We describe the design process, technical concept and first insights from a lightweight in-the-wild evaluation of a movable interface for public places. Our wider aim is to understand how the environment can be utilized for novel interface types. Our moveable prototypes are an intermediate step that confirmed known behavioral patterns in public space but also revealed new ones (e.g. creative inclusion of urban furniture and trees) as a result of having multiple objects within a larger interaction space.

We examine the recent move from a rhetoric of “users” towards one of “makers”, “crafters”, and “hackers” within HCI discourse. Through our analysis, we make several contributions. First, we provide a general overview of the structure and common framings within research on makers. We discuss how these statements reconfigure themes of empowerment and progress that have been central to HCI rhetoric since the field’s inception. In the latter part of the paper, we discuss the consequences of these shifts for contemporary research problems. In particular, we explore the problem of designed obsolescence, a core issue for Sustainable Interaction Design (SID) research. We show how the framing of the maker, as an empowered subject, presents certain opportunities and limitations for this research discourse. Finally, we offer alternative framings of empowerment that can expand maker discourse and its use in contemporary research problems such as SID.

The Kinect for Xbox is a powerful motion sensing input device first released in 2010 as an optional peripheral for the Xbox 360, and more recently packaged with the Xbox One. While the Kinect has achieved widespread success in ‘casual’ motion games such as Kinect Sports or Just Dance, it has seen little uptake in ‘core’ game genres (such as first person shooters or role-play games). Our research provides an account of - and interrogates - existing uses of the Kinect in non-‘casual’ games. We have explored the positive and negative reception of the Kinect in these games based on online discussions, ‘Let’s Play’ videos and game reviews in order to understand successes and player frustrations. While many issues revolve around player virtuosity and control, in this abstract we discuss the contrasting implementations of voice in Tomb Raider and Splinter Cell to succinctly demonstrate a broader argument around the importance of considering player-identity in the use of ‘Natural User Interfaces’ (such as voice and gesture) in digital games.

This paper describes SynKu, a mobile application that merges audio and image processing with human interpretation to speculate on the production of sensory objects. Sensory objects are representations of sensory phenomena interpreted and used by both people and software. We discuss how the SynKu application enables us to explore how algorithms help to change and legitimate the reconstruction of sensory phenomena across self-tracking platforms.

As modern information communication technologies are increasingly integrated in our public environment, challenges arise to render them locally relevant and meaningful. In this paper, we describe the design and evaluation of StreetTalk, a set of situated public displays attached to house facades that were specifically designed to facilitate communication and interaction between households and their local neighborhood. We report on a participatory design process that resulted in a range of neighborhood communication concepts that reached beyond the traditional screen-based notion of public displays. Accordingly, three unique displays were deployed and critically evaluated during an eight-week in-the-wild field study, which aimed to describe the potential usefulness of making public displays more situated, such as by taking into account the individual preferences of households in terms of design and functionality, by exploring alternative means of public communication, and by facilitating content creation by lay households.

In this paper, we replicate a study of collaborative mobile phone use to share personal photos in groups of collocated people. The replication study was conducted in a different cultural context to check the generalizability of the findings from the original study in terms of the proposed interaction techniques, current photo sharing practices, and privacy. Our results confirm and expand the original findings. We report our main findings by comparing them to the key findings of the original study. Finally, we discuss possible reasons for some variance in the results.

Cognition, Communication and Interaction is an edited collection of articles that examine the theoretical and methodological
research issues that underlie the design and use of interactive technology. Present interactive designs are addressing the multi-modality of human interaction and the multi-sensory dimension of how we engage with each other. This book aims to provide
a trans-disciplinary research framework and methodology for interaction design. The analysis directs attention to three human capacities that our engagement with interactive technology has made salient and open to constant redefinition. These capacities are human cognition, communication and interaction.
In this book examination of these capacities is embedded in understanding the following foundations for design: concepts of “communication and interaction” and their application (Part 1); conceptions of “knowledge and cognition” (Part 2); the role of
aesthetics and ethics in design (Part 3).
This book explores how digital technology is altering the relationships between people and how the very nature of interface itself needs to be reconsidered to reflect this – how we can make sense of each other, handle ambiguities,... more
This book explores how digital technology is altering the relationships between people and how the very nature of interface itself needs to be reconsidered to reflect this – how
we can make sense of each other, handle ambiguities, negotiate differences, empathise and collectively make skilled judgments in our modern society. The author presents new directions for research at the relational-transactional intersection of contrasting disciplines of arts, science and technology,and in so doing, presents philosophical and artistic questions for future research on human connectivity in our digital age.

▶ Introduces the relational interface, which questions the historical idea of the interface as a conduit of the transactional and addresses an aesthetic and ethical balance
▶ Formulates tacit engagement as an emerging concept for the study of human relations
▶ Proposes a fundamental framework of mediation for expertise and decision making in complex human systems
▶ Critiques the concept of data and what makes for the success of knowledge transfer

The Pay-E-Safe system is a token-based car battery
powered electronic micropayment system for emerging
markets in East Africa. This is the story of how it was
developed with different ethnic groups in Kasese,
Uganda, combining methods from HCI, software
development, and business modeling. We created a
system that is inexpensive to implement, sensitive to
the Ugandan context (e.g. low incomes, unreliable
power supplies and unstable Internet connections) and
provides benefits to local vendors as well as added
value to users and their families. Using observations,
interviews and prototype evaluations with local
Ugandans we studied people’s spending behaviors and
then explored alternative design solutions with them.
Along the way, we discovered that a micropayment
system could actually add value to the user experience
beyond the exchange of money for services. This case
study reports on how we designed the system and the
additional value it afforded users.

In this paper, we introduce a first pass of a rhetorical handbook intended for UI/UX designers. This handbook is based on an earlier version for graphic designers, introduced by Ehses & Lupton in 1988, in which diverse rhetorical concepts are illustrated through graphic work. For the UI/UX version, we examined desktop, web and mobile interfaces in order to illustrate the same concepts. In this first pass, we observe that the three modes of appeal (i.e., pathos, ethos and logos) fluctuate throughout the user experience. Additionally, we learned that rhetorical operations aid describing the adjustments made on an interface to work in different platforms. Further, the rhetorical figures (tropes and schemes) help to describe conceptually the interface’s composition and interactions. The concepts presented in the handbook provide a framework to examine and critique user interfaces, through which the disciplines of user experience and rhetoric connect.

In this paper, we present ongoing research concerning the interaction between users and autonomous mobile agents in the environmental monitoring domain. The overarching project, DIADEM, deals with developing a system that detects potentially hazardous situations in populated industrial areas using input from both a distributed sensor network and humans through mobile devices. We propose a model of interaction with the gas detection system where concerned citizens communicate with a mobile agent to inform the gas monitoring system about unusual smells via their mobile phones. Next, we present a preliminary user requirements analysis based on 40 phone calls from members of the public to an environmental monitoring agency. Finally, we introduce measures to study the delicate long-term social relationship between users and the gas monitoring system.
