Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window management systems on touch-screen devices lack intuitive and efficient methods for resizing and arranging windows using multi-touch gestures, limiting user interaction and flexibility in managing display space.
Innovation Solution
A window manager that interprets multi-touch gestures to resize, maximize, minimize, and reposition windows based on the direction and speed of user input, allowing alignment with a grid for precise placement and behavior control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional single-touch or click-based window management is used, then the system is simple to implement, but the user interaction is not intuitive and flexibility in managing display space is limited
Solution Approach 1:
The patent replaces traditional mechanical click-based window management with touch-based gesture recognition. Multi-touch gestures (swiping, pinching, rotating) substitute for mouse clicks and drag operations, providing more intuitive direct manipulation of windows on touch-screen devices while maintaining system manageability through gesture-based control mechanisms.
Solution Approach 2:
The window management system transitions from static window positioning to dynamic gesture-responsive positioning. Windows can be resized, moved, and arranged in real-time based on continuous multi-touch gestures, allowing flexible display space management that adapts to user intent through gesture direction, speed, and duration.
2Adaptability or versatility
If multi-touch gesture recognition is implemented for window management, then user interaction becomes more intuitive and flexible, but the system complexity increases
Solution Approach 1:
The window manager implements a universal gesture recognition system that handles multiple window management operations (resizing, moving, maximizing, minimizing) through a single multi-touch interface paradigm. The same multi-touch gesture framework supports various gestures (swipe directions, pinch magnitude, rotation angle) to perform different window operations, reducing the need for separate control mechanisms.
Solution Approach 2:
The system interprets different gesture parameters (number of contact points, swipe direction, swipe distance, pinch magnitude, rotation angle) to determine specific window management actions. By mapping continuous gesture parameters to discrete window operations, the system achieves high versatility while managing complexity through parameter-based gesture classification.
3Manufacturing precision
If precise grid alignment is implemented for window placement, then window arrangement precision is improved, but the complexity of placement control increases
Solution Approach 1:
The window management system implements automatic grid snapping that autonomously aligns windows to the grid based on gesture direction and magnitude. When a user drags a window, the system automatically snaps it to the nearest grid intersection, eliminating the need for manual precise positioning while maintaining high placement precision. This self-aligning mechanism reduces placement control complexity.
Solution Approach 2:
The system provides visual feedback during window dragging to indicate grid alignment points and snap positions. As the user moves a window near a grid intersection, the system highlights or snaps to the alignment point, guiding the user to precise placements without requiring complex manual adjustment. This feedback mechanism simplifies precise window arrangement.

AI summary
A computer-implemented method for tiling a window, the method comprising presenting a window of a first size in a display area of a touch-based display and receiving, via the touch-based display, a first user input indicating a selection of the window, wherein the first user input comprises an indication that the user has initiated contact with the touch-based display at a plurality of contact points. In certain aspects, the method further comprises steps for receiving, via the touch-based display, a second user input indicating a first movement of the window in a direction of a first edge of the display area and in response to the second user input and resizing a first edge of the window. Systems and computer-readable media are also provided.
