3D Display Image Rotation for User Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D display devices require users to manually search through guidelines to understand device functions, making it inconvenient to locate specific information or adjust image settings, and users often depart from the optimal viewing spot, leading to suboptimal viewing experiences.
Innovation Solution
A 3D display device equipped with a measurement unit to track user location and a processor that adjusts image orientation, size, and position based on user movement, ensuring the user remains within an optimal viewing range by rotating or resizing the image when they stray from the sweet spot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image is maintained in a fixed position, then the display structure is simple, but users cannot view the content when they depart from the sweet spot
Solution Approach 1:
The patent implements dynamic image adjustment by rotating and resizing the displayed image based on the user's real-time position relative to the sweet spot. The processor continuously monitors user location and automatically adjusts image orientation and scale, transforming a static display system into an adaptive one that maintains optimal viewing conditions without requiring manual intervention or complex mechanical adjustments.
Solution Approach 2:
The system employs feedback mechanisms where the measurement unit detects user position and provides this information to the processor, which then adjusts the image display accordingly. This closed-loop control ensures the image remains optimally positioned for viewing even as users move, resolving the contradiction between fixed simplicity and adaptive versatility.
2Ease of operation
If manual guidelines are provided, then the device structure is simple, but users spend excessive time searching and studying to use the device
Solution Approach 1:
The system provides self-service functionality by automatically detecting user position and adjusting the display without requiring users to consult manuals or navigate complex settings. The measurement unit and processor work together to autonomously optimize the viewing experience, eliminating the need for users to invest time in studying device operations while maintaining simple device architecture.
3Adaptability or versatility
If the image is rotated to track user movement, then viewing experience is optimized, but the control system becomes more complex
Solution Approach 1:
The patent replaces complex mechanical rotation systems with electronic/image processing solutions. Instead of physically rotating the display hardware, the system uses software-based image rotation and transformation techniques controlled by the processor, achieving the same visual effect with simpler electronic control rather than mechanical mechanisms.

AI summary
A device and a method for controlling the same are disclosed, in which a user may control a 3D display device more conveniently and exactly. The 3D display device comprises a 3D display unit a measurement unit configured to obtain location information indicating a location of a user located in front of the 3D display unit, and a processor configured to control the 3D display unit and the measurement unit, wherein the processor obtains a first angle, which is a horizontal angle between the 3D display unit and the user, by using the location information, maintains an image displayed on the 3D display unit if the first angle is within a preset first angle range, and rotates the image displayed on the 3D display unit based on a vertical axis of the image and in a left or right direction according to the first angle if the first angle departs from the preset first angle range.
