Foldable Screen Gesture Control Using Folded-Angle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional man-machine interaction modes for foldable screens are inadequate, limiting operations in the foldable area and failing to provide specialized functions, thus compromising user experience.
Innovation Solution
A gesture interaction method for foldable screens that detects user inputs on specific touch display areas, including a first, second, and third touch display area, determining the included angle and triggering corresponding operations based on input events, such as single-hand or two-hand holding, tapping, sliding, pressing, dragging, or scaling, to enhance functionality and control experience.

Engineering Contradiction Analysis
1Area of stationary object
If a foldable screen is used to increase display area, then the device functionality is enhanced, but the operation experience in the foldable area is limited
Solution Approach 1:
The patent applies local quality by implementing different interaction modes for different areas of the foldable screen. The foldable area is divided into a first interaction area (when folded angle is within the first angle range) and a second interaction area (when folded angle is within the second angle range), each with customized gesture recognition and interaction functions. This allows the system to provide area-specific optimization without compromising the overall display area benefit.
2Device complexity
If conventional interaction modes are used, then the device structure is simple, but the operation experience in foldable area is insufficient
Solution Approach 1:
The patent implements dynamics by making the interaction mode adaptive to the real-time folded state of the screen. The system dynamically switches between first and second interaction areas based on the folded angle detected by the sensor module. This dynamic adaptation allows the device to automatically adjust its interaction characteristics without requiring complex manual configuration, thereby improving operation experience while maintaining relatively simple device structure.
3Adaptability or versatility
If gesture recognition is added to the foldable area, then the functionality is enriched, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the foldable area into distinct interaction areas based on folded angle ranges. The processing module is configured to determine which interaction area is currently active and apply corresponding gesture recognition rules. This segmentation approach allows the system to implement rich functionality through modular, context-specific gesture handling rather than requiring a single complex universal gesture system.

AI summary
A gesture interaction method and apparatus are provided. The method is applied to a terminal device having a foldable screen, where the foldable screen of the terminal device in a folded state includes a first touch display area, a second touch display area, and a third touch display area, and the third touch display area is between the first touch display area and the second touch display area. The method includes: determining that an angle value of an included angle formed between the first touch display area and the second touch display area is less than a specified angle value (S601); obtaining an input event that acts on the third touch display area (S602); and triggering, in response to the input event, the terminal device to execute an operation instruction corresponding to the input event (S603). According to the method, a gesture operation that acts on a foldable area of the foldable screen of the terminal device can be responded to. This helps enrich functions of the terminal device and improve operation experience of the terminal device.
