Touch Screen Text Correction via Offset Enlarged View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in accurately editing text on small touch screens due to the small size of text characters and the challenge of precisely positioning the cursor for corrections, which existing solutions like Android's cursor movement and magnifying glass features do not adequately address.
Innovation Solution
Providing an enlarged view of individual words or phrases on a touch screen, offset from the input entry field, allowing users to easily edit errant inputs by receiving an indication of the word to be modified and accepting editing inputs directly in the enlarged view or the original text entry field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If text input entry is provided on a small touch screen, then the device can be compact and portable, but the text characters become too small for accurate editing and cursor positioning
Solution Approach 1:
The patent introduces a popup window that displays an enlarged view of the selected word or phrase in a separate dimension (popup layer) above the main text entry field. This allows the text to be displayed at a larger size for accurate editing without increasing the physical device dimensions, effectively adding a spatial layer to resolve the contradiction between compact size and editing accuracy.
Solution Approach 2:
The patent segments the text editing function into two distinct views: the original text entry field and an enlarged popup view of the selected word/phrase. This segmentation allows users to work with the full text context in the main field while obtaining an enlarged, easier-to-edit view in the popup window, resolving the contradiction between small screen size and editing precision.
2Ease of operation
If the touch screen size is increased to improve text editing accuracy, then text characters become larger and easier to edit, but the device becomes less portable and more cumbersome
Solution Approach 1:
Instead of increasing the physical screen size, the patent utilizes the vertical dimension by creating a popup window that overlays the main text entry field. This popup displays the selected text at a larger size, providing accurate editing capability without expanding the device's physical footprint, thus maintaining portability while improving editing accuracy.
Solution Approach 2:
The patent creates a copied, enlarged version of the selected word or phrase in the popup window. This copy allows users to edit the text with enhanced visibility and precision without requiring a larger physical display, thereby avoiding the need to increase device size while still achieving accurate text editing.
3Ease of operation
If existing solutions like cursor movement or magnifying glass features are used, then some text positioning capability is provided, but they do not adequately address the challenge of precise cursor positioning for corrections
Solution Approach 1:
The patent moves the cursor positioning task from the constrained two-dimensional text entry field to an enlarged popup window. In this expanded view, the same physical distance represents a larger number of pixels, making it easier for users to precisely position the cursor at the correct location for text corrections, thereby improving measurement precision without adding device complexity.
Solution Approach 2:
The patent performs preliminary action by automatically displaying the selected word or phrase in an enlarged popup window before the user attempts to edit it. This pre-enlargement provides immediate visual context and makes cursor positioning more precise from the outset, rather than requiring users to manually adjust zoom levels or navigate through multiple interface steps.

AI summary
An embodiment provides a method, including: receiving, at a processor, an indication of an input including a word; providing, on a touch screen, an enlarged view of the input indicated, wherein the enlarged view is off set from an input entry field on the touch screen; and accepting, using a processor, editing input that modifies the word. Other embodiments are described and claimed.
