Display Apparatus Stroke Component Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies require burdensome operations for users to repeatedly draw or select frequently used drawings, lacking efficient methods to recall and display previously created content during meetings or conferences.
Innovation Solution
A display apparatus that divides user-drawn content into components, allowing for the storage and retrieval of whole drawings by comparing input strokes with stored components, enabling the display of similar drawings based on similarity criteria, thereby reducing the need for repetitive drawing or selection processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually draw or select frequently used drawings each time, then the display apparatus can show the desired content, but the operation becomes burdensome and time-consuming
Solution Approach 1:
The system performs preliminary actions by automatically dividing drawings into components and storing them in advance. When a user needs a drawing, the system has already prepared the component data, enabling quick retrieval by simply inputting a keyword rather than manually drawing or searching through stored drawings each time.
Solution Approach 2:
The system creates copies of drawing components by dividing original drawings into smaller reusable elements and storing them separately. These component copies can be efficiently retrieved and recombined based on keyword input, eliminating the need to handle complete drawings manually.
2Productivity
If the system stores complete drawings as single units, then storage is simple, but retrieval requires burdensome manual drawing or selection operations
Solution Approach 1:
The system segments complete drawings into smaller drawing components automatically. This segmentation enables efficient keyword-based retrieval by allowing the system to search within specific components rather than searching through entire drawings or requiring manual user input of complete drawing sequences.
Solution Approach 2:
The system introduces drawing components as an intermediary between complete drawings and user queries. Instead of directly matching user input against stored drawings, the system uses components as intermediate elements that can be independently searched, matched, and recombined based on keywords.
3Measurement precision
If users input detailed stroke data to retrieve drawings, then retrieval accuracy improves, but the operation becomes more complex and time-consuming
Solution Approach 1:
The system extracts essential features from complete drawings by dividing them into components and storing component-specific data. This extraction allows the system to achieve precise matching by comparing keywords against component characteristics rather than requiring users to input detailed stroke information for entire drawings.

AI summary
A display apparatus includes circuitry to receive an input of a plurality of strokes representing a drawing that includes one or more drawing components including a first drawing component. The plurality of strokes is divided under a predetermined condition to obtain the one or more drawing components. The circuitry stores, in a memory, each of the one or more drawing components and drawing data representing the drawing. The circuitry displays, on a display screen, in response to receiving an input of a second drawing component, the drawing represented by the drawing data based on the first drawing component and the second drawing component.
