Notes
Argues that authenticity is key to presence – VEs do not emulate real worlds (too many missing sensory cues) so VE design should leverage user expectation and task context and prioritize relevant sensory channels and cues (higher authenticity). Seeks to establish a framework to reliably predict presence by probabilistically evaluating the VE's authenticity using the tools of Bayesian inference.

Quotes
p.322   "While the perception of a virtual environment (VE) is usually described in terms of its level of immersion and users’ sense of presence, the construct of authenticity might be more useful. The authenticity of a VE depends on whether the affordances and simulations chosen in its implementation support (1) users’ expectations based on their Bayesian priors for regularities in the real world and (2) the users’ intentions in the VE . . . the term ‘‘authenticity’’ refers to whether the virtual environment provides the experience expected by the user, both consciously and unconsciously."   Added by: Mark Grimshaw

"A VE with higher immersion, so the argument goes, should lead to higher fidelity, and generate a greater sense of presence, the subjective experience felt by the user. But if I put you in a highly immersive environment and give you badly designed content to experience, will you perceive the VE as realistic and experience presence? Probably not. What’s missing from this dichotomy of immersion (objective, system-focused) and presence (subjective, user-focused) is a computational theory about the extent to which the VE reflects the expected regularities of world that it is attempting to represent—its authenticity."

"Authenticity’s second stream of thought comes from art historians and archaeologists who think carefully about the past, and who often seek to establish whether artifacts found in the present are authentic. While establishing an artifact’s date and place of origin might be a matter of objective fact, Lovata (2007) argues that these facts are simply nominal authenticity, and that a richer, more complex sense of authenticity is context dependent, and depends on the motivations of the observer."

"I suggest that immersion is the system-based factor that influences presence, and that authenticity is the human-based factor that influences presence"
