Software Keyboard Password Strength Display for Limited Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with limited display regions, such as image forming apparatuses and mobile terminals, face challenges in displaying a password strength meter while inputting a password using a software keyboard, as the keyboard covers the screen, leaving no space for the meter.
Innovation Solution
An information processing apparatus that displays a password strength meter alongside the software keyboard during password input, allowing the meter to be toggled on or off based on user settings, ensuring it does not obstruct the input process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a software keyboard is displayed for password input on a device with limited display region, then password input functionality is provided, but no space remains for displaying a password strength meter
Solution Approach 1:
The patent combines the password strength meter display with the software keyboard interface by integrating it into the header region of the keyboard. This merging allows both the password input functionality and the strength meter to coexist within the same display area, resolving the space conflict between these two elements.
Solution Approach 2:
The header region of the software keyboard is designed to serve multiple functions: it displays both the password strength meter and provides interface elements for password input operations. This multi-functionality allows the limited display space to accommodate both information display and interaction requirements.
2Loss of information
If a password strength meter is displayed alongside the software keyboard, then password strength information becomes visible, but the display region is exceeded on devices with limited screen space
Solution Approach 1:
The patent places the password strength meter in a specific local region (the header of the software keyboard) rather than attempting to display it independently. This localized placement ensures that the strength information is presented in a dedicated space that does not interfere with the main keyboard input area, allowing both elements to fit within the limited display region.
3Ease of operation
If the password strength meter is integrated into the software keyboard interface, then both password input and strength display are achieved simultaneously, but the interface complexity increases
Solution Approach 1:
The software keyboard interface is segmented into distinct functional regions: the header region for displaying password strength information and the main keyboard area for input operations. This segmentation allows the interface to maintain clarity and usability while integrating multiple functions, as each region has a specific purpose and does not interfere with the other.

AI summary
An information processing apparatus includes a user interface. The apparatus displays a software keyboard for inputting a password, using the user interface; in a case where a password strength meter indicating a strength of a password is set to be displayed using the user interface, calculates a strength of a password input from the software keyboard; and displays the software keyboard and the password strength meter indicating the strength of the input password, and in a case where a password strength meter indicating a strength of a password is set not to be displayed using the user interface, displays the software keyboard. In the case where a password strength meter indicating a strength of a password is set not to be displayed using the user interface, the password strength meter is not displayed.
