horizontally. Even though various types of devices are available on the market, which
will be presented in the paragraphs to come, we would like to convince you that it is
always possible to design a specific device that answers the problemof visual immersion
required by the application (as per the sensorimotor and cognitive I 2 ) more precisely.
Instead of using a “ready-to-wear'' (or even better, a “ready-to-see''), one should rather
opt for a “custom-made'' device. That is precisely what we have tried in the IHS10
project (project of the Systematic pole). The objective of this project is to help the
car manufacturers and car equipment manufacturers to review the project and modify
the design of the vehicle's interior, especially the dashboard. To show a dashboard in
relief, we have used a sufficiently large screen to represent a life-sized dashboard. The
screen is very close to the observer: A part of the screen needs to be cut to put the legs
below the dashboard. The observer can then see the 3D images without stress and with
correct perspectives (orthostereoscopic vision). His head is tracked so that he can see
the dashboard from different angles in real time (Moreau & Fuchs, 2001).
To sum up, before choosing or designing a visual interface, it is necessary to
determine the visual acuity, field of vision, perception of depth (stereoscopic vision,
with or without head tracking, or monoscopic vision), immersion of the eyes (head-
mounted display - visiocube or not) and the frequency of display required for the
application depending on the sensorimotor and cognitive I 2 .
Visiorooms or immersive rooms
There are two main types of configurations for visiorooms: on a large flat screen (like
Barco's CADWall, see figure 11.11) or a semi-cylindrical screen (like SGI's Reality Cen-
ter, see figure 11.12). In case of a semi-cylindrical screen, the field of vision covered for
the observer at the centre is in general 160 to 180 . These configurations are generally
