Tension Space Analysis: Exploring Community Requirements for Networked Urban Screens

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. Researchers wishing to be led by a diverse user community may find that the priorities of some users, directly oppose the wishes of others. Previous literature suggests such tensions can be handled by ‘goal balancing’, where all requirements are reduced down to one set of essential, implementable attributes. Contrasting this, this paper’s contribution is ‘Tension Space Analysis’, which broadens and extends existing work on Design Tensions. It includes new domains, new representational methods and offers a view on how to best reflect conflicting community requirements in some aspects or features of the design.

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.

Considering Communities, Diversity and the Production of Locality in the Design of Networked Urban Screens

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 when deploying interactive situated technologies in public spaces. This paper investigates community and place building within a complex multicultural context. We approached this using ethnography, complemented with workshops in the wild. By studying the relationships arising between different segments of the community and two networked screen nodes, we examine the place building activities of residents, and how screen nodes are incorporated into them. Our research suggests that urban screens will be framed (and eventually used) as part of this continuing process of social, spatial and cultural construction. This highlights the importance of enabling socially meaningful relations between the people mediated by these technologies.

A Report on the First International Workshop on Research Methods in Animal-Computer Interaction

Animal-Computer Interaction (ACI) is a new and quickly developing discipline, which is closely related to HCI and is making reference to some of its theoretical frameworks and research methodologies. The first edition of the Workshop on Research Methods in ACI (RM4ACI) was co-located with the Third International Conference on Animal-Computer Interaction, which took place in Milton-Keynes, UK in November 2016. This paper presents an overview of the workshop, including insights from discussions on some of the challenges faced by the ACI community as it works to develop ACI as a discipline, and on important opportunities for cross-fertilization between HCI and ACI that the HCI community could consider.

Screens in the Wild: Exploring the Potential of Networked Urban Screens for Communities and Culture

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 well as UK-wide.

Evaluating a Public Display Installation with Game and Video to Raise Awareness of Attention Deficit Hyperactivity Disorder

Networked Urban Screens offer new possibilities for public health education and awareness. An information video about Attention Deficit Hyperactivity Disorder (ADHD) was combined with a custom browser-based video game and successfully deployed on an existing research platform, Screens in the Wild (SitW). The SitW platform consists of 46-in. touchscreen or interactive displays, a camera, a microphone and a speaker, deployed at four urban locations in England. Details of the platform and software implementation of the multimedia content are presented. The game was based on a psychometric continuous performance test. In the gamified version of the test, players receive a score for correctly selected target stimuli, points being awarded in proportion to reaction time and penalties for missed or incorrect selections. High scores are shared between locations. Questions were embedded to probe self-awareness about ‘attention span’ in relation to playing the game, awareness of ADHD and Adult ADHD and increase in knowledge from the video. Results are presented on the level of public engagement with the game and video, deduced from play statistics, answers to the questions and scores obtained across the screen locations. Awareness of Adult ADHD specifically was similar to ADHD in general and knowledge increased overall for 93 % of video viewers. Furthermore, ratings of knowledge of Adult ADHD correlated positively with ADHD in general and positively with knowledge gain. Average scores varied amongst the sites but there was no significant correlation of question ratings with score. The challenge of interpreting user results from unsupervised platforms is discussed.

Longitudinal, cross-site and "in the Wild": a study of public displays user communities' situated snapshots

Networked public displays are a new medium, and as such they can improve the quality and experience of urban spaces by providing new means to engage members of place-based communities. As they are located in different public spaces understanding commonalities and differences between their users helps in building a solid foundation for knowledge on how networked public displays operate. In this paper, we describe findings from a 12 weeks deployment of the Moment Machine application that allows posting and viewing situated snapshots across 4 displays placed in urban settings of the Screens in the Wild Network (UK). We describe similarities/differences between the four user communities in terms of the photos taken, returning users behavior, interaction session properties etc. Overall, our findings contribute to the buildup of knowledge on general engagement patterns of networked public displays. We suggest that situated snapshots and their analysis as described in this paper can be used as a research tool and methodology for capturing and uncovering the part of a place-based community interested in interacting with public displays.

Light-keypad interaction through coated double glazing

Interaction through glass has been demanding in industry, business, education, advertising and entertainment fields. Different technologies exist and work in varied circumstances. For example: acoustics or vibration detection, computer vision, capacitive interactive foils, infrared and others. The existing technologies tend to not work reliably through double-glazing and in outdoors conditions. This paper introduces an easy-to-implement, inexpensive solution, which is using light sensors to detect human actions and to interact with a computer. Light-Keypad can be used on any transparent medium, including through thick, coated double-glazing. This is a non-intrusive interactive method that may be used on existing objects and structures without modifying them. The prototype product has been used successfully in our current research project exploring the urban impact of digital screens.
