This paper borrows ideas from social science to inform the design of novel "sensing" user-interfaces for computing technology. Specifically, we present five design challenges inspired by analysis of human-human communication that are mundanely addressed by traditional graphical user interface designs (GUIs). Although classic GUI conventions allow us to finesse these questions, recent research into innovative interaction techniques such as `Ubiquitous Computing' and `Tangible Interfaces' has begun to expose the interaction challenges and problems they pose. By making them explicit we open a discourse on how an approach similar to that used by social scientists in studying human-human interaction might inform the design of novel interaction mechanisms that can be used to handle human-computer communication accomplishments.

ABSTRACT: The increasing convergence and mobility of digital network technologies have given rise to new, massively-scaled modes of social interaction where the physical and virtual worlds meet. This paper explores one product of these extreme networks, the emergent genre of immersive entertainment, as a potential tool for harnessing collective action. Through an analysis of the structure and rhetoric of immersive games, I explore how immersive aesthetics can generate a new sense of social agency in game players, and how collaborative play techniques can instruct real-world problem-solving.

Computer programming environments for learning should make it easy to create worlds of responsive and autonomous objects, such as video games or simulations of animal behavior. But building such worlds remains difficult, partly because the models and metaphors underlying traditional programming languages are not particularly suited to the task. This dissertation investigates new metaphors, environments, and languages that make possible new ways to create programs -- and, more broadly, new ways to think about programs. In particular, it introduces the idea of programming with "agents" as a means to help people create worlds involving responsive, interacting objects. In this context, an agent is a simple mechanism intended to be understood through anthropomorphic metaphors and endowed with certain lifelike properties such as autonomy, purposefulness, and emotional state. Complex behavior is achieved by combining simple agents into more complex structures. While the agent metaphor enables...

While surprisingly little has been written about context at a meaningful level, context is central to most theoretical approaches to information seeking. In this essay I explore in more detail three senses of context. First, I look at context as equivalent to the situation in which a process is immersed. Second, I discuss contingency approaches that detail active ingredients of the situation that have specific, predictable effects. Third, I examine major frameworks for meaning systems. Then, I discuss how a deeper appreciation of context can enhance our understanding of the process of information seeking by examining two vastly different contexts in which it occurs: organizational and cancer-related, an exemplar of everyday life information seeking. This essay concludes with a discussion of the value that can be added to information seeking research and theory as a result of a deeper appreciation of context, particularly in terms of our current multi-contextual environment and individuals taking an active role in contextualizing.

This paper was originally prepared for presentation to the seminar series on social and institutional change at the Robert Wood Johnson Foundation, Princeton, N.J., organized by Paul DiMaggio. I appreciate the insightful comments of Art Stinchcombe on the earlier draft.

This paper argues that in addition to the familiar approach using formal contexts, there is now a need in artificial intelligence to study contexts as social constructs. As a successful example of the latter approach, I draw attention to `interpretation' (in the sense of literary theory), viz. the reconstruction of intended meaning of a literary text that takes into account the context in which the author assumed the reader would place the text. An important contribution here comes from Wendell Harris, enumerating the seven crucial dimensions of context: knowledge of reality, knowledge of language, and the authorial, generic, collective, specific, and textual dimensions. Finally, two recent approaches to interpretation, due to Jon Barwise and Jerry Hobbs, are analyzed as useful attempts which also come to grips with the notion of context. It must be noted that there has been a considerable body of contributions connecting linguistic structure with social context. For example, anthropo...

To fully appreciate the opportunities provided by interactive and ubiquitous multimedia to record and share experiences, we report on an ethnographic investigation on the settings and nature of human memory and experience at a large-scale event. We studied two groups of spectators at a FIA World Rally Championship in Finland, both equipped with multimedia mobile phones. Our analysis of the organization of experience-related activities in the mass event focuses on the active role of technology-mediated memories in constructing experiences. Continuity, reflexivity in regard to the Self and the group, maintaining and re-creating group identity, protagonism and active spectatorship were important social aspects of the experience and were directly reflected in how multimedia was used. Particularly, we witnessed multimedia-mediated forms of expression such as staging, competition, storytelling, joking, communicating presence, and portraying others; and the motivation for these stemmed from the engaging, processual, and shared nature of experience. Moreover, we observed how temporality and spatiality provided a platform for constructing experiences. The analysis advocates applications that not only store or capture human experience for sharing or later use but also actively participates in the very construction of experience. The approach conveys several valuable design implications.
