Using a cyberlink mental interface for relaxation and controlling a robot

摘要

This paper discusses a brain computer interface technology that allows disabled persons with physical and/or mental disabilities to control a computer to play games and communicate at a basic level. It was interesting that a head administrator at the institution where the research took place noted that it was her opinion that the people who took part in the research seemed more relaxed, a little more self confident, and many appeared to really reduce their involuntary movements during game playing. The researcher asked a group of people to relax at the beginning and end of each test session over a period of approximately a year. A data capture program using a FFT (fast fourier transform) averaged the amplitude of EMG (Electromyograph) signal waves over five seconds to measure relaxation. The data was tabulated by and the results are displayed. The Cyberlink target audience was found to be intelligent persons with no other method of operating input devices or controlling their environment. It was discovered during formal interviews and during experiments that quadriplegic persons wished to use the Cyberlink not only for communication and recreation but to also power a robotic arm much as one uses a prosthetic arm.
