“…A simulation can persuade people to change their attitudes or behaviors by enabling them to observe immediately the link between cause and effect (Fogg, 2003). VEs can vividly simulate the consequences of events and actions on users, and are increasingly employed for persuasion in domains that involve risk such as: health, e.g., encouraging people to exercise (Fox and Bailenson, 2009); safety, e.g., perception of fire risks (Chittaro and Zangrando, 2010); sustainability, e.g., attitudes towards climate change (Meijnders et al, 2006). These persuasive applications provide users with virtual experiences of risk such as floods (Zaalberg and Midden, 2010), fires (Chittaro and Zangrando, 2010), aircraft accidents (Chittaro, 2012) or weight gain (Fox and Bailenson, 2009).…”

Anxiety induction and elicitation of associated physiological arousal with Virtual Environments (VEs) is important in diverse domains. This paper evaluates three general anxiety induction techniques. The first augments the VE with a health bar that is often displayed in video games to indicate when the user's avatar gets hurt. The second augments the VE with aversive audiovisual stimuli which are employed in first-person shooter games when the user's avatar gets hurt and include preset heartbeat sound. The third introduces in the previous technique a biofeedback mechanism to control heartbeat sound. The results we obtained on a VE that reproduces a fire evacuation indicate that the third technique produces much higher physiological arousal than the other two, and measures of users' state anxiety are consistent with physiological results. We discuss possible reasons that could explain why the exploitation of auditory heartbeat biofeedback contributes to make the third technique more effective, by linking our study to research and theories of affect and emotions.

“…With more knowledge and awareness of what the event may feel like, people may respond to victims more quickly, enabling more efficient disaster management. Presence, or the degree to which users actually feel they are in the environment, is an important consideration in response; the vividness and intensity of the virtual experience are both factors in promoting attitude change (Meijnders, Midden, & McCalley, 2006).…”
