Mobile Payment Card Selection by Touch Gestures and Motion Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile payment systems face issues with unauthorized copying and use of payment means, leading to complex authentication procedures that inconvenience users, and lack a simple and convenient user interface for selecting payment methods.
Innovation Solution
A mobile terminal equipped with a wireless communication unit for short-range communication, a touchscreen for gesture recognition, and a controller to initiate and maintain communication based on sensed touch or motion gestures, along with features to automatically activate applications and settings based on location, time, and ambient light, ensuring secure and convenient payment transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If strict authentication procedures are implemented to prevent unauthorized payment, then payment security is improved, but user interface complexity increases causing inconvenience
Solution Approach 1:
The authentication process is segmented into multiple independent verification steps: gesture recognition, payment method selection confirmation, and transaction authorization. Each segment handles a specific aspect of security, allowing the system to maintain high security requirements while presenting a manageable, step-by-step interface to users rather than a single complex authentication barrier.
2Adaptability or versatility
If multiple payment methods are supported, then payment versatility is improved, but user interface complexity increases making selection difficult
Solution Approach 1:
The system performs preliminary actions by automatically detecting the user's intended payment method through gesture recognition before the actual payment transaction. The gesture-based selection mechanism pre-establishes which payment method will be used, eliminating the need for users to navigate through multiple payment options during the transaction process, thus maintaining versatility while simplifying the user interface.
3Ease of operation
If gesture-based control is implemented, then operation simplicity is improved, but authentication reliability may be compromised
Solution Approach 1:
The system merges multiple authentication factors into a unified gesture-based authentication mechanism. Instead of relying on a single security check, it combines gesture pattern recognition, device state verification, and payment method confirmation into one integrated process. This allows the system to maintain simple gesture-based operation while compensating for individual gesture security limitations through the combined strength of multiple verification layers.

AI summary
A mobile terminal and controlling method thereof are disclosed, which facilitates a terminal to be used in further consideration of user's convenience. According to at least one of embodiments of the present invention, a strict authentication procedure for expense payment can be performed via a simple and convenient user interface between a mobile terminal and a terminal user. In particular, since at least one of a selection and authentication of a payment means of the mobile terminal can be performed via at least one of an aligned direction, a moving direction and a moving track of the mobile terminal, the user interface between the mobile terminal and the terminal user for the expense payment can be further simplified.
