1. An Augmented Reality System for the Treatment of Acrophobia: The sense of presence using immersive photography Juan, M.C., Baños, R., Botella, C., Pérez, D., Alcañiz, M., Monserrat, C. Presenter: D00922019 林敬棋

2. Motivation Treatment 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.

3. Creation of Immersive Photographs For each position ◦ Take 180° photograph ◦ 360 ° photograph = 180 ° photograph + 180 ° transparent white image

4. Example of Immersive Environment Virtual Reality

5. Experiment Test 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.

6. Results SUS questionnaire after 7 minutes in an environment. ◦ Six questions, scores between 1(not at all) to 7(very much)

7. Conclusion This 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.
