Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resource dispensing systems require physical interaction for user authentication, such as entering a PIN at a resource dispensing terminal, which is cumbersome and lacks a seamless and hygienic solution.
Innovation Solution
A system that enables touchless authentication by using image and video data analysis to recognize user gestures at a distance from the terminal, employing sensors like video, camera, and infrared sensors to validate user inputs without physical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical interaction is required for authentication (entering PIN at terminal), then authentication security is maintained, but user convenience and hygiene are degraded
Solution Approach 1:
The patent replaces the mechanical system of physical keypresses with an optical sensing system. Cameras and image sensors capture visual data of finger presses on the keypad, while infrared sensors detect thermal signatures. This substitution eliminates the need for physical contact between the user and the terminal, resolving the contradiction by maintaining authentication functionality while improving hygiene and convenience.
Solution Approach 2:
The patent introduces an intermediary layer of sensing technology between the user and the authentication system. Instead of direct physical interaction, the system uses cameras, image sensors, and infrared sensors as intermediaries to detect and verify user inputs. This intermediary mechanism allows authentication to proceed without direct contact, addressing both convenience and hygiene concerns.
2Ease of operation
If touchless gesture recognition is implemented, then user convenience and hygiene are improved, but system complexity increases
Solution Approach 1:
The patent employs multi-functional sensors that can perform multiple tasks. Cameras and image sensors not only capture gesture data but can also verify identity through facial recognition or other biometric methods. Infrared sensors can detect both thermal signatures for authentication and presence detection. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while enabling touchless operation.
Solution Approach 2:
The patent combines multiple sensing modalities (visual cameras, image sensors, infrared sensors) into an integrated authentication system. By merging these different sensing approaches, the system achieves robust touchless gesture recognition and authentication capabilities without requiring entirely separate systems for each function, thus managing complexity through integration.
3Measurement precision
If multiple sensors are deployed for gesture recognition, then authentication accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent utilizes different physical parameters detected by various sensors to complement each other. Cameras capture visual parameters of gesture movement and position, image sensors detect reflected light patterns, and infrared sensors measure thermal parameters. By changing and combining multiple detection parameters, the system achieves high gesture recognition accuracy while managing complexity through the use of complementary sensing approaches.
