New Device Uses Brainwaves To Create Light Displays

Gadgets |

It’s hard to believe that these lights are being completely controlled by what’s going on in the user’s head. From the different colors and patterns, everything the rig is doing is directly correlated with how that person’s brain is functioning. To understand how this works, it’s important to learn about the science behind it.

Electroencephalography, or EEG, is an electrophysiological monitoring method to record electrical activity of the brain. While it has largely been used for scientific research, the University of Nottingham, in an effort to demonstrate how what is arguably the most important organ in the body works, has recently figured out how to take the readings and turn them into light displays.

They developed a special headset that is connected to the lights, which are shaped like a human brain, in order to reflect the actual activity happening in the user's head. The device sends signals to the rig, where certain brain frequencies create the pattern in the display.

Different projections can come from having your eyes open or closed. When open, the lights turn blue due to fact that more is happening when the brain is processing all of the data that the eyes are receiving and sending its way. When closed, the rig displays red because brain activity lessens as a result of having less visual information to compute.

And the team at the university is not stopping there. They’re also working on a new Magnetoencephalography, or MEG, scanner that presents an alternative to a traditional MRI machine. Instead of needing the patient to be completely still for an extended period of time, the new device gives users the freedom of mobility. Hopefully in the future both of these impressive developments will be more accessible to everyone...
