ABSTRACT
The objective of a VR headset is to provide a stereoscopic vision using two small screens, a large field of view corresponding to the visual field of the user and an immersion of the eyes. There is no ideal and universal visual interface but the main objective of a VR headset is to be a visual interface which must possess metrological characteristics that correspond to the maximum capacities of the human visual system. We, however, have a very long way to go to reach this goal. This visual interface should thus offer four additional capacities over an ordinary screen:
– large horizontal and vertical fields of vision corresponding to those of our eyes; – stereoscopic vision in the entire binocular field of vision; – high graphic resolution using all the performances of monoscopic and stereoscopic
acuities; – and a gaze immersion in the virtual world. Achieving this is possible only if
the visual interface is a VR headset which is connected to a sensor locating the orientation of the operator’s head (see section 5.5).
