Dynamic Software Keyboard Key Grouping for Small Display Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In small display areas, traditional software keyboards can be difficult to use due to the non-display of low-use-frequency keys, which reduces user operability.
Innovation Solution
An information processing apparatus that displays a first key image group and a second key image group in different modes, with the second group displayed larger when a display switching key is activated, allowing for the non-display of less frequently used keys and enhancing user operability by enlarging essential key images.

Engineering Contradiction Analysis
1Area of stationary object
If low-use-frequency keys are not displayed to save space, then area efficiency is improved, but user operability deteriorates
Solution Approach 1:
The keyboard display dynamically adjusts its configuration based on user needs. The system switches between a first keyboard image (showing all keys including low-use-frequency keys) and a second keyboard image (showing only high-use-frequency keys in enlarged size). This dynamic switching resolves the contradiction by allowing the display to be compact when needed while maintaining full functionality when required.
Solution Approach 2:
The keyboard is segmented into different key groups: high-use-frequency keys and low-use-frequency keys. The segmentation allows the display to show only essential keys in the limited display area, while providing access to other keys through switching mechanisms. This resolves the contradiction by separating frequently accessed functions from less critical ones.
2Ease of operation
If all keys are displayed on a small screen, then user operability is improved, but display area efficiency deteriorates
Solution Approach 1:
The system dynamically switches between displaying all keys and displaying only essential keys in enlarged format. When the first keyboard image is shown, all keys are visible but smaller. When the second keyboard image is shown, high-use-frequency keys are enlarged for better operability while low-use-frequency keys are hidden. This dynamic adaptation resolves the area efficiency problem.
Solution Approach 2:
Low-use-frequency keys are extracted from the main display area and made available through a separate switching mechanism. This allows the main display to focus on essential keys with larger size, improving operability for common operations while keeping the display area efficient. The extracted keys remain accessible when needed.

AI summary
An information processing apparatus includes: a reception module configured to receive an operation input by a user; and a display module configured to display key images for receiving the operation, wherein the display module is configured to operate to: display a first key image group comprising one or more key images, a second key image group comprising one or more key images in a first display mode, and a first display switching key image; and display the second key image group in a second display mode which is larger in size than the second key image group in the first display mode, without displaying the first key image group, when the operation on the first display switching key image is received by the reception module.
