Multitask Preview Blur Levels for Mobile Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multitask management interfaces on mobile devices perform blanket blur processing on private application previews, preventing users from viewing any interface, thus failing to meet diverse privacy requirements and resulting in a poor user experience.
Innovation Solution
Implement a method where blur processing is applied differentially to user interfaces based on privacy levels, allowing clear views of non-private windows while protecting private information, and varying the blur intensity for different private windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If blanket blur processing is performed on all private application previews in the multitask management interface, then privacy information is protected, but users cannot preview any interface of the application
Solution Approach 1:
The patent applies local quality by differentiating blur processing based on window privacy attributes. Instead of uniformly blurring all private application previews, the system identifies specific windows marked as private and applies blur only to those windows while leaving other windows of the same application clear. This allows users to preview non-private interfaces while protecting private information, resolving the contradiction between privacy protection and interface preview capability.
2Object-affected harmful factors
If uniform blur processing is applied to all windows of a private application, then privacy is protected, but diversified privacy requirements of users for different windows cannot be met
Solution Approach 1:
The patent segments the application windows into different categories based on privacy attributes. Each window is independently evaluated and assigned a privacy level, allowing differential blur processing. This segmentation enables the system to meet diversified privacy requirements by applying blur only to windows that require protection while allowing users to view other windows clearly, thus enhancing adaptability to different privacy needs.
3Object-affected harmful factors
If blur processing is performed on private application previews, then privacy information is safeguarded, but user experience is degraded due to inability to preview any interface
Solution Approach 1:
The patent preserves interface preview information by applying blur locally only to specific private windows rather than the entire application preview. Users can still view clear previews of non-private windows and understand the application interface layout, while private windows are blurred to protect information. This local approach minimizes information loss while maintaining privacy protection.
Data Source
AI summary
An information display method are disclosed. The method includes: displaying a first multitask management interface, where the first multitask management interface includes a first preview image of a first user interface of a first application; displaying a second user interface of the first application; after switching the second user interface to a background, triggering displaying of a second multitask management interface, where the second multitask management interface includes a second preview image of the second user interface. The first preview image is an image obtained by performing blur processing on a screenshot to a first degree, the second preview image is an image obtained by performing blur processing on a screenshot to a second degree, and the first degree is different from the second degree.
