AI Technical Summary

Problems solved by technology

However, the current research on naked-eye augmented reality still faces many challenges, such as needing to be attached to a carrier such as a mobile phone or a camera to generate a virtual-real fusion image instead of naked-eye observation; on the other hand, the robustness is not enough. Can produce jitter, destroying the user's realism experience

Embodiment 1

[0051] A method for realizing a penetrating screen system based on eye tracker tracking, comprising the following steps:

[0052] The system is a monocular system, and the eye positions mentioned below are based on the left eye.

[0053] 1). Establish a standard coordinate system, such as figure 1 As shown, the standard coordinate system constructed by the system takes a certain default eye position as the origin, sets a position of the monocular as the origin, and the line connecting the origin and the midpoint of the screen is the z-axis, and the origin can be The plane intersecting with the screen is at the midpoint of the screen, the x-axis is a straight line in the horizontal direction, the y-axis is a straight line in the vertical direction, and the plane formed by the x-axis and the y-axis is parallel to the notebook screen;

[0054] 2). Place the Tobii eye tracker in front of the screen, use the Tobii eye tracker to obtain the position of the single eye, and convert t...

Abstract

The invention relates to a method for realizing a penetrating screen system based on eye tracker tracking, which belongs to the field of augmented reality technology, and comprises the following steps: establish a standard coordinate system, use Tobii eye tracker to obtain the position of a single eye, and convert the Tobii coordinate system to The standard coordinate system is then converted to the Unity coordinate system, and the real screen and eyes are mapped to the Unity coordinate system. After a series of transformations and calibrations, it is aligned with the camera in the virtual scene, so that users can interact with the system using only their eyes. Effect.

Description

technical field [0001] The invention relates to a method for realizing a penetrating screen system based on eye tracker tracking, and belongs to the technical field of augmented reality. Background technique [0002] The history of eye trackers dates back to the 18th century. Since Wells used images (ghost images) to describe the movement of the eyes in 1792, human beings have not stopped studying the eyes. Now, with the invention of various eye trackers, computers can recognize human eyes. The status of human eye tracking and related issues: AReview, [Wade, N., and Tatler , B.W. The moving tablet of the eye: The origins of modern eye movement research. Oxford University Press, 2005.]. [0003] Tobii Eye Tracker is a new low-cost binocular eye tracker. The system is designed for natural eye-gaze interaction, requires no continuous recalibration, and allows for moderate head movements. And the official also designed a set of SDK (SDK, foreign language full name: Software ...
