This thesis project began with an experiment conducted at the 3DLab of Politecnico di Torino. Sixty volunteer participants engaged in various tasks within three specially designed Virtual Reality environments. The primary objective was to analyze skin conductance (SC), photoplethysmogram (PPG), and electroencephalography (EEG) data. Hemianopia is a loss of vision or blindness in half the visual field, usually on one side of the vertical midline. The most common cause of this damage are stroke, brain tumor and trauma. The experiment involved three distinct Virtual Reality environments: a small market, a house, and a driving simulation. In each environment, various tasks to complete in a predetermined order were assigned to patients.
