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.”

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.”
