Problems solved by technology

However, such devices require the user's eyes to remain in constant contact with the camera
Also, they cannot monitor eyelid movement if the user turns their head sideways or down, swivels, sticks out of the vehicle, if the user moves back and forth quickly, or if the camera moves relative to the person
Additionally, such cameras may be an invasion of privacy and / or have problems seeing through glasses, sunglasses, and even contact lenses, and they do not operate effectively in daylight

Embodiment Construction

[0046] Referring to the drawings, FIG. 1 shows a patient 10 on a hospital bed 12 wearing a detection device 30 for detecting eye and / or eyelid movement of the patient 10 . Detection means 30 may include any of the biosensor means described herein, which may be used to monitor, for example, intentional eye movement for intentional communication of information, for monitoring unintentional eye movement (e.g., drowsiness or other conditions), and and / or for controlling one or more electronic devices (not shown). The detection device 30 may be connected to a processing box 130 for converting detected eye and / or eyelid movements into a data stream, an intelligible message, and / or into other information, which may communicate, for example, using a video display 50 Medical care provider 40 communication.

[0047] Referring to FIGS. 2 , 6A , and 7A , an exemplary embodiment of an apparatus or system 14 is shown that includes an aimable and focusable detection device 30 connectable to...

Abstract

The present invention provides biosensor, communicator, and / or controller devices, systems, and methods for monitoring the movement of a human eye. The apparatus includes: a device for wearing on a user's head; a light source for directing light to 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 The device carries one or more cameras connected to the image guide for obtaining images of the eye and / or the user's surroundings. The device may include a cable and / or a transmitter for transmitting image data from the camera to a remote location, eg, to a processor and / or display for analyzing and / or displaying the image data. A system including the device can be used to monitor one or more eye movement parameters, eg pupillary response, and / or to control a computer using the human eye instead of a mouse.

Description

technical field [0001] The present invention generally relates to devices, systems, and methods for monitoring the movement of a human eye, for example, for monitoring fatigue, intentional communication, and / or for monitoring motion based on the eyes, eyelids, and / or one or both eyes of a person. Apparatus, systems and methods for controlling the motion of other components of a device. Background technique [0002] It has been proposed to use the movement of a person's eyes to monitor unconscious states, such as the person's wakefulness or drowsiness. For example, US Patent No. 3,863,243 discloses a device that can sound an alarm to warn a person using the device that he is about to fall asleep. The device includes a frame similar to a set of lenses on which optical fibers and photocells are mounted, wherein when the frame is worn, the lenses face the user's eyes. The photoelectric element detects the intensity of light reflected by the human eye, that is, the intensity of...
