Login Device Icon Positioning for Usability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing login devices face usability issues due to the need for users to constantly search for their icons, which are rearranged based on priority, leading to decreased user experience during the login process.
Innovation Solution
A login device with a controller, storage, and display system that allows users to select a specific display for login, providing an identifiable display for users based on their information and changing the display manner according to their operational state, ensuring the icon's position remains fixed, enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If icons are rearranged according to priority, then job processing efficiency is improved, but user search time increases and usability deteriorates
Solution Approach 1:
The display area is segmented into a fixed position region and a variable region. User icons are divided into two categories: frequently used icons are fixed in the fixed position region, while other icons are arranged in the variable region according to priority. This segmentation allows simultaneous optimization of both accessibility and job processing efficiency.
Solution Approach 2:
User icons are pre-arranged in optimal positions based on usage frequency and job priority before the user needs to access them. The system performs preliminary sorting and positioning of icons, so that when users need to access their icons, they are already in the most accessible locations, eliminating the need for real-time searching.
2Productivity
If icon positions are uniformly changed, then job priority management is improved, but user experience deteriorates due to increased search time
Solution Approach 1:
Different regions of the display have different qualities: the fixed position region provides stable, predictable locations for frequent users, while the variable region allows dynamic reorganization based on job priorities. This local differentiation enables priority management without requiring uniform changes across the entire display.
Solution Approach 2:
Instead of moving all icons uniformly when priorities change, the system inverts the approach by keeping frequently accessed icons fixed and only reorganizing less frequently accessed icons. This inversion minimizes disruption to user experience while still enabling priority-based management.
3Device complexity
If login screen is in initial state, then system simplicity is maintained, but usability decreases as users must search for their icons
Solution Approach 1:
The login screen serves multiple functions simultaneously: it maintains a simple initial state for system clarity while incorporating intelligent icon positioning that provides quick access for users. The fixed position region acts as a universal access point that works for all users regardless of their specific needs, combining simplicity with enhanced usability.

AI summary
To provide a login device including a controller, a storage that stores a user capable of a login, where the user includes a plurality of the users, a display device that displays specific displays corresponding to the users, in a display screen, and a processing device that executes a login process with a user corresponding to a specific display selected from the displayed specific displays. If job data including user information is acquired, the controller provides an identifiable display on a specific display for a user corresponding to the user information.
