Split Virtual Keyboard Layout for Large Screen Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen electronic devices with virtual keyboards require users to move their fingers over a larger range to input text, leading to a poor user experience due to the increased distance between virtual keys and the device's edges.
Innovation Solution
A display method for a virtual keyboard that splits the keyboard into two parts, adjusts their widths, and positions them close to the device's boundaries, reducing the distance between virtual keys and the edges, thereby improving accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the virtual keyboard is displayed on a large-screen electronic device, then the visual display quality is improved, but the distance between virtual keys and the device edges increases, making text input less convenient
Solution Approach 1:
The virtual keyboard is divided into a first virtual keyboard and a second virtual keyboard, which are displayed in different regions of the screen. This segmentation allows each keyboard to be positioned closer to the respective edge, reducing the distance from virtual keys to edges while maintaining overall visual quality on the large screen.
Solution Approach 2:
The patent utilizes the spatial dimension of the large screen by displaying two virtual keyboards in different regions rather than one centralized keyboard. This dimensional approach allows optimization of key accessibility while preserving the benefits of the large display area.
2Device complexity
If the virtual keyboard occupies the center region of the screen, then the keyboard layout is simplified, but the virtual keys are positioned far from the device edges, requiring users to move fingers over a large range
Solution Approach 1:
The virtual keyboard is segmented into two separate keyboards displayed in different regions. This segmentation resolves the contradiction by allowing each keyboard to be positioned near edges for easier access, while the overall system maintains a simple and intuitive layout that users can quickly adapt to.
3Device complexity
If the virtual keyboard is displayed in a single region, then the interface is simple, but the distance from virtual keys to device edges is large, reducing input efficiency
Solution Approach 1:
The interface is segmented to display two virtual keyboards in different regions, which improves text input efficiency by reducing finger movement distance while maintaining interface simplicity through consistent and intuitive display patterns that users can quickly learn.
Solution Approach 2:
The patent utilizes spatial distribution across different screen regions to improve input efficiency without significantly increasing interface complexity. By strategically positioning keyboards in different dimensions of the screen space, the system achieves better ergonomics while preserving interface clarity.

AI summary
A display method for a virtual keyboard and an electronic device and a storage medium are provided. The display method includes: displaying the virtual keyboard on an interface; determining, in response to a split operation for the virtual keyboard, a region where virtual keys of a first part of the virtual keyboard are located as a first key region, and a region where virtual keys of a second part of the virtual keyboard are located as a second key region; and adjusting the first key region and the second key region and displaying a functional region between the first key region and the second key region.
