Brain Recorder

Electroencephalography (EEG) is the recording of electrical activity along the scalp. Our mind regulates its activities by means of electric waves which are registered in the brain, emitting tiny electrochemical impulses of varied frequencies, which can be registered by an electroencephalogram. These “brainwave” frequencies are split into different bands. There is ongoing research that attempts to correlate the frequencies in the different bands to different emotional states and levels of concentration.

With the increase in availability of commercial EEG devices, such studies can be sped up by making the collection of data easier, faster, and mobile. Creating a mobile application that facilitates the gathering of brainwave data using a commercially available EEG device, can potentially help make brain controlled interfaces feasible. A larger pool of data would be available to help perfect algorithms that would associate certain brainwave patterns with a computer action.
