Video Preview on Home Screen Reducing Operation Complexity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing video preview methods on electronic devices require users to perform multiple operations to view video-related content, leading to low usage efficiency as the preview is only accessible after opening the video application and navigating through various screens.
Innovation Solution
A video preview method that allows electronic devices with touchscreens to receive user operations, display a preview video on the leftmost screen or home screen when a video application icon is detected, and continue playing the preview even when switching between screens, optimizing user interaction and reducing operational complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the video application is opened to access video preview content, then the video preview can be viewed, but the user must perform multiple operations (opening application, navigating screens) which reduces usage efficiency
Solution Approach 1:
The system performs preliminary actions by pre-loading and caching video preview content in the background before the user needs to access it. When the user opens the video application or navigates to a screen, the preview content is already ready to be displayed immediately, eliminating the need for the user to perform multiple operations to access the content.
Solution Approach 2:
The system introduces an intermediary mechanism (system-level preview service) that acts as a mediator between the user and the video application. This intermediary service manages the video preview content independently of the user's direct interaction with the application, allowing the preview to be displayed without requiring the user to open or navigate through the full application interface.
2Productivity
If the video application is opened to access preview content, then the preview can be viewed, but the operations required greatly reduce device usage efficiency
Solution Approach 1:
The system performs preliminary actions by pre-loading and caching video preview content in the background before the user needs to access it. When the user opens the video application or navigates to a screen, the preview content is already ready to be displayed immediately, eliminating the need for the user to perform multiple operations to access the content.
Solution Approach 2:
The system maintains continuous useful action by keeping the video preview service running in the background, continuously managing and updating preview content without requiring the user to restart or re-navigate. The preview content remains accessible and ready for immediate display, ensuring continuous availability without operational interruptions.

AI summary
A video preview method includes receiving, by an electronic device, a first operation, displaying, by the electronic device, a first screen on a touchscreen of the electronic device in response to the first operation, where the first screen is a page of a home screen or a leftmost screen, obtaining, by the electronic device, a first preview video corresponding to a first video application when the first screen includes an identifier of the first video application, displaying, by the electronic device, a first video preview window in the first screen, and playing, by the electronic device, the first preview video in the first video preview window.
