MUSE headband controler

MUSE is a flexible, adjustable, lightweight headband with 4 sensors - including two on the forehead and two behind the ears. It communicates over Bluetooth and is compatible with iPhone, iPad, Android, Mac OS, Windows and Linux. This is a new competitor to Emotiv or NeuroSky companies.

The Canadian startup InteraXon says that it's specially designed to work with a family of applications with exercises for brain health, fitness training, stress management, studying and many more. MUSE is expected to launch in 2013 and retail for around $200. 

Main features:
  • Open communication standard to allow people to write their own device drivers;
  • Rechargeable battery that lasts for 10 hours of use;
  • The headband produces bipolar readings using AFz as the reference for AF3, AF4, TP9, TP10;  
  • The 4-electrode montage enables estimation of hemispheric asymmetries;
  • EEG signals are oversampled and bandpass filtered for noise reduction then downsampled to yield a selectable output sampling rate from 100 Hz to 600 Hz with 2uV (RMS) noise;
  • Active noise suppression is achieved with a DRL - REF feedback configuration using centrally positioned frontal electrodes. 

In my opinion, using an equipment that reads EEG in real-time, when you are running or walking, will have a lots of "noise". I am very curious to see if InteraXon is able to overcome this big challenge.
