Spectral Forms

tumblr_inline_nleqv0IQzN1r1ofietumblr_inline_nleshmU6T21r1ofieOver the past few months, we have been working with brain waves. What started at Artek Circle hackathon last year has grown to be Spectral Forms. We have taken consumer-grade EEG wearables, and tried to see what is the potential and limits of these devices are. Available online and for only $50, it has opened up a whole new area to play with. These small devices claim to accurately detect and interpret the tiny electrical impulses our brains output. These impulses can be broadly categorised into four bands, representing four different ‘levels’ of thought.

We have created software programmes that takes in the brain data, then displays it in a number of different patterns. We also play back an audio representation back to the wearer via a bone conduction unit. You can hear a sample below.

 

Lab in the Gallery

We are now taking the project to the public to try out. From the 24th till the 29 March we will be in the Science Gallery as the Lab in the Gallery . We are hopping that people will drop into us and listen to their own thoughts for a while. During our time there, we hope to work more on the 3D printing of brain wave data and testing the accuracy of the sensors.

 Skull Radio Workshop

We are running our Skull Radio Workshop during our time in the Science Gallery where you get to make your very own bone conduction kit. For more information on the workshop and tickets visit here.

Spectral Forms forms was created by Sinead McDonald, Jeffrey Roe and Krzysztof Foltman with lots of help from TOG members.
