Abstract:
A method and apparatus are provided for analyzing the light pattern produced on a photodetector array. The signal produced by the array is filtered with a low pass filter and the output of the filter is differentiated to obtain either the first or second derivative of the filtered signal for one or more points in the pattern. The zero crossing of the differentiated signal is detected and the zero crossing point is timed relative to a further point, e.g., the start of the scan of the array, so as to obtain an output related to the position of the corresponding point or points in the pattern.
Abstract:
Disclosed are methods and apparatus for instructing persons using computer based programs and/or remote instructors. One or more video cameras obtain images of the student or other participant. In addition images are analyzed by a computer to determine the locations or motions of one or more points on the student. This location data is fed to computer program which compares the motions to known desired movements, or alternatively provides such movement data to an instructor, typically located remotely, who can aid in analyzing student performance. The invention preferably is used with a substantially life-size display, such as a projection display can provide, in order to make the information displayed a realistic partner or instructor for the student. In addition, other applications are disclosed to sports training, dance, and remote dating.

Abstract:
A method and apparatus for interactive TV camera based games in which position or orientation of points on a player or of an object held by a player are determined and used to control a video display. Both single camera and stereo camera pair based embodiments are disclosed, preferably using stereo photogrammetry where multi-degree of freedom information is desired. Large video displays, preferably life-size may be used where utmost realism of the game experience is desired.
Abstract:
Method and apparatus are disclosed to enable rapid TV camera and computer based sensing in many practical applications, including, but not limited to, handheld devices, cars, and video games. Several unique forms of social video games are disclosed.
Abstract:
Affordable methods and apparatus are disclosed for inputting position, attitude (orientation) or other object characteristic data to computers for the purpose of Computer Aided Design, Painting, Medicine, Teaching, Gaming, Toys, Simulations, Aids to the disabled, and internet or other experiences. Preferred embodiments of the invention utilize electro-optical sensors, and particularly TV Cameras, providing optically inputted data from specialized datum's on objects and/or natural features of objects. Objects can be both static and in motion, from which individual datum positions and movements can be derived, also with respect to other objects both fixed and moving. Real-time photogrammetry is preferably used to determine relationships of portions of one or more datums with respect to a plurality of cameras or a single camera processed by a conventional PC.
Abstract:
Method and apparatus are disclosed for providing a novel video gaming experience on a play surface on which reconfigurable information is displayed.
Abstract:
The invention provides a method for providing human input to a computer which allows a user to interact with a display connected to the computer. The method includes the steps of placing a first target on a first portion of the user's body, using an electro-optical sensing means, sensing data related to the location of the first target and data related to the location of a second portion of the user's body, the first and second portions of the user's body being movable relative to each other, providing an output of the electro-optical sensing means to the input of the computer, determining the location of the first target and the location of the second portion of the user's body, and varying the output of the computer to the display based upon the determined locations for contemporaneous viewing by the user.
Abstract:
New methods and apparatus are provided for efficiently and safely providing controls and displays therefore, particularly, but necessarily to be used within the center stack region of a vehicle instrument panel. The apparatus utilizes, in most embodiments, a rear projection display and machine vision sensing of control position and, optionally, finger touch. A very stylistic and easy to use instrument panel results which can be programmed or otherwise provided in many different forms to suit different users or option package designs.
Abstract:
Disclosed are new methods and apparatus particularly suited for applications in a vehicle, to provide a wide range of information, and the safe input of data to a computer controlling the vehicle subsystems or “Telematic” communication using for example GM's “ONSTAR” or cellular based data sources. Preferred embodiments utilize new programmable forms of tactile touch screens and displays employing tactile physical selection or adjustment means which utilize direct optical data input. A revolutionary form of dashboard or instrument panel results which is stylistically attractive, lower in cost, customizable by the user, programmable in both the tactile and visual sense, and with the potential of enhancing interior safety and vehicle operation. Non-automotive applications of the invention are also disclosed, for example means for general computer input using touch screens and home automation systems.
