Abstract: Computer vision systems provide a user a view of a scene whereby an image of the scene may have been augmented with information generated by a computer. Computer vision systems of the present invention include graphical user interfaces which have been discovered to operably interact with geometric constructs of a user environment, objects within a scene, perspective of the scene, image features of a signal which represents the scene, among others. These graphical user interfaces of the invention do not behave as those known because operation of these interfaces depends on properties and features particular to computer vision systems which have position and attitude determining means.

Abstract: The following invention is primarily concerned with new and improved systems for viewing a sporting event. In particular, systems which combine images of a real scene with computer generated imagery where the computer generated imagery is particular to the position and pointing attitude of the device. Being useful to spectators of the game baseball, the device can produce images showing where a strike zone is relative to the position of the players; can produce images of ball tracks; of replays and many other forms of information having characteristics dependent on a viewer's position and attitude.

Abstract: Vision systems having knowledge of position and attitude can reliably determine what scenes are being addressed by the system. Real images of the scene can then be augmented with computer generated information which relates to the known scene. Since the level of detail or resolution is not restricted in computer generated models, a system can continue to provide further magnified images without limit. As magnification increases, the amount of information presented to a user from images of the real scene decreases but computer generated imagery continues to provides realistic images which represent scenes being addressed by the apparatus. Computer generated imagery is combined with an image of a real scene to form an augmented image which is presented to the user aligned to the viewing direction of the device at any desired magnification.
