Touch Panel Document Division Using Finger Traced Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document editing technologies on touch panels require the use of pointing devices like mice or mechanical switches, limiting the ability to divide or merge documents without such hardware, and do not efficiently utilize touch panel capabilities for intuitive editing.
Innovation Solution
A method and system that allow users to divide or merge documents on a touch panel by identifying and tracing two points on the screen, using a line segment as a dividing or merging line, without the need for external pointing devices, utilizing a contact detecting unit and object display unit connected to an information processing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pointing devices like mice or mechanical switches are used for document editing on touch panels, then editing operations can be performed, but the usability is limited and external hardware is required
Solution Approach 1:
The patent replaces mechanical pointing devices (mice, switches) with direct touch panel gestures. Users interact by tracing lines with their fingers directly on the touch panel surface, eliminating the need for external mechanical hardware and improving ease of operation through intuitive direct manipulation.
Solution Approach 2:
The touch panel itself serves as both the display and the input device. The panel detects finger traces directly on its surface and uses this information to perform document division and merging operations, making the system self-sufficient without requiring external pointing devices.
2Adaptability or versatility
If traditional pointing devices are used for document division and merging, then editing functions are available, but the editing process becomes complex and requires additional tools
Solution Approach 1:
The touch panel is designed to perform multiple functions: it serves as both the display interface and the input control device. The same panel that shows the document also detects user gestures to perform division and merging operations, consolidating multiple functions into a single universal interface.
Solution Approach 2:
The patent combines the display function and input control function into a single integrated system. The touch panel merges visual output and touch input capabilities, allowing document editing operations to be performed using the panel's own surface without separate control devices.

AI summary
Embodiments of the present invention relate to dividing and merging documents on a touch panel. A method includes dividing a document displayed on a touch panel having a display function using an information processing device connected to the touch panel. Positions of two different points on the touch panel are identified in response to a user indicating the two different points in the document. The document is divided, by a computer processor, based on a line segment extending from a starting point to an end point of a traced line traced by the user. The line segment is used as a dividing line in response to the user tracing the traced line on the touch panel so as to traverse the two different points.
