A diary study of mobile information needs [abstract]
Authors: Timothy Sohn, Kevin A. Li, William G. Griswold, and James D. Hollan (UC San Diego)
Abstract: Being mobile influences not only the types of information people seek but also the ways they attempt to access it. Mobile contexts present challenges of changing location and social context, restricted time for information access, and the need to share attentional resources among concurrent activities. Understanding mobile information needs and associated interaction challenges is fundamental to improving designs for mobile phones and related devices. We conducted a two-week diary study to better understand mobile information needs and how they are addressed. Our study revealed that depending on the time and resources available, as well as the situational context, people use diverse and, at times, ingenious ways to obtain needed information. We summarize key findings and discuss design implications for mobile technology.
Accountabilities of presence: reframing location-based systems [abstract]
Authors: Emily Troshynski, Charlotte Lee and Paul Dourish (UC Irvine)
Abstract: How do mobility and presence feature as aspects of social life? Using a case study of paroled offenders tracked via Global Positioning System (GPS), we explore the ways that location-based technologies frame people’s everyday experiences of space. In particular, we focus on how access and presence are negotiated outside of traditional conceptions of “privacy.” We introduce the notion of accountabilities of presence and suggest that it is a more useful concept than “privacy” for understanding the relationship between presence and sociality.
