Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device pairing processes for secure data transfer between user devices and companion devices are cumbersome and require multiple steps, often involving manual input like typing in a PIN.
Innovation Solution
A wearable display system that includes an image capture device to capture optical patterns displayed by companion devices, extracting data from these patterns to authenticate the devices without the need for explicit user input or additional hardware on the companion device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pairing processes are used with manual input like typing in a PIN, then device authentication can be achieved, but the process becomes cumbersome and requires multiple steps
Solution Approach 1:
The patent replaces manual mechanical input (typing PINs) with an automated optical recognition system. The image capture device captures optical patterns displayed by the companion device, and the processor automatically extracts and verifies authentication data from these patterns, eliminating the need for manual keyboard input and reducing the pairing process to a simple visual confirmation.
2Reliability
If manual input methods are used for device pairing, then authentication can be performed, but the complexity and manual effort increase
Solution Approach 1:
The system performs self-service authentication by automatically capturing optical patterns, extracting authentication data, and verifying device identity without requiring user intervention. The processor autonomously completes the entire authentication workflow, from capturing the optical pattern to establishing the secure connection, thereby reducing both manual effort and perceived complexity.
3Ease of operation
If optical pattern recognition is used for authentication, then the pairing process is simplified and automated, but the system requires an image capture device and processing capability
Solution Approach 1:
The patent leverages existing multi-functional components in modern devices. The image capture device, originally designed for camera functions, is repurposed for authentication by capturing optical patterns. The processor, already capable of handling various computational tasks, is extended to extract and verify authentication data from optical patterns. This approach adds authentication capability without requiring entirely new dedicated hardware.

AI summary
This disclosure describes techniques for device authentication and/or pairing. A display system can comprise a head mountable display, computer memory, and processor(s). In response to receiving a request to authenticate a connection between the display system and a companion device (e.g., controller or other computer device), first data may be determined, the first data based at least partly on biometric data associated with a user. The first data may be sent to an authentication device configured to compare the first data to second data received from the companion device, the second data based at least partly on the biometric data. Based at least partly on a correspondence between the first and second data, the authentication device can send a confirmation to the display system to permit communication between the display system and companion device.
