Terminal Gesture Recognition via Screen Gap for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen terminals pose challenges for one-handed operations due to limited intersection areas on the screen, making it difficult for users to access functions and panels efficiently.
Innovation Solution
A terminal operating method that recognizes user inputs by generating contacts on the screen interface, specifically at gaps between the bottom edge and function identifiers, forming preset gesture tracks to display corresponding function interfaces, enhancing one-handed operation by distinguishing between operation modes and preventing misoperations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the terminal screen size is increased to provide better visual experience, then the display area is improved, but the ease of one-handed operation deteriorates due to limited intersection area coverage
Solution Approach 1:
The invention segments the screen interface into distinct functional zones: a first area containing function identifiers and a second area containing operation panels. By defining a specific gap area between these segments, the system creates dedicated one-hand operation zones that are accessible from either hand position, effectively segmenting the interaction space to match human ergonomics while preserving the large display area.
2Ease of operation
If all function objects are arranged in the limited intersection area, then the ease of one-handed operation is improved, but the display area and function identifier visibility deteriorate
Solution Approach 1:
The invention transitions from a two-dimensional arrangement where all functions must fit in the intersection area to a multi-dimensional layout. Function identifiers are positioned in a first area while operation panels are placed in a second area, with the gap between them serving as the one-hand operation zone. This spatial reorganization allows full-screen utilization while maintaining ergonomic accessibility.
3Ease of operation
If the gesture track is defined to enable one-hand operation, then the ease of operation is improved, but the risk of misoperation increases due to potential confusion with other operation modes
Solution Approach 1:
The invention applies local quality by defining specific characteristics for the gap area that distinguish it from other screen regions. The gap area is positioned between function identifiers and operation panels, creating a unique spatial signature. When a touch gesture originates from this specific location, the system recognizes it as a one-hand operation mode, while gestures from other areas trigger different operations, thereby preventing misoperation through location-specific gesture recognition.

AI summary
The present invention provides a terminal operating method. The method comprises: generating at least one contact on a screen interface of a terminal; and if the at least one contact is located at a gap between a bottom edge of the screen interface of the terminal and a function identifier displayed on the screen interface and a preset gesture track is formed by using the contact as a start point, displaying a preset functional interface on the screen interface. The present invention also provides a terminal. By using the technical solutions of the present invention, operations of a user can be accurately recognized by means of a gap or a slit on a screen interface of a terminal, so that the method is more applicable to one-hand operations of a large-screen terminal.
