Unified Document ID for Multi-Sheet Handwriting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems fail to effectively unify and manage handwritten information across multiple sheets scanned by a digital pen, particularly when the handwriting spans multiple sheets in a sequential manner, leading to difficulties in identifying and organizing the information as a cohesive document.
Innovation Solution
An information processing apparatus comprising a receiver, detector, and unifier module that identifies sheet identification information, detects sequential scanning operations, and unifies the information across multiple sheets, creating a unified document ID and storing the data as a single document, even when handwriting spans multiple sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handwritten information is scanned across multiple sheets separately, then each sheet can be processed independently, but the information cannot be unified as a single document
Solution Approach 1:
The patent merges information from multiple sheets by detecting sequential scanning operations and unifying the scanned data into a single document. The unifier component combines image data, handwriting recognition results, and metadata from multiple sheets while maintaining their sequential relationships, thereby preserving document coherence while allowing independent processing of each sheet during scanning.
Solution Approach 2:
The patent introduces an intermediary unified document structure that acts as a container for multiple sheet information. This unified document includes a document ID, metadata, and references to individual sheet data, serving as a mediator that links separately processed sheets into a cohesive whole without requiring simultaneous processing of all sheets.
2Productivity
If sequential sheet groups are automatically unified, then document organization is improved, but system complexity increases
Solution Approach 1:
The patent applies preliminary action by embedding sheet identification information (such as sequence numbers or identifiers) into each sheet during the scanning process. This allows the system to automatically detect sequential relationships and perform unification based on pre-established markers, reducing the complexity of real-time analysis while improving document organization efficiency.
Solution Approach 2:
The unification system performs self-service by automatically detecting sequential sheet groups through embedded identification information and unifying them without requiring manual intervention. The system autonomously determines which sheets belong together based on the detection results and unifies them accordingly, simplifying the overall process while maintaining high productivity.
3Measurement precision
If sheet identification information is embedded in information images, then sheet tracking is improved, but printing complexity increases
Solution Approach 1:
The patent uses a universal information image format that serves multiple functions: it contains both the original information content and embedded sheet identification information. This multi-functional approach allows the same printing process to produce both the document content and the tracking markers, avoiding the need for separate identification elements and reducing printing complexity while maintaining high sheet identification accuracy.

AI summary
An information processing apparatus includes a receiver that receives sheet identification information included in information images printed onto sheets scanned by a scanner, a detector that detects that a scanning operation by the scanner is an operation indicating that a plurality of sheets are a sequential sheet group, and a unifier that, when the detector detects an operation indicating the sequential sheet group, unifies information corresponding to the plurality of sheets that is respectively indicated by the plurality of sheet identification information received by the receiver during the scanning operation.
