Screen Control Section for User-Matched Post-Resume Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processors face challenges in generating a suitable post-system-resume screen, particularly when multiple users are logged in, as restoring the exact previous state can be inflexible and uncomfortable for users, especially if different users log in after suspension.
Innovation Solution
Incorporating a mode control section and screen control section that select power saving mode and generate display screens matching the user who logs in after switching from power saving mode to normal mode, ensuring a seamless user experience by adapting the screen content based on the logged-in user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system restores to the status immediately before suspend, then the user can continue from the previous state, but the user experience becomes uncomfortable when a different user logs in after suspend
Solution Approach 1:
The system dynamically determines the post-suspend screen based on the logged-in user. When the same user logs in, the system restores to the previous screen status. When a different user logs in, the system switches to that user's previous screen status. This dynamic adaptation resolves the contradiction by making the restoration behavior flexible rather than fixed.
Solution Approach 2:
The system applies different restoration behaviors to different users based on their individual login status. Each user has their own screen status history stored separately, allowing the system to provide personalized restoration experience for each user while maintaining reliable state restoration overall.
2Manufacturing precision
If the system requires all users to log in to restore previous screen, then screen restoration accuracy is improved, but system flexibility deteriorates
Solution Approach 1:
The system extracts and stores screen status information separately for each user in the storage section. This allows the system to restore screens accurately for individual users without requiring all users to log in simultaneously. The extracted user-specific screen data enables precise restoration while maintaining system flexibility.
Solution Approach 2:
The system performs preliminary storage of screen status information for each user before suspend occurs. This preliminary action captures the screen state associated with each logged-in user, enabling accurate restoration when any of those users logs in later, without requiring simultaneous login of all users.
3Adaptability or versatility
If the system stores screen status for multiple users, then user-specific screen restoration is enabled, but device complexity increases
Solution Approach 1:
The storage section serves multiple functions: it stores both user login information and screen status information, and manages data for multiple users simultaneously. The screen control section universally handles screen generation for any logged-in user by querying the storage section for that user's screen status, reducing overall system complexity through multi-functionality.
Solution Approach 2:
The system merges the storage of user login information and screen status information into a single storage section. This combination reduces device complexity by consolidating data storage functions while still enabling user-specific screen restoration through integrated data management.

AI summary
The present disclosure provides a technology for suitably generating a post-system-resume screen. An information processor includes: a mode control section adapted to select power saving mode as an operation mode; and a screen control section adapted to generate a display screen, in which when a user logs in after the mode control section switches the mode from power saving mode to normal mode, the screen control section generates a display screen to match the user who has logged in.
