Latest Patents

Congshan Wan holds a patent for "Eye tracker illumination through a waveguide." This invention is designed for a see-through waveguide-based head-mounted display (HMD) device that projects holographic virtual images within the user's field of view (FOV). The patent describes a method where a single pixel or group of pixels is illuminated at specific locations on the display. This illumination is reflected from the user's eyes and captured by sensors in an eye tracker. The eye tracker utilizes real-time image analysis to interpret the reflected light, known as 'glints,' to determine the user's gaze point and calculate eye movement, location, and orientation. The technology incorporates a negative lens functionality to maintain a fixed focal depth for virtual images, allowing the illuminated pixels to serve as virtual glint sources for the eye tracker sensor.
