| Summary: | Various researches on brain computer interfaces have been conducted for physical impaired to control an electronic assistive device using only their brainwaves or scientifically known as electroencephalogram (EEG). The problem of current EEG-based brain computer interface (BCI) system is its performance in accuracy and time response. There are two types of BCI; synchronous and asynchronous. Synchronous BCI is a cue based system which is restricted to a predefined time frame whereas an asynchronous BCI is a self paced system which operates independently of a cue stimulus. The main objective of this review study is to conduct a literature review on the effect of asynchronous design to the accuracy and time response of BCI systems. From the scope of EEG signal processing, research papers and conference proceedings had been collected and reviewed from abstract to conclusion. Results from five significant researches has been compiled and compared. The findings obtained in this study will be significant to researchers and engineers pursuing in EEG-based BCI system in biomedical and health science industry. |
