Mobile Payment Interface Triggered by Body Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile payment methods are inconvenient as they require users to unlock their devices and navigate through multiple steps to access the payment interface, making the process cumbersome.
Innovation Solution
A terminal device monitors user body movements in lock screen mode and displays a mobile payment interface when specific criteria are met, allowing users to execute payments without unlocking the screen or starting a specific application, using a monitoring module, display module, and execution module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user unlocks the screen and starts a specified application to perform mobile payment, then the payment security is ensured, but the operation steps increase and convenience decreases
Solution Approach 1:
The system pre-loads the payment interface and prepares the payment environment in advance, so that when the user performs the body movement, the payment interface can be displayed immediately without requiring the user to unlock the screen and navigate through multiple applications. The payment application is kept in memory and the interface is pre-configured, enabling rapid access.
Solution Approach 2:
The payment interface is extracted from the locked application environment and made accessible through a separate trigger mechanism (body movement). This allows the payment functionality to be accessed independently of the normal application launching process, bypassing the need to unlock the screen while maintaining security through biometric authentication.
2Reliability
If the user unlocks the screen through fingerprint verification or password input, then the device security is maintained, but the time consumption increases
Solution Approach 1:
The system performs preliminary authentication by detecting the user's body movement pattern, which serves as a pre-authentication step. When the characteristic body movement is detected, the system has already verified the user's identity and can immediately display the payment interface without requiring additional authentication steps like fingerprint verification or password input.
Solution Approach 2:
The system skips the traditional authentication steps (screen unlocking, application launching) by using body movement recognition as a direct trigger. The authentication and interface display processes are rushed through in a single automated sequence, reducing the overall time from initiation to payment interface display.
3Ease of operation
If the system monitors body movements and displays payment interface directly, then the operation convenience is improved, but the risk of unauthorized access may increase
Solution Approach 1:
The system continuously monitors body movements and provides feedback by comparing the detected movement against stored characteristic movement patterns. Only when the monitored movement matches the predetermined pattern does the system trigger the payment interface. This feedback mechanism ensures that only authorized users with the specific body movement pattern can access the payment function.
Solution Approach 2:
The system applies different quality requirements to different aspects of the authentication process. The body movement recognition uses specific local characteristics (movement pattern, speed, trajectory) rather than general presence detection. This localized quality control enhances security by requiring a specific, difficult-to-replicate movement pattern while maintaining operational simplicity.

AI summary
Implementations of the present specification disclose mobile payment methods, apparatuses, and devices. In one aspect, the method includes: monitoring, by a terminal device that is in lock screen mode, outputs of one or more sensors of the terminal device; determining that the outputs of the one or more sensors satisfy first specified criteria indicative of one or more particular body movements; in response to determining that the outputs of the one or more sensors satisfy the first specified criteria, displaying, on the terminal device, a payment processing interface; receiving an input through the payment processing interface; and executing a payment service based on the input.
