Personalized Audio Delivery via Triangulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surround sound systems fail to deliver personalized audio experiences to multiple listeners located at different positions, as they do not effectively account for individual listener positions and preferences, leading to suboptimal audio localization and quality.
Innovation Solution
A system comprising a media device with a processor and memory, connected to multiple speakers, uses a position module and audio profiles to deliver personalized audio by determining user device positions through calibration signals and triangulation, and applying customizable audio settings such as language and listening modes based on user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional surround sound systems are used, then audio channels are separated and played through speakers at different locations, but the system fails to deliver personalized audio experiences to multiple listeners at different positions
Solution Approach 1:
The system performs preliminary calibration by determining the positions of multiple listeners and their audio preferences before actual audio playback. Audio profiles are pre-configured for each listener based on their location and preferences, enabling personalized audio delivery without real-time computation during playback
Solution Approach 2:
The audio system is segmented into multiple independent audio profiles, each tailored to a specific listener's position and preferences. The overall audio signal is divided into separate channels that are independently processed and delivered to different speakers based on individual listener requirements
2Measurement precision
If audio profiles are created for each listener position, then personalized audio experience is improved, but the process of determining user device positions and applying audio settings increases system complexity
Solution Approach 1:
User devices perform self-service by determining their own positions through calibration signals. Each device receives calibration signals from speakers, calculates its position and orientation autonomously, and communicates this information back to the media device, eliminating the need for complex external tracking systems
Solution Approach 2:
The system implements feedback mechanisms where user devices report their determined positions and audio preferences back to the media device. This feedback loop enables the system to continuously optimize audio delivery based on actual listener positions and preferences
