Towards a model for a virtual reality experience:: The virtual subjectiveness

After analyzing how VR experiences are modeled within human computer interaction (CHI) we have found there is a deep theoretical gap: Similarly to how the scientific community has defined CHI models for multimedia applications, it would be very important to have such models for VR - obviously the standpoint cannot be the same because multimedia and VIR applications differ in essence. Indeed, there is no formal model to unify the way in which scientists and designers of VR applications define their experiences. More specifically, apart from the isolated initial scheme defined by S.R. Ellis (Ellis, 199 1, Computing Systems in Engineering, 2 (4) 32 1 347; Ellis, 1993, Pictorial Communication in Virtual and Real Environment, 3-11), and a low level model defined by Latta and Oberg (Latta & Oberg, 1994, IEEE Computer Graphics & Applications, 14, 23-29), there is no-model to fully describe the relationship with which the user will be experiencing the VR application.
