Marker-Based Projection System for Dynamic Image Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems for work procedures, such as cooking, lack user control over the display position of projected images, making it difficult for users to identify the contents and arrange markers correctly, which can lead to overlapping images and reduced work efficiency.
Innovation Solution
A display method and system that use markers with two-dimensional codes on a projection surface, allowing the imaging device to capture the markers' positions and corresponding images, and project images in arrangements matching the markers' layout, enabling users to intuitively designate image positions and improve workflow by correlating markers with objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display position of the image is determined in advance by the system, then the system operation is simplified, but the user cannot control where the image is displayed, making it difficult to identify image contents when items are arranged on the workbench
Solution Approach 1:
The patent introduces markers as intermediary objects that mediate between the user and the projection system. Users place markers on the workbench to indicate desired image positions, and the system detects these markers to determine where to project images. This intermediary mechanism enables user control without requiring complex direct interaction with the projection system.
Solution Approach 2:
The patent replaces manual adjustment of projection positions with an automated detection system. Instead of requiring users to mechanically adjust projector position or angles, the system uses imaging devices to detect marker positions and automatically calculates appropriate projection positions, substituting mechanical control with optical detection and computational processing.
2Quantity of substance
If multiple images are projected on the workbench without user control, then the system can display multiple information, but images may overlap with items or each other, reducing work efficiency
Solution Approach 1:
The patent implements dynamic image positioning where the projection positions are not fixed but adapt based on the detected marker arrangements. The system continuously monitors marker positions and adjusts image placements accordingly, allowing multiple images to be displayed without overlapping while maintaining flexibility to accommodate different work scenarios.
3Ease of operation
If the system automatically determines image display positions, then the operation is simple, but users cannot intuitively designate image positions corresponding to specific objects or areas
Solution Approach 1:
The patent divides the workbench into discrete positioning zones using markers. Instead of requiring users to specify continuous coordinates or positions, the system segments the workspace into marker-defined locations, making position designation intuitive and discrete. Users simply place markers where they want images displayed, and the system detects these segmented positions automatically.

AI summary
A display method includes imaging a captured image containing a first marker placed on a surface and a second marker placed on the surface, and displaying a first image corresponding to the first marker and a second image corresponding to the second marker in an arrangement corresponding to an arrangement of the first marker and the second marker in the captured image on the surface.
