Measuring Brain Signals using Emotiv Devices

BCI (Brain-computer interface) use for scanning the brain activity. This is the interface, which creates the connection between the brain and the computer. Thanks to this interconnection allows us to observe the brain activity. BCI translate brain signals into control commands for external devices using decoding algorithm. BCI systems can be very useful for examining areas neurobiology, neuropsychology, physiotherapy, neurophysiology etc. The aim of this article is to prove that brain-computer interface is a helpful and quite precise tool. To achieve that objective has been created few real-life examples, among which we can find a practical use. The results show that this device is indeed helpful (in a medical field, rehabilitation or psychology). In practice, unfortunately not used very much.
