Software Keyboard Specific Display Region for Punctuation Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal devices face challenges in efficiently inputting specific characters like punctuation and symbols, as they often require switching to an additional screen, leading to complex and time-consuming operations.
Innovation Solution
A mobile terminal device with a touch input region on the display screen that displays a software keyboard and allows for quick selection of specific keys from a set of input candidate key groups, without necessitating a change in the software keyboard or an excessively wide display/input area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an additional screen is displayed to input specific characters like punctuation and symbols, then the variety of input characters is improved, but the operability and input speed deteriorate due to screen switching
Solution Approach 1:
The patent merges the specific character input function with the main software keyboard screen by providing a specific display region that shows frequently used specific characters (punctuation, symbols) directly on the keyboard interface. Users can access these characters without switching to a separate screen, thus combining multiple input functions into a single unified interface that maintains both versatility and ease of operation.
Solution Approach 2:
The patent prepares frequently used specific characters in advance by displaying them in the specific display region of the software keyboard. This preliminary arrangement allows users to access common punctuation and symbols immediately without needing to switch screens or search through additional character sets, thereby improving input speed and operability while maintaining character variety.
2Area of stationary object
If the software keyboard is displayed on a limited display screen, then the device compactness is improved, but the number of displayable keys deteriorates
Solution Approach 1:
The patent segments the keyboard display into two functional regions: a main software keyboard area for standard keys and a specific display region for frequently used specific characters. This segmentation allows efficient use of the limited display screen area by organizing keys according to usage frequency and importance, enabling more keys to be effectively accessible within the same screen real estate.
Solution Approach 2:
The patent applies local quality by providing enhanced display treatment to the specific display region that shows frequently used specific characters. This region receives special attention in terms of visibility and accessibility, allowing these important characters to be prominently displayed without requiring the entire screen to be enlarged, thus maintaining compactness while increasing the effective number of displayable keys.
3Adaptability or versatility
If the software keyboard display is changed to accommodate specific characters, then the completeness of character set is improved, but the continuity of operation deteriorates
Solution Approach 1:
The patent merges the complete character set accessibility with the continuous software keyboard display by integrating the specific character display region directly into the keyboard interface. This allows users to access punctuation and symbols without leaving the keyboard screen, maintaining operational continuity while providing access to a complete character set including both standard letters and specific characters.

AI summary
A mobile terminal device includes a display section having a display screen, an input section having a touch input region on the display screen, and a control section for displaying a plurality of keys. The display screen is provided as a software keyboard where a touch operation on a specific key causes an input of the specific key. In the specific display region on the display screen that can display operation keys on the software keyboard, the control section selects these keys from a previously prepared set of input candidate key groups. In response to a specific operation on the specific display region, the control section allows the plurality of keys to be displayed on the specific display region. In response to touch on a desired key in the specific display region, the control section determines that an input of the key has been performed.
