Virtual Reality (VR) has significantly emerged in recent years in a large variety of fields, from the purpose of developing videogames to that of training, in which nowadays many companies are investing a huge amount of money. With the technology progress, Head-Mounted Displays (HMDs) have been created in order to cover the whole user’s Field of View (FOV) and give him/her a real sense of immersivity in the Virtual Environment (VE). Moreover, several hardware devices have been introduced to allow the user to perceive an increasing degree of immersivity while he/she is operating in VR, like haptic gloves for tactile sensations and force feedback returned by the virtual objects present in the VE.
