Title: Innovations by Tiesheng Wang in Gaze Tracking Technology
Introduction
Tiesheng Wang is a notable inventor based in Danderyd, Sweden. He has made significant contributions to the field of gaze tracking technology, holding a total of 3 patents. His work focuses on enhancing the accuracy and functionality of gaze tracking systems, particularly in head-mounted devices.
Latest Patents
One of Tiesheng Wang's latest patents is titled "Gaze tracking using mapping of pupil center position." This invention involves capturing images of an eye with a camera and estimating the position of the pupil center in these images. The gaze data obtained indicates the gaze point or direction of the eye at the time of image capture. A calibrated mapping is created to correlate the pupil center positions in the images to gaze points on a surface or gaze directions. This process can be performed using a head-mounted display (HMD).
Another significant patent is "Detecting relocation of a head-mounted device." In this invention, images of the eye are captured at various time instances by a camera integrated into a head-mounted device. The positions of the corneal curvature center and pupil center are estimated from these images. By determining lines through these estimated positions, the system computes the eye center's position over time. This allows for the detection of the head-mounted device's relocation relative to the user's head.
