Until recently, direct brain-computer communication was a topic known only from science fiction novels and movies. Along with the development of brain imaging technology, the apparatus enabling the recording of brain waves has become many times cheaper and miniaturized, and thus more accessible. We decided to check whether it is possible to prepare software that correctly recognizes the architect’s mental commands and interprets them as program functions.
In the following project, we use a device Emotiv-Epocx, a 16-channel electroencephalograph with a measurement frequency of 256 samples per second. The operation of the device is quite simple. Placed on the head, it measures the electrical voltage at 16 points on the scalp. By comparing signals in different parts of the head, it is able to read brain waves. The device is wireless, lightweight, communicates via Bluetooth and has a battery that allows for continuous operation up to 9 hours.
