What Are Brain-Computer Interfaces and the EPOC Neuroheadset?
If you’ve read Think Artificial before, you’re probably somewhat familiar with BCIs. Brain-computer interfaces. Devices that allow us to control machines using only our minds. The key technology is called electroencephalography (EEG). A device monitors your brain’s electrical activity via sensors on your scalp. It’s been used for medical purposes for years — and the futuristic image on the side here depicts setup for a musical brainwave performance at the Deconism Gallery in 2003, for example. The audience of a concert hooked up to the EEG devices to affect music and lighting. However, monitoring the waves is different from detecting their patterns and using them reliable “triggers”, like Emotiv Systems’ EPOC device and software does. For this to work, two things are essentially required: The user has to practice producing a repeating, recognizable pattern. But there’s always noise (because it takes practice to be able to visualize the same image, or sequence), so the second thing is t
