Title: Carroll M Steele: Innovator in Eye Tracking Technology
Introduction
Carroll M Steele is a notable inventor based in Los Altos, California. He has made significant contributions to the field of eye tracking technology, holding 2 patents that showcase his innovative approach to measuring eye movement and refractive power.
Latest Patents
One of Steele's latest patents is the "Accurate Three Dimensional Eye Tracker." This invention measures the point in three-dimensional space on which the eye is fixed, utilizing a two-dimensional double Purkinje eye tracker for eye movement measurement. It features an automatic optometer that assesses the refractive power of the eye, all while maintaining a common optical path to ensure accurate measurements. The design incorporates polarizers and mechanical stops to provide optical isolation and minimize interference.
Another significant patent is the "Double Purkinje Eye Tracker." This device measures the fixation point of the eye by reflecting an input image into the eye and directing the resulting Purkinje images back into the tracking mechanism. The system employs closed-loop servo mechanisms to keep the Purkinje images centered on their respective detectors, allowing for precise measurement of both translational and rotational eye movements.
