Patent number: 6659611Abstract: A system and method for eye gaze tracking without calibrated cameras, direct measurements of specific users' eye geometries, or requiring the user to visually track a cursor traversing a known trajectory. The preferred embodiment includes two uncalibrated cameras imaging the user's eye and haying on-axis lighting. The cameras capture images of a test pattern in real space as reflected from the user's cornea, which is essentially a convex spherical mirror. The invention then extracts parameters required to define a mathematical mapping between real space and image space, including spherical and perspective transformations. The invention processes subsequent images of objects reflected from the user's eye through the inverse of the mathematical mapping to determine a gaze vector and a point of regard. Alternately, a single calibrated camera may be employed with means for estimating the eye-to-camera distance. A head-mounted embodiment that may include a laser pointer is also described.Type: GrantFiled: December 28, 2001Date of Patent: December 9, 2003Assignee: International Business Machines CorporationInventors: Arnon Amir, Myron Dale Flickner, David Bruce Koons, Carlos Hitoshi Morimoto

Patent number: 6578962Abstract: A system and method for calibration-free tracking of a user's eye gaze vector and point of regard even if substantial head movement or rotation occurs. The preferred embodiment includes two synchronized interlaced cameras, each viewing the user's eye and having on-axis lighting that is alternately modulated. An image difference between lighted and unlighted images of the eye is used to identify a user's pupil. A plane containing the gaze vector is defined by rotating a base plane through the angle in a camera image plane between a pupil center, a first glint, and a second glint. The intersection of two such planes (one from each camera), defines the gaze vector. The gaze position is the intersection of the gaze vector with the object being viewed by the user. Alternate embodiments are also described.Type: GrantFiled: April 27, 2001Date of Patent: June 17, 2003Assignee: International Business Machines CorporationInventors: Arnon Amir, Myron Dale Flickner, David Bruce Koons, Gregory Fraser Russell

Patent number: 6539100Abstract: A method and apparatus analyzes a scene to determine which pupils correspond to which subjects. First, a machine-readable representation of the scene, such as a camera image, is generated. Although more detail may be provided, this representation minimally depicts certain visually perceivable characteristics of multiple pupil candidates corresponding to multiple subjects in the scene. A machine such as a computer then examines various features of the pupil candidates. The features under analysis include (1) visually perceivable characteristics of the pupil candidates at one given time (“spatial cues”), and (2) changes in visually perceivable characteristics of the pupil candidates over a sampling period (“temporal cues”). The spatial and temporal cues may be used to identify associated pupil pairs. Some exemplary spatial cues include interocular distance, shape, height, and color of potentially paired pupils.Type: GrantFiled: January 27, 1999Date of Patent: March 25, 2003Assignee: International Business Machines CorporationInventors: Arnon Amir, Myron Dale Flickner, David Bruce Koons, Carlos Hitoshi Morimoto

Patent number: 6393136Abstract: A method and apparatus determine when a subject is looking at a specific target area by estimating a divergence angle between (1) the direction in which the subject is looking and (2) the direction from the subject directly to the target area. This technique accesses whether the subject is looking at a particular area. The invention may further condition this determination according to the subject's distance from the target area, because there is less tolerance for divergent angles when the subject is farther away. In one embodiment, the divergence angle is estimated using the position of a glint of light in the subject's pupil. The glint is created by a light source located in the target area. If the glint is sufficiently central to the pupil, with the camera and light source being near the target area, the subject is looking at the target area. At long distances, when the glint is not sufficiently discernable from the pupil, another technique may be employed to estimate divergence angle.Type: GrantFiled: January 4, 1999Date of Patent: May 21, 2002Assignee: International Business Machines CorporationInventors: Arnon Amir, Myron Dale Flickner, David Bruce Koons, Carlos Hitoshi Morimoto, Shumin Zhai

Patent number: 6345376Abstract: A computationally efficient, machine-implementable method and means for detecting and correcting errors in received codewords on-the-fly within the capacity of a linear cyclic code using ultra-fast error location processing. Each error locator polynomial of degree t over a finite Galois field derived from a codeword syndrome is mapped into a matrix representative of a system of linear simultaneous equations related to the polynomial coefficients. Roots indicative of error locations within the codeword are extracted from the matrix by a modified Gaussian Elimination process for all the roots where t≦5 and at least one root plus a subset of candidate roots from the finite field for iterative substitution where t>5. Corrected values are separately determined and correction is secured by logically combining the corrected values with the codeword values in error at the error locations represented by the roots.Type: GrantFiled: July 18, 2000Date of Patent: February 5, 2002Assignee: International Business Machines CorporationInventors: Charles Edwin Cox, Myron Dale Flickner, James Lee Hafner, Martin Aureliano Hassner, Barry Marshall Trager, Shmuel Winograd

Autonomous system for recognition of patterns formed by stored data during computer memory scrubbing
Patent number: 6279128Abstract: A system for continuous monitoring and autonomous detection of patterns in the main memory subsystem of a computer system. The invention can be embodied as an extension to existing memory scrubbing hardware to permit stored code pattern analysis and identification during the autonomous transparent memory scrubbing process. A library of stored target signatures is provided to which code signatures are compared during analysis. Code signatures may be derived directly from the memory subsystem data pattern or may be indirectly and more efficiently derived from the error correction code (ECC) string associated with the stored data pattern. This invention is directly applicable to computer virus detection and neutralization systems.Type: GrantFiled: December 29, 1994Date of Patent: August 21, 2001Assignee: International Business Machines CorporationInventors: William Carlisle Arnold, Jehoshua Bruck, Jeffrey Owen Kephart, Gregory Bret Sorkin, Steve Richard White, David Michael Chess, Charles Edwin Cox, Myron Dale Flickner -
Patent number: 6204828Abstract: A computer-driven system aids operator positioning of a cursor by integrating eye gaze and manual operator input, thus reducing pointing time and operator fatigue. A gaze tracking apparatus monitors operator eye orientation while the operator views a video screen. Concurrently, the computer monitors an input device, such as a mouse, for mechanical activation by the operator. According to the operator's eye orientation, the computer calculates the operator's gaze position. Also computed is a gaze area, comprising a sub-region of the video screen that includes the gaze position. This region, for example, may be a circle of sufficient radius to include the point of actual gaze with a certain likelihood. When the computer detects mechanical activation of the operator input device, it determines an initial cursor display position within the current gaze area. This position may be a predetermined location with respect to the gaze area, such as a point on the bottom of the gaze area periphery.Type: GrantFiled: March 31, 1998Date of Patent: March 20, 2001Assignee: International Business Machines CorporationInventors: Arnon Amir, Myron Dale Flickner, Steven Carlyle Ihde, Shumin Zhai
