the factors keeping wearable computing out of the mainstream. This thesis proposes a new input and control approach that increases wearable computing usability by integrating several commonly available devices into a comprehensive system. The proposed system integrates commercial, off the shelf hardware together with generalized software applications that increase the usability and general utility of a wearable computer. The hardware consists of a wearable computer, a clip-on microdisplay eyepiece and a standard PDA running Pocket PC. Through a Bluetooth network, the PDA can wirelessly control the text input (keyboard) and pointer control (mouse) of the wearable computer. The software consists of two applications designed to provide easy access to new content and previously stored data. One application presents a user with a continuous scroll of new content which can be attended to at the user's discretion. The content is dynamically retrieved from any online sources, and can range from news feeds and stock quotes to calendars and weather reports. New content can be added to the user's persistent digital store at any time. The second application, a private peer-to-peer data sharing program called the Tangle, was developed to fuse the user's multiple data sources (home or work computer, wearable computer, PDA) into a single, searchable repository. Tangle also provides easy access to the digital assets of other, trusted Tangle users. Tangle makes it easy for virtually any content that a user encounters while using the system to be easily added to the user's persistent data store.
