Beyond the Individual: The Contextual Wheel of Practice as a Research Framework for Sustainable HCI
Addressing human impact on the environment by focusing on shared everyday practices, rather than just individual behavior is an approach that shows promise. However, it can be challenging to put this approach into concrete use, especially in teams unfamiliar with the practice orientation. To support the practice approach, we introduce the Contextual Wheel of Practice (COWOP), a framework that can: 1) help researchers and designers to better understand practices, 2) design effective interventions, and 3) facilitate collaboration between team members from different disciplines, who may not be familiar with the practice orientation. We describe how COWOP was developed, and our experiences using COWOP in three different cases. We then position COWOP as part of the "turn to practice" in HCI, and discuss how it can be useful to HCI researchers and be applied in domains beyond sustainability, such as healthcare and privacy
Follow My Recommendations: A Personalized Privacy Assistant for Mobile App Permissions
Modern smartphone platforms have millions of apps, many of which request permissions to access private data and resources, like user accounts or location. While these smartphone platforms provide varying degrees of control over these permissions, the sheer number of decisions that users are expected to manage has been shown to be unrealistically high. Prior research has shown that users are often unaware of, if not uncomfortable with, many of their permission settings. Prior work also suggests that it is theoretically possible to predict many of the privacy settings a user would want by asking the user a small number of questions. However, this approach has neither been operationalized nor evaluated with actual users before. We report on a field study (n=72) in which we implemented and evaluated a Personalized Privacy Assistant (PPA) with participants using their own Android devices. The results of our study are encouraging. We find that 78.7% of the recommendations made by the PPA were adopted by users. Following initial recommendations on permission settings, participants were motivated to further review and modify their settings with daily “privacy nudges.” Despite showing substantial engagement with these nudges, participants only changed 5.1% of the settings previously adopted based on the PPA's recommendations. The PPA and its recommendations were perceived as useful and usable. We discuss the implications of our results for mobile permission management and the design of personalized privacy assistant solutionsPresented at the 12th Symposium on Usable Privacy and Security (SOUPS) 2016, June 22–24, 2016, Denver, Colorado.</div
