Software Keyboard Visual Indicators for Home Key Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Software keyboards lack tactile indicators for home keys like 'F' and 'J', making touch typing more difficult compared to hardware keyboards, as physical bumps or ridges cannot be provided.
Innovation Solution
A software keyboard system that displays indicators such as bands, pointing marks, or circles to emphasize specific keys like 'F' and 'J' using a touch-sensitive display, allowing recognition through the peripheral visual field even without direct gaze, with options including horizontal and vertical indicators, different colors, and blinking or size-changing elements.

Engineering Contradiction Analysis
1Ease of operation
If physical bumps or ridges are provided on keyboard keys, then tactile indicators for home keys are available, but this cannot be implemented on software keyboards
Solution Approach 1:
The patent replaces the mechanical tactile feedback system (physical bumps and ridges on hardware keyboards) with a visual indicator system displayed on the software keyboard. The indicators include horizontal and vertical bands, pointing marks, and circles that provide visual cues for home key positions, substituting the mechanical sensing mechanism with optical display elements that achieve the same functional goal of guiding finger placement.
2Ease of operation
If visual indicators are displayed on the keyboard, then home key recognition is improved, but display complexity increases
Solution Approach 1:
The patent divides the visual indicator system into multiple distinct components: horizontal bands, vertical bands, pointing marks, and circles. Each segment serves a specific directional purpose (horizontal indicators for left-right positioning, vertical indicators for up-down positioning), allowing the complex information to be broken down into manageable visual elements that can be processed independently by the user.
Solution Approach 2:
The patent employs indicators that extend in both horizontal and vertical directions simultaneously. By adding the vertical dimension to the traditional horizontal keyboard layout indicators, the system provides comprehensive spatial guidance for home key positioning, allowing users to locate keys from multiple directional perspectives rather than relying on a single linear indicator.

AI summary
Apparatuses, methods, and program products are disclosed for pointing to at least one key on a software keyboard. By use of a processor, a keyboard is displayed on a display device. At least one indicator that emphasizes at least one key of the keyboard is displayed. The at least one indicator may be at least one of a band, a pointing mark, and circles gradually decreasing in size.
