Abstract

Abstract In a preferred embodiment, an apparatus for eye tracking, including: an illuminator; reflection apparatus to reflect illumination from the illuminator onto a surface of a windshield of a vehicle in which the windshield is installed, such that the illumination is reflected onto at least an eye of a person in the vehicle, and to reflect an image of the at least an eye; and a sensor to receive a reflection of the image of the at least an eye reflected by the reflection apparatus and to produce an output signal representative thereof.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 101 words
An apparatus for eye tracking, comprising: (a) an illuminator (54); (b) reflection means (40) to reflect illumination from said illuminator onto a surface (58) of a windshield (42) of a vehicle in which said windshield (42) is installed, such that said illumination is reflected onto at least an eye (60) of a person in said vehicle, and to reflect an image of said at least an eye (60); and (c) a sensor (50) to receive a reflection of said image of said at least an eye (60) reflected by said reflection means (40) and to produce an output signal representative thereof.
Claim 2
Dependent Claim 27 words
An apparatus for eye tracking, as defined in Claim 1, wherein: said reflection means (40) is at least part of a head up display in said vehicle.
Claim 3
Dependent Claim 123 words
An apparatus for eye tracking, as defined in Claim 1, further comprising: (a) a controller (52) operatively connected to said sensor (50) to receive said output signal; (b) said controller (52) configured to cause said sensor (50) to view an entire face of said person to obtain predetermined facial features (70, 80, 90, 100, 110) and to produce a signal representative of said facial features (70, 80, 90, 100, 110); and (c) said controller (52) configured to receive said signal and, if said person is recognized from said facial features (70, 80, 90, 100, 110), to retrieve a stored ocular profile (250) of said reflection and to use said ocular profile (250) for eye tracking while viewing said entire face of said person.
Claim 4
Dependent Claim 49 words
An apparatus for eye tracking, as defined in Claim 3, wherein: if said person is not recognized, said controller (52) causes said sensor (50) to view only said eye (60) of said person and uses such information to create an ocular profile (250) therefor for use in eye tracking.
Claim 5
Dependent Claim 18 words
An apparatus for eye tracking, as defined in Claim 1, wherein: all elements of said apparatus operate automatically.
Claim 6
Dependent Claim 20 words
An apparatus for eye tracking, as defined in Claim 1, wherein: all elements of said apparatus operate without mechanical linkages.
Claim 7
Dependent Claim 16 words
An apparatus for eye tracking, as defined in Claim 1, wherein: said apparatus uses SXGA resolution.
Claim 8
Dependent Claim 36 words
An apparatus for eye tracking, as defined in Claim 3, wherein: if said person is not recognized, said controller (52) restricts how a vehicle can be operated and/or restricts access to certain areas of said vehicle.
Claim 9
Dependent Claim 33 words
An apparatus for eye tracking, as defined in Claim 3, wherein: if contact with said eye is lost, said controller (52) uses said entire face of said person to locate said eye (60).
