AR Glasses Virtual Screen Positioning via Image Center Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Notebooks with single display screens are insufficient for executing multiple programs, requiring external physical expansion screens that increase weight and reduce mobility, necessitating a solution for adding an extra display without compromising portability.
Innovation Solution
An augmented reality system comprising portable electronic devices with a positioning assembly and augmented reality glasses that capture images to determine the image center point position, controlling the glasses to display virtual screens extending from the device's sides when the center point moves beyond the assembly, eliminating the need for external physical screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a physical expansion screen is externally attached to the notebook computer, then the display capability is improved, but the weight increases and mobility is reduced
Solution Approach 1:
The patent uses virtual screen images projected through augmented reality glasses to create a visual copy of an extended display area, rather than using a physical screen. The image capturing module captures the display module image, and the processing circuit generates virtual screen images that appear to extend from the original display, providing expanded display capability without physical expansion.
Solution Approach 2:
The patent replaces the mechanical/physical screen attachment system with an optical system. Instead of physically attaching a second screen to the notebook, the system uses the image capturing module, processing circuit, and augmented reality glasses to project virtual images, substituting mechanical expansion with optical projection.
2Area of stationary object
If a physical expansion screen is externally attached to the notebook computer, then the display capability is improved, but the device complexity increases
Solution Approach 1:
The augmented reality glasses serve multiple functions: they capture images of the display module, process the images to determine center point positions, generate virtual screen images, and project them to the user's field of view. This multi-functional approach consolidates what would otherwise require separate components into a single wearable device.
Solution Approach 2:
The processing circuit acts as an intermediary that receives the display module image from the image capturing module, processes it to determine the center point position relative to positioning assembly, and generates the appropriate virtual screen image parameters. This intermediary processing layer simplifies the overall system architecture by centralizing the control logic.
3Area of stationary object
If external physical hardware is added to expand the screen, then the display capability is improved, but the mobility is reduced
Solution Approach 1:
The patent transitions from a two-dimensional physical screen attachment problem to a three-dimensional virtual image projection solution. The virtual screens are positioned in spatial relationships around the user's field of view, with the first virtual screen extending from a first side and the second virtual screen extending from a second side, creating an immersive multi-dimensional display experience without physical bulk.

AI summary
An augmented reality system includes a portable electronic device, a pair of augmented reality glasses, and a processing circuit. The portable electronic device has a display module and a positioning assembly, and the positioning assembly is disposed on the display module. The augmented reality glasses include an image capture module, and the image capture module is configured to capture at least one image of the display module. The processing circuit is configured to determine a position of an image center point of the at least one image relative to the positioning assembly according to the at least one image. When the processing circuit determines that the position of the image center point moves from the display module across the positioning assembly, the processing circuit controls the augmented reality glasses to display a virtual screen, and the virtual screen extends from a first side of the display module.
