Gaze-Controlled AR Display Management for Limited Screen Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable devices for augmented reality (AR) services face challenges in providing user-friendly information display due to limited screen space, making it difficult for users to easily access desired AR information.
Innovation Solution
A portable device equipped with a gaze detection unit, display unit, and processor that detects user gaze to determine a target object, identifies associated and non-associated AR images, and dynamically manages their display based on the object's movement, ensuring only relevant AR information is displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple AR images are displayed simultaneously on a limited screen, then information completeness is improved, but user ability to easily acquire desired information deteriorates
Solution Approach 1:
The patent implements dynamic display management where AR images are automatically adjusted based on detected gaze direction. The system transitions from static simultaneous display of multiple AR images to dynamic selective display, where only gaze-associated AR images are prominently shown while others are dimmed or hidden, resolving the contradiction between information completeness and accessibility
Solution Approach 2:
The patent employs gaze detection feedback to control AR image display. The gaze detection unit continuously monitors user eye direction and provides feedback to the processor, which then adjusts the display of AR images accordingly. This closed-loop feedback mechanism ensures that the displayed information always matches user attention, improving both information accessibility and completeness
2Device complexity
If AR images are displayed without gaze detection, then device complexity is reduced, but user experience and information relevance deteriorate
Solution Approach 1:
The patent implements a self-service mechanism where the system automatically identifies and prioritizes relevant AR images based on detected gaze direction without requiring manual user input. The gaze detection unit and processor work together to autonomously manage display content, providing enhanced user experience while maintaining relatively simple operation
Solution Approach 2:
The patent integrates gaze detection functionality into the existing AR display system, allowing the same device to perform both traditional display functions and gaze-based adaptive display. This multi-functionality approach enhances user experience without requiring completely separate systems, balancing complexity and performance

AI summary
A method for controlling a portable device is disclosed. The method includes displaying a plurality of augmented reality (AR) images, detecting a gaze of a user, determining a target object based on the gaze of the user, identifying an associated AR image that is associated with the target object and a non-associated AR image that is not associated with the target object from the plural AR images, and maintaining display of the associated AR image and terminating display of the non-associated AR image when the target object is a moving object.
