Interaction Design: Foundations, Experiments

Interaction Design: Foundations, Experiments is the result of a series of projects, experiments and curricula aimed at investigating the foundations of interaction design in particular and design research in general. The first part of the book - Foundations - deals with foundational theoretical issues in interaction design. An analysis of two categorical mistakes -the empirical and interactive fallacies- forms a background to a discussion of interaction design as act design and of computational technology as material in design. The second part of the book - Experiments - describes a range of design methods, programs and examples that have been used to probe foundational issues through systematic questioning of what is given. Based on experimental design work such as Slow Technology, Abstract Information Displays, Design for Sound Hiders, Zero Expression Fashion, and IT+Textiles, this section also explores how design experiments can play a central role when developing new design theory

Expressive entities:An Exploration and Critical Reflection on Poetic Engagements with Technology

The overarching motivation of this thesis is to open new ideas on designing aesthetic interactions in everyday technology, moving beyond goal-directed utility to more nuanced, experimental, and even challenging interactions. My research endeavor is to impact human value by creating critical and imaginative technology-human relations. In particular, I design digital expressiveness to accommodate sensitive human sides before highlighting digital beings’ effective performances. In doing so, I strive for expressive yet thoughtful computational embodiments that empower humans to be expressive, reflective, explorative, and connected to each other. To bring these conceptual experimentations into tangible experiences in people’s lives, my research is based on designing interactive artifacts called “Expressive Entities”. To carry on this research outline above, I pursue an integrated approach from 1) conceptual and 2) methodological sides to steer 24 design explorations that underpin this thesis. First, I built conceptual experimentations on imagining what could present “Poetic Engagements with Technology”. Essentially, Poetic Engagements allow humankind to be protagonists who feel, sense, perceive, choose, and appropriate the engagements with technology, and avoid defining human beings from a generalized and filtered result through a technological lens. The outcome of this conceptual framework is composed of Four Poetic Interaction Possibilities: Expressive, Felt, Meditative, and Ludic Tech. Second, I open methodological development that bridges the conceptual exploration to design practice through “Experimental Making”. In particular, I propose art practice strategies and values in designing through three practice components, Defamiliarization, Creativity, and Imagination. This approach incorporates critical design perspective and imaginative ideas into material explorations and fluid assemblages for designing new aesthetic interactions. These two main research streams are correlated and complementary, introducing new concepts, embedding metaphors, and developing sensual aesthetics to expand thoughtful human-technology relations, bringing poetic experiences into life

Intentions to use mobile services: Antecedents and cross-service comparisons

-This article develops and tests a model to explain consumers' intention to use mobile services. Through triangulating theories from the diverse fields of information systems research, uses and gratification research, and domestication research, the authors put forth an integrated model that explains intention to use mobile services. The model proposes four overall influences on usage intention: motivational influences, attitudinal influences, normative pressure, and perceived control. The authors study the type of interactivity and process characteristics associated with the service that moderate the effects on the relationship between the proposed antecedents and usage intention. The results from empirical studies of four mobile services show strong support for the effects of motivational influences, attitudinal influences, normative pressure, and perceived control on consumers' intentions to use mobile services. Some of the effects are moderated by process characteristics (goal-directed vs. experiential services) that are associated with the service.This article develops and tests a model to explain consumers' intention to use mobile services.

Teaching Poetry With New Media

Artigo realizado no âmbito do projecto "PO.EX'70-80 Arquivo Digital da Literatura Experimental Portuguesa", com a Refª PTDC/CLE-LLI/098270/2008, financiado por fundos nacionais através da FCT/MCTES (PIDDAC) e co-financiado pelo Fundo Europeu de Desenvolvimento Regional (FEDER) através do COMPETE – Programa Operacional Factores de Competitividade (POFC).The purpose of this paper is to discuss the use of interactive multimedia and hypertextual tools in literature classes. It argues for the promotion of multimedia programming within the context of creative writing, describing activities related to the conception and development of hypermedia projects in academic contexts. The first part is made up of a discussion of theoretical positions. We will provide an overview of studies about the relationship between literature and digital media. The second part of this paper will show how it is possible to articulate literary concepts such as multi-modality, intertextuality, reader-response and cooperation, with digital tools dealing with algorithms, combinatory techniques, multimedia programming, and networked hypertext. We will provide an account of projects involving the creation and recreation of experimental poetry in digital media, and through the discussion of other examples of the use of new media to teach poetry.info:eu-repo/semantics/publishedVersio

Ubiquitous Advertising in Emerging Market, An Empirical Study on the Adoption and Continuous Usage of SMS Advertising in Tanzania

The ubiquity characteristic of SMS message persuade the marketers to extend market coverage through the adoption of mobile advertisiment. SMS became the new innovated opportunity of marketing communication, which is the easier method in delivery of advertising messages. This opportunity cannot be granted without the consumer’s willingness to adopt this new media to be their marketing communication channel. This article determine the behavior intention to adopt SMS advertising among mobile phone users in Tanzania. Applying the extended UTAUT2 model extending with content design to explore the motivating factors on adoption intention. Linear Regression analysis and Structural Equation Model in Amos LISREAL method version21 used. Results statistically confirms performance expectancy, effort expectancy, social norms, content design and hedonic motivation have effect on behavior intention to adopt the SMS advertising.  Uses of the phone (text message) significantly affected by performance expectancy in predicting the continuous usage of SMS ad. Facilitating condition reveled no effect on the adoption of SMS ad. Adoption of SMS ad significantly moderated by age and education, while gender has no effect. The study provide insight in proper segmentation of the market, designing relevant content that are user friendly and gratify the consumers’ goal oriented before embarking to new innovated SMS advertisement channel. Limitation has been cited and proposed for further research. Keywords: Ubiquity, SMS advertising, Adoption

Enhancing Physical Objects with Actuated Levitating Particles

We describe a novel display concept where levitating particles are used to add a dynamic display element to static physical objects. The particles are actuated using ultrasound, for expressive output without mechanical constraints. We explore novel ways of using particles to add dynamic output to other objects, for new interactive experiences. We also discuss the practical challenges of combining these. This work shows how the unique capabilities of levitation can create novel displays by enhancing another form of media

When humans form media and media form humans: an experimental study examining the effects different digital media have on the learning outcomes of students who have different learning styles

A set of computer-based experiments are reported that investigate the understanding achieved by learners when studying a complex domain (statistics) in a real E-learning environment using three different media combinations – Text only, Text and Diagrams and Spoken Text and Diagrams, and the results agree with earlier work carried out on more limited domains. The work is then extended to examine how student interaction and student learning styles affect the learning outcomes. Different responses to the media combinations are observed and significant differences occur between learners classified as Sensing and Reflective learners. The experiment also identified some important differences in performance with the different media combinations by students registered as Dyslexic. The experiment was therefore repeated with a much larger sample of Dyslexic learners and the earlier effects were found to be significant. The results were surprising and may provide useful guidance for the design of material for Dyslexic students

A white right hand

“The final, definitive version of this article has been published in the Journal, Convergence, Vol 17 issue 3, 2011, © SAGE Publications Ltd, 2011: on SAGE Journals Online: http://online.sagepub.com/”The hand icon apparent on desktop and laptop computer screens is shown to manifest an unexpected cultural history. What may have been taken for granted in the implementation of graphical user interfaces and their associated iconography, is subjected to a semiotic analysis that reveals a basis in blackface minstrelsy. Theories of human interactivity with computers help to explain how this heritage has remained relatively hidden.Peer reviewe

Difficult forms: critical practices of design and research

As a kind of 'criticism from within', conceptual and critical design inquire into what design is about – how the market operates, what is considered 'good design', and how the design and development of technology typically works. Tracing relations of conceptual and critical design to (post-)critical architecture and anti-design, we discuss a series of issues related to the operational and intellectual basis for 'critical practice', and how these might open up for a new kind of development of the conceptual and theoretical frameworks of design. Rather than prescribing a practice on the basis of theoretical considerations, these critical practices seem to build an intellectual basis for design on the basis of its own modes of operation, a kind of theoretical development that happens through, and from within, design practice and not by means of external descriptions or analyses of its practices and products
