Dual Touch Panel Clipboard Interface for Intuitive Copy Paste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in intuitively determining if an item has been successfully copied to the clipboard and selecting items to paste from the clipboard in information processing apparatuses, such as smartphones and tablets, due to the lack of intuitive operation methods.
Innovation Solution
The apparatus employs a dual-touch interface with a front and rear touch panel, allowing users to copy items from a front window to a rear window (clipboard) and paste them back, using position information from both panels to enable intuitive copy and paste operations through overlapping windows and touch operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the clipboard (sub screen) is displayed on the display by operating the rear touch panel so that the basic screen and the sub screen are simultaneously displayed on the display, then the user can visually confirm the clipboard content and perform copy-paste operations, but the size of each screen is reduced
Solution Approach 1:
The patent introduces a third dimension by placing the touch panel on the back surface of the device, opposite to the display screen. This allows the clipboard to be displayed and operated on a separate surface (rear touch panel) while the main content remains on the front display, effectively using spatial separation to resolve the screen size reduction issue. The rear touch panel coordinates are mapped to the front display coordinates, enabling intuitive copy-paste operations without compromising the visibility or size of either interface.
2Area of moving object
If the sub screen is displayed half translucently to overlap with the basic screen, then display area is secured, but simultaneous operation of the basic screen and the sub screen is not allowed
Solution Approach 1:
The patent divides the user interface into two separate, independent interaction surfaces: the front display screen for the basic application and the rear touch panel for clipboard operations. This segmentation allows both screens to be operated simultaneously without interference, as each surface handles distinct functions. The rear touch panel specifically manages clipboard copy-paste operations, while the front display maintains full functionality for the primary application.
3Ease of operation
If a touch panel is provided on the back side of the display, then intuitive copy and paste operations are enabled through spatial separation, but the device structure becomes more complex
Solution Approach 1:
The rear touch panel serves multiple functions: it acts as the clipboard interface for copy-paste operations, provides spatial separation for intuitive interactions, and maintains coordinate mapping with the front display. This multi-functionality justifies the additional structural complexity, as the same component serves several critical roles in enabling the patent's core functionality.

AI summary
An information processing apparatus comprises a display, comprising: a display control unit configured to display a first window and a second window on the display with the second window positioned behind the first window and at least partially overlapped with the first window; a first obtaining unit configured to obtain a first position information representing a position within a display range of the display designated on the display. The information processing apparatus further comprises a second obtaining unit configured to obtain a second position information corresponding to position information representing a position within the display range of the display, the second position information designated in an area corresponding to a rear side of the display and existing on one surface among the surfaces constituting the information processing apparatus.
