It's basically a regular ISA bus in a different form factor, designed for industrial applications. It's really a tradeoff on size and power consumption versus storage capacity by today's standards. I stumbled into the wearable computer realm almost by accident. Earlier experiments were intended to be mobile, but my vision was of a more traditional mobile device with the goal of networked monitoring and control of other devices. Earlier protoypes were packages in boxes, one of which was a transparent lunchbox from the drugstore.
Cables run through the jacket lining to various peripherals and to power sources.
Embedded into the left sleeve is a 4x20 character vacuum flourescent text display, and in the sleeve cuff is an integrated six-button keypad. At boot time, a menu appears on the sleeve display, allowing me to monitor and control the system and run applications. I can establish network connections, turn on appliances, monitor sensors, display GPS coordinates, phone numbers and calendars. Also integrated into the sleeve are a series of tiny LEDs used as indicators for things like network activity, resource levels, and volume levels. The jacket has a variety of capabilities for input, output, and network connections.
