Eye movement monitoring technique

Claim 2

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: a support adapted for mounting on the head of the subject; a light source adapted to direct light at an eye of said subject; detector means aimed at the subject's eye for sensing reflections from the eye of light emitted by said light source; a CCD camera secured to said support and aimed to record at least part of the scene within the subject's field of vision.

Claim 3

The apparatus of claim 1, wherein said support is a spectacle frame.

Claim 4

The apparatus of claim 1 or 2 wherein said detector means comprises two detectors and further comprising a position-processing-circuit means coupled to said detectors for converting the output of said detectors to a signal for use on video equipment to display eye position.

Claim 6

The apparatus of claim 4, further comprising a focus lens and a zoom lens affixed to the further CCD camera.

Claim 7

The apparatus of claim 4, 5 or 6, wherein the further CCD camera is secured to the temple portion of the spectacle frame and said light source is secured to the nose bridge of said spectacle frame and further comprising a mirror secured to the spectacle frame for directing reflected light from the eye into said further CCD camera.

Claim 8

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: a frame adapted for mounting on the head of the subject of a type normally used to support corrective lenses and having a pair of temples, two lens supports with each attached at one end to a temple and at the other to a nose bridge; a light source secured to said frame and adapted to direct light at an eye of said subject when the frame is.worn in place by the subject; detector means secured to said frame for receiving light reflected by the subject's eye when the frame is worn in place by the subject for sensing reflections from the eye of light emitted by said light source; and means secured to said frame and aimed to record at least part of the scene within the subject's field of vision.

Claim 9

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: a frame adapted for mounting on the head of the subject of a type normally used to support corrective lenses and having a pair of temples, two lens supports with each attached at one end to a temple and at the other to a nose bridge; a light source secured to said frame and adapted to direct light at an eye of said subject when the frame is.worn in place by the subject; detector means secured to said frame for receiving light reflected by the subject's eye when the frame is worn in place by the subject for sensing reflections from the eye of light emitted by said light source; and means secured to said frame and aimed to record at least part of the scene within the subject's field of vision.

Claim 10

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: a support adapted for mounting on the head of said subject; a light source secured to said support and adapted to direct light at an eye of said subject when the support is worn on the subject's head; detector means secured to said support and aimed at the subject's eye when worn on the head; means secured to said frame and aimed to record at least part of the scene within the subject's field of vision; and means on said support for securing corrective lenses to said frame and facilitating the installation and removal of such lenses.

Claim 11

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: a support adapted for mounting on the head of said subject; a light source secured to said support and adapted to direct light at an eye of said subject when the support is worn on the subject's head; detector means secured to said support and aimed at the subject's eye when worn on the head; means secured to said frame and aimed to record at least part of the scene within the subject's field of vision; and means on said support for securing corrective lenses to said frame and facilitating the installation and removal of such lenses.

Claim 12

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: (a) a spectacle frame having a pair of temples, a pair of lens supports and a nose bridge; (b) a light source adjustably secured to said frame and aimed at the eye of said subject when the frame is worn; (c) detector means adjustably secured to said frame for receiving light from the subject's eye when said frame is worn; (d) a CCD camera secured to said frame and aimed to record at least part of the scene within the subject's field of vision; (e) camera circuitry coupled to said CCD camera for converting its signal to one compatible with video equipment for display; (f) detector circuitry coupled to said detector means for providing an eye movement signal compatible with video equipment for display; and (g) means coupled to the detector circuitry and camera circuitry for combining the same signal and eye movement signals in a superimposed manner.

Claim 13

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: (a) a spectacle frame having a pair of temples, a pair of lens supports and a nose bridge; (b) a light source adjustably secured to said frame and aimed at the eye of said subject when the frame is worn; (c) detector means adjustably secured to said frame for receiving light from the subject's eye when said frame is worn; (d) a CCD camera secured to said frame and aimed to record at least part of the scene within the subject's field of vision; (e) camera circuitry coupled to said CCD camera for converting its signal to one compatible with video equipment for display; (f) detector circuitry coupled to said detector means for providing an eye movement signal compatible with video equipment for display; and (g) means coupled to the detector circuitry and camera circuitry for combining the same signal and eye movement signals in a superimposed manner.

Claim 14

Apparatus for monitoring eye movements of a subject and simultaneously recording the scene being viewed by said subject comprising: (a) a spectacle frame having a pair of temples, a pair of lens supports and a nose bridge; (b) a light source adjustably secured to said frame and aimed at the eye of said subject when the frame is worn; (c) detector means adjustably secured to said frame for receiving light from the subject's eye when said frame is worn; (d) a first optical lens secured to said frame and aimed to record at least a part of the scene within the subject's field of vision; (e) means for conveying light from said lens; (f) means for combining the subject's eye movements from the detector means with light from said conveying means to provide a signal compatible with video equipment for display; and (g) means for displaying the combined scene and subject eye movements in superimposed fashion.
