Users' Privacy Concerns About Wearables: Impact of form factor, sensors and type of data collected
3 likes929 views
The document discusses users' privacy concerns regarding wearable devices, particularly focusing on how device form factors, sensors, and data types affect user perceptions. It identifies prevalent issues such as location and speech disclosure, highlighting methods users employ to mitigate risks. The analysis is based on data from various sources and emphasizes the need for designers to consider these privacy implications when developing wearable technology.

Users' Privacy Concerns About Wearables: Impact of form factor, sensors and type of data collected

- 2. Acknowledgements Support: NSF: 1314342 I’m especially thankful to: • Vivian Mo0 • Jacob Sorber • David Kotz • Ryan Halter • Amulet team • hatlab members HATlab!
- 6. Human Factors • Underexplored – Threats, risks, implicaRons for designers • Devise beSer soluRons to – Ensure users’ privacy – Ensure privacy of those around wearer – By understanding their perspecRves 6
- 7. Methods • April and May 2014 • 38 devices • 59 sources – 15 forums – 34 technical websites – 6 e-‐commerce websites – 4 social media sites • E.g., Amazon, • BestBuy • ExpertReviews • Reddit • Slate • Wearable CompuRng Review
- 8. Methods • > 2,000 comments • filtered privacy-‐related comments – 72 comments • Categorized comments – E.g., “locaRon disclosure”
- 11. Results
- 12. Avoid Avoid listening Avoid using device/ system Censor self Hiding SelecRve Sharing Control/ Modify Be careful Alter for audience Not in front of others Quietly Use code or different language MiRgate/ Alleviate Ask to remove Ask to not share Check Destroy evidence Limit distribuRon Be Vague

- 16. Right to forget • ‘it gives a record of everything you’ve done, day in and day out, possibly even some things you don’t want to be reminded of’ 16
- 17. LocaRon disclosure • ‘… stalkers know where you are at all .mes of the day, know when you go to sleep, riding a car, or climbing a mountain’
- 18. Discreet Display • ‘the second screen will act as sort of a privacy screen, keeping folks from reading your texts by glancing at your wrist’
- 19. Surveillance • ‘[wearable devices are] the NSA's new best friend’
- 21. Speech Disclosure • ‘though you can’t mind people overhearing what you are saying’
- 22. Surrep==ous Audio and Video Recording • Social norms already frown on making surrep==ous audio recordings (though it isn't illegal, it is done only infrequently and with an air of "secret agency" about it); video is much more of an intrusion.’
- 23. Sousveillence • ‘There's also another challenge that affects not only those who wear Glass, but everyone else around privacy’
- 26. Conclusion • privacy concerns are related to type of sensors/ data – Cameras and microphones – GPS – Displays • Similar to mobile privacy concerns – ExcepRon : increasing invisibility of wearables
- 28. Invisibility
