Title: Yatong An: Innovator in Eye Tracking Technology
Introduction
Yatong An is a prominent inventor based in Redmond, WA (US), known for his contributions to eye tracking technology. He holds a total of 10 patents that showcase his innovative approach to enhancing the accuracy and functionality of eye tracking systems.
Latest Patents
One of his latest patents is titled "Absolute phase unwrapping for fringe analysis in an eye tracking application." This invention involves an eye tracking system that utilizes a fringe projector, a camera, and an illumination module. The projector projects a periodic fringe pattern onto the eye, while the camera captures the reflection of this pattern. Techniques such as Fourier transform and wavelet transform are employed to determine the phase of the fringe pattern, resulting in a wrapped phase map. The system also incorporates spatial phase unwrapping to generate a relative unwrapped phase map, which is then converted to an absolute unwrapped phase map using detected glints on the eye.
Another significant patent is "Three-dimensional (3D) compressive sensing based eye tracking." This system employs single photon avalanche diode (SPAD) sensors to achieve high-resolution depth measurement. By using low-resolution SPAD sensors and active encoded illumination, such as two- or three-dimensional fringe patterns, the system captures images that allow for high-resolution depth information. The use of high-speed illuminators, like digital micromirror devices (DMD) or micro-electromechanical systems (MEMS) projectors, enhances the effectiveness of the eye tracking technology.
