Multi-Screen Terminal Slide Control for Page Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional terminal devices with multiple screens require cumbersome scrolling operations across each screen, leading to discontinuity in page continuity when switching between screens.
Innovation Solution
A terminal device equipped with slide operation detection, judgment, and display control means that detects slide operations on multiple screens and performs intuitive display control based on the presence of adjacent screens in the sliding direction, allowing for seamless page turning across screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a touch screen is used to eliminate controllers for scrolling, then the screen area increases and operation becomes more intuitive, but a scrolling operation is required for each screen individually which is bothersome and disrupts page continuity
Solution Approach 1:
The patent merges the scrolling control of multiple screens into a single unified operation. When a slide operation is detected on one screen, the system identifies adjacent screens in the sliding direction and performs coordinated scrolling across all identified screens simultaneously. This combines what would otherwise be separate scrolling operations into one action, resolving the contradiction between maintaining large screen area and ensuring ease of operation.
Solution Approach 2:
The slide operation on a touch screen serves multiple functions: it scrolls the content on the operated screen and simultaneously scrolls content on adjacent screens in the sliding direction. This multi-functionality allows a single operation to manage multiple screens, eliminating the need for separate scrolling operations on each screen while maintaining the intuitive touch interface.
2Adaptability or versatility
If each screen is scrolled independently, then each screen can be controlled individually, but page continuity is not maintained among screens when information spans multiple pages
Solution Approach 1:
The system employs feedback by detecting the slide operation on one screen, identifying adjacent screens in the sliding direction, and then performing coordinated scrolling on all identified screens. This feedback mechanism ensures that when information spans multiple pages across multiple screens, the page continuity is maintained by scrolling all relevant screens in unison, while still allowing individual screen control flexibility.
3Reliability
If multiple controllers are added to enable scrolling across multiple screens, then page continuity can be maintained, but the device complexity increases and screen area is reduced
Solution Approach 1:
The touch screen's slide operation is designed to serve multiple screens simultaneously, making the single touch interface universal for controlling content across multiple screens. This eliminates the need for separate controllers on each screen, maintaining page continuity through coordinated scrolling while avoiding the complexity and space requirements of multiple independent controllers.
Solution Approach 2:
The patent merges the control functions of multiple screens into a single touch interface. By detecting slide operations on one screen and automatically coordinating scrolling across adjacent screens, the system combines what would require multiple separate controllers into one unified control mechanism, reducing device complexity while maintaining reliability of page continuity.

AI summary
In a terminal device (10), when a slide operation performed on at least either of a plurality of touch screens (TD1, TD2) is detected, a control section (1) performs display control based on a judgment result indicating whether or not another screen is present in the sliding direction. For example, when another screen is not present in the sliding direction, the control section (1) instructs the screens (TD1, TD2) to perform page turning by an amount equivalent to a single screen, or when another screen is present, the control section 1 instructs the screens (TD1, TD2) to perform page turning by a number of pages calculated by the number of screens present in the sliding direction being added to the number of the operation screen.
