Light guide component and manufacturing method, eye tracking module and method, video glasses

Abstract

Embodiments of the present invention provide a light guide component and its manufacturing method, an eye tracking module and method, and video glasses, wherein the light guide component is arranged in the eye tracking module and includes: a first substrate and a second substrate oppositely arranged , a first electrode disposed on the first substrate, a second electrode disposed on the second substrate, and at least one liquid crystal structure disposed between the first electrode and the second electrode, the liquid crystal structure comprising liquid crystal molecules; wherein the first The electrode and the second electrode are used to control the deflection direction of the liquid crystal molecules through the applied voltage, so that the light directed to the light guide component meeting the threshold condition is emitted along a predetermined direction. In the embodiment of the present invention, a light guide component is provided in the eye tracking module, which not only reduces the occupied volume of the eye tracking module, meets the overall thinning requirement of the eye tracking module, but also realizes the real-time controllability of the eye tracking module. , saving resources.

Description

technical field [0001] The embodiments of the present invention relate to the field of human-computer interaction technology, and in particular to a light guide component and its manufacturing method, an eye tracking module and its method, and video glasses. Background technique [0002] Eye tracking technology is a technology that uses mechanical, electronic, optical and other detection methods to obtain the subject's current "gaze direction". With the rapid development of computer vision, artificial intelligence technology and digital technology, eye tracking technology has become a current hot research field and has a wide range of applications in the field of human-computer interaction, for example, it can be applied to virtual reality, augmented reality, vehicle assisted driving, user Experience, cognitive impairment diagnosis and other fields. [0003] The inventors have found through research that the existing eye-tracking modules used to implement eye-tracking techn...

Problems solved by technology

[0003] The inventors have found through research that the existing eye-tracking modules used to implement eye-tracking technology will keep tracking the eyeballs once they start working, and will continue to track even when eye-tracking is not needed, making the existing eye-tracking modules unable to Real-time controllable, resulting in a waste of resources. In addition, the existing eye tracking module occupies a large volume, which cannot meet the overall thinning requirements of the eye tracking module.
