Wireless Peripheral Pairing Using Audio Challenge Remapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In crowded environments like aircraft, pairing wireless peripherals such as headsets with networked devices is complex due to similar peripheral names and MAC addresses, leading to increased cross-pairing errors, and existing solutions fail to address this issue effectively.
Innovation Solution
A method involving network abstraction and a challenge system that uses audio challenges displayed on networked devices to match wireless peripherals, allowing software algorithms to determine correct pairings without relying on peripheral identifications, and remapping audio transmissions based on user inputs to ensure correct audio delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pairing methods using peripheral names and MAC addresses are used, then pairing can be established, but cross-pairing errors increase in crowded environments
Solution Approach 1:
The patent introduces an intermediary verification mechanism using audio challenges and visual codes. Instead of directly pairing based on peripheral identifiers, the system mediates the pairing process by displaying unique visual codes on the networked device screen and requiring verification through audio challenges, ensuring that the correct peripheral is paired with the correct device even in crowded environments with multiple similar devices.
Solution Approach 2:
The patent replaces the traditional mechanical/manual pairing method (selecting from lists of peripheral names and MAC addresses) with an automated visual-audio verification system. The networked device displays a unique visual code on its screen, and the peripheral captures this code via camera, substituting the manual selection process with automated code recognition and verification through audio challenges.
2Ease of operation
If users manually select peripherals from lists, then pairing can be made, but user interaction complexity increases
Solution Approach 1:
The patent implements self-service pairing where the system automatically completes the pairing process without requiring user intervention in selecting peripherals. The peripheral automatically captures the visual code displayed on the networked device screen, and the system automatically verifies the pairing through audio challenges, eliminating the need for users to manually navigate through lists or make selections.
Solution Approach 2:
The patent extracts the complex selection process from the user's task. Instead of requiring users to interact with lists of peripheral names and MAC addresses, the system extracts this information and presents it in a simplified visual code format on the screen, which the peripheral automatically captures and processes, removing the complexity from the user's workflow.
3Reliability
If audio challenges are used for verification, then correct pairing is ensured, but pairing time increases
Solution Approach 1:
The patent performs preliminary actions by displaying the unique visual code on the networked device screen before the pairing is finalized. The peripheral captures this code in advance, and the system prepares the verification process by presenting audio challenges beforehand, so that when pairing is confirmed, the process is already nearly complete, reducing the perceived time delay.
Solution Approach 2:
The patent uses periodic audio challenges as verification steps during the pairing process. Instead of a single lengthy verification step, the system presents multiple short audio challenges in sequence, allowing the pairing process to proceed in manageable intervals that feel faster and more interactive to the user while still ensuring accurate verification.

AI summary
Systems and methods are described herein for pairing wireless peripherals with networked devices. Knowledge of the location of the networked devices can be used to properly route or transmit audio to paired wireless peripherals, regardless of whether the wireless peripherals are paired with the correct networked devices provided they are networked with other potential devices. This can be accomplished by prompting users to select an input based on an audio challenge to determine which of the wireless peripherals should be mapped to which of the networked hosts.
