Many
authors maintain in their work that the presence feeling in the
virtual universe only survives if the player is unaware of the
technical interference. The technical system is a mediation between
the subject body and the virtual environment. There are many ways
to theorise this mediation and therefore many types of explanations
given to explain the fact that the user is no longer aware of
the technical system. The more common is the "immersion theory".
This is a technical theory. We propose a more psychological theory
based on activity theories. We think that the transparency of
the mediation appears with the subject practise and the increase
of it.
We propose a new methodology to assess the feeling of presence
to show that this feeling varies during the activity.
We don't find that the more a subject is experienced the more
he feels present. We discuss this result and conclude that there's
a complex relation between the feeling pf presence and the transparency
of the mediation.
We find that the feeling of presence varies according to the activity.
This second result can't be explained by the theory of immersion.
This result support our proposition but we need more results to
conclude.
