Aerial Image Display Control for Face-Based Privacy Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-contact displays in facilities like retail stores and government offices face issues with user privacy, as multiple users may want to prevent others from peeking at sensitive information displayed on the screens.
Innovation Solution
A control system that uses sensors to detect user faces and adjusts the height, position, and orientation of aerial image formations on non-contact displays to ensure only the intended user can easily view specific screens, while making it difficult for others to see.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the aerial image formation is displayed at a fixed position and orientation, then the display is simple to implement, but users cannot prevent others from peeping at the screen
Solution Approach 1:
The patent implements dynamic adjustment of the aerial image formation's position and orientation based on the detected user's face position. The display parameters are no longer fixed but change dynamically according to user location, preventing peeping while maintaining simplicity in the underlying mechanism.
Solution Approach 2:
The system uses a camera to detect the user's face position and provides feedback to the control unit, which then adjusts the aerial image formation accordingly. This closed-loop feedback mechanism enables automatic peeping prevention without requiring complex manual control.
2Object-affected harmful factors
If the aerial image formation is adjusted based on user face position, then peeping is suppressed, but the device becomes more complex
Solution Approach 1:
The control unit serves multiple functions: it controls the aerial image formation display, processes camera input for face detection, and adjusts display parameters based on detected position. This multi-functionality reduces the need for separate dedicated components, managing complexity while achieving peeping prevention.
Solution Approach 2:
The system automatically detects the user's face position and self-adjusts the aerial image formation without requiring manual intervention. This self-service capability simplifies the user interface while maintaining the sophistication needed for peeping prevention.
3Adaptability or versatility
If the display position is fixed, then the manufacturing is simple, but the adaptability to different users is poor
Solution Approach 1:
The patent changes the display parameters (position, orientation, size) of the aerial image formation based on the detected user's face position. This parameter adjustment approach allows the same hardware to adapt to different users without requiring multiple physical displays or complex mechanical adjustments.

AI summary
A control system comprising: a memory storing instructions; and at least one processor configured to execute the instructions to: detect a face of a person using a sensor; perform control in such a way that when a screen other than a specific screen among a plurality of screens to be displayed on a non-contact display is displayed, an aerial image formation of the non-contact display includes a predetermined height, a predetermined position, a predetermined orientation, and a predetermined size; and perform control to change at least any one of a height, a position, an orientation, and a size of the aerial image formation for displaying the specific screen based on a position of the detected face of the person when the specific screen is displayed.
