Soft Key Objects on Character Input Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile electronic devices require users to transition from a character input screen to a selection screen to choose an application, which can be cumbersome and inconvenient.
Innovation Solution
A mobile electronic device with a display unit and operating unit that displays a character input screen with soft key objects, allowing users to select and rearrange these objects while maintaining the character input screen, enabling the execution of applications directly from the character input screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users transition to a selection screen to choose an application after character input, then application selection is enabled, but operation complexity increases and user convenience deteriorates
Solution Approach 1:
The patent combines the character input screen and application selection functionality into a single integrated interface. Soft key objects displaying application icons and names are superimposed on the character input screen, allowing users to select applications without transitioning to a separate selection screen. This merging eliminates the need for screen transitions while maintaining both character input and application selection capabilities.
Solution Approach 2:
The character input screen is designed to serve multiple functions simultaneously: it acts as both a character input interface and an application selection interface. The soft key objects on the screen enable application selection, while the main area remains functional for character input, making the screen universal for both purposes.
2Adaptability or versatility
If soft key objects are displayed on the character input screen, then application selection is enabled, but the area for character input may be reduced
Solution Approach 1:
The soft key objects are positioned in specific localized areas of the screen (typically at the bottom or sides) rather than occupying the entire character input area. This allows different parts of the screen to have different functions: the main area remains dedicated to character input while localized regions display application selection options.
Solution Approach 2:
The soft key objects are displayed in a dimensional arrangement that utilizes screen space efficiently, such as arranging application icons in a grid or linear format along the edges or bottom of the screen. This dimensional placement allows application selection without significantly encroaching on the character input area.
3Adaptability or versatility
If multiple soft key objects are displayed in a line, then application variety is increased, but screen space consumption increases
Solution Approach 1:
The application selection interface is segmented into discrete soft key objects, each representing a different application. These segmented objects can be independently arranged and positioned, allowing efficient use of screen space while presenting multiple application options. The segmentation enables flexible layout arrangements that accommodate various application counts.
Solution Approach 2:
The arrangement of soft key objects is dynamic and can be adjusted based on screen space availability, device orientation, and user preferences. The system can automatically rearrange or scroll through soft key objects to accommodate different display conditions while maintaining access to all applications.

AI summary
According to an aspect, a mobile electronic device includes: a display unit, an operating unit, and a control unit. The display unit for displays a character input screen including a part of a plurality of soft key objects each associated with a process in a line. The operating unit receives input of an operation. Upon detecting a changing operation through the operating unit, the control unit changes arrangement of the soft key objects such that at least one of the soft key objects that has been displayed is not displayed and at least one of the soft key objects that has not been displayed is displayed.
