In this paper, we developed an information visualization system of the ubiquitous environment for a wearable computer using a small head-mount display. A wearable computer provides the user unlimited computer access in everyday places. The user of a wearable computer can acquire and process various information by hands-free operation. In this case, a tiny display communicates information from a wearable computer to the user. Downsizing a wearable computer's display is a result of the pursuit of portability. However, downsizing the display reduces the amount of information that can be displayed. Raising the resolution of a wearable display is sure that it can increase the amount of information displayed at once. However, information crowded onto the tiny display would be difficult to comprehend. Our information visualization system solves the above problems. It enables us to display the information of sensors equipped in an environment efficiently using a tiny display. We used a 12mm-square HMD for our system. We also demonstrate the potential of our system by evaluating experimental results.
