AR Wearable Extended Display for Seamless Lecturer Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality (AR) display scenarios, particularly during presentations that utilize projected PPTs, lecturers often need to turn their back to the audience to view the presentation screen, disrupting the presentation and interaction due to the lack of a seamless dual-screen display solution.
Innovation Solution
An AR display device and method that configures an AR wearable device as an extended display of a terminal, enabling a dual-screen heterogeneous display mode by processing and transmitting streaming media data from a computing device to the wearable device, allowing it to display image data in real-time, thereby preventing the need for the lecturer to face away from the audience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lecturer uses a projection PPT to give a presentation, then the presentation content can be displayed, but the lecturer needs to turn his back to the audience to view the PPT page, affecting the presentation effect and interaction
Solution Approach 1:
The patent introduces an AR wearable device as an intermediary between the lecturer and the PPT content. The device receives image data from the terminal (displaying the PPT) and presents it to the lecturer through the AR interface, allowing the lecturer to view the PPT without turning away from the audience.
Solution Approach 2:
The patent transitions the PPT viewing experience from a two-dimensional screen to a three-dimensional AR space. By projecting the PPT content into the AR environment, the lecturer can view the content in a spatial overlay that does not require physical reorientation, thus maintaining engagement with the audience.
2Loss of information
If the lecturer turns back to view the PPT on the projection screen, then the PPT content can be viewed, but the interaction between the lecturer and the audience is disrupted
Solution Approach 1:
The AR wearable device serves as a mediator that delivers PPT content directly to the lecturer's field of view. This eliminates the need for the lecturer to physically turn around, thereby maintaining continuous interaction with the audience while still accessing all necessary PPT information.
Solution Approach 2:
The AR wearable device performs multiple functions: it displays PPT content, provides real-time feedback, and maintains the lecturer's visual connection with the audience. This multi-functionality resolves the contradiction by integrating content delivery and interaction maintenance into a single device.
3Adaptability or versatility
If the terminal transmits image data to the AR wearable device, then the dual-screen heterogeneous display mode is achieved, but data transmission stability and speed must be ensured
Solution Approach 1:
The patent implements a feedback mechanism where the terminal and AR wearable device continuously monitor and adjust data transmission parameters. This ensures stable and fast data transmission by dynamically adapting to network conditions and device performance, maintaining reliability while achieving versatile dual-screen display functionality.
