ABSTRACT
While the first VR headsets appeared at the end of the 1960s, their industrial usage does not really begin before the 1990s. In fact the first VR headset, developed by Ivan Sutherland (Sutherland, 1968) used only wireframe images, insufficient for an acceptable immersive industrial experience. Real time computer generated images (CGI) with usable quality, i.e. with textured and anti-aliased images, only become accessible at the end of the 1980s with the Silicon Graphics workstations (Kemeny, 1987). PCs with nVidia graphics cards finally bring affordable real time image generation to the general public at the end of the 1990s, consequently leading to the development of industrial VR headsets, although their deployment remains confined to large industrial groups as their prices have remained high until recently.
