Touchscreen Split-Screen Gesture for Faster Multitasking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with split screen functions require cumbersome and prone-to-misoperation multi-step processes for activation, such as sidebar or dock activation and multi-task interface triggers.
Innovation Solution
A split screen method utilizing a two-finger sliding operation on a touch screen to determine a sliding direction, splitting the displayable area into first and second split screen areas, with one area displaying a multi-task interface, simplifying the operation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-step processes (sidebar activation, dock activation, multi-task interface triggers) are used for split screen activation, then the split screen function can be activated, but the operation process becomes cumbersome and prone to misoperation
Solution Approach 1:
The patent segments the complex multi-step activation process into a single atomic gesture operation. By dividing the touch screen into different regions and assigning specific meanings to sliding directions, the system transforms a cumbersome multi-step process into a simple, reliable single-step operation that is less prone to misoperation.
Solution Approach 2:
The patent introduces a gesture recognition mechanism as an intermediary between user input and split screen activation. This intermediary layer interprets the two-finger sliding gesture and translates it into the appropriate split screen configuration, eliminating the need for multiple intermediate steps like sidebar activation or dock manipulation.
2Adaptability or versatility
If multiple activation steps are required, then various split screen configurations can be achieved, but the number of operation steps increases
Solution Approach 1:
The patent adds dimensional information to the gesture input by considering both the starting position (dividing the screen into regions) and the sliding direction. This dimensional enrichment allows a single gesture to encode multiple pieces of information that would otherwise require multiple steps, enabling versatile split screen configurations while reducing activation time.
Solution Approach 2:
The patent changes the parameter space of the input operation from simple button presses or taps to a continuous gesture with position and direction parameters. By utilizing the continuous nature of touch gestures, the system can map different gesture parameters to different split screen configurations, achieving versatility without increasing the number of discrete steps.
Data Source
AI summary
A split screen method, an electronic device, and a storage medium are disclosed. The method includes: in response to a two-finger sliding operation acting on a touch screen, obtaining a sliding direction corresponding to the two-finger sliding operation; and splitting a displayable area into a first split screen area and a second split screen area based on the sliding direction, one of the first split screen area and the second split screen area is used to display a multi-task interface. In this way, split screen operation steps are simplified to improve a split screen speed.
