Touchscreen Gesture Table Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device interactions using touchscreens are often limited by non-intuitive interfaces, particularly when recreating desktop applications, leading to inefficiencies and user unfriendliness as applications gain functionality.
Innovation Solution
Implementing a method where users can create tables in electronic documents on touchscreens by detecting specific gestures, such as drawing a rectangle and subdividing it into quadrants, to automatically generate and insert tables, allowing for intuitive expansion of table rows and columns through edge interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional desktop application interfaces are recreated on mobile touchscreens using buttons and menus, then application functionality can be maintained, but user interaction becomes non-intuitive and operationally complex
Solution Approach 1:
The patent replaces traditional mechanical interface elements (buttons, menus, keyboards) with touchscreen gesture-based interaction. Users create tables by drawing gestures directly on the screen, substituting the mechanical clicking and menu-navigating with intuitive visual drawing actions that map naturally to the desired outcome.
Solution Approach 2:
The system allows users to directly create and manipulate table structures through their own gestures without requiring the system to present pre-defined options or menus. The gesture recognition system interprets user drawings and automatically generates the corresponding table structure, enabling users to serve themselves rather than being served by fixed interface options.
2Manufacturing precision
If complex menu systems are used to create tables on mobile devices, then precise control over table creation is achieved, but the number of steps and interface complexity increases
Solution Approach 1:
The patent extracts the essential table creation function from complex menu systems and implements it through simple gesture drawing. Instead of requiring users to navigate through multiple menu levels and configuration options, the system captures only the necessary information from the user's gesture (position, size, orientation) and directly creates the table structure.
Solution Approach 2:
Rather than presenting users with pre-defined table creation options and requiring them to select and configure, the patent inverts the approach by having users draw their desired table structure directly and having the system interpret and fulfill that drawing. This reverses the traditional menu-driven paradigm.
3Measurement precision
If physical keyboards and buttons are used for mobile device input, then precise text and command input is achieved, but the device portability and touchscreen integration are compromised
Solution Approach 1:
The patent makes the touchscreen serve multiple functions: it acts as both the display surface and the input mechanism. The same screen that shows content also receives gestures for creating and manipulating tables, eliminating the need for separate physical input devices and maximizing the utility of the touchscreen interface.

AI summary
A method comprising displaying, on a touchscreen, a digital electronic document; receiving first input from the touchscreen and determining that the first input comprises a rectangle gesture; receiving second input from the touchscreen and determining that the second input comprises a subdivision gesture that indicates dividing the rectangle; determining that the first input and the second input have been received within a time threshold; in response to determining that the first input and second input have been received within the time threshold, automatically generating a table that comprises a plurality of cells; automatically placing the table in the document at a location that is based on the first input and updating the document that is displayed on the touchscreen to visually show the table; wherein the method is performed by one or more computing devices.
