ABSTRACT
One of the main goals of wearable computers is to allow users to access computational resources whenever and wherever they are in the environment. Compared to virtual and augmented reality display systems, in which users are confined to the range of motion associated with the length of the cable connecting the display hardware and rendering platform, wearable computers allow complete freedom of motion within the real world. This mobility generally requires three standard system components, each worn on the user’s body. These are the computer unit, the power supply, and the input devices. The computer unit functions to store, retrieve, and process information. Typically belt or wrist worn, it houses the CPU, motherboard, hard drive, and memory.
