Character Correction UI for Display Apparatus Input Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face frequent misrecognition and misinput issues when entering characters using voice recognition or remote controllers, leading to user inconvenience in correcting incorrectly entered characters.
Innovation Solution
A display apparatus and character correcting method that provides user interfaces for editing characters, allowing users to easily correct errors through motion, pointing device, or voice input by displaying delete and insert options, with recommended word suggestions, enabling convenient correction of typographic errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If voice recognition or remote controller is used for character input, then input speed and convenience are improved, but misrecognition and misinput errors increase
Solution Approach 1:
The system displays the input sentence in a character input window and provides real-time feedback by showing selected words and characters, allowing users to verify input accuracy and correct errors immediately. The UI presents the current input state and correction options, enabling users to detect and fix misrecognition or misinput errors without re-entering the entire sentence.
2Reliability
If characters are corrected one by one using remote controller, then input accuracy is improved, but operation time and user inconvenience increase
Solution Approach 1:
The system automatically detects and highlights selected words or characters that may contain errors before the user needs to correct them. By pre-identifying potential issues and presenting correction options in advance, the system reduces the time and effort required for correction compared to manual character-by-character editing.
Solution Approach 2:
The UI acts as an intermediary between the voice/remote input and the final output, providing a buffer where users can review, select, and correct characters. This intermediate display layer allows efficient correction operations through motion or pointing device input, reducing the time penalty for achieving high input accuracy.
3Manufacturing precision
If detailed character editing UI is provided, then correction precision is improved, but device complexity increases
Solution Approach 1:
The UI is segmented into functional components: a character input window displaying the sentence, a selection mechanism for words or characters, and correction options (delete item, insert item). This segmentation allows the system to provide detailed correction capabilities while maintaining a manageable and intuitive interface structure.
Solution Approach 2:
The detailed editing UI is activated locally only when a word or character is selected for correction. Instead of presenting all editing options continuously, the system displays correction tools (delete, insert, recommended words) only when needed, reducing perceived complexity while maintaining high correction precision when required.

AI summary
A character correcting method of a display apparatus includes displaying a sentence including at least one word in a character input window; displaying, if one of the at least one word is selected, a first user interface (UI) in which the at least one selected word is displayed by a character unit; and, displaying, if one of a plurality of characters displayed in the first UI is selected, a second UI around the selected character, the second UI is configured to edit the selected character.
