Mirrored Interaction Area for One-Handed Touchscreen Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large touch screen terminals are difficult to operate with one hand, requiring frequent adjustments in hand position, which can lead to inconvenience and risk of the device falling, and existing one-handed modes either reduce interface proportion or complicate operations with floating cursors.
Innovation Solution
A method that involves receiving a touch operation in a target area of the screen, acquiring an interaction area with functional elements outside this area, and mirroring this interaction area at the target touch position, allowing for direct access and operation of distant elements without changing the interface proportion or hand position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large touch screen is used to provide rich visual experience, then the visual quality is improved, but the ease of operation deteriorates due to difficulty in accessing distant areas with one hand
Solution Approach 1:
The patent creates a virtual copy of the interaction area containing functional elements and positions it at the target touch area. This virtual copy allows users to access distant functional elements through a nearby touch area, resolving the contradiction between large screen visual quality and one-handed operation convenience.
Solution Approach 2:
The patent introduces a virtual interaction area as an intermediary between the user's thumb and the distant functional elements on the large screen. This intermediary virtual area enables indirect access to distant elements through local touch operations, solving the accessibility problem while preserving the large screen's visual advantages.
2Ease of operation
If existing one-handed modes reduce interface proportion, then the ease of operation is improved, but the visual experience deteriorates due to loss of original interface layout
Solution Approach 1:
The patent segments the screen into a display area showing the original interface and a virtual interaction area providing accessible functional elements. This segmentation allows the original interface to maintain its full size and visual quality while the virtual area provides operation convenience, resolving the contradiction between visual experience and ease of operation.
Solution Approach 2:
The patent adds a virtual dimension layer over the physical screen, creating a virtual interaction area that overlays the display area. This dimensional approach allows both the original high-quality visual display and the simplified one-handed interaction to coexist without compromising either aspect.
3Ease of operation
If existing one-handed modes use floating cursors, then the ease of operation is improved, but the device complexity increases due to additional interaction mechanisms
Solution Approach 1:
The patent makes the virtual interaction area respond directly to touch operations within the target area, eliminating the need for separate cursor control mechanisms. The system serves itself by directly mapping touch inputs to virtual area interactions, reducing complexity while maintaining one-handed operation convenience.

AI summary
The present disclosure relates to an interface operation method, terminal, and storage medium. The interface operation method includes: receiving a touch operation in a target touch area of the touch display screen; acquiring an interaction area with at least one target functional element in a current interface, wherein the interaction area is an area of the touch display screen outside the target touch area; and mirroring the interaction area at the target touch area in the current interface. In the single-handed operation mode, the terminal can mirror the interaction area with at least one functional element at the target touch area.
