Touch Screen Mapping for Single-Handed Upper Region Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating touch screens with larger sizes on mobile devices using a single hand is challenging due to the difficulty in accessing upper portions of the screen without shrinking or moving content, as existing methods either pull down the upper half or shrink the screen proportionally.
Innovation Solution
A method and device that divide the touch screen into non-overlapping areas, allowing users to perform operations in one area while affecting corresponding points in another area, enabling easier access to upper screen regions without content manipulation, through a mapping mode that can be enabled by specific gestures or actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the screen size is increased to improve display effect, then the display quality is improved, but the ease of operation with single hand deteriorates
Solution Approach 1:
The touch screen is divided into multiple regions (first area and second area) with different operational characteristics. The first area responds directly to touch operations, while the second area is controlled through mapping from the first area, enabling differentiated interaction zones that improve single-handed operability on large screens
Solution Approach 2:
A mapping mechanism is introduced as an intermediary between the user's touch operations in the first area and the actual control targets in the second area. This mapping relationship allows users to operate from a convenient location while affecting controls in another location, resolving the accessibility issue on large screens
2Ease of operation
If the upper half of the screen is pulled down to enable operation, then the accessibility to upper screen is improved, but the screen content arrangement deteriorates
Solution Approach 1:
Instead of physically moving or duplicating screen content, the patent creates a virtual copy of the control interface in the second area that responds to touch operations in the first area. This virtual copying allows users to access upper screen functions from the lower area without altering the actual content arrangement
3Ease of operation
If the screen is shrunk to enable single-handed operation, then the ease of operation is improved, but the display quality deteriorates
Solution Approach 1:
The patent applies different operational qualities to different areas of the screen. The first area is designed for easy single-handed access, while the second area maintains full display quality. The mapping mechanism allows the system to provide localized interaction benefits without compromising overall display quality

AI summary
This disclosure discloses a device and method for operating on a touch screen, and a storage medium. The device includes one or more processors and a memory, the one or more processors are configured to perform: determining a target touched point in a first area of the touch screen according to a sliding operation or a clicking operation by a user in the first area; determining a target mapped point in a second area of the touch screen, corresponding to the target touched point in the first area; and if it is determined that the user needs to click on the target mapped point, then clicking on the target touched point in the first area, corresponding to the target mapped point in the second area to thereby click on the target mapped point, wherein the first area and the second area do not overlap with each other.
