Solution Overview
Problem
Current methods fail to effectively translate human brainwave data into immersive audio and video experiences that accurately represent an individual's emotional and cognitive states, limiting the ability to create realistic virtual characters in Metaverse environments.
Innovation Solution
A brainwave audio and video encoding system that uses a helmet with a brainwave detector and calculator to process signals from Delta, Theta, Alpha, Beta, and Gamma waves, converting them into music melodies and colors through specific algorithms, allowing for real-time expression of brainwave variations and emotional states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If brainwave signals are converted into music melodies and colors using specific algorithms, then the ability to express brainwave variations and emotional states is improved, but the device complexity increases due to multiple converters and processing units
Solution Approach 1:
The system divides the complex task of brainwave expression into separate functional modules: a melody convertor that transforms brainwave signals into music melodies, a color convertor that transforms them into colors, and a cloud device that stores and processes data. This segmentation allows each component to specialize in one conversion task, improving overall adaptability while making the complex system more manageable and maintainable.
2Reliability
If multiple brainwave parameters are processed and converted in real-time, then the immersion and empathy connection are enhanced, but the computing power and energy consumption increase
Solution Approach 1:
The system performs preliminary actions by pre-processing brainwave signals locally using the attention and meditation calculator and melody/color convertors, then transmits only the essential processed data to the cloud device. This reduces the computational burden during real-time operation, lowering energy consumption while maintaining reliable immersion connection through pre-established processing capabilities.
3Measurement precision
If detailed brainwave data is transmitted to cloud devices for processing, then the accuracy of emotional state representation is improved, but the data transmission time and network dependency increase
Solution Approach 1:
The system merges local processing capabilities (attention and meditation calculator, melody convertor, color convertor) with cloud-based data storage and analysis. This hybrid approach allows detailed brainwave data to be processed locally for immediate emotional state representation while leveraging cloud resources for comprehensive analysis, thereby maintaining high accuracy without excessive transmission delays.

AI summary
A brainwave audio and video encoding and playing system is provided. Based on the research and understanding of the brainwaves, the relations of variations of the brainwaves corresponding to the melodies of the human voice senses and the relations of the human brainwaves to the colors is built so as to create rules for playing of the melodies by musical instrument and colors in a display so that variations of the brainwaves can be expressed by playing of music and display of colors and the messages of brainwaves could be transferred. As a result, the people have the same feeling to the testers.
