| Summary: | 碩士 === 國立高雄第一科技大學 === 系統資訊與控制研究所 === 101 === Eyes are the window of the soul which use for receive the external messages. However, some kinds of patients that eyes can rotate but the limbs are paralyzed calling Spinocerebellar Ataxia(SCA). On the other hand, the Amyotrophic Lateral Sclerosis (ALS) can receive the external information through hearing and sight sensorial channels but can’t reply to doctor or family by talking or body language. So we try to design easy operation and have high compatibility devices for communication.
The purpose of this study is control the mechanism of eye movement commands with a single channel EEG headset. It can catch the eye movement signals through the single channel wireless EEG headset, then analyze and translate to multi-commands by the programming language. The commands of detecting by the eye movements with up, down, right, left, and voluntary winks based on approaches such as the set threshold algorithms, four-quadrant characteristics algorithms and eight-quadrant characteristics algorithms. Finally, the Chinese text-messaging based on Braille input via Brain-Computer Interface(BCI) are shown and pronounced out in the android phones.
