Video Orientation Detection for Interactive Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video communication technologies face challenges in providing a seamless experience, particularly when sharing and viewing landscape video on mobile devices oriented vertically, which results in black bars and difficulty in viewing due to smaller screen sizes, and lack interactive presentation methods.
Innovation Solution
The system processes and formats video by determining device orientation and region of interest, allowing for vertical cropping and interactive selection of video sources, enabling users to choose how video content is displayed through device orientation and user input, such as tilting or touching the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If landscape video is displayed on a vertically oriented mobile device, then the video can be viewed on the device screen, but large black bars appear on the top and bottom of the screen
Solution Approach 1:
The video display is segmented into multiple regions including a main video area and additional information areas. The video content is divided and presented across different screen zones, allowing the system to eliminate black bars by strategically positioning video segments and supplementary content in available screen real estate.
Solution Approach 2:
The system transitions from traditional full-screen landscape video to a multi-dimensional layout that utilizes vertical screen space effectively. By arranging video content, controls, and information in a hierarchical spatial structure with different zones (main video area, overlay regions, bottom controls), the system maximizes the use of the vertical orientation while maintaining video visibility.
2Adaptability or versatility
If video is displayed on a smaller screen device, then the device portability is maintained, but the video viewing difficulty increases
Solution Approach 1:
Different regions of the screen are assigned different functional qualities and visual characteristics. The main video area uses high-contrast settings optimized for visibility, while overlay regions use semi-transparent backgrounds to preserve video visibility. Controls are positioned in areas with adequate spacing for easy interaction, and important video elements are enhanced with localized adjustments to size, color, or position based on their importance.
3Device complexity
If traditional video presentation is used, then the implementation is simple, but interactive control over video content is lacking
Solution Approach 1:
The video presentation system dynamically adjusts its layout and content based on user interactions and device state. Users can interact with the video by tapping, swiping, or tilting the device, which triggers dynamic responses such as pausing, playing, switching between video sources, or adjusting the region of interest. The interface elements and video content reposition themselves in real-time based on user preferences and context.
