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.
