Over 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.
