HMD Sub-Screen Transparency Control for 360-Degree Live-Stream Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 360-degree live-streams restrict viewers to a single angle, causing them to miss important information if they focus on the background instead of the streamer, necessitating a system to dynamically adjust screen transparency based on the viewer's angle of observation.
Innovation Solution
A display system comprising a content generator, a Head Mounted Display (HMD), and a computing device that adjusts the transparency of a sub-screen by comparing the viewing-angle range with an important-angle range, ensuring that important information remains visible and immersive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional 360-degree live-stream is used, then the immersive environment is provided, but the user can only observe from one specific angle and may lose important information
Solution Approach 1:
The display is segmented into multiple virtual screens (first virtual screen, second virtual screen, third virtual screen) that can be independently positioned and oriented. Each screen displays different content from the 360-degree video feed, allowing users to view multiple angles simultaneously without losing important information.
Solution Approach 2:
The system transitions from a single-angle 2D display to a multi-angle 3D spatial display. By creating virtual screens at different orientations and positions in 3D space, the system allows users to observe the streamer from multiple dimensions simultaneously, solving the information loss problem while maintaining immersion.
2Loss of information
If multiple virtual screens are displayed simultaneously, then important information visibility is improved, but visual interference between screens may occur
Solution Approach 1:
Each virtual screen is assigned a specific transparency level based on its orientation and the user's viewing angle. The transparency of each screen is locally adjusted so that screens showing important content remain clearly visible while other screens have reduced opacity, preventing visual interference while maintaining information visibility.
Solution Approach 2:
The system dynamically changes the transparency parameter of each virtual screen based on the user's head orientation and the importance of the content being displayed. By adjusting this parameter in real-time, the system optimizes information visibility while minimizing visual interference between overlapping screens.
3Loss of information
If screen transparency is dynamically adjusted, then clear visibility of important information is maintained, but system complexity increases
Solution Approach 1:
The system uses feedback from the user's head orientation sensors to automatically adjust the transparency of each virtual screen. This closed-loop control ensures that the most relevant content remains clearly visible while reducing the transparency of less important screens, maintaining information clarity without requiring complex manual adjustments.
Solution Approach 2:
The system automatically determines which content is most important based on the user's viewing direction and automatically adjusts screen transparency accordingly. This self-service approach eliminates the need for complex user interfaces or manual configuration, reducing perceived system complexity while maintaining clear visibility of important information.

AI summary
A display system includes a content generator, an HMD (Head Mounted Display), and a computing device. The content generator generates image/video information. The HMD obtains a viewing-angle range relative to a user. The computing device is coupled to the HMD. The computing device receives the image/video information and the viewing-angle range. The computing device controls the HMD to display a main screen and a sub-screen according to the image/video information. The computing device adjusts the transparency of the sub-screen by comparing the viewing-angle range with an important-angle range.
