System and method for monitoring eye movement
First Claim
1. A system for monitoring movement of a person'"'"'s eye, comprising:
- a device configured to be worn on a person'"'"'s head;
an array of emitters on the device for directing light towards an eye of the person when the device is worn, the array of emitters configured for projecting a reference frame towards the eye; and
a camera oriented towards the eye for monitoring movement of the eye relative to the reference frame.

Abstract
Apparatus for monitoring movement of a person'"'"'s eye, e.g., to monitor drowsiness. The system includes a frame that is worn on a person'"'"'s head, an array of emitters on the frame for directing light towards the person'"'"'s eye, and an array of sensors on the frame for detecting light from the array of emitters. The sensors detect light that is reflected off of respective portions of the eye or its eyelid, thereby producing output signals indicating when the respective portions of the eye is covered by the eyelid. The emitters project a reference frame towards the eye, and a camera on the frame monitors movement of the eye relative to the reference frame. This movement may be correlated with the signals from the array of sensors and/or with signals from other sensors on the frame to monitor the person'"'"'s level of drowsiness.

21. A system for monitoring movement of a person'"'"'s eye, comprising:
-
a frame configured to be worn on a person'"'"'s head;
an array of emitters on the frame for directing light towards an eye of the person when the frame is worn, the array emitters configured to project a reference frame towards the eye;
an array of sensors on the frame in a predetermined relationship with the array of emitters for detecting light from the array of emitters that is reflected off of respective portions of the eye or its eyelid, each sensor producing an output signal indicating when the respective portion of the eye is covered or not covered by the eyelid;
a camera on the frame for monitoring movement of the eye relative to the reference frame, the camera configured for producing a video signal of a region of the eye and the reference frame; and
a transmitter coupled to the sensor for wireless transmission of the output signal and the video signal to a remote location. - View Dependent Claims (22, 23)

24. A method for monitoring movement of a person'"'"'s eye using a detection device including an array of emitters that are directed towards an eye of the person when the detection device is worn, and a camera oriented towards the eye, the method comprising:
-
emitting light from the array of emitters towards the eye to project a reference frame onto the eye;
monitoring movement of the eye relative to the reference frame with the camera; and
generating a graphical output of the movement monitored by the camera relative to the reference frame. - View Dependent Claims (25, 26, 27, 28, 29, 30)
