REAL WORLD
Figure 2.2 Anthropocentric diagram of the perception of real world by man
All the sensory stimuli together give a coherent perception of the world. We must
not understand the perception as a passive phenomenon, which is the traditional inter-
pretation of the processing of sensory data. Human perception is active and this must
not be forgotten while understanding a subject immersed and interacting in a virtual
environment. We can present, in a simple manner, human behaviour in the real world
from an anthropocentric point of view (Figure 2.2), which we will use in a virtual
world as well.
We will explain in detail the concepts of behavioural interfacing, immersion and
interaction in interactive virtual environments to deduce a model of man interfacing
with these environments. We can use this model as a reference for designing and
assessing any virtual reality application.
2.2 BEHAVIOURAL INTERFACES
2.2.1 Hardware design
For years (Fuchs, 1996), we have been using the term behavioural interfaces rather than
using hardware interfaces or man-machine interfaces (MMI) to correctly differentiate
