Terminal Device Video Display Orientation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing smart device setups, users face inconvenience when viewing video images captured by smart cameras due to the aspect ratio mismatch between the video image and the screen, requiring frequent touch operations to navigate and resulting in a poor viewing experience.
Innovation Solution
A method and device that utilize an orientation sensor in a terminal device to detect and respond to orientation changes, allowing the video image to automatically slide on the screen, ensuring the entire image is visible without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the video image is compressed to fit the screen in vertical state, then the entire video image can be displayed, but the viewing experience deteriorates due to the need for frequent touch operations
Solution Approach 1:
The patent applies the dynamics principle by making the video image display position changeable based on device orientation. The video image automatically adjusts its position on the screen according to the terminal device's orientation data, allowing the display to adapt dynamically between horizontal and vertical states without requiring user intervention or touch operations.
2Ease of operation
If the video image is enlarged to fill the screen, then the viewing experience improves, but the video image cannot be fully displayed due to aspect ratio mismatch
Solution Approach 1:
The patent applies the dimensionality change principle by utilizing the horizontal dimension of the screen when the device is in horizontal orientation. This allows the full-width video image to be displayed without compression while maintaining aspect ratio, effectively using the additional horizontal space to accommodate the complete video content.
3Ease of operation
If the screen is in vertical state, then the device is easy to hold, but the video image display quality deteriorates due to aspect ratio constraints
Solution Approach 1:
The patent applies the universality principle by making the display system capable of functioning effectively in multiple orientations. The video playback functionality adapts to both horizontal and vertical device states, allowing the same system to provide optimal viewing experience regardless of how the user holds the device, thus achieving multi-functional adaptability.
