Solution Overview

Problem

Existing methods for electronic payments at a point of sale (POS) using smart devices are insecure due to the visibility of hand movements, which can be mimicked by others to gain unauthorized access.

Innovation Solution

Utilizing smart glasses with eye tracking technology to enable select, hold, drag, and drop functionality in augmented reality, allowing users to perform electronic payments hands-free by focusing their eyes on specific objects and maintaining focus for predetermined durations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If hand movements are used to select payment method and enter password, then ease of operation is improved, but security is worsened due to visibility of actions to others

Engineering Contradiction:
Improveease of operationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical operations (hand movements for typing and selection) with an optical control system (eye tracking). The eye tracking system detects gaze direction and fixation duration to control the payment interface, substituting the mechanical hand-based interaction with an optical-based biometric control mechanism that is not visible to observers.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If eye tracking is used to select payment method and enter password, then security is improved by making actions invisible, but device complexity is worsened

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The smart glasses device integrates multiple functions into a single platform: augmented reality display for showing payment options, eye tracking system for detection, and processing capabilities for executing payments. This multi-functional integration allows the same device to handle display, input detection, and payment processing, reducing the need for separate devices while maintaining security.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If predetermined duration focus is required for selection, then security is improved by preventing accidental selection, but productivity is worsened due to longer interaction time

Engineering Contradiction:
ImprovesecurityVSAvoidproductivity
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system uses periodic sampling of eye position data over time to detect fixation events. Instead of continuous monitoring, the system checks eye position at regular intervals and determines whether the gaze has remained on a target object for the predetermined duration threshold. This periodic detection approach balances security requirements with operational efficiency.

Inventive Principle:
Principle #19Periodic action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This approach enhances security and convenience by making electronic payments more difficult to intercept or mimic, as eye movements are not visible to others, and allows for hands-free operation at the POS.

AI summary

A QR code may be viewed with smart glasses having an eye tracker. The QR code may be selected by a user focusing on the QR code. The QR code may be captured. The captured QR code may trigger a display on the lens of an object, such as a selector, a bill payment method, or a keypad, or a web page. A user may select and hold a selector object at a first position by focusing on it. Subsequent eye movement may drag the selector object to a new position. A payment method may be selected when the selector object is dropped at the new position having a payment method object. A payment method may be alternatively selected when the user focuses directly on the payment method object. A password may be entered on a keypad or keyboard shown on the lens using eye tracking.
