Multi-Window Touch Control via Transparent Background Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-window systems on touch devices, the limited touch area makes it inconvenient for users to accurately interact with windows due to overlapping screens, particularly when trying to resize or close them.
Innovation Solution
The method involves detecting touch points on title bars of windows and interpreting specific touch gestures to execute window control commands, such as resizing, maximizing, minimizing, and closing, using a controller connected to the touch interface, allowing users to easily operate windows by touching the title bar and performing gestures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple windows are displayed on a touch device with limited touch area, then the device can handle more tasks simultaneously, but the windows may overlap each other making it inconvenient for the user to touch the edge or control buttons of a certain window
Solution Approach 1:
The patent extends the window control interaction from the traditional 2D window boundary area to the entire screen space by detecting touch gestures on the transparent background layer. This dimensional extension allows users to control windows regardless of their position or overlap state, resolving the contradiction between displaying multiple windows and maintaining ease of operation.
Solution Approach 2:
The patent introduces a transparent background layer as an intermediary between the user's touch input and the window control system. This background layer captures touch gestures that occur in the negative space between windows and translates them into window control commands, enabling window manipulation without requiring direct contact with the window's visible boundaries.
2Area of stationary object
If the touch area of the touch device is limited, then the device maintains portability, but multiple windows may overlap each other making it inconvenient for the user to touch the edge or cancel button of a certain window
Solution Approach 1:
The patent transforms the window control interaction from being confined to the 2D window boundary area to utilizing the entire screen area through the transparent background layer. This allows the limited touch screen area to effectively control multiple overlapping windows by interpreting gestures in the negative space between them.
Solution Approach 2:
The transparent background layer serves multiple functions: it acts as a gesture recognition surface, a window control interface, and a spatial organizer. By making the background functional, the system allows any area of the screen to participate in window control, maximizing the utility of the limited touch screen area.

AI summary
An electronic device and a method are adapted to identify window control commands in a multi-window system. The electronic device displays multiple windows each respectively having a title bar on a touch interface. The electronic device executes the method to identify a window control command according to a touch gesture from a movement of a touch point detected on the title bar of one of the windows. The user can easily touch the title bar to operate a certain window.
