Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for inputting location information using a pen-type digital input device are not intuitive for operators, differing significantly from conventional non-digital techniques, making it difficult for users to learn and perform the operation effectively.
Innovation Solution
An information input apparatus and method that presents an input format with a location input field and a location association information field, allowing users to input location information by tracing a figure or symbol on a map, with a unit to recognize and associate the symbol with its corresponding location, generating input result data including the location and associated information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location information is input using numeric coordinate values or conventional digital input methods, then input precision and data accuracy are improved, but operator ease of use and learnability deteriorate due to significant difference from conventional paper-based methods
Solution Approach 1:
The patent applies the copying principle by replicating the familiar paper-based input format on a digital screen. The system displays a map image and allows operators to draw figures or write text using a digital pen, exactly as they would on paper. The drawn elements are then recognized and converted into structured location data, thereby copying the intuitive paper-based interaction while achieving digital precision and automation.
2Ease of operation
If the input method closely follows conventional paper-based techniques, then operator ease of use and learnability are improved, but automation capability and data processing efficiency deteriorate
Solution Approach 1:
The patent introduces an intermediary element - a recognition unit - that bridges the gap between the simple drawing action and the complex data processing. The operator's drawing is first recognized and converted into structured data (coordinate information, figure type, associated text) by this intermediary unit, which then processes the information automatically. This intermediary layer enables both intuitive operator interaction and sophisticated automated processing.
3Measurement precision
If the system requires tracing complex patterns or icons to input location, then input precision is improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent applies segmentation by breaking down the location input process into distinct, manageable components: (1) drawing a simple figure to indicate location, (2) optionally writing associated text nearby, and (3) the system automatically recognizing and processing these separate elements. This segmentation allows the system to handle complex location identification through simple, discrete user actions rather than requiring mastery of complex tracing patterns.

AI summary
The present invention achieves an information input apparatus for inputting position location information by an input using a pen-type input device configured to acquire handwriting data expressed as a trace of coordinate positions. The information input apparatus includes: an input format presenting unit for presenting an input format for interpreting the handwriting data, the input format having a location input field used to input a figure or a symbol in such a manner that a location in a drawing is identifiable; a location information acquisition unit for recognizing the figure or the symbol inputted in the location input field and for acquiring information on the location of the figure or the symbol inputted in the location input field, on the basis of the handwriting data of the figure or symbol inputted in the location input field.
