Position Node Tracking for Dynamic Sweet Spot Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Hi-Fi audio systems with beamforming loudspeakers lack the ability to accurately track the user's location, requiring trial and error for setting the sweet spot, and necessitate reinstallation when speaker positions change, as the application software cannot effectively monitor the user's position or adjust the sound beam dynamically.
Innovation Solution
A system and method for tracking position nodes using dynamitic vision sensors (DVS) that create temporary nodes for detected moving objects, search for existing nodes, set timers, and manage node pools to ensure accurate tracking and adjustment of the sound beam based on user gestures and movement, allowing for dynamic adjustment of the sweet spot without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If beamforming loudspeakers are used with graphical menu configuration, then users can adjust the sweet spot location, but the system cannot accurately track the user's actual position requiring trial and error
Solution Approach 1:
The patent replaces manual trial-and-error positioning with an optical sensing system. Dynamitic vision sensors detect the user's position through optical signals, automatically determining the sweet spot location without requiring mechanical adjustment or user guessing. The system substitutes optical measurement for mechanical positioning procedures.
Solution Approach 2:
The system performs self-calibration by automatically detecting user position and adjusting the sweet spot configuration without external intervention. The loudspeakers autonomously track user movement and reconfigure beamforming parameters based on detected position, eliminating the need for manual reconfiguration when users move.
2Manufacturing precision
If manual measurement and configuration is performed by technician, then baseline parameter can be set, but reinstallation is required when speaker positions change
Solution Approach 1:
The system transitions from static configuration to dynamic adaptation. Instead of fixed baseline parameters set during installation, the system continuously updates speaker position and sweet spot configuration based on real-time detection. The configuration adapts dynamically when speakers are moved, eliminating reinstallation requirements.
Solution Approach 2:
The system implements continuous feedback loops where dynamitic vision sensors monitor user position and speaker configuration, automatically adjusting parameters to maintain optimal sound quality. This closed-loop feedback enables automatic reconfiguration when physical conditions change, replacing manual measurement and setup procedures.
3Ease of manufacture
If graphical menu mapping is used without environmental information, then initial setup is simplified, but accurate position matching between application and real environment cannot be achieved
Solution Approach 1:
The patent introduces dynamitic vision sensors as an intermediary between the physical environment and the software configuration. These sensors capture environmental position information and translate it into data usable by the beamforming system, bridging the gap between physical space and digital configuration without complicating the user interface.
