AR Apparatus Private Display via Screen Capture and Unlock Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for secure and private display of confidential content on terminal devices in public places, as existing technologies fail to effectively prevent unauthorized viewing by others.
Innovation Solution
An Augmented Reality (AR) apparatus communicates with a terminal device, determines if it is unlocked by capturing and comparing images, and then displays the image data only if the device is unlocked, adjusting the image display based on distance and size to project it within the terminal device's imaging region, thereby ensuring private viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If image data is displayed on the terminal device screen, then the content is visible to the user, but anyone nearby can view the confidential content
Solution Approach 1:
The patent introduces an AR apparatus as an intermediary device between the terminal device and the user's eyes. Instead of displaying content directly on the terminal screen where anyone can see it, the AR apparatus captures the screen content and projects it through augmented reality lenses, creating a private viewing channel that only the user can access.
Solution Approach 2:
The patent transitions the display from the two-dimensional terminal screen to a three-dimensional augmented reality space. By projecting the image data through AR lenses into the user's field of view, the content is rendered in a private visual dimension that overlays on the real world, preventing others from viewing it.
2Reliability
If the AR apparatus displays image data without checking unlock status, then the display function is simple and fast, but confidential content may be displayed when the terminal is locked
Solution Approach 1:
The patent performs the unlock status check as a preliminary action before allowing any image data to be displayed. The AR apparatus captures an image of the terminal screen and compares it with a pre-stored target image to verify whether the terminal has been unlocked. This preliminary security verification ensures that confidential content is never displayed when the terminal is locked.
Solution Approach 2:
The patent implements a feedback mechanism where the AR apparatus continuously monitors the terminal's unlock status by comparing captured images with stored reference images. Based on this feedback, the system dynamically controls whether to display the image data, creating a secure feedback loop that prevents unauthorized viewing.
3Manufacturing precision
If the AR apparatus displays image data at fixed size and position, then the display processing is simple, but the image cannot be properly projected within the terminal device's imaging region
Solution Approach 1:
The patent makes the image display parameters dynamic by calculating the imaging region based on the actual distance between the AR apparatus and the terminal device. The system determines the appropriate image size and position within the imaging region according to real-time distance measurements, allowing the image to be properly projected regardless of the specific distance configuration.
Solution Approach 2:
The patent changes the display parameters (image size, position, and scaling) based on the measured distance between the AR apparatus and the terminal device. By adjusting these parameters dynamically, the system ensures that the image data is correctly projected within the imaging region while maintaining simplicity in the overall display processing.
