Haptic Feedback Generation from Prominent Audio Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to provide high-quality, relevant haptic feedback for media content, particularly in older games lacking detailed haptic signals, leading to muddled and noisy vibrations when using master audio output, which obscures the intended feedback and does not efficiently utilize modern haptic actuators.
Innovation Solution
A system that identifies the most prominent audio component in media content and generates haptic feedback based on it, using a classification unit to determine the relevant sound and a haptics generation unit to create targeted haptic signals, which can be applied in real-time or pre-processed, allowing for improved immersion and accessibility without manual customization of each environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If haptic feedback is generated from master audio output, then haptic feedback can be provided for any media content, but the feedback becomes muddled and noisy obscuring relevant information
Solution Approach 1:
The system segments the master audio output into multiple audio components (dialogue, music, sound effects, ambient noise) and processes each component separately to identify and extract prominent signals, thereby resolving the contradiction between universal compatibility and feedback clarity
Solution Approach 2:
The system extracts the most prominent audio component from the mixed master audio output by analyzing amplitude, frequency, and temporal characteristics, isolating the relevant haptic signal from the muddled mixture to provide clear feedback
2Loss of information
If haptic feedback is generated for every audio component, then comprehensive feedback is provided, but processing cost becomes excessive
Solution Approach 1:
The system extracts only the most prominent audio component from multiple audio sources, discarding less relevant components, thereby providing comprehensive haptic feedback for important events while maintaining high processing efficiency
Solution Approach 2:
The system dynamically changes parameters such as amplitude threshold, frequency range, and temporal window to identify prominent components in real-time, enabling efficient processing by adapting to different media content characteristics without exhaustive analysis
3Manufacturing precision
If manual customization is performed for each media environment, then high quality haptic feedback is achieved, but development complexity increases
Solution Approach 1:
The system automatically analyzes audio components and generates appropriate haptic feedback without requiring manual customization for each media environment, achieving high quality feedback while eliminating complex development efforts through self-configuration
Solution Approach 2:
The system dynamically adjusts haptic parameters based on automatic analysis of audio characteristics, enabling high-quality adaptive haptic feedback across different media content without manual intervention or complex development workflows
