Display Panel Viewer Authorization for Private Collaborative Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices fail to differentiate between authorized and unauthorized viewers of confidential information on display panels, often mistakenly preventing intended collaborative viewing due to shoulder surfing detection.
Innovation Solution
An electronic device with an image sensor and controller that monitors the environment, detects interactions and actions between viewers, determining authorization based on these interactions, and adjusts display visibility accordingly to protect confidential information while allowing collaborative viewing when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device uses shoulder surfing detection protocols to prevent unauthorized viewing, then information privacy is protected, but authorized collaborative viewing is mistakenly prevented
Solution Approach 1:
The system continuously monitors viewer presence and interactions, then adjusts display visibility based on detected authorization patterns. The feedback loop detects when a second viewer appears, analyzes their behavior patterns over time, and dynamically adjusts between protecting privacy and enabling collaboration based on the accumulated evidence of authorization.
Solution Approach 2:
The display visibility is made dynamic rather than static. The system transitions between different visibility states (fully visible, partially obscured, fully obscured) based on real-time detection of viewer interactions and accumulated authorization patterns, allowing the system to adapt its behavior to current viewing conditions.
2Reliability
If the electronic device monitors and detects second viewers, then unauthorized viewing is prevented, but intended collaborative activities are obstructed
Solution Approach 1:
The system automatically distinguishes between authorized and unauthorized viewers through behavioral analysis without requiring manual intervention. The electronic device serves itself by detecting interaction patterns, determining authorization status, and adjusting display visibility autonomously, eliminating the need for users to manually configure privacy settings for each collaborative session.
Solution Approach 2:
The system introduces an intermediary analysis layer between the detection of a second viewer and the obstruction of viewing. Instead of immediately blocking the second viewer, the system analyzes interaction patterns as an intermediary step to determine whether the viewer is authorized, allowing legitimate collaboration to proceed while blocking unauthorized access.
3Reliability
If the electronic device reduces display visibility upon detecting a second viewer, then information privacy is maintained, but authorized viewers are unnecessarily blocked
Solution Approach 1:
The system performs preliminary monitoring and analysis of viewer interactions before taking action to obstruct viewing. By detecting and analyzing interaction patterns in advance, the system can determine authorization status before reducing display visibility, preventing unnecessary blocking of authorized collaborative viewing sessions.
Solution Approach 2:
The system uses continuous feedback from monitoring viewer interactions to make informed decisions about display visibility. The feedback mechanism tracks interaction patterns over time and only triggers visibility reduction when unauthorized viewing is confirmed, avoiding unnecessary interruptions to authorized collaborative activities.

AI summary
Example electronic devices are disclosed. In some examples, the electronic device includes a display panel, an image sensor, and a controller coupled to the image sensor. The controller is to use the image sensor to detect an interaction between a first viewer of the display panel and a second viewer of the display panel. In addition, the controller is to determine whether the second viewer is authorized to view information presented on the display panel based on the interaction. Further, the controller is to adjust a presentation of the information on the display panel based on the determination.
