Real-Time Handwriting Recognition With Rich Text Attribute Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices convert handwriting inputs into text without considering the attributes and characteristics of the writing input, requiring users to manually modify text attributes after conversion, and do not provide real-time recognition results.
Innovation Solution
An electronic device with a touch screen and processor that performs real-time handwriting recognition, applies identified attributes and characteristics to the text, and presents a preview of the recognition result before replacing the handwriting input with rich text.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional handwriting recognition converts writing input into text without considering writing attributes, then the conversion process is simple and fast, but the text attributes cannot reflect the original writing characteristics requiring post-conversion modification
Solution Approach 1:
The system performs preliminary extraction of writing attributes (color, thickness, brush type) during the handwriting recognition process itself, before text conversion is completed. This allows the attributes to be preserved and applied to the resulting text automatically, eliminating the need for post-conversion modification while maintaining simple operation flow
Solution Approach 2:
The patent introduces an intermediary mechanism that bridges the handwriting input and text output by extracting and mapping writing attributes to text attributes. This intermediary layer preserves the essential characteristics of the handwriting (color, thickness, brush type) and translates them into corresponding text formatting, preventing loss of information while maintaining conversion simplicity
2Extent of automation
If handwriting recognition is performed automatically after writing completion, then the system operates autonomously, but the user cannot view recognition results until after completing the writing process
Solution Approach 1:
The system performs handwriting recognition in real-time during the writing process itself, rather than waiting for writing completion. This preliminary action allows the user to view recognition results immediately as they write, eliminating waiting time while maintaining automated operation. The system processes handwriting attributes and converts to text continuously, providing immediate feedback
Solution Approach 2:
The patent implements real-time feedback by displaying the handwriting recognition result on the touch screen during the writing process. The user can see the converted text and attribute applications (color, thickness, brush type) appearing as they write, providing immediate verification and correction opportunities while maintaining automated processing flow
3Manufacturing precision
If the system applies all handwriting attributes to text conversion, then the text reflects complete writing characteristics, but the processing complexity increases
Solution Approach 1:
The system applies different levels of attribute processing to different aspects of the handwriting input. It extracts and applies color, thickness, and brush type attributes selectively based on their importance and detectability. This local quality approach ensures accurate text attribute mapping for the most significant handwriting characteristics while avoiding unnecessary processing complexity for less critical or difficult-to-detect attributes
Data Source
AI summary
Disclosed is an electronic device including a touch screen, a memory and a processor, wherein the memory stores instructions that, when executed, cause the at least one processor to detect a handwriting recognition request for a first handwriting input while displaying the first handwriting input on the touch screen, in response to detecting the handwriting recognition request, perform the handwriting recognition for the first handwriting input to identify a text corresponding to the first handwriting input, apply at least one color of the first handwriting input identified based on the handwriting recognition to the text, present a first rich text to which the at least one color has been applied, adjacent to the first handwriting input, and in response to a request for replacing the first handwriting input with the first rich text, replace the first handwriting input with the first rich text.
