GUI Display Control for Accurate Gaze-Guided Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems struggle with accurately directing the user's line of vision to the desired area due to discrepancies between detected object positions and actual object positions, especially when graphical user interface (GUI) images are displayed outside the user's intended viewing area, leading to potential misalignment and discomfort.
Innovation Solution
An electronic apparatus with a display control unit that adjusts the position and visibility of GUI images based on detected user viewpoints and object positions, using a first and second detecting unit to ensure alignment and minimize overlap, and employs threshold values to manage visibility and tracking reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GUI images are displayed in areas other than the user's desired viewing area, then information display capability is improved, but line of vision detection accuracy deteriorates
Solution Approach 1:
The patent dynamically adjusts the display position and visibility of GUI images based on detected line of vision position. When the line of vision is directed toward a desired area, the GUI image is displayed in a position corresponding to that area. When the line of vision shifts, the GUI image position is adjusted or visibility is reduced, ensuring continuous alignment with the user's actual viewing focus and maintaining detection accuracy.
Solution Approach 2:
The patent applies different display strategies to different regions of the display device. The display control unit determines whether to display the GUI image in the first area (desired viewing area) or second area (other area) based on line of vision detection results. This localized adaptation ensures that GUI information is displayed optimally in the region where the user is actually looking, rather than using a fixed display position.
2Extent of automation
If line of vision information is used for object detection, then automation is improved, but detection accuracy deteriorates due to GUI interference
Solution Approach 1:
The patent implements a feedback loop where the display control unit continuously monitors line of vision detection results and adjusts GUI image display accordingly. The system detects the user's line of vision position, determines the desired viewing area, and feeds this information back to adjust the GUI image position and visibility. This closed-loop control ensures that automation continues while minimizing GUI interference with detection accuracy.
Solution Approach 2:
The system dynamically adjusts the GUI image display state based on real-time line of vision detection. When detection accuracy is compromised by GUI presence, the system automatically adjusts the GUI position or reduces its visibility, allowing automated object detection to proceed with high accuracy while maintaining user information access when appropriate.

AI summary
An electronic apparatus includes: a display control unit configured to display an input image, a first GUI image, and a second GUI image at a display; a first detecting unit configured to detect a position of a predetermined object in the input image; and a second detecting unit configured to detect a viewpoint of a user in the input image, wherein the display control unit displays the first GUI image in a position corresponding to the position of the predetermined object detected by the first detecting unit and the second GUI image in a position corresponding to the viewpoint detected by the second detecting unit, and in a case where the first GUI image and the second GUI image overlap, the display control unit makes the second GUI image less noticeable than in a case where the first GUI image and the second GUI image do not overlap.
