AR Microphone Pickup Pattern Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies lack a systematic way to visually represent and control the pick-up patterns of microphones in various environments, making it difficult for users to optimize microphone placement and orientation for effective sound capture.
Innovation Solution
The use of augmented reality to capture images of microphones, determine their location and orientation, and overlay visual representations of their pick-up patterns on a display, allowing users to modify these patterns in real-time through interactive interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual representation of pick-up patterns is implemented, then user understanding of microphone behavior is improved, but device complexity increases
Solution Approach 1:
The patent creates a visual copy or representation of the invisible acoustic pick-up pattern using augmented reality graphics. Instead of directly measuring or displaying the acoustic field, the system generates a graphical model that replicates the pattern's spatial characteristics, allowing users to see what they cannot directly observe without adding complex acoustic measurement hardware
Solution Approach 2:
The patent introduces an intermediary layer between the physical microphone and the user's perception. The augmented reality visual representation acts as a mediator that translates complex acoustic pickup patterns into intuitive graphical displays, bridging the gap between the physical acoustic field and human understanding without requiring direct measurement equipment
2Ease of operation
If real-time visualization is implemented, then user control capability is improved, but processing requirements increase
Solution Approach 1:
The system pre-calculates and stores the relationship between microphone parameters and their corresponding visual representations. When a user adjusts microphone settings, the system retrieves and updates the pre-computed visual model rather than performing complex real-time acoustic simulations, reducing processing demands while maintaining responsive interaction
Solution Approach 2:
The patent implements a dynamic visualization system that updates only the necessary portions of the pick-up pattern display when parameters change. Rather than re-rendering the entire acoustic field continuously, the system dynamically adjusts specific visual elements based on user interactions and microphone state changes, optimizing processing efficiency
Data Source
AI summary
Augmented reality visual display of microphone pick-up patterns are disclosed. An example method includes capturing, via a camera of a computing device, an image of a microphone, and displaying the image on a display of the computing device. The method also includes determining, by the computing device, a location and orientation of the microphone relative to the camera, determining one or more parameters of a pick-up pattern of the microphone, determining a visual representation of the pick-up pattern based on the one or more parameters, and displaying the visual representation of the pick-up pattern overlaid on the image of the microphone.
