J7EF Gaze maintains its advantages of first-person perspective and hands-free, also enhances the Human-Computer Interface (HCI). The eye-tracking technology traces the direction, speed, distance of dynamic eye movements, gaze target as well as change of pupil radius. It also offers a consistent experience for a broader range of the population with different inter-pupillary distance (IPD) and eye refraction. Besides, with the integration of multiple sensors, the coordination among head motion, gesture control and eye tracking adapt to natural human biology. The “Head-Hand-Eye” HCI are more intuitive, precise and direct, allowing the users to get the “insights” into the Metaverse. It can be used for the filed of manufacturing, exhibition, and medical to facilitate industrial upgrading and digital transformation.
