뇌-기계 인터페이스 기술 동향 = Review of Brain-Machine Interface Technology

다국어 초록 (Multilingual Abstract)

The brain-machine interface (BMI) is a new frontier technology developed recently and can be applied to manipulate a machine, robot, computer, etc. by detecting brain waves or activated brain images that arise from the blood oxygen level dependence (BOLD) effect, and are created by a thought. The state of the art in BMI research is reviewed, the R\&D results and the patents for BMIs obtained in major countries, including the United States, the European Union, Japan, and Korea, are presented, and the technological levels of BMIs are evaluated, providing future outlooks for progress in BMIs. In this paper, a BMI using an electroencephalograph (EEG), a BMI using the functional magnetic resonance imaging (fMRI) BOLD effect and a BMI using a brain chip implanted in the brain are reviewed.

인간의 생각에 의한 뇌의 변화(뇌파 또는 뇌신경의 활성화)를 감지하여 기계, 로봇, 컴퓨터 등을 제어하는 뇌-기계 인터페이스(Brain-Machine Interface, BMI) 기술의 국내외 연구개발 동향, 학술정보 및 기술특허 현황 등을 분석하여 미국, 유럽, 일본, 한국 등 주요국의 BMI 기술수준을 평가하고, BMI 기술의 당면과제와 발전방향을 제시하였다. 뇌파계를 이용한 BMI, fMRI BOLD 신호를 이용한 BMI, 뇌에 직접 전극을 설치하는 방법에 의한 BMI 등을 기술하였으며, 앞으로 5~10년 후 BMI 기술의 전망과 실현가능성을 진단하였다.
