Virtual Keyboard Text Replication for Input Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of virtual keyboards on touch screens face difficulties in verifying the accuracy of input characters without tactile feedback, requiring them to shift focus between the virtual keyboard and the application data field, leading to inefficiency.
Innovation Solution
A virtual keyboard system that includes a keyboard data field for echoing characters entered, allowing users to view the input characters without altering their field of view, by presenting the virtual keyboard alongside the application data field and providing immediate visual feedback of the selected or entered characters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual keyboard is used on a touch screen, then input flexibility is improved, but the ability to verify input accuracy deteriorates due to lack of tactile feedback
Solution Approach 1:
The patent implements a feedback mechanism by displaying the entered character in a designated area of the touch screen immediately after the user presses a virtual key. This visual feedback allows users to verify the accuracy of their input without leaving the keyboard interface, resolving the contradiction between input flexibility and verification ease.
Solution Approach 2:
The patent creates a visual copy of the input character at a fixed location on the screen. This copied character serves as immediate feedback to the user, allowing them to verify what was typed without needing tactile feedback from a physical keyboard.
2Adaptability or versatility
If a user uses a virtual keyboard without tactile feedback, then input flexibility is improved, but the time required to verify input accuracy increases
Solution Approach 1:
The system performs preliminary action by displaying the entered character immediately at the keyboard location before the user needs to verify it. This immediate visual feedback eliminates the need for the user to switch their attention to the data field, reducing verification time while maintaining input flexibility.
Solution Approach 2:
The patent provides immediate visual feedback by displaying the entered character in a designated area of the touch screen. This feedback mechanism allows users to verify input accuracy instantly without time-consuming shifts in attention between the keyboard and data field.
3Adaptability or versatility
If a user must shift focus between the virtual keyboard and the data field to verify input, then input flexibility is maintained, but productivity decreases
Solution Approach 1:
The patent merges the feedback function into the keyboard interface itself by displaying the entered character at the keyboard location. This integration eliminates the need to shift focus between separate elements (keyboard and data field), thereby maintaining input flexibility while improving productivity.
Solution Approach 2:
The system provides immediate visual feedback within the keyboard interface, allowing users to verify input without shifting focus to the data field. This feedback mechanism eliminates the productivity loss associated with repeated focus shifts while preserving input flexibility.
Data Source
AI summary
Text that is selected at a virtual keyboard is submitted to and displayed at an application data field another data field, such as a keyboard data field, that can be in closer proximity to the virtual keys used to select the text. Thus, a user does not have to alter their field of view to the application data field to determine what was submitted to the application data field.
