Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional audio headsets in virtual reality environments lack depth perception and dynamic sound adjustment, limiting the user's ability to locate sound sources and providing an unrealistic experience due to their two-dimensional perspective and fixed directional sound transfer, which also require high-performance computing resources and are not designed for real-time, lifelike experiences.
Innovation Solution
A computer system with a headset that includes ear cups with drivers for multi-channel audio signals, a microphone for sound wave reception and processing, and a haptic device for providing vibrations, along with a remote handheld device for tactile feedback, all integrated with sound and microphone processing modules to dynamically generate audio and haptic feedback based on virtual reality environment geometry and user movement, enhancing sound direction perception and immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional headsets use two-dimensional perspective or fixed directional transfer of sound waves, then the device complexity is reduced, but the sound realism and depth perception are worsened
Solution Approach 1:
The patent transitions from traditional two-dimensional sound transfer to three-dimensional spatial audio by incorporating multiple drivers (front, rear, top, bottom) that emit sound waves from different directions. This dimensional expansion enables realistic depth perception and localization of sound sources in virtual reality environments, directly resolving the contradiction between device complexity and sound realism.
2Ease of operation
If traditional headsets use fixed directional sound transfer, then the ease of operation is improved, but the adaptability to user movement and virtual environment changes is worsened
Solution Approach 1:
The system dynamically adjusts sound wave emission based on real-time user head movements and avatar positions in the virtual environment. Multiple drivers are activated and deactivated according to the direction the user is facing and the location of sound sources, enabling the audio experience to adapt continuously to user actions while maintaining ease of operation through automatic adjustment.
Solution Approach 2:
The system incorporates microphones that capture user speech and environmental sounds, converting them to audio signals that are processed and re-emitted through the multi-driver system. This feedback loop ensures that the audio output remains synchronized with user actions and virtual environment changes, enhancing adaptability while preserving operational simplicity.
3Measurement precision
If high-performance computing resources are used to achieve required audio capability and quality, then the sound realism is improved, but the accessibility to standard computers and mobile phones is worsened
Solution Approach 1:
The patent replaces computationally intensive audio processing with a hardware-based spatial audio system that uses multiple physical drivers positioned around the user's head. By distributing sound emission across multiple independent drivers rather than relying on complex software rendering, the system achieves realistic audio quality with reduced computational demands, making it accessible to standard computers and mobile phones.
