Mancini, Clara, Rogers, Yvonne, Thomas, Keerthi, Joinson, Adam N., Price, Blaine A., Bandara, Arosha K., Jedrzejczyk, Lukasz and Nuseibeh, Bashar (2011): In the best families: tracking and relationships. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 2419-2428.

A growing body of research has been exploring the use of control mechanisms to address the privacy concerns raised by location-tracking technology. We report on a qualitative study of two family groups who used a custom-built tracking application for an extended period of time. Akin to sociological breaching experiments, the study focuses on the interferences between location tracking and relationship management. We analyze the tensions that can arise between affordances of the technology and uses that the contracts between family members legitimize. We describe how, by fostering misperceptions and 'nudging' behaviors, location-tracking technology can generate anxieties and conflicts even in close relationships. We discuss their vulnerability to the overreaching effects of tracking, against which the use of mechanisms such as location-sharing preferences and feedback may not be socially viable.

Jedrzejczyk, Lukasz, Price, Blaine A., Bandara, Arosha and Nuseibeh, Bashar (2010): "Privacy-shake",: a haptic interface for managing privacy settings in mobile location sharing applications. In: Proceedings of 12th Conference on Human-computer interaction with mobile devices and services 2010. pp. 411-412.

We describe the "Privacy-Shake", a novel interface for managing coarse grained privacy settings. We built a prototype that enables users of Buddy Tracker, an example location sharing application, to change their privacy preferences by shaking their phone. Users can enable or disable location sharing and change the level of granularity of disclosed location by shaking and sweeping their phone. In this poster we present and motivate our work on Privacy-Shake and report on a lab-based evaluation of the interface with 16 participants.

Jedrzejczyk, Lukasz, Price, Blaine A., Bandara, Arosha K. and Nuseibeh, Bashar (2010): On the impact of real-time feedback on users' behaviour in mobile location-sharing applications. In: Proceedings of the 2010 Symposium on Usable Privacy and Security 2010. p. 14.

Effective privacy management requires that mobile systems' users be able to make informed privacy decisions as their experience and knowledge of a system progresses. Prior work has shown that making such privacy decisions is a difficult task for users because systems do not provide support for awareness, visibility and accountability when sharing privacy-sensitive information. This paper reports results of our investigation into the efficacy of realtime feedback as a mechanism for incorporating these features of social translucence in location-sharing applications, in order to help users make better privacy decisions. We explored the role of real-time feedback in the context of Buddy Tracker, a mobile location-sharing application. Our work focuses on ways in which real-time feedback affects people's behaviour in order to identify the main criteria for acceptance of this technology. Based on the data from a three week field trial of Buddy Tracker, a focus group session, and interviews, we found that when using a system that provided real-time feedback, people were more accountable for their actions and reduced the number of unreasonable location requests. We have used the results of our study to propose high-level design criteria for incorporating real-time feedback into information sharing applications in a manner that ensures social acceptance of the technology.

Mancini, Clara, Rogers, Yvonne, Bandara, Arosha K., Coe, Tony, Jedrzejczyk, Lukasz, Joinson, Adam N., Price, Blaine A., Thomas, Keerthi and Nuseibeh, Bashar (2010): Contravision: exploring users' reactions to futuristic technology. In: Proceedings of ACM CHI 2010 Conference on Human Factors in Computing Systems 2010. pp. 153-162.

How can we best explore the range of users' reactions when developing future technologies that may be controversial, such as personal healthcare systems? Our approach -- ContraVision -- uses futuristic videos, or other narrative forms, that convey either negative or positive aspects of the proposed technology for the same scenarios. We conducted a user study to investigate what range of responses the different versions elicited. Our findings show that the use of two systematically comparable representations of the same technology can elicit a wider spectrum of reactions than a single representation can. We discuss why this is so and the value of obtaining breadth in user feedback for potentially controversial technologies.
