Motorbike racing is one of the most popular motorsports and many fans visit circuits to watch races. However, since audiences and pit crews can only obtain limited information, it is difficult for them to get detailed information about teams except for high ranking teams and few popular teams. To solve this problem, we have already presented an information browsing system for pit crews who used wearable computers. This paper describes an extension to the system. We also applied our system to racing audiences. Since our system can provide various information such as detailed ranking tables and favorite teams, it can make supporting the teams more advantageous and entertain audiences much more.

In recent years, e-mail has become widespread explosively and it became one of very important communication tools which anyone can use easily. Here, the wearable computing has also attracted a lot of attention. In wearable computing environments, a user brings and uses his/her own computer wherever he/she goes. Therefore, we can construct a new mail system by utilizing the features of wearable computing such as "hands-free", "always on", and "supporting daily life". In this paper, we propose a mail system for wearable computing environments, called aware-mail (active wearable system applying rule-based engine for mail). Our system provides new type of communications in wearable computing environments, such as automatic mail processing according to the user's situation and exchanging information with other users by mail-based P2P communications.

The conventional approaches for constructing real-space-based 3D space on the WWW are very costly in initial modeling and in network access in its operation. The image based rendering (IBR) approach focuses on more convenient handling of the real space, but the obtained space is usually constrained by the difficulty in image analysis. As a result, the number of people who use virtual space on the WWW is still limited. In order to relax the modeling cost and the accessing cost through the WWW to let everyone enjoy easy construction and easy browsing of real and attractive virtual space, the authors propose a simple approach where they use scenic images such as those taken by a digital camera without distorting them. In the system, users can browse and construct real and attractive virtual space on the WWW more easily than ever.
