Contactless Payment Interface Using Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contactless payment systems using NFC technology are limited by the need for close proximity, which violates social distancing guidelines, and the process of entering a PIN or authenticating users can be tedious and time-consuming, hindering the convenience of mobile payments.
Innovation Solution
A contactless human-to-device interface system that utilizes a user expression map to enable real-time image data processing for gesture and gaze recognition, allowing users to perform transactions by associating specific expressions with control events, such as payments or tips, without the need for physical proximity or manual authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC technology is used for contactless payments, then payment security and reliability are improved, but the requirement for close proximity (within two inches) violates social distancing guidelines
Solution Approach 1:
The patent replaces the mechanical proximity-based NFC system with an optical system using cameras and image processing to detect gestures and gaze direction. This substitution allows contactless payment initiation from a distance while maintaining security through biometric-like verification of user intent via expressed gestures.
2Reliability
If manual authentication procedures (entering PIN, adding tips) are implemented, then transaction security and control are improved, but the process becomes tedious and time-consuming
Solution Approach 1:
The system enables users to authenticate and control transactions through natural self-service gestures captured by the camera. Users express payment intent, tip amounts, and authentication through intuitive hand gestures and gaze direction, eliminating the need for manual PIN entry or interaction with physical keypads, thereby reducing authentication time while maintaining security.
Solution Approach 2:
The user expression map is pre-configured with gesture-to-action mappings before the transaction occurs. This preliminary setup allows the system to instantly interpret gestures during the transaction without requiring real-time processing or manual input, significantly reducing authentication time while maintaining precise transaction control.
3Ease of operation
If traditional contactless payment interfaces are used, then ease of operation is improved for close-range users, but the system fails to accommodate social distancing requirements
Solution Approach 1:
The patent transitions from two-dimensional touchscreen or close-range NFC interaction to three-dimensional spatial interaction using gesture recognition and gaze tracking. This dimensional change allows users to operate the payment system from a distance by expressing intent through body movements and eye direction, maintaining ease of operation while accommodating social distancing.
Data Source
AI summary
Systems, apparatuses, methods, and computer program products are disclosed for facilitating contactless and socially distant payments. Specifically, certain embodiments are configured for generating and utilizing a user expression map for associating user expressions to control events. The methods further correspond to receiving, in real-time, image data representative of at least a portion of a user body, the user body tracked by a contactless human to device interface system. The methods further include causing a retrieval of a user expression map from a first computing device for provision to a second computing device, determining using the user expression map, that the image data is associated with a control event indicative of a directive to perform a particular transaction, and triggering the control event to cause performance of the particular transaction based, at least in part on the determination that the image data is associated with the control event.
