Portable Terminal Multi-Tasking Interface with Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals with single-tasking environments struggle to provide intuitive multi-tasking capabilities, making it difficult for users to manage and switch between applications running in the background, as existing methods require cumbersome key inputs and lack clear visualization of running applications.
Innovation Solution
A multi-tasking execution apparatus and method that displays specific images representing background applications on a portable terminal's screen, allowing users to control these applications through intuitive gestures, such as dragging and tapping, to pause, quit, or resume them, with visual effects indicating the actions taken.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-tasking software platform is used in portable terminals, then the device complexity is reduced and ease of operation is maintained, but the adaptability to multi-tasking environments and user convenience deteriorates
Solution Approach 1:
The interface is segmented into multiple functional areas: a first area displaying information about the application currently running in the foreground, and a second area displaying a list of applications running in the background. This segmentation allows the system to maintain simple operation for single-tasking while adding multi-tasking capabilities through the additional display area.
Solution Approach 2:
The patent adds a spatial dimension to task management by displaying background applications in a separate area rather than requiring users to switch between full-screen applications. This dimensional approach allows foreground and background tasks to coexist visually, improving adaptability without complicating the basic operation model.
2Loss of information
If background applications are hidden when paused, then the interface simplicity is maintained, but the user's ability to determine application state and control background applications deteriorates
Solution Approach 1:
The system provides visual feedback by displaying background applications in the second area with indicators showing their running state. This feedback mechanism allows users to immediately see which applications are running in the background without needing to switch between them or use complex commands, resolving the contradiction between information visibility and operational simplicity.
3Loss of time
If a traditional method requiring key inputs is used to check running applications, then the device complexity is reduced, but the user convenience and time efficiency deteriorate
Solution Approach 1:
The system performs preliminary action by continuously maintaining a display of background applications in the second area, so information is already prepared and visible when the user needs it. This eliminates the need for users to initiate key input sequences to check running applications, reducing time loss without significantly increasing interface complexity since the display is continuously available.
4Loss of information
If recently used programs are displayed together with background applications, then the interface simplicity is maintained, but the user's ability to identify currently running background applications deteriorates
Solution Approach 1:
The patent applies local quality by providing different visual characteristics or information presentation for different types of applications in the second area. Background applications are displayed with specific indicators that distinguish them from recently used programs, allowing users to quickly identify which applications are currently running in the background versus which were merely used previously. This localized differentiation maintains overall interface simplicity while solving the identification problem.
Data Source
AI summary
A multi-tasking execution apparatus and a method for easily controlling applications running in a portable terminal are provided. The apparatus includes a display and a controller. The display displays an application-containing image in which at least one specific image representing at least one application running in a background is contained and arranged. The controller operatively displays at least one specific image representing at least one application running in the background, so as to be contained in the application-containing image, and controls the at least one application running in the background by controlling the specific image based on a specific gesture.
