MotivationTreatment of phobia
◦Vivo exposure◦VR
Augmented Reality(AR)◦Superimpose virtual elements in real
scene.◦Less costly compares to VR.◦Participants of treatment can see
their own body.
Creation of Immersive PhotographsFor each position
◦Take 180° photograph◦360 ° photograph
= 180 ° photograph + 180 ° transparent white image
Example of Immersive Environment
Virtual
Reality
ExperimentTest the efficacy of immersive
photography to induce sense of presence in user.
41 participants (28 males and 13 females)◦Without acrophobia.
Two environments◦Real◦Immersive photography: AR system
with HMD.
ResultsSUS questionnaire after 7
minutes in an environment.◦Six questions, scores between 1(not
at all) to 7(very much)
ConclusionThis paper presents an AR
system that aims at treating acrophobia.
The SUS results shows that immersive photography provokes a high level of presence in users, although not as optimally as the real world.
