Gaze-Driven Display Mode Switching for AR Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality systems fail to seamlessly integrate virtual and real-world information display, particularly in wearable terminals, limiting user interaction and efficiency in tasks that require simultaneous observation of both virtual and real-world elements.
Innovation Solution
A display system comprising a wearable terminal with a first display and an external unit, both equipped with controllers that detect the user's gaze and adjust display formats accordingly, allowing synchronized display of information between the two units, enabling intuitive and hands-free operation by switching between virtual and real-world views based on user attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the wearable terminal displays virtual information superimposed on reality space, then the user can observe virtual objects, but the user cannot simultaneously observe both virtual and real-world elements clearly
Solution Approach 1:
The patent implements dynamic switching between augmented reality display mode and ordinary display mode based on detected user gaze direction. When the user looks at the wearable terminal, the display switches to ordinary mode for clear observation of virtual information. When the user looks at the real-world object, the display switches to AR mode for seamless integration. This dynamic adaptation resolves the contradiction by providing clear observation clarity when needed and information integration when appropriate.
Solution Approach 2:
The system changes display parameters (transparency, brightness, content) based on the user's gaze state. By detecting whether the user is looking at the wearable terminal or the real-world object, the system adjusts display parameters to optimize either information integration or observation clarity accordingly, resolving the technical contradiction between these two opposing requirements.
2Ease of operation
If the user focuses on observing the real-world object, then the user can maintain awareness of the environment, but the user cannot simultaneously interact with virtual information
Solution Approach 1:
The patent enables dynamic interaction modes based on user gaze. When the user looks at the real-world object, the system maintains AR display for environmental awareness while allowing virtual information interaction through gaze detection. When the user looks at the wearable terminal, the system switches to ordinary display mode for detailed virtual information interaction. This resolves the contradiction by enabling hands-free operation while maintaining access to virtual information through contextual switching.
3Loss of information
If the wearable terminal provides continuous virtual information display, then the user has constant access to data, but the user experience becomes complex and less intuitive
Solution Approach 1:
The patent implements dynamic display mode switching based on user gaze detection. The system provides continuous information availability through AR display when the user looks at the real world, and switches to ordinary display mode when the user looks at the terminal for detailed interaction. This contextual switching maintains information availability while preserving user interaction intuitiveness by providing the appropriate display mode at the right moment.
Solution Approach 2:
The system automatically detects user gaze direction and switches display modes without requiring explicit user commands. This self-service mechanism resolves the contradiction by intelligently adapting the display to user needs, maintaining information availability while keeping interaction intuitive and automatic.

AI summary
A display system, that is capable of displaying substantially the same content on a wearable terminal that is attached to the head of a user and has a first display section, and on a unit other than the wearable terminal that has a second display, comprises a controller that determines an object the user is gazing at, and a display controller that controls update of display states based on the object that has been determined, when an image, that has been displayed on the second display, is displayed on the first display.
