Multi-touch Screen Navigation via Continuous Drag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices with touch screens face limitations in screen size and input operations, making it difficult to navigate long web pages due to smaller screen sizes and the need for multiple touch gestures.
Innovation Solution
A method and device configuration that allows continuous touch movement between two touch screens to seamlessly transition between screens of an application, providing visual, audible, or tactile feedback, and displaying different screens on each touch screen based on the movement, enhancing navigation without the need for multiple gestures.

If a mobile device uses a single touch screen with smaller screen size, then the device is more portable, but the screen is difficult to divide and requires multiple touch gestures for navigation
Solution Approach 1:
The device is divided into multiple touch screens (first touch screen and second touch screen) that can be independently operated. Each touch screen can display different content or portions of the same content, allowing the user to navigate through long web pages or applications by dragging content between screens rather than using multiple gestures on a single screen.
2Ease of operation
If multiple touch gestures are used for navigation on a single touch screen, then the screen size remains small, but the input operations become more complex
Solution Approach 1:
The second touch screen acts as an intermediary for navigation operations. Instead of performing multiple gestures on the first touch screen to navigate through content, the user can simply drag content from the first touch screen to the second touch screen, which automatically scrolls or navigates to the corresponding content position, reducing gesture complexity.
3Ease of operation
If the screen is divided into multiple sections for better navigation, then navigation becomes easier, but the screen size of each section becomes smaller
Solution Approach 1:
The navigation capability is extended from a two-dimensional single screen to a three-dimensional multi-screen space. By adding the second touch screen in the spatial dimension, the system provides larger overall display area while maintaining easy navigation through the drag-and-drop interaction between screens, effectively resolving the trade-off between screen area and navigation capability.

AI summary
A screen change method and device are provided. A first screen, from among a plurality of screens, is displayed on a first touch screen. A second screen, which precedes or succeeds the first screen in a sequence of the plurality of screens, is displayed on a second touch screen. A touch is detected on the first touch screen. Continuous movement of the detected touch from the first touch screen to the second touch screen is detected. Other screens, which are different from the first screen and the second screen, from among the plurality of screens, are displayed on the first touch screen and the second touch screen, in response to the detected continuous movement of the touch.
