Gesture Based Edit Mode for Touch Screen Document Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch screen systems with multiple touch points and gesture recognition face challenges in simplifying complex editing functions like cut, copy, paste, undo, and selection, as users find it difficult to remember extensive sets of gestures for these operations.
Innovation Solution
A gesture-based edit mode system that uses a touch or gesture input device to detect user inputs and convert them into electrical signals, processed by a processor to recognize specific gestures for editing operations such as cut, paste, copy, undo, and selection, allowing for a simplified and consistent method of performing document editing across various applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an extensive set of gestures is provided to extend and simplify touch screen operations, then the functionality and versatility of the touch screen system is improved, but the difficulty for users to remember and operate the system increases
Solution Approach 1:
The patent segments the extensive gesture set into two categories: common gestures that are simplified and easy to remember, and advanced gestures that provide extended functionality. This segmentation allows the system to offer comprehensive features while maintaining ease of use for frequent operations.
Solution Approach 2:
The patent introduces an intermediary mechanism (such as a gesture menu or context-sensitive options) that mediates between simple gestures and complex functions. When a user performs a basic gesture, the intermediary presents additional options or interpretations, effectively bridging the gap between simple operation and advanced functionality.
2Adaptability or versatility
If multiple touch points and gesture recognition are implemented to enhance user interaction, then the adaptability of the system is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal gesture recognition framework that handles multiple touch points and gesture types through a single, unified system. This multi-functional approach allows the same hardware and software infrastructure to support a wide variety of interaction modes without proportionally increasing complexity.
Solution Approach 2:
The patent utilizes parameter changes in gesture recognition, such as varying the number of touch points, duration, pressure, or movement patterns, to differentiate between gesture types. By encoding multiple functions through variations of basic parameters rather than requiring entirely separate recognition systems, the patent enhances adaptability while controlling complexity.

AI summary
A system and method for document editing. A system includes an operator input device, a processor, gesture recognition program, and an edit mode program. The operator input device that senses gestures and multiple simultaneous touch points. The processor is coupled to the operator input device. The processor executes the gesture recognition program, which recognizes inputs from the input device. The gesture recognition program recognizes a predetermined edit mode gesture and, based only on the gesture, causes the processor to execute the edit mode program. The edit mode program provides a plurality of document editing functions for modifying a currently displayed document.
