The NeuroSky MindWave™ is a device for monitoring electrical signals generated by neural activity in the brain. The device is worn on the head and consists of a headband, an ear-clip, and a sensor arm containing the EEG electrode which rests on the forehead above the eye (FP1 position). Compared to traditional EEG devices, it is inexpensive, simple to operate, and unobtrusive. The aim of the study was to investigate how well the headset performed with regards to the quality and quantity of data it gathered in order to determine whether it could be more widely used as a cost-effective means of recording EEG output in a human factors research setting. This was achieved by instructing a sample of 24 participants to undertake six cognitive tasks whilst the output from the NeuroSky MindWave™ was recorded.
Overall, our data produced mixed results. Only the Relaxation measure produced changes in brain wave power which were consistent with our expectations (when participant’s relaxed their meditation power increased). All other tests were either non-significant or produced results which contradicted our expectation. Possible explanations for the observed results are expounded.
From the data gathered the usefulness of the MindWave device in a human factors research setting appears to be limited. However, the authors acknowledge that changes to the procedure and data processing might significantly improve the quality of the data gathered.
