Mobile Terminal Recent App List with Multi-Screen Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Recent Application Management Systems in mobile terminals only capture the last used screen of applications, limiting user visibility and navigation to previous screens, making it inconvenient to track activities across multiple screens and leading to potential task abandonment.
Innovation Solution
Capturing multiple images of different screens based on usage patterns and generating a list of recently used applications that includes multiple screens, with real-time monitoring and flagging for updates, allowing users to view recent activities and navigate to specific screens easily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only the last used screen image is captured and stored in the recently used applications list, then the device complexity and memory usage are reduced, but the user cannot view or navigate to previous screens other than the last screen, limiting functionality and user convenience
Solution Approach 1:
The patent segments the single screen image into multiple screen images by capturing images of different screens (e.g., first screen, second screen, third screen) at different time points. This segmentation allows the system to store and display multiple screen snapshots, enabling users to view and navigate to specific previous screens without increasing overall system complexity.
Solution Approach 2:
The patent adds a temporal dimension to screen capture by capturing multiple screens at different time points and associating each screen image with its corresponding time point. This transforms the single-dimension (last screen only) approach into a multi-dimensional system where users can access screens based on both screen identity and time sequence.
2Adaptability or versatility
If multiple images of different screens are captured and stored in the recently used applications list, then user visibility and navigation to previous screens are improved, but the device complexity and memory usage increase
Solution Approach 1:
The patent divides the multiple screen images into segments, each associated with a specific time point and screen identifier. This segmentation allows the system to manage multiple images efficiently by organizing them in a structured manner, reducing the complexity burden of storing multiple images.
Solution Approach 2:
The system performs preliminary actions by capturing and storing screen images at predetermined time intervals or when specific conditions are met (e.g., when transitioning between screens). This preliminary capture and organization of images reduces the complexity of real-time image management and provides ready-to-display screenshots when users access the recent applications list.
3Loss of information
If multiple images of different screens are captured and stored, then users can review recent activities across multiple screens, but the use of energy and memory resources increases
Solution Approach 1:
The patent implements periodic action by capturing screen images at specific intervals or under specific conditions (e.g., when a screen is displayed for a predetermined time, when transitioning between screens, or at scheduled time points). This periodic capture approach reduces energy consumption compared to continuous capture while still providing sufficient screen images for user review.
Solution Approach 2:
The system applies partial action by capturing only the necessary number of screen images based on user needs and system resources. Instead of capturing all possible screens continuously, the system captures a selective subset of screens that are most relevant to user activities, reducing energy and memory usage while maintaining effective functionality.

AI summary
A mobile terminal managing one or more recently used applications and method for same, is disclosed. In the present invention, a plurality of first images corresponding to different screens of a first application being active on a display of the mobile terminal are captured when a transition activity is performed on the first application. Further, a plurality of second images being generated based on the captured plurality of first images. The generated second images are used to generate a list comprising the second images of the first application along with other pre-stored images of other recently used applications different than the first application. The generated list is displayed as the list of one or more recently used applications. Further, one or more of the second images and one or more of the pre-stored images may be flagged in real-time in an event or more notifications have been received for the first application and other recently used applications.
