Handwritten Note Management via Character Recognition Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complex operations when trying to access and manage multiple handwritten memos on a touch panel-based information processing apparatus, such as a personal computer, making it difficult to find and view relevant notes.
Innovation Solution
An information processing apparatus with a coordinate input unit, recognition unit, and page/note management unit that manages recognized character data as pages or notes, allowing users to input search conditions and display meta-data linked with the pages or notes, enabling efficient searching and organization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handwritten memos are saved as files in an information processing apparatus, then the data can be stored and preserved, but the user requires complicated operations including opening files and finding intended files when wanting to look at multiple memos simultaneously or highly relevant memos
Solution Approach 1:
The patent segments the memo data into individual character recognition results and organizes them in a structured database format rather than storing as monolithic files. This allows the system to retrieve and display specific characters or portions of memos independently, enabling users to view multiple memos simultaneously without complex file opening operations.
Solution Approach 2:
The patent introduces a character recognition result database as an intermediary between the stored memo data and the user interface. This database layer provides structured access to memo contents, allowing users to search and view memo information without directly manipulating files, thus simplifying the user operation while maintaining data reliability.
2Loss of information
If users want to view multiple memos simultaneously or find highly relevant memos, then information accessibility is improved, but the operation becomes complicated requiring file opening and searching
Solution Approach 1:
The patent performs preliminary character recognition and organizes memo data into a structured database format before user access is needed. This pre-processing creates an organized structure that enables rapid retrieval and simultaneous display of multiple memos or relevant portions, eliminating the need for complex file searching operations at user interaction time.
Solution Approach 2:
The patent transitions from traditional file-based one-dimensional access to a multi-dimensional database structure where memos can be accessed simultaneously through multiple query dimensions (keywords, time, author, etc.). This allows users to retrieve and view multiple relevant memos at once by specifying search criteria, greatly simplifying the operation while improving information accessibility.

AI summary
An information processing apparatus comprising a coordinate input unit for inputting coordinate data series, a recognition unit for recognizing a character based on the coordinate data series inputted, and a page/note management unit for managing a data aggregate of the character recognized as a page, receiving a search condition from a user, and managing one or more page aggregates hit by the condition as notes.
