Login Screen Display Method for Computer System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems require user identification each time a user logs in, leading to inappropriate login screens being displayed, especially when multiple login methods are provided.
Innovation Solution
A computer system and login screen display method that store the user's login method upon initial login, allowing subsequent logins to display the appropriate login screen without requiring user identification information, such as an email address, by utilizing a portal screen with application icons and supporting various login methods like email and password, tenant ID, external services, or all methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user identification is performed each time a user logs in, then the appropriate login screen can be displayed, but the login process becomes inefficient and requires repeated user identification
Solution Approach 1:
The system performs user identification in advance during the initial login process and stores the identified user information. This preliminary action eliminates the need for repeated user identification in subsequent login sessions, thereby improving login efficiency while maintaining system security.
Solution Approach 2:
The system creates a copy of the user identification information after initial authentication and stores it for future use. This copying mechanism allows the system to retrieve stored user information instead of performing complete re-identification, reducing the complexity of the login process while maintaining appropriate access control.
2Ease of operation
If multiple login methods are provided, then user convenience is improved, but determining the appropriate login screen becomes difficult without user identification
Solution Approach 1:
The system determines and stores the user's preferred login method during the initial login process. This preliminary determination of the login method allows the system to automatically select and display the appropriate login screen in subsequent sessions, improving ease of operation while avoiding the complexity of manual login method selection.
Solution Approach 2:
The system automatically selects and displays the appropriate login screen based on stored user preferences without requiring users to manually specify their login method each time. This self-service approach improves convenience by eliminating repetitive user actions while managing the complexity of multiple login methods internally.

AI summary
A computer system (1) includes an information processing system (50) configured to authenticate a user using one of multiple login methods and a terminal (20) configured to request the information processing system (1) to authenticate the user. The terminal (20) includes a process controller (25) configured to determine a login method based on a previously-used login method and a display controller (23) configured to display a login screen corresponding to the login method determined by the process controller (25).
