Aerial Floating Image Display Privacy Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerial floating image display systems face safety concerns due to the risk of unauthorized individuals peeking at the displayed information, compromising the security and privacy of users, especially when others are present behind the user performing touch operations.
Innovation Solution
The system incorporates a retroreflector and imager to detect multiple individuals in the captured image, triggering a notification to the user when someone is peeking, thereby enhancing the safety and security of the aerial floating image display by alerting the user and potentially adjusting the display settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the aerial floating image display apparatus displays information in the air, then the ease of operation and user interaction is improved, but the safety and privacy protection deteriorates due to unauthorized peeking
Solution Approach 1:
The system implements a monitoring mechanism using an imager to detect the presence of multiple persons. When unauthorized viewing is detected (multiple persons present), the system provides feedback by displaying a notification message to alert the user. This feedback loop enables the system to respond dynamically to security threats while maintaining the aerial display functionality.
Solution Approach 2:
The patent introduces an intermediary monitoring system consisting of the imager and control unit that stands between the user and potential unauthorized viewers. This intermediary detects the presence of multiple persons and mediates the situation by triggering safety notifications, thereby protecting user privacy without interfering with the core aerial display operation.
2Object-affected harmful factors
If a monitoring system is added to detect multiple persons, then the safety and privacy protection is improved, but the device complexity increases
Solution Approach 1:
The imager serves multiple functions: it captures images for both the aerial floating image display and the security monitoring task. By making the imager multi-functional, the system achieves privacy protection capabilities without adding dedicated separate hardware components, thereby minimizing the increase in device complexity.
Solution Approach 2:
The system uses its own existing resources (the imager already present for display purposes) to perform the additional security monitoring function. The control unit analyzes images captured by the imager to detect multiple persons, enabling the system to monitor itself and provide security without requiring external monitoring equipment.

AI summary
An aerial floating image display apparatus includes a display apparatus configured to generate an image, a retroreflector configured to reflect image light from the display apparatus, and an imager, and if a plurality of persons appear in a captured image generated by the imager, the aerial floating image display apparatus displays, as an aerial floating image, information for notifying a user of the aerial floating image display apparatus of being peeked.
