Abstract

Brain-Machine Interfaces(BMI) are interfaces that control machines by decoding brainwaves, which are electrical signals generated from neural activities. Although BMIs can be applied in various fields, their widespread usage is hindered by the low portability of the hardware required for brainwave measurement and decoding. To address this issue, previous research proposed a brain-machine interface system based on the Internet of Things (IoT) using cloud computing. In this study, we developed and tested an application that uses brainwaves to control the Pong game, demonstrating the real-time usability of the system. The results showed that users of the proposed BMI achieved scores comparable to optimal control artificial intelligence in real-time Pong game matches. Thus, this research suggests that IoT-based brain-machine interfaces can be utilized in a variety of real-time applications in everyday life.

뇌-기계 인터페이스(BMI)는 신경활동을 통해 발생하는 전기 신호인 뇌파를 해석하여 기계를 제어하는 인터페이스이다. BMI는 다양한 분야에 적용될 수 있으나 뇌파 측정 및 해석을 위한 하드웨어의 휴대성이 낮아 대중적으로 사용되기에 어렵다는 단점이 있다. 이런 문제점을 해결하기 위해 이전 연구에서는 클라우드 컴퓨팅을 이용한 사물인터넷 기반 뇌-기계 인터페이스 시스템을 제안하였다. 본 연구에서는 위 시스템의 실시간 사용성을 증명하기 위하여 뇌파로 퐁(Pong) 게임을 조종하는 애플리케이션을 개발하여 테스트하였다. 그 결과 제안된 BMI 사용자가 최적 제어 인공지능과의 실시간 퐁 게임 대결에서 대등한 스코어를 보였다. 따라서 본 연구 결과는 사물인터넷 기반 뇌-기계 인터페이스가 일상생활 속 다양항 실시간 애플리케이션으로 활용될 수 있음을 시사한다.
