Using a brain-computer interface

Dr Mahnaz Arvaneh is developing a brain-computer interface (BCI) which uses electroencephalography (EEG) technology to read brain signals and convert them into actions on a computer screen.

In this video, Mahnaz demonstrates her system, using the Emotiv EPOC+, an EEG headset which measures brain signals.


What challenges do you think we could face when working with mind-controlled systems like this? Why might it be difficult?
