Solution Overview
Problem
Large-screen mobile phones are difficult to control with a single hand due to the need for manual tapping to switch operation interfaces, which is not intelligent and causes operation difficulties.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual tapping is used to switch operation interfaces, then the terminal can adapt to different holding gestures, but the operation difficulty increases and the system becomes less intelligent
Solution Approach 1:
The terminal automatically detects holding gestures through capacitive sensors and self-adjusts the operation interface without requiring manual tapping. The system serves itself by autonomously identifying whether the user is holding with left hand, right hand, or both hands, and automatically switching the interface layout accordingly, eliminating the need for manual intervention.
Solution Approach 2:
The patent replaces the mechanical manual tapping operation with an automatic capacitive detection system. Instead of requiring physical tapping actions to switch interfaces, the system uses capacitive sensors to detect the electrical properties of different holding gestures and automatically adjusts the interface, substituting mechanical interaction with electrical field-based detection and automatic control.
2Adaptability or versatility
If manual tapping is required to switch interfaces, then the terminal can provide gesture-specific interfaces, but the system intelligence is insufficient
Solution Approach 1:
The terminal performs self-detection of holding gestures through capacitive sensors embedded in the housing. The system automatically identifies the holding pattern (left hand, right hand, or both hands) and self-adjusts the operation interface without requiring any manual switching actions from the user, thereby demonstrating intelligent automation.
Solution Approach 2:
The capacitive sensors continuously monitor the electrical capacitance changes caused by different holding gestures. The system uses this feedback information to dynamically adjust the operation interface in real-time, creating a closed-loop control system where the terminal responds automatically to user holding patterns, enhancing system intelligence.
3Area of stationary object
If the screen size is increased, then the display capability is improved, but the ease of single-handed control deteriorates
Solution Approach 1:
The operation interface is made dynamic by automatically reconfiguring its layout based on the detected holding gesture. When single-handed holding is detected, the system dynamically adjusts the interface to concentrate controls in the easily reachable area. This dynamic adaptation allows large screens to maintain ease of single-handed control by flexibly reorganizing the interface rather than being fixed.
Solution Approach 2:
The interface layout is optimized for local accessibility based on holding detection. When single-handed holding is detected, the system concentrates important controls and navigation elements in the region most accessible to that hand, while less critical elements are placed in less accessible areas. This local optimization ensures that essential functions remain easily controllable despite the large screen size.

AI summary
Embodiments of the present invention provide a terminal, where the terminal includes: a conductive sheet, configured to form a capacitor with a hand when the hand holds the terminal; and a processor, connected to the conductive sheet, where the processor is configured to detect a capacitance of the capacitor, and determine a holding gesture for the terminal according to the detected capacitance and a preset correspondence between a capacitance and a holding gesture. In the embodiments of the present invention, a conductive sheet is disposed in a terminal, and when a hand holds the terminal, the conductive sheet forms a capacitor with the hand. When the terminal is held by using different holding gestures, capacitances of capacitors formed between the conductive sheet in the terminal and the hand are different, and a correspondence between a capacitance and a holding gesture is preset by using this difference. Therefore, during actual detection, a holding gesture for the terminal can be determined by performing matching according to a detected capacitance of the capacitor and the preset correspondence.
