Environment Control System Using Correlation Dimension of Alpha Wave

Electroencephalograph has been used in some Environment Control System to help severe disabled people to improve their quality of life. This paper studied the difference of correlation dimension of alpha wave between eye opening and eye closure and proposed a method to control device on and off using correlation dimension of alpha wave. By modifying Grassberger and Procaccia method, the correlation dimension could be achieved automatically. The experiment showed that correlation dimension of alpha wave could be used to distinguish eye opening and closure and help severe disabled people.
