Moscow-based hacker artist ::vtol::, a.k.a. Dmitry Morozov, is back with another impressive project. His latest, called 2ch, is an interactive, pyramid-shaped instrument that enables two people to communicate via brain activity.

2ch consists of two NeuroSky EEG interfaces worn by both users, as well as two servo motors with a hall sensor and magnet, a two-channel sound system, a couple screens, and an Arduino. In terms of software, the instrument uses Pure Data and Max/MSP.

As Morozov explains:

The project is an instrument for communication between two people by means of visualising the electroencephalograms of two members, which are translated into sound, mechanical motion, and video images. Two participants should try to synchronize their minds, guided by the pitch of the tone, visualisation and movements of mechanical parts.

You can read more about the brain-to-brain interface on Co.Design, and see how it works below!

Clara

Clara is a smart lamp able to respond to your brain waves and subtly adjust your environment. The project, running on Arduino Uno, was created by  Marcelo Mejía Cobo, Belen Tenorio, and Josh Sucher for a class at the School of Visual Arts in NYC (US).

The team worked with the Neurosky MindWave Mobile, a Bluetooth EEG-reading headset in order to wirelessly detect “attention” and map the lamp’s color temperature and speaker volume accordingly:

At first, the lamp emits a warm, comforting glow, conducive to idea generation and creativity. But as you start homing in on a specific idea, the light becomes crisper and cooler, and the volume of the ambient noise flowing from the embedded speaker slowly increases, enhancing your ability to concentrate and block out external distractions.

In the picture below you can see the inside of the lamp with the Arduino Uno and Adafruit Music Maker shield:

[Chip Audette] owns (at least) two gadgets: one of those remote control helium-filled flying shark (an Air Swimmer), and an OpenBCI EEG system that can read brain waves and feed the data to a PC. Given that information, it can hardly surprise you that [Chip] decided to control his flying fish with his brain.

Before you get too excited, you have to (like [Chip]) alter your expectations. While an EEG has a lot of information, your direct thoughts are (probably) not readable. However, certain actions create easily identifiable patterns in the EEG data. In particular, closing your eyes creates a strong 10Hz signal across the back of the head.

To control the fish, [Chip] wired up the stock remote with an Arduino. The problem was that although the remote has five different actions, [Chip] could only easily detect eyes being closed. OpenBCI lets you read different people’s EEGs on different channels, so [Chip] wired up four friends and now it takes five people to completely control the Jaws’ brother.

We’ve talked about OpenBCI before along with a tear down of another EEG device, the Muse headset. We just hope [Chip] is prepared for the obvious “jumping the shark” comments.

Io Flament_2     Time required: A weekend Cost: $100 — $130 Ever wanted to visualize your brain activity? Electroencephalography (EEG) uses electrodes placed against the scalp to detect the tiny electrical changes that occur when neurons fire. By amplifying these signals through a computer, you can observe brain activity in real-time. Using an […]

Build an EEG hat that turns your brainwaves into light!

Ever wanted to visualize your brain activity in real-time? Move an object on a screen with your mind? EEG devices are fantastic fun and allow you to do such things!

This tutorial will show you how to make an illumino: an easy-to-use recreational EEG device hidden inside a comfortable beanie, that turns your brain activity into an array of colorful light. Colors and brightness are manually selectable and adjustable via a small discreet pushbutton switch. The custom Arduino software is accessible via a USB port, allowing you to easily change it as you wish. The hat also works fine without the lights, should you wish to use it only as an EEG device. I recommend using Processing to create beautiful real-time moving graphical visualizations of your brain activity (code included in tutorial).

Visualizing the process of human brain with magnets and liquids

solaris

Solaris is an interactive installation created by Julia Borovaya (idea curation), Edward Rakhmanov (robotic system, chemistry), Vtol (programming, electronics) with the help of Alexander Kaplan, professor of neurophysiology:

it demonstrates the field influence of the permanent magnet on the magnetic and spirit (fluorescent) liquids. Two liquids constitute the diphasic system. Due to liquids movements and their surfaces’ modifications we visualize the unique processes of human brain. The spectator wears on neuro interface Emotive Epoc, the device computes a brain activity and sends information to the installation machinery.

To test the project people of different ages, social groups and professional areas were invited. Test results confirmed that brain activity and mood of the man reflect on the dynamic and character of liquids movements in the sphere. Object reacts on the changes of mind and emotion states. People who spent a plenty of time with the object managed to influence the dynamic and direction of the liquids on the unconsciousness level. We also reveal that the installation visualizes the temperament of the person. The object copies your mental organization and echoes it on the liquid’s surface. The object becomes a part of the participant.

It runs on Arduino Uno controlling dc motors, 2 actuators and a custom digital motor control system interface.

Wombats are fast. Hey, let's go ride bicycles!My Brainwave-Controlled Zen Garden is similar to a standard desktop zen garden in that you rake sand to calm yourself. In my version, though, the rake and resultant patterns are controlled by your actual brainwaves. If you are tense and worrisome, the rake moves randomly and quickly, scribbling odd patterns in the sand.
