| Abstract- Immersive and participative environments Immersive 
        and participative environments in this text are spaces which use computing 
        systems to promote a state of perceptive illusion and which incite the 
        visitor to participation stimulating and impressing sensory perception 
        through multimedia resources. In Erkki Huhtamo's (HUHTAMO 1995) examples 
        of different immersion technologies that alter the mind, causing illusion, 
        it is possible to distinguish technologies that induce to these perceptive 
        states as internalized and externalized immersive experiences. Chemical 
        drugs and religious rituals clearly induce to internalized experiences, 
        while television, the cinema, virtual games and computing systems that 
        create media scenarios, like immersive environments which can be acoustic 
        or visual, offer the possibility of experiencing immersion collectively, 
        in groups, as externalized experiences. |
