Fixed User Icon Layout for Error-Resistant Login Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing systems face challenges in facilitating intuitive user selection and reducing login errors due to mistaken user display selection, particularly in image forming apparatuses like multifunction peripherals, where users often select the wrong icon during login.
Innovation Solution
An information processing apparatus and method that fixes user displays at predetermined positions on the screen, uses unique icons associated with user information, and highlights non-registered displays to prevent mistaken selection, simplifying the login process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user displays are arranged freely on the display screen, then the system can accommodate more users and provide flexibility in layout, but users may have difficulty in intuitively selecting the desired user display and may make mistaken selections
Solution Approach 1:
The display screen is segmented into multiple fixed display positions, with each position dedicated to a specific user display. This segmentation allows the system to accommodate multiple users while maintaining a structured layout that enhances user selection intuitiveness.
Solution Approach 2:
Each user display is assigned to a specific fixed position on the display screen, creating local quality differentiation. This means that each position has a specific function (displaying a particular user's information), which helps users intuitively identify and select the desired user display.
2Ease of operation
If user icons are allowed to move freely or be repositioned, then users can customize their preferred positions, but this increases the risk of login errors due to mistaken selection
Solution Approach 1:
The system pre-assigns fixed display positions to user displays before the login process. This preliminary assignment ensures that users cannot accidentally move or swap positions, thereby preventing login errors while still allowing users to select from available fixed positions.
Solution Approach 2:
Instead of allowing users to move icons freely and then trying to prevent errors, the system inverts the approach by fixing the positions first and allowing users to select from these fixed positions. This inversion fundamentally eliminates the possibility of position-related login errors.
3Adaptability or versatility
If the system supports multiple user displays without fixed positions, then it can handle a larger number of users, but the complexity of managing and identifying user displays increases
Solution Approach 1:
The display screen is divided into multiple fixed positions, each capable of holding one user display. This segmentation allows the system to scale to support multiple users while maintaining a simple, structured management approach where each position is independently managed.
Solution Approach 2:
Each fixed display position serves as a universal slot that can accommodate any user display. This multi-functionality allows the system to support a large number of users without increasing complexity, as the same fixed position structure is used regardless of the number of users.

AI summary
An information processing apparatus includes: a display that displays one or more user displays corresponding to one or more users on a display screen; a processor that executes processing for logging in, among the one or more users, as a user corresponding to a user display selected from the one or more user displays; and one or more controllers that perform control for displaying the one or more user displays, each at a predetermined display position fixed on the display screen.
