The paper presents a novel multimodal-based methodology for consciousness study of individuals with unresponsive wakefulness syndrome. Two interfaces were employed in the experiments: eye gaze tracking system – CyberEye developed at the Multimedia Systems Department, and EEG device with electrode placement in the international 10-20 standard. It was a pilot study for checking if it is possible to determine objective methods based on multimodal techniques which could replace or support current expensive and difficult to access neuroimaging techniques, like fMRI, PET, utilizing in evaluation of consciousness state. The multimodal-based methodology consists of several phases of research involving subjects. Hearing examination based on objective methods (OAE, ABR), consciousness test based on analysis of visual activity, examination of visual neural pathway with Steady State Visually Evoked Potentials and EEG-based comprehension test were proposed. The results obtained within conducted experiments and presented in this paper suggest that proposed objective-subjective methodology could potentially be introduced into clinical facilities after further validation.
