Two Cornell University students, glorious by 1 of the pair's receive of Preventive Log Z's Apnea disorder and his struggle to get access to his sleep lab data, distinct to take matters into their own hands, and so they built an EEG machine for their microcontroller lab final project.

Then, being geeks, they decided to use it to play Pong. Because really, who doesn't deprivation to play games with the office of their mind?

In one of their original plans, the pair set resolute detect the color a user was intellection of from a set, after training, supported connected recitation the user's brainwaves. Although they were unable to reach better than 64% truth on the color assortment tests, they were able to reach sufficient accuracy at distinguishing different magnitudes of mu Einstein wave suppression (peculiar of users intelligent most moving, but not moving, their legs) and different magnitudes of alpha brain wave rhythms (symptomatic of users' level of relaxation) that users could reliably control the Pong paddle afterward a bit of practice exploitation either method.

Enough with the technical details: Here's television of the brainwave-controlled Pong in sue:

The device, which uses an old baseball cap arsenic an EEG helmet and an ATmega644 microcontroller to convert the raw, amplified analog betoken from the cap into a digital signaling which is then passed to a computer over a USB serial connection, cost the students to a lesser extent than $75 to material body. They've also posted the source happening Github.
