Automatic Viewing Angle Control for Confidential Display Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices pose challenges in protecting sensitive information from inadvertent or surreptitious viewing due to their wide viewing angles, as users often forget to manually adjust privacy filters when displaying confidential content.
Innovation Solution
A system that automatically changes the viewing angle of a display device based on detected confidentiality indicators, using an electronically-controlled privacy filter and an auditing application to analyze content for confidential attributes, codes, or keywords, thereby reducing the viewing angle when sensitive information is displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a privacy filter is attached to the display, then the viewing angle becomes smaller and information protection is improved, but the device complexity increases and the filter must be manually removed to restore the original viewing angle
Solution Approach 1:
The patent applies the dynamics principle by making the privacy filter electronically controllable and automatically adjustable. The system dynamically changes the viewing angle based on real-time detection of confidential information, eliminating the need for manual attachment and removal of physical filters. The privacy filter transitions from a static physical component to a dynamic electronically-controlled element that can be adjusted on demand.
Solution Approach 2:
The system implements self-service through automatic detection of confidential information and autonomous adjustment of the privacy filter. The auditing application monitors content and triggers viewing angle changes without user intervention, allowing the system to protect itself automatically. This eliminates the need for users to manually manage privacy filters while displaying sensitive information.
2Object-affected harmful factors
If the viewing angle is reduced to protect confidential information, then information protection is improved, but the ease of operation deteriorates as users must manually change the viewing angle
Solution Approach 1:
The system performs self-service by automatically detecting confidential information through the auditing application and autonomously adjusting the privacy filter settings. This eliminates the need for user intervention in changing viewing angles, maintaining ease of operation while ensuring information protection is actively enforced based on content analysis.
Solution Approach 2:
The system implements feedback through the auditing application that continuously monitors displayed content for confidential information. When confidential content is detected, the system provides feedback by automatically adjusting the viewing angle to protect the information. This closed-loop feedback mechanism ensures appropriate privacy protection without requiring user awareness or action.
3Device complexity
If manual privacy filter adjustment is required, then the device complexity is reduced, but the reliability of information protection deteriorates as users may forget to change the viewing angle
Solution Approach 1:
The system ensures reliable information protection through self-service automation. The auditing application continuously monitors content and automatically triggers privacy filter adjustments when confidential information is detected, eliminating human forgetfulness. The system protects itself autonomously, ensuring consistent enforcement of privacy measures regardless of user attention or memory.
Solution Approach 2:
The system takes preliminary action by proactively detecting confidential information before it can be viewed by unauthorized persons. The auditing application scans content in advance and pre-adjusts the privacy filter settings, ensuring protection is already in place before the confidential information becomes vulnerable to viewing from inappropriate angles.

AI summary
A system of automatically changing a viewing angle of a display device based on a determination of content confidentiality includes a display device, an auditing application, and a privacy filter control. The auditing application is configured to analyze content to be displayed on the display device for confidentiality indicators. The privacy filter control is configured to automatically change a current viewing angle of the display device from a first viewing angle to a second viewing angle that is less than the first viewing angle when the content includes at least one confidentiality indicator and the current viewing angle of the display device is the first viewing angle.
