Mobile devices are playing an increasingly intimate role in everyday life. However, users can be surprised when informed of the data collection and distribution activities of apps they install. We report on two studies of smartphone users in western European countries, in which users were confronted with app behaviors and their reactions assessed. Users felt their personal space had been violated in "creepy" ways. Using Altman's notions of personal space and territoriality, and Nissenbaum's theory of contextual integrity, we account for these emotional reactions and suggest that they point to important underlying issues, even when users continue using apps they find creepy.

Ubiquitous computing has a grand vision. Even the name of the area identifies its universalizing scope. In this, it follows in a long tradition of projects that attempt to create new models and paradigms that unite disparate, distributed elements into a large conceptual whole. We link concerns in ubiquitous computing into a colonial intellectual tradition and identify the problems that arise in consequence, explore the locatedness of innovation, and discuss strategies for decolonizing ubicomp's research methodology.

Researchers and designers are increasingly creating technologies intended to support urban mobility. However, the question of what mobility is remains largely under-examined. In this paper we will use the notion of aesthetic journeys to reconsider the relationship between urban spaces, people and technologies. Fieldwork on the Orange County bus system and in the London Underground leads to a discussion of how we might begin to design for multiple mobilities.

Based on ethnographically-inspired research in Japan, we report on people's experiences using digital money payment systems that use Sony's FeliCa near-field communication smartcard technology. As an example of ubiquitous computing in the here and now, the adoption of digital money is found to be messy and contingent, shot through with cultural and social factors that do not hinder this adoption but rather constitute its specific character. Adoption is strongly tied to Japanese conceptions of the aesthetic and moral virtue of smooth flow and avoidance of commotion, as well as the excitement at winning something for nothing. Implications for design of mobile payment systems stress the need to produce open-ended platforms that can serve as the vehicle for multiple meanings and experiences without foreclosing such possibilities in the name of efficiency.

What happens when the domains of HCI design and money intersect? This paper presents analyses from an ethnographic study of virtual currency use in China to discuss implications for game design, and HCI design more broadly. We found that how virtual currency is perceived, obtained, and spent can critically shape gamers' behavior and experience. Virtual and real currencies can interact in complex ways that promote, extend, and/or interfere with the value and character of game worlds. Bringing money into HCI design heightens existing issues of realness, trust, and fairness, and thus presents new challenges and opportunities for user experience innovation.

We analyze online gaming as a site of collaboration in a digital-physical hybrid. We ground our analysis in findings from an ethnographic study of the online game World of Warcraft in China. We examine the interplay of collaborative practices across the physical environment of China's Internet cafes and the virtual game space of World of Warcraft. Our findings suggest that it may be fruitful to broaden existing notions of physical-digital hybridity by considering the nuanced interplay between the digital and physical as a multi-dimensional environment or "ecology". We illustrate how socio-economics, government regulations and cultural value systems shaped a hybrid cultural ecology of online gaming in China.

One of the outcomes of massive adoption of technology is that much of daily technology use and consumption is embedded into "unremarkable" daily life routines. Occasionally, these routines undergo major shifts, often in conjunction with major life events such as marriage, birth of a child, or a residential move. We propose a model of settling into a new location as a function of balance between the pull of the things left behind and the demands of the new and unknown. It is through this experience of being unsettled that we explore the processes of behavior adjustment and re-evaluation of old patterns of technology use as it relates to the old location and the demands of the new location.

The three primary thrusts of this paper are: first, that people do not think enough about their own privacy, in particular, they may not know enough about their privacy that they can really make informed decisions about sharing information; second, that technologies exist that can mitigate some of the problems associated with information sharing; and third, that services (in addition to to technologies) might be a reasonable way to think about addressing the privacy problem.

The Casablanca project explored how media space concepts could be incorporated into households and family life. This effort included prototypes built for the researchers' own home use, field studies of households, and consumer testing of design concepts. A number of previously unreported consumer preferences and concerns were uncovered and incorporated into several original prototypes, most notably ScanBoard and the Intentional Presence Lamp. Casablanca also resulted in conclusions about designing household social communication devices.

The primary focus of this article is an analysis of an audio-only media space from a computer-supported cooperative work (CSCW) perspective. To explore whether audio by itself is suitable for shared media systems, we studied a workgroup using an audio-only media space. This media space, called Thunderwire, combined high-quality audio with open connec-tions to create a shared space for its users. The two-month field study provided a richly nuanced understanding of this audio spaces social use. The system afforded rich sociable interactions. As well, users were able to create a useful, usable social space; however, through an analysis of the social norms that the participants formulated, we show that they had to take into account being in an audio-only environment. Within the field study, then, audio by itself was sufficient for a usable media space and a useful social space, but users were forced to adapt to many audio-only and system conditions. The article also considers audios implications for privacy.
