Replacement Gesture for Text String Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current text entry methods on computing devices, such as smartphones and tablets, are inefficient for replacing misspelled or mistyped words, requiring users to delete characters or retype them, which slows down the text input process.
Innovation Solution
Implementing a replacement gesture on a presence-sensitive display that involves a first swipe in a leftward direction followed by a swipe in a rightward direction to select a suggested character string from a list, allowing users to quickly replace the incorrect text with a more accurate option.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users delete characters or retype them to replace misspelled words, then text replacement accuracy is improved, but text entry speed deteriorates
Solution Approach 1:
The system performs preliminary analysis of the typed text to identify potential misspelled words and generates a list of suggested corrections before the user needs to replace them. This allows the user to simply select from pre-computed options rather than manually deleting and retyping, thus maintaining accuracy while improving speed.
Solution Approach 2:
The system creates copies of the misspelled text and presents multiple corrected versions (suggested character strings) for user selection. Instead of requiring the user to manually reconstruct the correct text, the system provides pre-generated alternative versions that can be quickly inserted by gesture selection.
2Measurement precision
If users manually delete and retype characters to replace text, then replacement precision is improved, but time consumption increases
Solution Approach 1:
The system performs preliminary analysis of the typed text to identify potential misspelled words and generates a list of suggested corrections before the user needs to replace them. This allows the user to simply select from pre-computed options rather than manually deleting and retyping, thus maintaining accuracy while improving speed.
Solution Approach 2:
The system introduces an intermediary gesture mechanism that mediates between the user's intent to replace text and the actual replacement action. The leftward then rightward swipe gesture serves as an efficient intermediary command that triggers automatic text replacement with suggested corrections, eliminating the need for time-consuming manual deletion and retyping while maintaining precision through user confirmation.
3Ease of operation
If a simple gesture is used for text replacement, then ease of operation is improved, but gesture recognition accuracy deteriorates
Solution Approach 1:
The replacement gesture is segmented into two distinct directional components: a leftward swipe followed by a rightward swipe. This segmentation allows the system to clearly distinguish the replacement gesture from other gestures while maintaining relative simplicity. The directional breakdown provides unambiguous recognition cues without requiring overly complex gesture sequences.

AI summary
A computing device includes at least one processor and at least one module. The module may determine and output for display a list of one or more suggested character strings based on a first input received at a presence-sensitive display. The module may further receive an indication of a second user input detected at the presence-sensitive display. The module may further determine whether the second user input includes a replacement gesture, wherein the replacement gesture includes a first gesture in a substantially leftward direction and a second gesture in a substantially rightward direction. Responsive to determining that the received gesture input includes the replacement gesture, the module may output for display in place of the displayed text, a character string chosen from the list of one or more suggested character strings.
