Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual reality (VR) equipment experiences poor user experience due to complete switching between virtual and real-world perspectives, disrupting immersive experiences, especially during activities like drinking or using mobile phones.
Innovation Solution
A local perspective method in VR equipment that identifies user hand actions to trigger a local perspective function, allowing selective display of real-world scenes within a defined area in the virtual scene, using hand gestures to determine the perspective display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional see-through method is used, then the user can see the real world through the transparent portion of the AR glass, but the user cannot see a specific area (e.g., iris) of another user clearly because the real world image is also transmitted through the same transparent portion
Solution Approach 1:
The transparent portion of the AR glass is divided into a first area (for see-through function) and a second area (for iris recognition). This segmentation allows different regions to serve different functions, enabling the system to maintain see-through capability while simultaneously providing clear iris recognition in the designated area.
Solution Approach 2:
The patent applies local quality by making the second area have different optical properties than the first area. The second area is configured to block or filter the real world image while allowing iris light to pass through, creating a localized region with enhanced iris recognition capability without affecting the overall see-through function of the AR glass.
2Loss of information
If the transparent portion blocks the real world image to see another user's iris clearly, then iris recognition is improved, but the see-through function is lost
Solution Approach 1:
The transparent portion is segmented into distinct functional areas where the second area is optimized for iris recognition by blocking real world images, while the first area maintains full see-through capability. This spatial segmentation resolves the contradiction by allowing both functions to coexist in different regions.
Solution Approach 2:
Different regions of the transparent portion are赋予 different optical characteristics. The second area has properties that selectively block real world light while transmitting iris light, creating a localized zone for enhanced iris recognition without compromising the overall visibility of the real world through the first area.
3Loss of information
If the entire AR glass is made opaque for iris recognition, then another user's iris can be seen clearly, but the user cannot see the real world
Solution Approach 1:
Instead of making the entire AR glass opaque, the patent segments it into a first area for see-through and a second area for iris recognition. This partial segmentation maintains overall visibility of the real world while providing a dedicated zone for clear iris recognition.
Solution Approach 2:
The patent applies local quality by creating a specific region (second area) with enhanced iris recognition properties while the rest of the AR glass (first area) maintains its transparent, see-through properties. This localized approach allows iris recognition improvement without sacrificing real world visibility.

Enhances user experience by enabling seamless interaction with the real world within the virtual environment without interrupting immersion, applicable to various scenarios and improving usability.
Implementation Method 1
a light emitter that transmits light to a specific area (e.g., an iris) of another user through a transparent portion of the augmented reality glass
Implementation Method 2
an image sensor that receives light reflected from the other user's iris to thereby receive an image of the iris

AI summary
Disclosed in the present application are a local see-through method and apparatus for a virtual reality device, and a virtual reality device. The method comprises: recognizing a hand action of a user; if the hand action of the user satisfies a preset triggering action, triggering a local see-through function of a virtual reality device; and under the local see-through function, determining a local see-through display region in a virtual scene according to the position of the hand action of the user so as to display a real scene in the local see-through display region. According to the local see-through method for a virtual reality device of the present application, the range of a region to be displayed in a see-through manner can be determined in combination with the hand action of the user, and compared with a conventional global see-through solution, the method is applicable to more and richer usage scenarios, and can also greatly improve the user experience.
