Mobile location based services (LBS) often ask users to consent to over disclose location data in exchange for their service. This online experiment manipulated interface features within an LBS consent screen to understand their independent and interactive influence on location data obscurity decisions. Participants (N = 502) were led to believe they were involved in a location-tracking study, allowing for revealed preferences in their decisions. Results indicate that social proof and willingness-to-accept framing positively influenced participants’ likelihood to obscure their location data. While the presence of friction and defaults had no direct effect, both interacted with other interface features in influencing decision-making.

Digital experiences capture an increasingly large part of life, making them a preferred, if not required, method to describe and theorize about human behavior. Digital media also shape behavior by enabling people to switch between different content easily, and create unique threads of experiences that pass quickly through numerous information categories. Current methods of recording digital experiences provide only partial reconstructions of digital lives that weave - often within seconds - among multiple applications, locations, functions and media. We describe an end-to-end system for capturing and analyzing the "screenome" of life in media, i.e., the record of individual experiences represented as a sequence of screens that people view and interact with over time. The system includes software that collects screenshots, extracts text and images, and allows searching of a screenshot database. We discuss how the system can be used to elaborate current theories about psychological processing of technology, and suggest new theoretical questions that are enabled by multiple time scale analyses. Capabilities of the system are highlighted with eight research examples that analyze screens from adults who have generated data within the system. We end with a discussion of future uses, limitations, theory and privacy.
