Microphone-Speaker Position Mapping for Device Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios where multiple users wear neck-hanging-type microphone-speaker devices, it is difficult to ascertain which device a user is wearing and its settings due to similar device numbers displayed on a control device, complicating coordination during meetings.
Innovation Solution
A voice processing system that includes an estimation processing unit to determine the position of each microphone-speaker device relative to a communication device and a display processing unit to show the device's position on a display, allowing users to easily identify and set settings for each device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple microphone-speaker devices are used simultaneously in the same area, then the system can support more users, but it becomes difficult to identify and manage individual devices due to similar device numbers
Solution Approach 1:
The patent introduces spatial positioning information as a new dimension to distinguish between devices. Instead of relying solely on device numbers, the system displays the physical location of each microphone-speaker device on a map or floor plan, enabling users to identify their devices through spatial context rather than ambiguous numerical identifiers.
2Loss of information
If device numbers are displayed on the control device, then identification information is provided, but users cannot easily ascertain which device they are wearing among multiple similar devices
Solution Approach 1:
The control device serves as an intermediary that receives positioning data from multiple microphone-speaker devices and presents this information in a user-friendly spatial format. The control device translates raw device coordinates into visual representations on a map interface, mediating between the physical device locations and the user's need to identify their specific device.
3Ease of operation
If spatial positioning is implemented, then device identification is improved, but data transmission and processing requirements increase
Solution Approach 1:
The positioning system leverages existing communication infrastructure between microphone-speaker devices and the control device. The same data transmission channels used for voice communication are also utilized for exchanging positioning information, eliminating the need for separate dedicated positioning hardware and reducing overall system complexity.
