Handwriting Recognition Display System for Multilingual Character String Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems lack the ability to efficiently facilitate communication between speakers of different languages by allowing users to select and convert character strings from one language to another without requiring repeated handwriting input.
Innovation Solution
A display apparatus that displays multiple character string candidates for conversion, allowing users to select and convert handwritten data into a target language, and subsequently reconvert if necessary, using a pen-based input system with associated language settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handwriting recognition converts hand drafted data to character strings directly, then the conversion process is simple, but users cannot select from multiple character string candidates and cannot easily verify translation accuracy
Solution Approach 1:
The system performs preliminary character string conversion to generate multiple candidate translations before final selection. The handwriting recognition unit converts hand drafted data into multiple character string candidates, which are then displayed for user selection, allowing verification and correction of translation accuracy.
Solution Approach 2:
The system provides feedback by displaying multiple character string candidates to the user for selection. The user can review the translation results and select the appropriate character string, creating a feedback loop that ensures translation accuracy before final output.
2Reliability
If the system converts character strings to target language directly without selection capability, then the process is efficient, but users cannot verify or correct translation errors
Solution Approach 1:
The system performs preliminary conversion to generate multiple character string candidates in the target language before final selection. This allows users to verify translation accuracy and correct errors without requiring complete re-conversion from the original hand drafted data.
Solution Approach 2:
The system allows users to discard incorrect translation candidates and recover the correct one by selection. Once a user selects a corrected character string, the system retains this corrected version for subsequent operations, avoiding the need to re-verify the correction.
3Adaptability or versatility
If users need to reconvert character strings after selection, then translation flexibility is maintained, but the overall conversion efficiency decreases
Solution Approach 1:
The system performs preliminary conversion of the selected character string back to the source language character strings, preparing multiple candidate translations in advance. This allows users to quickly switch between different target languages or correction options without performing complete re-conversion operations.
Solution Approach 2:
The system creates copies of the conversion process by generating multiple character string candidates from the same hand drafted data. This allows flexible language conversion without requiring the original handwriting to be rewritten, maintaining both flexibility and efficiency.

AI summary
A display system includes a receiving unit (21) to receive hand drafted data input by an electronic pen; a recognition unit (23) to convert the hand drafted data into a plurality of character string candidates in a recognition language; a storing unit (40) to store, in a memory, association information associating a target language with identification information of the electronic pen, the target language different from the recognition language; a display control unit (24) to display, on a screen, the plurality of character string candidates; and a conversion unit (30) to convert one of the plurality of character string candidates selected by the electronic pen into the target language associated with the identification information of the electronic pen. The display control unit (24) displays a converted character string converted into the target language, and, in response to selection of the converted character string, displays a plurality of character string candidates in the recognition language corresponding to the converted character string.
