Solution Overview

Problem

Existing task management interfaces on intelligent terminals require complex operations for enabling functions of opened or running application programs, affecting user experience.

Innovation Solution

A method and apparatus that enable a task management interface by displaying a preview of application programs and their functions, allowing direct switching to the foreground and execution of functions via icons, utilizing entrance parameters stored during application exit or user habits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the traditional multi-step operation method is used to enable a function in an application program, then the system maintains comprehensive control and tracking of user actions, but the operation complexity increases significantly and user experience deteriorates

Engineering Contradiction:
Improveoperation simplicityVSAvoidoperation steps
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by displaying preview interfaces of application functions in advance on the task management interface. The system pre-processes and presents function information (such as frequent destination functions) before the user actually needs to access them, allowing users to directly select from visible previews rather than navigating through multiple menu layers. This resolves the contradiction by reducing operation steps while maintaining system control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the complex application function access path into distinct visual components on the task management interface. Instead of a single hierarchical menu structure, the system divides function access into separate preview cards or interface snippets that display individual functions (e.g., frequent destination, recent locations) as independent selectable elements. This segmentation allows users to access specific functions directly without traversing the entire navigation hierarchy, thereby simplifying operations.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the task management interface displays detailed function information and preview interfaces, then user convenience improves, but the interface complexity and information density increase

Engineering Contradiction:
Improvefunction access convenienceVSAvoidinterface structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts specific function information (such as frequent destination entries, recent location data) from the full application interface and presents them as condensed preview elements on the task management interface. Rather than displaying the complete application menu structure, the system pulls out only the most relevant and frequently used function previews, allowing users to access these functions directly from the task management view without entering the full application. This extraction approach improves convenience while controlling interface complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Speed

If the system stores and retrieves entrance parameters for quick function access, then operation speed increases, but memory usage and data management complexity increase

Engineering Contradiction:
Improvefunction access speedVSAvoidstored data
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The system performs preliminary action by storing entrance parameters (such as function identification data, navigation paths) when applications are first used or when functions are frequently accessed. These parameters are cached in advance so that when users view the task management interface, the system can quickly retrieve and display relevant function previews without real-time computation. This pre-storing approach accelerates function access speed while managing data storage efficiently by only keeping essential parameter information.

Inventive Principle:
Principle #10Preliminary action

AI summary

Embodiments of the present invention relate to a method, an apparatus, and a device for enabling a task management interface, where the method includes: receiving an instruction for enabling the task management interface; in response to the instruction for enabling the task management interface, displaying the task management interface, where the task management interface includes a preview interface of at least one application program and an icon corresponding to at least one function of the application program; receiving an operation instruction for the icon; and in response to the operation instruction, switching the application program corresponding to the icon to a foreground, and executing the function. Therefore, it is convenient for a user to quickly enable a function of an application program included in the task management interface, thereby improving user experience.
