The aim of doctoral thesis was to design advanced binocular neurologic interface for communication between a human and a machine with the non-invasive method of monitoring neurologic activities in the nape of head. It is defined by the process of features excretion of the Steady state visual evoked potentials (SSVEP) and further classification or symbol detection within the neurologic activity as a response to binocular coded visual stimulation. In the thesis the whole brain computer interface was defined. In the first stage a suitable device for binocular visual stimulation was defined and formed. This was followed by defining of binocular coded symbols on the basis of frequency and phase and the new set of features, which distinguish binocular coded symbol classes and with the suitable further classification successfully recognize individual symbols. A practical experiment proved that this approach enables increase of information transfer rate regarding interfaces, which use symbols only on frequency or phase basis and without binocular approach. We defined also a new user interface for the purpose of visual communication between a human and a machine in three-dimensional space as a new form of modality within multimodal communication interfaces.
