BACKGROUND
Augmented Reality Devices
• Augmented Reality: Vision‒ Sensing‒ Real-Time Context‒ Information Overlay
• Notables‒ Steve Mann• EyeTap
‒ Thad Starner• Tech Lead: Google Glass
Augmented Reality: Productization
• Coming to market‒ SpaceGlasses‒ Glass‒ castAR‒ …
Augmented Reality: Productization
• Coming to market‒ SpaceGlasses‒ Glass‒ castAR‒ …
‒ All of them have a camera!
Privacy Concerns
Banned at restaurants
Concerns about personal information and “hackers”
RESEARCH DESIGN
Research Goal
• Investigating underlying issues of augmented reality and privacy via in-situ interviews
In-Situ Interviews with Bystanders
• Observation & semi-structured interviews in cafes‒ 12 field sessions‒ 8 cafes‒ Spring & Summer 2013‒ 31 participants
Field Sessions
• Researcher pair (F/M):A. Researcher observing and
interviewingB. Researcher wearing mock
AR device
Semi-structured Interviews1. 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?
RESULTS
AR Interview Results: Bystander Reactions
• Bystander reactions ranged (predominantly indifferent or negative)
• 1/3 of participants did not notice the glasses
AR Interview Results: Bystander Reactions
• Bystander reactions ranged (predominantly indifferent or negative)
• 1/3 of participants did not notice the glasses
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
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
MITIGATIONS
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.
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.”
