Touch Screen Region Segmentation for Multitasking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smartphones and tablets face inconvenience when multitasking with multiple applications, requiring frequent screen switching and overlapping workspaces, which hinders user experience and efficiency.
Innovation Solution
A touch screen architecture that divides the screen into two independent regions, allowing users to simultaneously display and manage multiple applications by detecting specific gestures to rotate or reorient the second screen while maintaining the first screen's display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single application is displayed on the entire touch screen, then the display is simple and clear, but the user cannot execute multiple applications simultaneously and must frequently switch screens
Solution Approach 1:
The touch screen is divided into two independent regions: a first region displaying a first application and a second region displaying a second application. This segmentation allows simultaneous execution and display of multiple applications without requiring screen switching, directly resolving the contradiction between multitasking capability and operational simplicity.
2Adaptability or versatility
If the user performs multi-tasking of multiple applications, then multiple applications can be accessed, but the user continuously performs manipulation for switching screens and cannot readily recognize application progress
Solution Approach 1:
By segmenting the screen into two independent display regions, the system allows both applications to be visible and accessible simultaneously. The user can switch between applications by simply touching different regions without time-consuming screen transitions, eliminating the time loss associated with frequent screen switching while maintaining application execution flexibility.
3Adaptability or versatility
If a plurality of users use a single smart phone or tablet, then device sharing is enabled, but workspaces of each user overlap and cause inconvenience
Solution Approach 1:
The screen is segmented into distinct regions that can be assigned to different users or applications. This spatial separation prevents workspace overlap by giving each user or application its own dedicated display area, allowing multiple users to share the device simultaneously without interference while maintaining ease of operation for each user.
4Productivity
If the screen is divided into two regions to display multiple applications, then multitasking is improved, but the display architecture becomes more complex
Solution Approach 1:
The screen is divided into two independent regions that can be controlled separately. Each region functions as an independent display area that can show different applications simultaneously. This segmentation approach achieves improved multitasking efficiency while maintaining relatively simple architecture by using standard touch screen technology with regional control logic.
5Productivity
If conventional screen switching is used to execute another application, then application execution is achieved, but the user must perform manipulation to switch to initial menu screen and then execute the other application
Solution Approach 1:
The screen is segmented so that touching the second region directly displays the second application without requiring navigation through the initial menu screen. This eliminates the multi-step manipulation process and enables direct application execution, dramatically improving both application switching speed and operational simplicity.

AI summary
An apparatus for screen change includes a touch screen to divisionally display a first region where a first screen is displayed and a second region where a second screen is displayed, and a controller to detect whether a display change event for a screen display change occurs in at least one of the first region and the second region, and to analyze the display change event and to change a display direction of the second screen while maintaining a display of the first screen.
