| contents | How we experience immersive virtual environments: the concept of presence and its measurement Mel Slater Beau Lotto Maria Marta Arnold Maria V. Sanchez-Vives Psicología Presence immersive virtual environments This paper reviews the concept of presence in immersive virtual environments, the sense of being there signalled by people acting and responding realistically to virtual situations and events. We argue that presence is a unique phenomenon that must be distinguished from the degree of engagement, involvement in the portrayed environment. We argue that there are three necessary conditions for presence: the (a) consistent low latency sensorimotorloop between sensory data and proprioception; (b) statistical plausibility: images must be statistically plausible in relation to the probability distribution of images over natural scenes. A constraint on this plausibility is the level of immersion; (c) behaviour-response correlations: Presence may be enhanced and maintained over time by appropriate correlations between the state and behaviour of participants and responses within the environment, correlations that show appropriate responses to the activity of the participants. We conclude with a discussion of methods for assessing whether presence occurs, and in particular recommend the approach of comparison with ground truth and give some examples of this. 2009 artículo científico 0066-5126 https://www.redalyc.org/articulo.oa?id=97017660004 en http://www.redalyc.org/revista.oa?id=970 Anuario de Psicología application/pdf Universitat de Barcelona Anuario de Psicología (España) Num.2 Vol.40 |
