Deep Learning in Brain-Computer Interface

A Brain-Computer Interface (BCI) is a system that extracts and translates the brain activity patterns of a subject (humans or animals) into messages or commands for an interactive application. The brain activity patterns are signals obtained with Electroencephalography (EEG). The concept of controlling devices solely with our minds is nothing new. Science fiction and Hollywood movies have been known to depict this. Several studies and experiments have been conducted, such as monkeys controlling robotic arms to feed itself, controlling a wheelchair and controlling cursors to type about eight words per minute.
