In this article, we present an initial study of phantom sensation synthesis on the back side of the head. We proposed to render a vibrotactile flow between the temple, occipital, and parietal regions on the head using four actuators. Taking into account that humans perceive a vibrotactile stimulation on selected locations differently loud, we normalized a perceived amplitude of respective actuators through psychophysical experiment. By pairwise actuating of adjoined actuators, we rendered ten patterns of vibrotactile flow in different directions and evaluated through additional psychophysical experiment. The results shown 86 percent of the identification accuracy where the user felt continuous vibrotactile flow between active actuators.
