Latest Patents

One of his latest patents is titled "Method and apparatus for calibration-free eye tracking." This invention provides a method and apparatus for eye gaze tracking in human or animal subjects without the need for calibration of cameras or specific measurements of eye geometries. The method involves tracking a user's eye gaze at a surface, object, or visual scene by analyzing images to find glints or reflections in the user's eyes.

Another significant patent by Cheng is "Method and apparatus for calibration-free eye tracking using multiple glints or surface reflections." This invention utilizes an uncalibrated camera to acquire video images of the subject's eyes, along with off-axis illuminator markers that reflect on the corneal surface of the subject's eyes as glints. These glints help determine the distance between the point of gaze and the corresponding marker, enhancing the accuracy of eye tracking.
