| 英文摘要 |
| We propose an algorithm including data preprocessing, feature extraction, and classification. In designing the remote controller with communication function, we develop an electroencephalograph-based (EEG-based) brain-computer interface (BCI) for the asynchronous system of the television remote control. The system can help the patients suffering from Amyotrophic Lateral Sclerosis (ALS) to turn on, turn off, select TV channels and adjust volume using their brain waves. Five healthy subjects took part in train experiments and online experiments；the results demonstrate that the averaged information transfer rate of the system is approximately 35 bits/min and all the subjects can control the system efficiently with an average accuracy of 87% after a special training of procedure. |
