Abstract: A method of operating a computer game is provided. The method includes, executing the computer game, the computer game having a plurality of graphical objects within a three-dimensional scene, some of the plurality of graphical objects drawn as two-dimensional projections on a display, iteratively tracking a player's eye movement as associated with the two-dimensional projection, calculating a region associated with the player's gaze based upon the iterative tracking, identifying one or more fixation object(s) from the plurality of graphical objects based upon the calculated region within the three-dimensional scene, and operating the computer game based upon the identified fixation objects.

Abstract: Objects associated with fixation regions are used to support training tasks that are characterized by operation within a dynamic 3D environment, problem-solving that involves user multi-tasking, fast decisions, heavy workloads, potential for unexpected events, and the need for high-performance skills. The invention is ideally suited to measure the nuances associated with maintaining situation awareness in such tasks where dynamic 3D environments that support problem solving with high cognitive fidelity have already been developed. Potential training application areas include urban warfighting, night vision goggle use, aircraft piloting, helicopter operation, remote control of vehicles and robots, night driving, air traffic control, and quarterback decision-making.

Abstract: Objects associated with eye fixations are used to support training tasks that are characterized by operation within a dynamic 3D environment, problem-solving that involves user multitasking, short decision time periods, heavy workloads, potential for unexpected events, and the need for high-performance skills. The invention is ideally suited to measure the nuances associated with maintaining situation awareness in such problems where dynamic 3D environments that support problem solving with high cognitive fidelity have already been developed. Potential training application areas include urban warfighting, night vision goggle use, aircraft piloting, helicopter operation, remote control of vehicles and robots, night driving, and air traffic control.

Abstract: A system for detecting and recording eye-tracking data by presenting to an observer a display image with an area in focus surrounded by blurred areas. The observer may shift the focus area within the image by head movements which are wirelessly transmitted to a receiver and used to modify the displayed image. This system solves that part of the eye-tracking problem that is most critical for measuring cognitive processes.

Abstract: Paper documents are automatically converted into a hypertext-based format so that they can be accessed through electronic networks, including the Internet, or via non-volatile transfer media such as disks or CD-ROMs. The invention generalizes the concept of form-based recognition while extending the concept of document retrieval to include document structure knowledge, thereby providing the advantages found in both form-based recognition (utilization of document structure knowledge) and image-based information retrieval (robustness). In a preferred embodiment, a method according to the invention enables direct translation of a paper document into a hypertext-based format so that it may be directly accessed through the Internet using current browsers such as Mosaic, Netscape and Microsoft's Explorer.
