This paper draws on the design process, implementation and early evaluation results of an urban screens network to highlight the tensions that emerge at the boundary between the technical and social aspects of design. While public interactive screens in urban spaces are widely researched, the newly emerging networks of such screens present fresh challenges.(More)
Large public displays are becoming a ubiquitous resource in the urban environment. Interconnected over the Internet these hitherto isolated " ad displays " could become a novel and powerful communication medium – net-worked public displays. One example for such a novel type of communication is their use as community tools. Scattered across the urban(More)
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,(More)
Urban screens are becoming a common element of our city landscape. As such they offer new ways of connecting people that occupy public space, e.g., by taking situated snapshots through a display-attached camera. In this paper we present a first longitudinal case study of 12 weeks of such an application -- Moment Machine -- deployed "in the wild" on an urban(More)
Highly diverse settings such as London (with people from ~179 countries speaking ~300 languages) are unique in that ethnic or socio-cultural backgrounds are no longer sufficient to generate a sense of place, belonging and community. Instead, residents actively perform place building activities on an ongoing basis, which we believe is of great importance(More)
In this paper, we describe our Research-in-the-Wild driven methodology to tackle a complex range of social, technical and interactional issues when implementing networked Urban Screens in London and Nottingham, UK [1]. The diversity of the local communities provides a unique opportunity for the research to examine interactions within the town centres, as(More)
In this paper we describe the VisAge project, which explored how a community-based Augmented Reality (AR) system could be used to tell stories and cultural histories about urban environments. Our work focussed on two main themes --- user engagement and immersiveness of the experience. To address the first theme, we developed an online portal where anybody(More)
In this paper we present the Augmented Urban Reality Project (AUR), developed by University College London in association with augmented reality specialists, Holition (UK). We designed and implemented an urban experience, which combines two screens during the Arts Trail in Leytonstone (UK): 1) the situated urban screen enabling sharing of photos taken by(More)
