Brain-computer interfaces have their origins in Hans Berger's seminal work in electrophysiology on brain waves in 1920. However, it was not until the 1960s that direct communication between a brain and a computer was demonstrated. Edmond Dewan trained volunteers to control certain brainwaves in order to manage a light or send Morse code messages by "thinking" (Dewan 1967). If the power of these brainwaves, measured by an electroencephalograph (EEG), increases or decreases, then the computer understands that the subject wishes to turn the light switch on or off or to generate or not generate a Morse code pulse. A year later, he collaborated with the artist Alvin Lucier, who created a musical performance by making live percussion sounds through his brain activity. At the same time, Joseph Kamiya pioneered neurofeedback, demonstrating that it was possible to regulate one's own brain activity with visual, auditory or tactile stimuli and, in turn, improve cognitive performance. In 1973, Jacques Vidal introduced the term brain computer interface (BCI), which remains to designate all types of direct communication between a machine and a user, passing only through brain activity, the latter being measured and analyzed by the system.
