Eye movement tracking device and system based on electromagnetic tracking technology

Abstract

The invention discloses an eye movement tracking device based on an electromagnetic tracking technology and a system thereof, belongs to the field of near-to-eye display, and is characterized in that after a pair of glasses is worn, the picture balance of a display is automatically determined according to the position relationship between three receptors and a glasses frame; the three receptors can ensure that the picture of the display is kept in a horizontal state with the upper border of the glasses frame during wearing, the head movement of a user does not influence the stability of the picture, the picture can be kept in the horizontal state automatically when the wearer changes at any angle, the glasses frame is in a stagnant state by recognizing cornea contact with the transparent display, the intent of a user is judged, a pupil focus point is accurately calculated through a cornea contact transparent display receptor, and a binocular positioning receptor sets a picture distance of a virtual superposition picture through a distance, so that the convergence of the virtual picture and a real picture are in the same distance sensing range, and the distance synchronization of the virtual picture and the real picture is realized.

Description

technical field [0001] The present invention relates to the field of near-eye display, and more specifically, to an eye-tracking device based on electromagnetic tracking technology and a system thereof. Background technique [0002] AR technology is a technology that ingeniously integrates virtual information with the real world. It widely uses various technical means such as multimedia, 3D modeling, real-time tracking and registration, intelligent interaction, and sensing to integrate computer-generated text, images, and 3D Models, music, videos and other virtual information are simulated and applied to the real world, and the two kinds of information complement each other, thereby realizing the "enhancement" of the real world. [0003] Since the beginning of the 20th century, with the development of AR technology, more and more well-known electronics manufacturers have devoted themselves to the research of AR products. For example, Google in the United States and Epson in ...

AI Technical Summary

Problems solved by technology

However, in the field of near-eye display, it is mainly realized by the inward camera. Due to the special structure of the near-eye display, it is difficult for the inward camera to achieve the same effect as the external infrared camera. The accuracy and precision are greatly affected, and it will also affect the wearer's visual impact
