Application of bio signals in the brain-device interfaces

Abstract

In the paper, a review of the current state of knowledge in the field of brain-machine interfaces based on bio signals, is presented. Different types of bio signals, which can be used to control of devices are shortly characterized. Special attention is given to the use of EEG signals in the most interesting and complex brain-machine interfaces. The EEG device is described and characterized. Initial investigation results made at Poznan University of Technology in the area of application of consumer type EEG devices to brain signal acquisition are presented. The use of artificial neural network for this signal recognition are described and discussed.
