Abstract
"Progress in understanding presence is inhibited by the fact that we are unable to agree what it is we are talking about. What one researcher means by presence is not the same as what another means, and from this stems confusion about how to evaluate models of presence, how to measure it, and how it relates to other psychological phenomena such as mental imagery, attention and emotional engagement. If presence is a phenomenon worthy of investigation, it has at least to be characterised in a way that differentiates it from other phenomena already under long-term investigation (such as those listed above). And this characterisation should lead to ways of measurement that can, in the best case, cleanly discriminate between changes in presence and changes in other phenomena. Over the two decades of increasingly active presence research, several definitions of what characterises presence have been put forward. We suggest that, of these, there is one that meets the needs of future progress in the field: electronically mediated presence is the perceptual illusion of being in an external environment. The key word here is perceptual, not least because of the implications it carries for measurement. We know how to measure the effectiveness of perceptual illusions objectively, and we can expect to be able to distinguish presence defined in this way from other psychological phenomena."
