An imaging system has an area in which an object being captured is placed, a plurality of imaging devices, or cameras for captured different sides of the object, the imaging devices, or cameras being connected together through a communication path to take a picture of the sides of the object from a plurality of directions, and control means provided so that, when one of the cameras tracks the object, the remaining cameras can be controlled to automatically change their pan, tilt and focus settings and track the object.

Abstract: It is made possible to view a high-resolution clear stereoscopic image from any direction without taking the projection timing of two-dimensional images into consideration. First and second polygonal mirrors each including mirrors arranged in a ring form around a rotation axis of a screen are disposed. An electronic projector is disposed on an extended line of the rotation axis of the screen so as to be opposed to mirror surfaces of the polygonal mirrors. The electronic projector emits concentrically arranged first and second frame image groups each including frame images arranged in a ring form. The first and second frame image groups are reflected respectively by the first and second polygonal mirrors and projected onto the rotating screen. As the screen rotates, each of the first and second image groups is projected onto the screen and displayed in order from frame image to frame image.

Abstract: A display unit with a touch panel to move a touch-driven member such as a functional button to a desired position through a touch operation. By touching a draggable icon displayed on a screen with a finger, the icon is changed in color to indicate that the user can drag the icon. Then, by pushing the icon, the icon is changed in size and color to indicate that the user can drag the icon. As by reducing the pushing force to touch on the icon, and moving the finger, the icon is dragged following the finger. As by pushing the icon with the finger at a predetermined position, the icon is set at this position and changed in size and color. When releasing the finger from the icon, the icon is settled at this position.

Abstract: The field of view of a video camera is set to include electric appliances such as a refrigerator, TV set, air conditioner and lamp installed within a room. When the user operates a remote controller to emit a visible laser beam toward a controlable range including these electric appliances set within this field of view, and designate a certain one of the appliances by the resulting pointer within the controlable range, the video camera for extracting only the visible laser beam of a wave length picks up this pointer, and a control box detects the position of the pointer within the controlable range from the output of the camera so that the appliance designated by this pointer can be detected and remotely controlled by use of the remote controller.

Abstract: Projector units in a table display a content list, a content selected by the content list and the like, on screens. Infrared rays are uniformly irradiated to the screens from a plurality of infrared LED's. A camera unit images the silhouette of an object touching the screens to judge whether the silhouette is formed by a pointing member such as a fingertip for touching the content list or by an object other than the pointing member. If it is judged that the pointing member such as a fingertip touches the screens, a content menu is selected from the content list.

Abstract: An individual information screen is displayed for each of operators on the same table surface and it is possible to surely acquire shared information required for conversation between the operators. The data on each of individual information screens cannot be viewed by the other operators. A shared information screen and a plurality of individual information screens are displayed in a display surface arranged on a table surface. The individual information screens are used by each operator and display individual information on each of the operators. Among the individual information displayed on each individual information screen, those which can be viewed by the other operators may be displayed as shared information on the shared screen by a predetermined operation on the respective individual information screen. It becomes possible to display the individual information screens at predetermined positions at arbitrary positions on the table surface.

Abstract: A program and a system for judging the learning conditions of each user from behavior information or living body information of the user, and for evaluating contents or lesson details used for learning. A change of concentration during learning is judged from a result of a blood flow rate measured in time series by a near infrared measuring device. Further, the result of the judgment and a result of analysis of user's behavior (image recognition, voice recognition and instrument input operation event) are analyzed synthetically. Thus, the change of attention of the user is extracted, and the learning conditions of the user are judged. True learning conditions of the user can be grasped in real time, and the learning contents or the lesson details can be evaluated. Further, the result of the evaluation can be reflected on the next lesson so as to enhance the learning effect.
