Spectral flying spot eye-tracker and heads-up display

摘要

A tracking and display system for an eye of a person is incorporated into eyewear having at least one lens and being positionable in front of the eye or eyes with attachment hardware. A circuit with a power source is fixed with the eyewear and includes at least one multispectral LED adapted to project light towards the eye and at least one multispectral light detector adapted to receive light reflected from the eye. As such, movement, anatomy and physiology of the eye are determined according to an organized pattern of projected light reflected and received by the at least one detector. To display an image, light from the at least one multispectral LED is conveyed by at least one optical fiber to an eye-facing surface of a lens of the eyewear and then onto the retina of the person's eye to form a visible heads-up display image.

主权项

1. A tracking and display system for sensing movement, anatomy and physiology of an eye of a person, comprising:
eyewear having at least one lens and positionable in front of the eye with attachment hardware, wherein the eyewear is a pair of eyeglasses having a front frame and two temple pieces extending from the front frame; at least one multispectral LED fixed with the one of the temple pieces of the eyewear and adapted to project light towards the eye; a cooperative medium between the at least one multispectral LED and the at least one lens, the cooperative medium conveying light from the LED to the lens; at least one multispectral light detector fixed with the eyewear and adapted to receive light reflected from the eye; whereby movement, anatomy and physiology of the eye are determined according to an organized pattern of project light reflected and received by the at least one detector.
