Floating 3D Image Display With Gaze-Tracked Vertical Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices for floating 3D images suffer from a narrow vertical viewing angle, causing portions of the image to be cut off depending on the user's viewing angle, and lack effective user guidance when the angle exceeds the vertical movement range.
Innovation Solution
Incorporating a display with a 3D plate and a camera to track user gaze, a processor controls the floating image region's movement based on gaze tracking, ensuring it remains within the user's vertical viewing angle by displaying guide images and adjusting the image display area when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a floating 3D display uses a transparent optical material such as a micromirror array, then a floating image can be projected onto space, but the viewing angle becomes narrow in the vertical direction causing image cutoff
Solution Approach 1:
The patent implements dynamic adjustment of the floating image vertical position based on detected user viewing angles. The system continuously monitors the viewing angle and regenerates the floating image at different vertical positions to ensure the complete image remains within the narrow viewing angle range, preventing cutoff while maintaining stable floating display functionality
Solution Approach 2:
The system employs feedback mechanisms by detecting the user's viewing angle and using this information to control the vertical position of the floating image. The detected viewing angle serves as feedback to the image regeneration process, allowing the system to automatically adjust and optimize the display position for each user's specific viewing conditions
2Area of stationary object
If the display area is increased to show the complete floating image, then image completeness improves, but the viewing angle limitation causes portions to be cut off for users at different heights
Solution Approach 1:
The patent changes the vertical position parameter of the floating image based on detected viewing angles. By dynamically adjusting this parameter, the system ensures that the complete floating image remains within the visible range for users at different heights and viewing angles, maintaining both image completeness and viewing comfort without requiring physical display area expansion
3Ease of operation
If gaze tracking and image regeneration are implemented to maintain complete image visibility, then viewing comfort improves, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical adjustment systems with software-based image regeneration. Instead of physically moving or adjusting the display hardware to accommodate different viewing angles, the system uses computational methods to regenerate the floating image at appropriate vertical positions, significantly reducing mechanical complexity while maintaining viewing comfort
Solution Approach 2:
The system creates regenerated copies of the floating image at different vertical positions based on detected viewing angles. This copying approach allows the same image content to be displayed multiple times at different positions, ensuring complete visibility for various users without requiring complex hardware modifications
