Mobile Terminal Control Window for One-Handed Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals face challenges in providing intuitive and efficient user interaction due to the increasing complexity of functions and larger display sizes, making it difficult for users to perform manipulations on touch screens with limited finger reach.
Innovation Solution
The mobile terminal employs a control window that dynamically adjusts its position and size based on the position and trace of a touch action, allowing one-handed operation by distinguishing between central and edge areas of the screen and optimizing user interface elements for efficient touch input.

Engineering Contradiction Analysis
1Area of stationary object
If the display screen size is increased to show more information, then the information representation capability is improved, but the ease of operation deteriorates due to limited finger reach
Solution Approach 1:
The display screen is divided into multiple interaction zones (first area and second area) with different interaction modes. The first area responds to single touch inputs while the second area responds to multi-touch inputs, allowing the large screen to be segmented into manageable interaction regions that are easier to operate within reach
Solution Approach 2:
The system dynamically adjusts its behavior based on the number of touch points detected. When one touch point is detected, the system activates first interaction mode; when multiple touch points are detected, it switches to second interaction mode. This dynamic adaptation allows the large screen to respond appropriately to different user gestures within reachable areas
2Adaptability or versatility
If the number of functions in the terminal is increased to enhance capabilities, then the functionality is improved, but the device complexity increases
Solution Approach 1:
The touch screen serves multiple functions by detecting different numbers of touch points and triggering different interaction modes. The same hardware interface handles both single-touch and multi-touch operations, providing universal functionality without requiring separate hardware components for different features
Solution Approach 2:
The system changes its operational parameters based on the detected touch pattern. By monitoring the number of touch points and adjusting the interaction mode accordingly, the terminal achieves versatile functionality through parameter changes rather than through complex structural modifications

AI summary
A mobile terminal and a control method thereof are disclosed. The mobile terminal includes: a touch screen configured to acquire a user's touch action; and a controller configured to display a control window for performing manipulations on content displayed on the touch screen, based on at least either one of the position and trace of the acquired touch action. Accordingly, the mobile terminal can be manipulated more easily by displaying a control window for performing manipulations on content displayed on a touch screen, based on at least either one of the position and trace of a touch action.
