Marker-Based Content Positioning Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces lack convenience in content switching and positioning, as they often require complex detection processes and multiple markers for different content types, leading to increased computational costs and reduced user experience.
Innovation Solution
An information processing apparatus that uses two distinct markers, one for content determination and another for display position determination, allowing for efficient switching and positioning of content images on a display screen, with the second marker being common across multiple contents to simplify detection and reduce computational load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple markers are used for different content types, then content identification accuracy is improved, but device complexity and computational cost increase
Solution Approach 1:
The patent divides the marker system into two functional segments: a first marker for content identification and a second marker for display position determination. This segmentation allows each marker type to serve a specific purpose, reducing the complexity of processing while maintaining accurate content identification. The system processes these markers in separate determination steps, improving computational efficiency.
Solution Approach 2:
The second marker serves multiple functions: it determines display position and can be used across different content types. By making the second marker universal for position determination regardless of content type, the system reduces the total number of unique markers needed while maintaining precise control over content display positioning.
2Manufacturing precision
If complex detection processes are used for content switching, then content positioning precision is improved, but processing time increases
Solution Approach 1:
The detection process is segmented into two independent determination steps: first determining content based on the first marker, then determining display position based on the second marker. This segmentation allows parallel processing and reduces the computational burden on any single step, thereby decreasing overall processing time while maintaining positioning precision.
Solution Approach 2:
The second marker acts as an intermediary element that specifically mediates the display position determination without interfering with content identification. By introducing this dedicated intermediary marker for position purposes, the system achieves precise positioning through a simplified, dedicated detection process rather than a complex multi-purpose detection system.
3Measurement precision
If multiple markers are used for content determination, then content switching accuracy is improved, but ease of operation decreases
Solution Approach 1:
The patent segments the marker functions so that the first marker handles content identification and the second marker handles display position. This segmentation simplifies the user interface by clearly separating the functions, making it easier for users to understand and operate the system without confusion about which marker serves which purpose.
Solution Approach 2:
The second marker is designed as a universal position determination marker that works across all content types. This universality simplifies operation because users don't need to learn different marker conventions for different content types - the same second marker approach applies consistently throughout the system.

AI summary
An information processing apparatus (2000) includes a first determination unit (2020), a second determination unit (2040), and a display control unit (2060). The first determination unit (2020) detects a first marker (10) from a captured image (30), and determines content corresponding to the detected first marker (10). The second determination unit (2040) detects a second marker (20) from the captured image (30), and determines a display position of a content image (40) in a display screen on the basis of the detected second marker (20). The display control unit (2060) displays the content image (40) at the determined display position in the display screen.
