Surround Sound Warning System Using Spatial Audio for Directional Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio warning systems in vehicles often divert the driver's attention from the road, reducing reaction times due to the need to interpret visual warning lights, which can be distracting.
Innovation Solution
A surround sound based warning system that uses sensor fusion, computer vision, and spatial audio to detect events and provide directional audio warnings, allowing drivers to focus on the road while receiving alerts about potential hazards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual warning lights are used to indicate events, then the driver can identify the location of events, but the driver's attention is distracted from the road
Solution Approach 1:
The patent replaces the visual warning light system with an acoustic warning system that uses spatial audio to convey event location information. The acoustic warning generator creates directional sound waves that indicate the location of detected events, allowing drivers to receive location information through hearing rather than sight, thus maintaining attention on the road while still obtaining necessary information.
2Loss of time
If audio warning signals are used, then the driver's attention can remain on the road, but the location information may be less clear than visual indicators
Solution Approach 1:
The patent applies local quality by creating directional acoustic warnings that provide location-specific information. The acoustic warning generator produces sound waves with specific spatial characteristics that correspond to the location of detected events, allowing the driver to perceive not just that an event occurred but also its precise direction and relative position through the spatial properties of the sound.
Solution Approach 2:
The patent uses spatial audio as an intermediary to convey location information. Instead of directly displaying visual information or providing vague audio cues, the system transforms event location data into spatially-encoded acoustic signals that the driver can interpret directionally, serving as an effective mediator between the detection system and the driver's perception.
Data Source
AI summary
An apparatus includes an interface and a processor. The interface may be configured to receive data readings generated by a plurality of sensors. The processor may be configured to perform a fusion operation on the data readings to detect an event, determine a location of the event with respect to a vehicle based on the data readings, convert the location to spatial audio data and generate an audio warning signal based on the spatial audio data. The sensors may generate video data as one of the data readings. The processor may perform video analysis on the video data to calculate measurements using a number of pixels to the event to calculate the location. The spatial audio data may be in a format compatible with a surround sound speaker system of the vehicle. The audio warning signal may indicate the location of the event using the surround sound speaker system.
