Latest Patents

One of Hao Qin's latest patents involves sensor fusion eye tracking. This technology utilizes a device equipped with one or more processors, image sensors, and an illumination source. The process begins by detecting a first attribute of an eye based on pixel differences associated with various wavelengths of light in an initial image of the eye. Subsequently, a first location related to this attribute is determined within a three-dimensional (3D) coordinate system, utilizing depth information from a depth sensor. Additionally, the technology detects a second attribute of the eye based on a glint from the illumination source reflecting off the cornea. This leads to the determination of a second location in the 3D coordinate system, allowing for the calculation of gaze direction based on both locations.
