Biosensors, communicators, and controllers monitoring eye movement and methods for using them

A method for monitoring movement of a person's eye, comprising:

• placing a head-wearable biosensor assembly on a person's head, the biosensor assembly including a light source for directing light towards an eye of the person when the biosensor assembly is worn, and a camera oriented towards the eye;
• emitting light from the light source towards the eye;
• monitoring movement of the eye with the camera to generate video images of the eye;
• correlating the video images and determining the person's physical or metal state by a processor;
• and
• generating by the processor a graphical output of the movement monitored by the camera, the graphical output comprising an artificial image superimposed upon the video images of the eye to identify at least one of a size of a pupil of the eye and an eccentricity of the pupil.

A method for monitoring a person's eye, comprising:

• placing a head-wearable biosensor assembly on a person's head, the biosensor assembly comprising a light source directing light towards the person's eye and a camera oriented towards the person's eye that do not interfere substantially with the user's vision;
• emitting one or more pulses of light from the fight source, causing the eye to dilate from its relaxed state;
• monitoring the eye with the camera to determine the reaction time of the eye to return to its relaxed state;
• comparing the reaction time to reference data by a processor to determine the person's physical or mental state;
• and
• displaying video images of the eye from the video signals processed by the processor;
• the processor superimposing a graphic onto the video images to identify at least one of a size of the pupil and an eccentricity of the pupil.

A system for monitoring movement of a person's eye, comprising:

• a device configured to be worn on a person's head;
• a light source for directing light towards an eye of the person when the device is worn;
• a camera on the device for monitoring movement of the eye, the camera configured for generating video signals representing video images acquired by the camera of the eye;
• a processor communicating with the camera for processing the video signals to analyze a pupil of the eye by identifying the pupil of the eye from the video signals and at least one of a size of the pupil and an eccentricity of the pupil, the processor correlating the video signals to determine the person's physical or mental state based at least partially upon the analysis of the pupil;
• and
• a display coupled to the processor for displaying video images of the eye from the video signals processed by the processor the display superimposing a graphic onto the video images to identify at least one of a size of the pupil and an eccentricity of the pupil.
