Visual tests for headsets
Visual interfaces in the field of virtual reality

In the case of professional applications where the quality of vision is very important, it is necessary to evaluate the bias induced by the simple wearing of a helmet, even before considering the vision itself. This is the case, for example, in applications where the posture of the user's head is important for the virtual tasks to be performed (e.g., studying the visibility of a road scene from inside a vehicle). To study this and characterize the quality of a visiocasque as a visual interface, we need to do more than simply ask the user: can you see the images? Unless we're content with "flashy" demonstrations.

The use of a video headset is intrusive, in the sense that the headset is more or less heavy, its movements may be more or less constrained by the video cables, the head's center of gravity may be displaced, etc. The use of a video headset is also intrusive,...
