1. Researchers Use Google Glass In Public, And You Won’t Believe How People React Tamara Denning, Zakariya Dehlawi, and Tadayoshi Kohno

2. In Situ with Bystanders of Augmented Reality Glasses: Perspectives on Recording and Privacy-Mediating Technologies Tamara Denning, Zakariya Dehlawi, and Tadayoshi Kohno

3. BACKGROUND

4. Augmented Reality Devices Augmented Reality: Vision ‒Sensing ‒Real-Time Context ‒Information Overlay Notables ‒Steve Mann EyeTap ‒Thad Starner Tech Lead: Google Glass

5. Augmented Reality: Productization Coming to market ‒SpaceGlasses ‒Glass ‒castAR ‒…

6. Augmented Reality: Productization Coming to market ‒SpaceGlasses ‒Glass ‒castAR ‒… ‒All of them have a camera!

7. Privacy Concerns Banned at restaurants Concerns about personal information and “hackers”

8. RESEARCH DESIGN

9. Research Goal Investigating underlying issues of augmented reality and privacy via in-situ interviews

10. In-Situ Interviews with Bystanders Observation & semi- structured interviews in cafes ‒12 field sessions ‒8 cafes ‒Spring & Summer 2013 ‒31 participants

11. Field Sessions Researcher pair (F/M): A.Researcher observing and interviewing B.Researcher wearing mock AR device

12. Semi-structured Interviews 1.Did you notice the glasses that (s)he’s wearing? What about them did you notice? 2.Have you heard about those kinds of glasses? What have you heard? 3.Did you know that those kinds of glasses have electronics and a display attached? 4.Did you know that you can record video with those kinds of glasses? 5.Why do you think someone would want to wear those kinds of glasses? 6.Do you think recording with those glasses is similar to recording with a cell phone? Why? 7.How do you feel about being around someone who is wearing those kinds of glasses? Why? 8.Would you want someone with those kinds of glasses to ask your permission before recording a video? 9.Would you be willing to wear something that would block someone from being able to record you? 1.Did you notice the glasses that (s)he’s wearing?

13. RESULTS

14. AR Interview Results: Bystander Reactions Bystander reactions ranged (predominantly indifferent or negative) 1/3 of participants did not notice the glasses

15. AR Interview Results: Bystander Reactions Bystander reactions ranged (predominantly indifferent or negative) 1/3 of participants did not notice the glasses

16. AR Interview Results: Permission & Notification Over 1/2 of participants would want to be asked permission – If they were the focus of recording – If it was feasible Some participants expressed interest in blocking technologies

17. AR Interview Results: Permission & Notification Over 1/2 of participants would want to be asked permission – If they were the focus of recording – If it was feasible Some participants expressed interest in blocking technologies The participants felt a sense of Helplessness

18. MITIGATIONS

19. Mitigations Not a new problem Untrustworthy Devices – Facial Recognition Disruption – Laser pointers – “Fists” Trustworthy Devices – World-Driven Access Control, Roesner et. al. – PlaceAvoider, Templeman et. al.

20. Helplessness “I would want them to ask -- as a courtesy. But legally there’s not much you can do. It’s like the Google founder said in 2007, or 2006, ‘privacy is dead.’ It ‘doesn’t exist anymore.’ It doesn’t bother me that much anymore.”
