BIOSENSORS, COMMUNICATORS, AND CONTROLLERS MONITORING EYE MOVEMENT AND METHODS FOR USING THEM
First Claim
1. A system for controlling a computing device, comprising:
- a device configured to be worn on a person'"'"'s head;
a camera on the device for monitoring movement of at least one eye of the person, the camera configured for generating signals representing video images of the eye acquired by the camera;
a display disposed adjacent the device such that a pointer on the display is viewable by the person wearing the device; and
a processor coupled to the camera for processing the signals to monitor movement of the eye relative to a reference frame on the display, the processor coupled to the display for causing the pointer to move on the display based upon movement of the eye relative to the reference frame.

Abstract
Biosensor, communicator, and/or controller apparatus, systems, and methods are provided for monitoring movement of a person'"'"'s eye. The apparatus includes a device configured to be worn on a user'"'"'s head, a light source for directing light towards one or both eyes of the user, one or more image guides on the device for viewing one or both eyes of the user, and one or more cameras carried on the device and coupled to the image guides for acquiring images of the eyes and/or the user'"'"'s surroundings. The apparatus may include a cable and/or a transmitter for transmitting image data from the camera to a remote location, e.g., to processor and/or display for analyzing and/or displaying the image data. A system including the apparatus may be used to monitor one or more oculometric parameters, e.g., pupillary response, and/or to control a computer using the user'"'"'s eyes instead of a mouse.

11. A method for controlling a computing device using a device worn on a user'"'"'s head, the device comprising a camera comprising an objective lens directed towards at least one eye of the user, the computer device comprising a display including a pointer displayed on the display, the method comprising:
-
monitoring movement of the at least one eye using the camera; and
correlating movement of the at least one eye relative to the pointer on the display to cause the pointer to follow movement of the at least one eye. - View Dependent Claims (12, 13)

14. A method for controlling a computing device using a device worn on a user'"'"'s head, the device comprising a camera comprising an objective lens directed towards at least one eye of the user, the computer device comprising a display including a pointer displayed on the display, the method comprising:
-
monitoring movement of the at least one eye using the camera;
analyzing image data of the at least one eye from the camera while the at least one eye is substantially stationary to determine the location of the pupil of the at least one eye to provide a base location; and
correlating movement of the at least one eye relative to the base location on the display to cause the pointer to follow movement of the at least one eye. - View Dependent Claims (15, 16, 17)
