Mind Solutions Inc (VOIS)

There is little comparison. Better to compare the Neurosky products to emotiv's, as both have been on the market for several years.

Here's a comparison chart that covers consumer BCI devices. It stands to reason that multi sensor devices are capable of more functionality than single sensor ones like the Mind Wave and Neurosync.

IMO, the fact that VOIS, at this time, has no app's of their own, will handicap its efforts at garnering sales and recognition.
