System design of event space information support utilizing CoBITs

One target of a ubiquitous computing environment is to aid users in getting necessary information and services in a situation-dependent form. We proposed a location-and orientation-based information support system using the compact battery-less information terminal (CoBIT). The CoBIT is a small, low cost communication terminal that uses only energy from the information carrier and the user. We realized an example of CoBIT, which downloads sound information and uploads users´ positions and orientations along with signs from users. We emphasize the importance of focusing on event space as a first step toward realizing ubiquitous information support. We propose the use of CoBIT as a common terminal. Thereby, service embedded interactive map supported by various types of sensors and displays proposed to enhance benefits of the CoBIT.
