Transparent Virtual Keyboard Touch Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of virtual keyboards on mobile terminals is hindered by the need for frequent switching between keyboard and page operations, leading to increased user complexity due to the occupation of large screen areas and insufficient display space.
Innovation Solution
A method and terminal that determine the operation object on a touch screen, allowing direct operation on either the page content or the virtual keyboard without additional switching, by analyzing touch points and durations to differentiate valid from invalid inputting, and adjusting transparency accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a virtual keyboard is displayed on the screen, then inputting function is improved, but the viewable screen area is decreased
Solution Approach 1:
The patent applies transparency changes to the virtual keyboard, making it partially transparent when not in active input mode. This allows the keyboard to remain visible on screen without completely blocking the underlying content, thus maintaining both input functionality and screen visibility simultaneously.
2Ease of operation
If the virtual keyboard occupies large screen area for ease of input, then inputting ease is improved, but display space is insufficient
Solution Approach 1:
The patent implements dynamic transparency adjustment of the virtual keyboard based on operational context. When the keyboard is the active input target, it becomes opaque for clarity; when the underlying page content is the target, the keyboard becomes transparent. This dynamic adaptation allows the keyboard to optimize for its current function while minimizing interference with display space.
3Adaptability or versatility
If frequent switching between keyboard mode and page mode is required, then operation flexibility is improved, but user interaction complexity increases
Solution Approach 1:
The system automatically determines whether the user intends to input through the keyboard or interact with the page content by analyzing touch operation characteristics (such as touch position, duration, and pattern). This eliminates the need for users to manually switch between keyboard mode and page mode, as the system adapts to user intent automatically, reducing interaction complexity while maintaining operational flexibility.

AI summary
Embodiments of the present invention provide a method and terminal for operating through a touch screen. The method includes: after a transparent virtual keyboard is displayed, receiving a first operation for a display area of the transparent virtual keyboard through a touch screen; determining, according to the first operation, that a target object of the first operation is a page content in the display area of the transparent virtual keyboard; and performing the first operation for the page content in the display area of the transparent virtual keyboard. Therefore, the operation may be directly performed for the determined target object. Therefore, no additional operation is required to perform switching between the transparent virtual keyboard and the page, thereby reducing user operations and improving the user experience.
