This system is an interface realized with the symbiosis of the input/output of wind and graphics. This system brings the new communication medium of "wind" into the bidirectional interaction between the virtual environment and the real environment by integrating the graphic presentation with the input and output of wind on a special screen. The user can interact with the virtual environment in the screen through his/her breath and wind emission. Conversely, actions from the virtual environment to the user are performed by wind changing dynamically. As a result, the user can share not only sights and sounds but also the cutaneous sensation by wind with the system, and interact with the virtual environment feeling a non-conventional deep relationship.

Recently, there are many needs for small tracking camera systems to be mounted on mobile platforms, such as bikes, cars, etc., to tracking some targets stably in a perturbation environment. To meet the needs, a small tracking camera system has been developed by authors. The purpose of the tracking camera system is both to stabilize the camera and to track the target simultaneously. The system consists of three axes driven by DC motors with encoders, to form velocity and position control loop. Outside the loop, another position control loop is composed based on the integration of both rate gyro and inclinometer by a designed filter, to stabilize the camera. And besides the two loops, another position compensation loop is formed by introducing the camera position information, to track the target. This paper describes the system configuration, the design of controller as well as sensor systems, and the experimental results on the tracking performance.

Computer graphic (CG) images exist only in a display device, and cannot physically interact with the real world, whereas robots have a physical existence that can be controlled by a computer. In this study, we developed robots that behave along with fiducial graphics. This technology can be used to synchronize physical actions based on the graphics shown in the display devices. Figure 1 shows tiny robots controlled by this technique.

BYU-BYU-View is a novel interface realized with the symbiosis of the input/output of wind and the computer graphics. "BYU-BYU" is a japanese onomatopoeia for a howling wind. It adds a new element, that is, "wind", to the direct interaction with a user and a virtual environment, and the communication through a network, by integrating the graphic presentation with the input and output of wind on a special screen.
