“…[9,10,12,15,[20][21][22]; and (ii) by using specially designed interaction devices similar to the ones used in the real control, e.g., machine operation consoles or vehicle control cockpits [23]. On the other hand, VR immersive applications are also subdivided into two subcategories, according to the visualization system of the virtual world: (i) the head-mounted display (HMD), which consists of active glasses with a small screen placed properly in front of each eye (Figure 2b) [7,[24][25][26][27]; and (ii) the virtual CAVE (cave automatic virtual environment), where the virtual world is projected on the walls, ceiling, and floor of a room by diverse stereoscopic projectors ( Figure 2). In this last case, the user must wear passive stereo glasses [28,29] Nevertheless, the use of VR in engineering education spreads further than the use of 3D-VLs.…”
