Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Setting up multiple displays for a three-dimensional viewing experience is tedious and time-consuming, especially when precise positioning of each display is required to render accurate left and right eye images.
Innovation Solution
A system that automatically discovers the location and orientation of each monitor within an ensemble by using cameras to capture encoded emblems, processing their attributes to compute transformation matrices for spatially consistent image rendering across multiple displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple displays are arranged to work together for 3D viewing, then the viewing experience is enhanced, but the setup process becomes tedious and time-consuming
Solution Approach 1:
The system automatically discovers the arrangement of multiple displays by having each display capture and share images of encoded emblems visible on other displays. The computer system then automatically calculates positions and orientations, eliminating the need for manual configuration and reducing setup time while maintaining enhanced 3D viewing capabilities.
2Measurement precision
If precise positioning of each display is required for accurate 3D rendering, then image accuracy is improved, but the complexity of setup increases
Solution Approach 1:
The system replaces manual mechanical positioning and measurement with an automated optical detection system. Cameras capture images of encoded emblems on each display, and computer processing automatically calculates precise positions and orientations, substituting complex manual alignment procedures with automated image processing and mathematical computation.
Solution Approach 2:
Encoded emblems are introduced as intermediary elements that facilitate automatic discovery of display arrangements. These emblems contain unique identifiers and are captured by cameras, serving as mediators between the physical display positions and the digital processing system, enabling automatic calculation of spatial relationships without direct manual measurement.
3Manufacturing precision
If manual configuration of display positions and orientations is performed, then spatial accuracy can be achieved, but the process becomes very technical and time-consuming
Solution Approach 1:
Each display automatically participates in the configuration process by capturing images of encoded emblems on other displays and sharing them with the computer system. The system then automatically processes these images to calculate positions and orientations, enabling self-configuration without requiring technical expertise or manual intervention for spatial calibration.

AI summary
Multiple electronic displays are arranged to define an ensemble of the user's choosing. The processor generates and displays a uniquely encoded emblem encoding a unique identifier for that display. A camera captures at least one image of the ensemble so that the encoded emblem for each display is captured. The captured images are then processed to extract the following attributes: a) unique identifier of the display; b) position of the encoded emblem relative to the reference coordinate system; and c) pointing direction of the encoded emblem relative to the reference coordinate system. The processor collectively processes the attributes for each of the emblem images to compute for each display a transformation matrix that selects a portion of the image data for display on that monitor and performs pointing direction correction so that the information presented on that display appears spatially consistent with the information presented on the other displays.
