Solution Overview
Problem
Existing methods for managing concurrently open applications on portable electronic devices with touch-sensitive surfaces are cumbersome and inefficient, leading to cognitive burden and energy wastage, particularly in battery-operated devices.
Innovation Solution
Implementing methods and interfaces that allow for faster and more efficient selection and management of open applications on touch-sensitive displays, including displaying application views without concurrently showing others, using gestures to navigate and select applications, and optimizing energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple application views are displayed concurrently on small screens, then application visibility is improved, but cognitive burden increases and energy consumption increases
Solution Approach 1:
The patent implements dynamic display behavior where the system automatically adjusts between single-view and multi-view display modes based on real-time detection of user interactions. When a user interacts with an application icon or thumbnail, the system transitions to display multiple application views; when no interaction occurs, it returns to displaying a single view. This dynamic adaptation resolves the contradiction by providing enhanced visibility only when needed, thereby reducing unnecessary energy consumption while maintaining application accessibility.
2Loss of information
If multiple application views are displayed concurrently on small screens, then application visibility is improved, but cognitive burden increases
Solution Approach 1:
The system dynamically adjusts the number of displayed application views based on user interaction states. When users are actively selecting or managing applications, multiple views are shown to improve visibility and reduce cognitive burden. When users are not interacting with the application manager, the system displays only a single view to minimize cognitive load. This dynamic behavior ensures that enhanced visibility is provided only when it serves a functional purpose.
3Ease of operation
If existing methods for managing applications are used, then application management capability is maintained, but operation time increases and energy is wasted
Solution Approach 1:
The patent implements preliminary action by automatically displaying thumbnails and previews of concurrently running applications before the user explicitly requests them. When a user interacts with the application manager, the system has already prepared and displayed relevant application information, enabling faster selection and management. This preliminary preparation reduces the time required for application management operations while maintaining full functionality.
4Adaptability or versatility
If touch-sensitive surfaces are used for application management, then interface versatility is improved, but interaction complexity increases
Solution Approach 1:
The system dynamically adapts its interaction complexity based on user behavior. The touch-sensitive interface provides advanced gestures and multi-view displays when users engage with application management functions, but reverts to simpler, more intuitive interactions when users are not actively managing applications. This dynamic simplification reduces the perceived complexity while maintaining the versatility of the touch interface.

AI summary
An electronic device displays a first application on the touch-sensitive display, the first application being one of a plurality of concurrently open applications on the electronic device. The device detects a first input and in response, displays a multitasking user interface that is configured to select an open application for viewing and is also configured to select one of a plurality of contactable users to communicate with. The multitasking user interface includes a set of open application affordances, wherein activation of a respective open application affordance selects a corresponding open application in the plurality of concurrently open applications for viewing, and a first set of contactable-user affordances, wherein activation of a respective contactable-user affordance initiates a process for communicating with a corresponding contactable-user.
