Handwritten Data Storage and Transmission via Stroke Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face limitations in storing and transmitting handwritten data due to storage space requirements and lack of conveying user feelings or moods, as they simply display captured input data without context.
Innovation Solution
An electronic device is designed to collect input time information for each stroke of handwritten data, allowing for efficient storage and transmission by converting data into standard character format, and displaying it based on input time to convey user emotions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If handwritten data is stored in typical electronic devices, then the data can be captured and stored, but the storage space required becomes excessively large
Solution Approach 1:
The patent extracts only the essential features of handwritten data (stroke information, input time information) rather than storing the complete raw handwriting data. This selective extraction reduces storage requirements while preserving the core information needed for reconstruction and analysis.
Solution Approach 2:
The patent transforms handwritten data from its original complex form into a simplified parameter-based representation. By converting handwriting into discrete parameters (stroke coordinates, timing data, pressure information), the system achieves efficient storage while maintaining the ability to reconstruct and display the handwriting with its temporal characteristics.
2Quantity of substance
If handwritten data is transmitted in typical electronic devices, then the data can be sent to other devices, but the transmit quota required becomes excessively large
Solution Approach 1:
The patent extracts only the essential features of handwritten data (stroke information, input time information) rather than transmitting the complete raw handwriting data. This selective extraction reduces transmission requirements while preserving the core information needed for reconstruction and analysis.
Solution Approach 2:
The patent transforms handwritten data from its original complex form into a simplified parameter-based representation. By converting handwriting into discrete parameters (stroke coordinates, timing data, pressure information), the system achieves efficient transmission while maintaining the ability to reconstruct and display the handwriting with its temporal characteristics.
3Ease of operation
If handwritten data is simply displayed in typical electronic devices, then the captured data can be shown, but user feelings or moods are not properly conveyed
Solution Approach 1:
The patent collects input time information for each stroke before display, preparing the temporal data in advance. This preliminary collection of timing information enables the display system to reconstruct the handwriting sequence with proper timing, thereby conveying the user's writing speed, pauses, and rhythmic patterns that reflect their feelings and moods.
Solution Approach 2:
The patent introduces dynamic temporal characteristics to the display by utilizing input time information. Instead of static display of handwriting results, the system enables dynamic reconstruction that reflects the original writing process, including variations in stroke timing, pauses between characters, and overall writing rhythm, thereby conveying emotional and contextual information.
