In order to infer intent from gesture, a broad classification of types of gestures into five main classes is introduced. The classification is intended as a generally applicable basis for incorporating the understanding of gesture into human-robot interaction (HRI). Examples from human-robot interaction show the need to take into account not only the kinematics of gesture, but also the interactional context. Requirements for the operational classification of gesture by a robot interacting with humans are suggested and initial steps in its deployment are discussed.

This paper proposes a detection method of moving ships from the navigational image sequence that was taken with cameras installed on the bridge of the ship. The image is influenced by roll and pitch of the ship. Therefore, usual technique of image processing cannot be used such as Finite Difference method. Moreover, as many sea waves appear in the images, the image cannot be dealt without rejecting sea waves. The technique in this paper proposes how to get rid of the influence of roll, pitch and sea waves. After that, we detect the ships. An interval between each of the frames is one-thirty second in this experiment. The size of the images is 640 pixels in width and 480 pixels in height. At first, the frames are segmented into about 5000 regions using brightness value of the image. About 100 regions were estimated with the ship. Each region was matched with another two frames, which passed 0.33 second and 0.66 second. 0.33 second corresponds to 10 frames. The movement of the ship is less than 50 pixels in this interval. The SSDA method is used for matching processing to be more efficiently. Both the coordinate points of an original region and the matched one are recorded on the table. It is used to calculate the deflection, the speed and the direction of the moving vector of each region. The ships can be detected with these parameters. The detected ships can be displayed clearly as a result of processing. We have taken a lot of video images in Tokyo Bay and Tokyo Port. It becomes possible to show that the ships can be detected from the video images.

This paper studies the necessity of the robot soccer over the Internet on the basis of analysing the tele-operation system, presents a new system architecture of the robot soccer over the Internet based on C/S, describes the information flowchart of the local site and the remote sites, realizes a human-robots interactive game over the internet, does some researches on its characteristics, and describes the architecture, software programming and the key technology of each parts in details. The whole system adopts the technology of Windows operation system, VC+ +, and Winsock network programming. The distributed simulation system of robot soccer over the Internet is based on HLA. The competitions that rely on the regulations were finished. The results show that this system can simulate the whole process of soccer competitions of human being, and meet the demands of stability and reliability.

Recent advances and research trends for intelligent vehicles were studied. Vehicle-state sensing focuses on measuring a vehicle's movement and monitoring its actuators. Individual-vehicle-control research focuses mainly on guaranteeing driving safety. The results suggest that intervehicle, vehicle-roadside, and vehicle-driver information sharing currently the most attractive trend in intelligent-vehicle research.

The reliable fuzzy control with guaranteed cost for T-S fuzzy systems with actuator failure is proposed in this paper. The cost function is a quadratic function with failure input. When the initial state of such systems is known, a design method of the reliable fuzzy controller with reliable guaranteed cost is presented, and the formula of the guaranteed cost is established. When the initial state of such systems is unknown but belongs to a known bounded closed domain, a notion of the reliable domain guaranteed cost (RDGC) for such systems is proposed. For two classes of initial state domain, polygon domain and ellipsoid domain, some design methods for reliable fuzzy controllers with the RDGC are provided. The efficiency of our design methods is finally verified by numerical design and simulation on the Rossler chaotic system.
