Touchscreen Gesture Editing Interface for Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interfaces on portable multifunction devices are complex and inflexible, making it difficult for users to easily edit content such as text and graphics, with editing functions often buried in menu hierarchies and requiring memorization of key sequences.
Innovation Solution
A touch-sensitive display with a graphical user interface that detects multitouch edit initiation gestures to display user-selectable edit option icons and start/end point objects, allowing users to interactively select and manipulate content through gestures on the touch screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional user interfaces with physical pushbuttons and menu hierarchies are used, then device functionality can be accessed, but the interface becomes complex and requires memorization of key sequences
Solution Approach 1:
The patent replaces physical pushbuttons and mechanical menu navigation with a touch-sensitive display that responds to finger gestures. This substitution eliminates the need for physical buttons while providing access to the same device functions through intuitive touch interactions, thereby reducing interface complexity while maintaining functionality.
Solution Approach 2:
The touch-sensitive display allows users to directly interact with the interface by touching and gesturing on the screen itself, rather than requiring separate physical controls. The display surface becomes both the information presentation medium and the control interface, enabling users to navigate and edit content directly where the content is displayed.
2Adaptability or versatility
If pushbutton density is increased to provide more functions, then more features become accessible, but the interface becomes more complex and difficult to operate
Solution Approach 1:
The touch-sensitive display serves multiple functions: it displays information, accepts input through gestures, and provides visual feedback all through a single interface element. This multi-functionality eliminates the need for separate pushbuttons for each function, allowing comprehensive feature access without increasing physical complexity or operational difficulty.
Solution Approach 2:
The patent adds the dimension of gesture-based interaction to the traditional button interface. Instead of only vertical pressing actions on physical buttons, users can perform various touch gestures (tap, swipe, pinch, etc.) on the display surface, expanding the available control methods without adding physical components.
3Adaptability or versatility
If editing functions are embedded in menu hierarchies, then comprehensive edit capabilities are provided, but the editing process becomes time-consuming and requires memorization
Solution Approach 1:
The patent displays edit-related controls and options directly on the touch-sensitive display in proximity to the content being edited. By preparing and presenting these editing tools in advance and in visible locations, users can access editing functions immediately without needing to navigate through menu hierarchies or memorize command sequences.
Solution Approach 2:
The patent extracts editing functions from deep within menu hierarchies and places them directly on the display interface where users can access them immediately. This extraction brings previously hidden or hard-to-reach editing capabilities into direct view and easy reach, eliminating the time required to navigate through multiple menu levels.
4Volume of moving object
If the device is made more compact, then portability is improved, but the screen size decreases making interaction more difficult
Solution Approach 1:
The patent merges the display surface with the input control interface. By making the entire touch-sensitive display area responsive to user input, the device eliminates the need for separate physical controls that would occupy additional space. This integration allows compact device design while maintaining ease of interaction through direct touch on the display surface.

AI summary
Methods and graphical user interfaces for editing on a portable multifunction device with a touch screen display are disclosed. While displaying an application interface of an application, the device detects a multitouch edit initiation gesture on the touch screen display. In response to detection of the multitouch edit initiation gesture, the device displays a plurality of user-selectable edit option icons in an area of the touch screen display that is independent of a location of the multitouch edit initiation gesture. The device also displays a start point object and an end point object to select content displayed by the application in the application interface.
