Solution Overview

Problem

Existing input display devices require users to perform handwriting input for each input field individually, leading to inefficiencies in filling out forms with multiple input fields.

Innovation Solution

An input display device that groups stroke data from handwriting input across multiple fields into character strings, conducts character recognition, and displays recognized characters at the corresponding input fields, allowing for collective handwriting input without needing to input each character string individually.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If character recognition is conducted for each input field individually, then character recognition accuracy is maintained, but user input efficiency deteriorates

Engineering Contradiction:
Improveuser input efficiencyVSAvoidinput operation complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent merges multiple individual character recognition operations into a single batch processing operation. Stroke data from multiple input fields are collected and grouped together, then character recognition is performed once on the entire group rather than separately for each field. This combining approach resolves the contradiction by improving efficiency through batch processing while maintaining recognition accuracy through proper grouping of stroke data by spatial position and temporal sequence.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of time

If handwriting input is performed for each input field separately, then input precision is maintained, but time consumption increases

Engineering Contradiction:
Improvetime for handwriting inputVSAvoidcharacter recognition precision
Core Design Contradiction:
Loss of timeVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by collecting and grouping stroke data from multiple input fields before performing character recognition. The system preliminarily organizes the handwriting input data by identifying spatial relationships between strokes and temporal sequences, preparing the data in advance for batch processing. This preliminary grouping ensures that when character recognition is performed, the precision is maintained because the strokes are properly associated with their corresponding characters before recognition begins.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If batch character recognition is performed across multiple fields, then input efficiency is improved, but difficulty in detecting and measuring individual field inputs increases

Engineering Contradiction:
Improvehandwriting input efficiencyVSAvoidposition correlation detection
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies segmentation by dividing the batch of stroke data into distinct groups based on spatial position and temporal characteristics. Each group of strokes is associated with a specific input field through detection of the writing position relative to field boundaries. This segmentation allows the system to perform batch processing for efficiency while simultaneously maintaining the ability to detect and measure individual field inputs accurately, as each segmented group can be independently identified and processed.

Inventive Principle:
Principle #1Segmentation

AI summary

An input display device includes a display unit that displays a screen for handwriting input on an input screen including a plurality of input fields, a stroke data processing unit that groups stroke data which is input to a capture screen by handwriting into stroke data representing characters to generate grouped stroke data as grouping stroke data, a character recognition unit that conducts character recognition on the grouping stroke data to convert the grouping stroke data into at least one recognized character, and a control processing unit that displays the at least one recognized character at the plurality of input fields of the input screen correlated with positions, at which handwriting input was performed, in the screen for handwriting input.
