Head-Mounted Display Gaze Control for Dynamic Image Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display devices require manual head movement to switch display modes, lacking the ability to dynamically adjust images based on user gaze and head orientation.
Innovation Solution
A control device that detects the user's line of sight and head orientation to determine the most and second-most recognized images, adjusting their display positions to minimize the distance between them, enhancing dynamic image adjustment without manual head movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display unit displays multiple images requiring user to move head to switch modes, then the device can provide diverse display content, but the user burden increases due to manual head movement required
Solution Approach 1:
The system automatically determines which images to display and their positions based on detection results without requiring user head movement. The control device autonomously selects the first and second images and adjusts their display positions, making the system self-serve the user's needs without manual intervention.
Solution Approach 2:
The system uses detection units to monitor user line of sight and head orientation, then feeds this information back to the control device. Based on this feedback, the control device automatically adjusts display positions and selects images, creating a closed-loop system that adapts to user behavior without requiring explicit commands.
2Adaptability or versatility
If the display position of second image is far from first image, then the display layout is flexible, but the user must move head more to switch between images
Solution Approach 1:
The display positions of images are dynamically adjusted based on real-time detection results. The control device calculates optimal positions for the first and second images, moving them closer together when needed to reduce user head movement, while maintaining layout flexibility when the situation allows.
Solution Approach 2:
The system changes the spatial parameters (display positions) of images based on detection data. By adjusting the coordinates and distances between images dynamically, the system optimizes the viewing experience while maintaining adaptability in different display scenarios.

AI summary
A control device includes a determination unit that determines an image visually recognized by a user among a plurality of images displayed by an image display unit based on at least one of the line of sight of the user and the orientation of the head of the user, a setting unit that sets, as a first image, an image having the highest number of determination times that an image has been determined as an image visually recognized by the user among the plurality of images displayed by the image display unit, and sets, as a second image, an image having the second highest number of determination times after the first image, and a display control unit that changes a display position of the second image so that a display distance between the first image and the second image being displayed becomes shorter than a preset distance.
