Exploring the effect of spatial layout on mediated urban interactions

In this paper we focus on the spatial configuration and emergent social interactions in two locations in London mediated by interactive and networked urban displays. Our analysis draws upon interactions mediated through displays we implemented in the real world connecting four urban spaces [1]. We outline our case study and the methodology we implemented, including the analysis of the spatial layout on the micro/local scale in two sites, followed by the observations of social behavior and technologically mediated interactions by actors, spectators and passers-by during two community events, before finally outlining the following identified interaction zones: 1) direct interaction space surrounding the display (direct); 2) the surrounding public space (wide); and 3) across spatial boundaries i.e. the remotely connected space through networked displays (connected) over time. We highlight site-specific interactions and compare them to the more generic types of interactions, thus contributing to the understanding of mediated social interactions. We suggest that the properties of the spatial layout play a significant role and, to a certain extent, frame the type of interactions mediated through public displays. We highlight in particular the dynamic and interconnected nature of this mediation, defined through the spatial layout, people, type of social activities, and time of the day

Foreign objects? Web content management systems, journalistic cultures and the ontology of software

Research on ‘digital’ journalism has focused largely on online news, with comparatively less interest in the longer-term implications of software and computational technologies. Drawing upon a six-year study of the Toronto Star, this paper provides an account of TOPS, an in-house web content management system (CMS) which served as the backbone of thestar.com for six years. For some, TOPS was a successful software innovation, while for others, a strategic digital ‘property’. But for most journalists, it was slow, deficient in functionality, aesthetically unappealing and cumbersome. Although several organizational factors can explain TOPS’ obstinacy, I argue for particular attention to the complex ontology of software. Based on an outline of this ontology, I suggest software be taken seriously as an object of journalism, which implies: acknowledging its partial autonomy from human use or authorization; accounting for its ability to mutate indefinitely; and analyzing its capacity to encourage forms of ‘computational thinking

HUMAN INTERACTIONS IN PHYSICAL AND VIRTUAL SPACES: A GIS-BASED TIME-GEOGRAPHIC EXPLORATORY APPROACH

Information and communication technologies (ICT) such as cell phone and the Internet have extended opportunities of human activities and interactions from physical spaces to virtual spaces. The relaxed spatio-temporal constraints on individual activities may affect human activity-travel patterns, social networks, and many other aspects of society. A challenge for research of human activities in the ICT age is to develop analytical environments that can help visualize and explore individual activities in virtual spaces and their mutual impacts with physical activities. This dissertation focuses on extending the time-geographic framework and developing a spatio-temporal exploratory environment in a space-time geographic information system (GIS) to facilitate research of human interactions in both physical and virtual spaces. In particular, this dissertation study addresses three research questions. First, it extends the time-geographic framework to assess the impacts of phone usage on potential face-to-face (F2F) meeting opportunities, as well as dynamic changes in potential F2F meeting opportunities over time. Secondly, this study extends the time-geographic framework to conceptualize and represent individual trajectories in an online social network space and to explore potential interaction opportunities among people in a virtual space. Thirdly, this study presents a spatio-temporal environment in a space-time GIS to facilitate exploration of the relationships between changes in physical proximity and changes in social closeness in a virtual space. The major contributions of this dissertation include: (1) advancing the time-geographic framework in its ability of exploring processes of virtual communication alerting physical activity opportunities; (2) extending some concepts of the classical time geography from a physical space to a virtual space for representing and exploring virtual interaction patterns; (3) developing a space-time GIS that is useful for exploring patterns of individual activities and interactions in both physical and virtual spaces, as well as the interactions between these two spaces

Smart citizen sentiment dashboard: A case study into media architectural interfaces

In this paper we introduce the notion of media architectural interfaces (MAIs), which describe the relation between users engaging with dynamic content on media façades through tangible artifacts on street level. Firstly, we outline existing research concerned with public displays, urban screens and media facades, secondly we summarize related works that explore mediated urban interactions in connection with MAIs. We report on the technical set up of a field study, in which we deployed a novel tangible user interface (TUI), called the Smart Citizen Sentiment Dashboard (SCSD). This device gives citizens the opportunity to express their mood about local urban challenges. The input from this TUI is then instantly displayed on a very large (3700 sqm) media façade. The installation ran for three weeks during a media arts festival in Sao Paulo, Brazil. During this deployment period, we were able to gather data to help us understand the relationship between passers-by, participants, the TUI and the media façade. As a result we identified emergent behavior in the immediate space around the TUI and the wider urban space. The contribution this paper makes is in highlighting challenges in the design and deployment of large-scale media architectural interfaces.

Invisible City. A Multi-Sensory Approach to the Analysis of Urban Space

This thesis explores the relationship between sensory stimuli and human behaviour in urban space. It seeks to understand how spatial conditions, mediated, and supported by sensory experiences, impact individual and social activities and how this learning might be applied to other cities. This research aims to challenge the “visualism” of planning and urban design approaches and to examine the urban environment through a multi-sensory analysis, focusing on the non-visual senses, such as hearing, smell and touch. It is based on a qualitative case study approach focused on Bishopsgate, in the City of London, an area with a unique variety of urban spaces, compact morphology and land use. This thesis contributes to knowledge in three principal ways: First, the use of “sensewalks” and “sensetalks” as innovative user-centred methods of data collection, enabling in-situ semi-structured interviews with the presence of the researcher. Second, the use of thematic analysis of verbal and semantic descriptions received from participants, establishes a baseline for the exploration. Finally, the creation of a framework of analysis based on the concept of “sensescapes” will facilitate the future exploration of the urban setting through its different dimensions. This framework not only creates a baseline for discussion but also establishes a tool for use in future urban development within the fields of environmental psychology, sensory analysis, urban design and spatial planning. These contributions add to the academic literature and offer methods and techniques of analysis that may support future academic research, practice and policy. As planners and urban designers try to create better and healthier spaces, the analysis and production of urban “sensescapes” can be used as a tool in (re)designing the city in new ways that stimulate the senses – ultimately making the role of the non-visual senses more ‘visible’ in the urban setting

Visualization in cyber-geography: reconsidering cartography's concept of visualization in current usercentric cybergeographic cosmologies

This article discusses some epistemological problems of a semiotic and cybernetic character in two current scientific cosmologies in the study of geographic information systems (GIS) with special reference to the concept of visualization in modern cartography. Setting off from Michael Batty’s prolegomena for a virtual geography and Michael Goodchild’s “Human-Computer-Reality-Interaction” as the field of a new media convergence and networking of GIS-computation of geo-data, the paper outlines preliminarily a common field of study, namely that of cybernetic geography, or just “cyber-geography) owing to the principal similarities with second order cybernetics. Relating these geographical cosmologies to some of Science’s dominant, historical perceptions of the exploring and appropriating of Nature as an “inventory of knowledge”, the article seeks to identify some basic ontological and epistemological dimensions of cybernetic geography and visualization in modern cartography. The points made is that a generalized notion of visualization understood as the use of maps, or more precisely as cybergeographic GIS-thinking seems necessary as an epistemological as well as a methodological prerequisite to scientific knowledge in cybergeography. Moreover do these generalized concept seem to lead to a displacement of the positions traditionally held by the scientist and lay-man citizen, that is not only in respect of the perception of the matter studied, i.e. the field of geography, but also of the manner in which the scientist informs the lay-man citizen in the course of action in the public participation in decision making; a displacement that seems to lead to a more critical, or perhaps even quasi-scientific approach as concerns the lay-man user
