Touchscreen Interface Content Display via Moving Track Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complexity in viewing details of content on terminal device screens, such as small images or videos, requiring repetitive operations to enlarge or pause playback.
Innovation Solution
A method and apparatus that dynamically display interface content by monitoring touch object coordinates on a touchscreen, determining control parameters based on preset relationships, and displaying content accordingly, allowing users to view required content with simple operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users perform complex operations to view content details, then content visibility is improved, but operation complexity increases
Solution Approach 1:
The system automatically detects the user's viewing intent through touch screen interaction and autonomously adjusts the display parameters (enlargement, positioning, video playback control) without requiring the user to manually perform complex operations. The touch object's moving track serves as implicit input that triggers automated content adjustment.
Solution Approach 2:
The touch object acts as an intermediary between the user and the content display system. By tracking the moving track of the touch object, the system translates simple user gestures into complex display adjustments, eliminating the need for users to directly manipulate content details.
2Loss of information
If interface content is displayed in detail, then content visibility is improved, but device complexity increases
Solution Approach 1:
The interface dynamically adjusts content display parameters based on the real-time position and moving track of the touch object. The system transitions between different display states (normal view, enlarged view, video playback control) according to user interaction, providing detailed content viewability without requiring a complex static interface design.
3Measurement precision
If video playback is controlled through repetitive operations, then playback control precision is improved, but time consumption increases
Solution Approach 1:
The system automatically controls video playback based on the touch object's moving track, detecting user intent to pause, replay, or seek specific frames without requiring repetitive manual operations. The system self-adjusts playback state according to interaction patterns.
Solution Approach 2:
The system pre-processes the touch object's moving track to anticipate user playback control needs, enabling seamless transitions between playback states and reducing the time required for frame-by-frame analysis or replay operations.

AI summary
Aspects of the disclosure provide methods and apparatuses for displaying interface content. In an example, processing circuitry detects a moving track of a touch object on a touch screen of a terminal device. The moving track is represented by coordinates of the touch object varying along the moving track. Then, the processing circuitry determines, based on a preset relationship of the moving track and a control parameter for a control object on a user interface, a value of the control parameter for the control object that varies with the coordinates of the touch object along the moving track. The control object has content that is displayed on the touch screen. Further, the processing circuitry displays, on the touch screen, the content of the control object on the user interface according to the value of the control parameter that varies with the coordinates of the touch object along the moving track.
