Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with single touch screens face limitations in screen size and input device usage, making it difficult to divide screens and utilize applications effectively compared to desktop computers.
Innovation Solution
An apparatus and method utilizing multiple touch screens that change screens through continuous multiple touches, providing visual, auditory, or tactile feedback, allowing for screen changes via touch gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device uses a single touch screen, then the device structure remains simple, but the screen size is limited and screen division capability is poor
Solution Approach 1:
The patent divides the single touch screen into multiple virtual display regions that can be independently controlled and manipulated. Users can create multiple virtual screens on one physical display, enabling screen division and multi-tasking without adding multiple physical screens, thus improving versatility while maintaining simple device structure.
2Area of stationary object
If a mobile device uses a single touch screen, then the device remains compact, but the effective working area is limited
Solution Approach 1:
The patent extends the effective working area by utilizing the temporal dimension through virtual screen switching and overlay. Multiple virtual displays can be stacked or arranged in sequences, allowing users to access more content and applications without physically expanding the screen area, thus increasing effective working area while keeping the device compact.
3Ease of operation
If multiple touch screens are added to a mobile device, then screen division and application usage improve, but the device complexity increases
Solution Approach 1:
The patent creates virtual copies of display functionality within the single touch screen. Instead of adding multiple physical screens, the system generates multiple virtual display instances that can be independently configured and manipulated, providing enhanced application usage and screen division capabilities while avoiding the complexity of multiple physical display hardware.
4Adaptability or versatility
If virtual screens are created on a single touch screen, then screen division capability improves, but the detection and control of multiple touches becomes more difficult
Solution Approach 1:
The patent introduces a virtual display management system that acts as an intermediary layer between the physical touch screen and the user interface. This intermediary software layer manages touch input routing, virtual screen creation, and coordinate mapping, simplifying the detection and control of multiple touches by abstracting the complexity from the hardware level to the software level.

AI summary
An apparatus and method of changing screens using multiple touch screens. The method includes displaying a first screen in a first touch screen; displaying a second screen in a second touch screen; detecting multiple touches in the first touch screen; detecting continuous movements of the multiple touches from the first touch screen to the second touch screen; and changing the second screen of the second touch screen in response to the continuous movements of the multiple touches..
