Approaching Delta is a superficial telepathy device - it is a new form of communication that skips the barrier of creating and receiving words, symbols and ideas and instead converts brainwaves in one person into brainwaves in another person. Specifically, it is an an electroencephalogram (EEG) connected to headphones via an Arduino Microprocessor. The EEG worn by one person (the transmitter) reads their brainwaves. The brainwave data is fed into the Arduino and converted into a specific type of sound, an auditory illusion, called a binaural beat, which is listened to by another person (the receiver). When one person wears the EEG and the other wears the headphones it subtly alters the listeners brainwaves, and creates a superficial form of telepathy. https://www.youtube.com/watch?v=ZUub0nCbzvI

Approaching Delta is a superficial telepathy device - it is a new form of communication that skips the barrier of creating and receiving words, symbols and ideas and instead converts brainwaves in one person into brainwaves in another person.

The brainwave data is fed into the Arduino and converted into a specific type of sound, an auditory illusion, called a binaural beat, which is listened to by another person (the receiver). When one person wears the EEG and the other wears the headphones it subtly alters the listeners brainwaves, and creates a superficial form of telepathy. By playing one frequency in one ear and a different frequency in the other ear the listener perceives the overlap of the two frequencies, not the two separate frequencies. However, because the sine waves are played through headphones (as opposed to speakers) that sound of the overlapping frequencies only exists in the mind of the listener, not in the physical world - this is the illusion. By setting the gap between the sine wave frequencies to one in the brainwave range the brain is compelled to produce more of that frequency. For example, playing 200 hz in one ear and 210hz in the other produces a 10hz binaural beat, which is in the Alpha brainwave range.

Approaching Delta was made with a consumer grade EEG, a bluetooth receiving module, an Arduino microprocessor, Ableton Live audio production software, Max MSP, and a pair of headphones. The primary code for converting the brainwave data into mappable signals was written in the arduino programming language, piped through Max MSP into Ableton, where it was converted into sine waves. The secondary code for visualizing the brainwave data was written in the processing programming language
