Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication methods (credit cards, passwords, PIN codes, iris recognition) are used in AR/VR environments, then authentication can be performed, but user convenience and operational efficiency deteriorate due to the immersive nature of the environment making traditional input methods difficult
Solution Approach 1:
The system enables the ring device to automatically perform authentication by gathering biometric information from the user's finger and transmitting it to the server, eliminating the need for manual input operations. The authentication process occurs passively as the user simply wears the ring, with the device autonomously completing the authentication sequence through biometric scanning and data transmission.
Solution Approach 2:
The patent replaces traditional mechanical or manual authentication methods (typing passwords, inserting cards, physical iris scanning) with a biometric sensing system that automatically reads physiological characteristics from the user's finger. This substitution eliminates the need for manual interaction while maintaining or enhancing security through unique biological identifiers.
2Reliability
If biometric sensors and tracking systems are integrated into the ring device, then authentication reliability and tracking precision improve, but device complexity and manufacturing cost increase
Solution Approach 1:
The ring device integrates multiple functions into a single compact unit: biometric information gathering through sensors, position tracking through inertial measurement units, and wireless communication through network modules. This multi-functional integration allows the device to perform authentication, tracking, and data transmission simultaneously, reducing the need for separate devices while maintaining reliability.
Solution Approach 2:
The patent embeds multiple functional components (sensors, processors, communication modules, power sources) within the confined structure of the ring device. The biometric sensors are integrated into the ring's body, with processing units and communication modules nested within, creating a compact hierarchical structure that maximizes functionality within minimal space.
Data Source
AI summary
A wearable authentication system is provided. The wearable authentication system includes a head-mounted device and a ring device. The head-mounted device includes a first network module and a camera. The first network module sends an authentication request. The camera is configured to provide an image of a hand of a user. The ring device includes an inertial measurement unit, a second network module and a biometric sensor. The inertial measurement unit provides an inertial measurement value of the ring device. The second network module receives the authentication request. The biometric sensor gathers biometric information from the user based on the authentication request. The wearable authentication system tracks a position of the ring device based on at least one of the image and the inertial measurement value. The second network module sends authentication information based on the biometric information and the inertial measurement value to the first network module.
