Garment Identifier Controller for Secure Biometric Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable devices, such as smart clothing, are limited in their ability to control external devices using biosignal data, often requiring direct user input or local communication, which can be inconvenient and insecure.
Innovation Solution
A controller system that obtains an identifier from a wearable garment, uses this identifier to retrieve a biometric identity from biosignal data, and determines the operational mode of a device based on this identity, allowing for secure and user-specific control of devices without direct biosignal data access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If biosignal data is used directly for device control, then user-specific control capability is improved, but system complexity and security requirements increase
Solution Approach 1:
The patent introduces an intermediary system comprising a server and database that mediates between the wearable garment and the controlled device. The server receives biosignal data from the garment, processes it to determine operational modes, and sends control commands to the device. This intermediary architecture allows user-specific control without requiring the device itself to have complex biosignal processing capabilities, thus resolving the contradiction between adaptability and device complexity.
2Reliability
If direct pairing between garment and device is implemented, then communication reliability is improved, but user flexibility and convenience deteriorate
Solution Approach 1:
The server acts as a universal communication hub that can receive data from multiple different garments and send commands to multiple different devices. Instead of requiring direct one-to-one pairing between specific garments and devices, the server provides a many-to-many communication architecture. This allows users to flexibly use different garments with different devices while maintaining reliable communication through the centralized server infrastructure.
3Speed
If biosignal data is processed locally in the device, then response time is improved, but device power consumption and complexity increase
Solution Approach 1:
The patent extracts the computationally intensive biosignal processing function from the device and relocates it to the server infrastructure. The device only needs to communicate control commands and receive feedback, while the server performs the complex analysis of biosignal data to determine operational modes. This extraction of processing responsibilities significantly reduces the power consumption and computational requirements of the device while maintaining appropriate response times through the server's processing capability.

AI summary
A controller (161) for a device (16) comprises an identifier obtaining module (165) arranged to obtain an identifier for a garment worn by a user. The controller (161) comprises a biometric module (167) arranged to use the identifier to obtain a biometric identity for the user wearing the identified garment and determine an operational mode for the device (16) from the biometric identity. A command generation module (169) is operable to generate a control command for controlling the device (16) based on the operational mode. The biometric module (167) may determine whether the user identified by the biometric identity is authorised to operate the device (16). The control command may be generated based on this determination.
