The design with intent method: A design tool for influencing user behaviour

The official published version can be found at the link below.Using product and system design to influence user behaviour offers potential for improving performance and reducing user error, yet little guidance is available at the concept generation stage for design teams briefed with influencing user behaviour. This article presents the Design with Intent Method, an innovation tool for designers working in this area, illustrated via application to an everyday human–technology interaction problem: reducing the likelihood of a customer leaving his or her card in an automatic teller machine. The example application results in a range of feasible design concepts which are comparable to existing developments in ATM design, demonstrating that the method has potential for development and application as part of a user-centred design process

Just-In-Place Information for Mobile Device Interfaces

Abstract. This paper addresses the potentials of context sensitivity for making mobile device interfaces less complex and easier to interact with. Based on a semiotic approach to information representation, it is argued that the design of mobile device interfaces can benefit from spatial and temporal indexicality, reducing information complexity and interaction space of the device while focusing on information and functionality relevant here and now. Illustrating this approach, a series of design sketches show the possible redesign of an existing web and wap-based information service.

Tangible user interfaces : past, present and future directions

In the last two decades, Tangible User Interfaces (TUIs) have emerged as a new interface type that interlinks the digital and physical worlds. Drawing upon users' knowledge and skills of interaction with the real non-digital world, TUIs show a potential to enhance the way in which people interact with and leverage digital information. However, TUI research is still in its infancy and extensive research is required in or- der to fully understand the implications of tangible user interfaces, to develop technologies that further bridge the digital and the physical, and to guide TUI design with empirical knowledge. This paper examines the existing body of work on Tangible User In- terfaces. We start by sketching the history of tangible user interfaces, examining the intellectual origins of this field. We then present TUIs in a broader context, survey application domains, and review frame- works and taxonomies. We also discuss conceptual foundations of TUIs including perspectives from cognitive sciences, phycology, and philoso- phy. Methods and technologies for designing, building, and evaluating TUIs are also addressed. Finally, we discuss the strengths and limita- tions of TUIs and chart directions for future research

Exploring Interface Sign Ontologies for Web User Interface Design and Evaluation: A User Study

Part 2: Organizational Semiotics and ApplicationsInternational audienceThe aim of this paper is twofold: firstly, to find the set of ontologies (i.e., the set of concepts and skills) presupposed by users when interpreting the meaning of web interface signs (i.e., the smallest elements of web user interfaces), and secondly, to investigate users’ difficulties in interpreting the meanings of interface signs belonging to different kinds of ontologies. In order to achieve these aims an empirical user study was conducted with 26 test participants. The study data was gathered by semi-structured interviews and questionnaires. Following an empirical research approach, descriptive statistics and qualitative data analysis were used to analyze the data. The study results provide a total of twelve ontologies and reveal the users’ difficulties in interpreting the meanings of interface signs belonging to different kinds of ontologies

Exploring Cultural Differences in HCI Education

The discipline of human-computer interaction has become a subject taught across universities around the world, outside of the cultures where it originated. However, the intercultural implication of its assimilation into the\ud syllabus of courses offered by universities around the world remains underresearched. The purpose of this ongoing research project is to provide insights for these implications in terms of the student and teacher experience of HCI. How this subject is socially represented across the different universities studied is a key question. In order to develop intercultural awareness of these questions\ud universities from UK, Namibia, Mexico and China are collaborating in a multiple case study involving students and lecturers engaged in evaluation and design tasks. Findings will then be used to propose an international HCI curriculum more supportive of local perspectives. This paper describes the initial steps of this study and some preliminary findings from Namibia, India and Mexico about cognitive styles and cultural attitudes

e-Tourism and Culture through Virtual Art Galleries: A pilot study of the usability of an interface

Virtual tours of museums and galleries are becoming an increasingly common aspect of e-Tourism marketing. This paper reports on a usability pilot study that analyses the design of icons in a German 3-D virtual art gallery interface. It evaluates the extent to which a sample of typical computer users can interpret the meaning of icons from the interface taken ‘out of context’. This was done by assessing a sample of twenty-one icons representing the ‘action’, ‘information’ and ‘navigation’ functions. An Icon Intuitiveness Test (IIT) was used to measure their Icon Recognition Rate (IRR) and to classify them as ‘identifiable’, ‘mediocre’ or ‘vague’ according to an adapted stereotypy. The IIT results show that the meaning of almost 30% of the icons was misinterpreted or confused, which can seriously compromise the usability of an interface. Based on these findings, recommendations are made for icon redesign and replacement and it is concluded that further research is needed into the ‘learnability’ of icons and users’ understanding of icons in context. It is contended that increased usability leading to an improved user experience can have an economic impact on e-Tourism

Evaluating musical software using conceptual metaphors

An open challenge for interaction designers is to find ways of designing software to enhance the ability of novices to perform tasks that normally require specialized domain expertise. This challenge is particularly demanding in areas such as music analysis, where complex, abstract, domain-specific concepts and notations occur. One promising theoretical foundation for this work involves the identification of conceptual metaphors and image schemas, found by analyzing discourse. This kind of analysis has already been applied, with some success, both to musical concepts and, separately, to user interface design. The present work appears to be the first to combine these hitherto distinct bodies of research, with the aim of devising a general method for improving user interfaces for music. Some areas where this may require extensions to existing method are noted. This paper presents the results of an exploratory evaluation of Harmony Space, a tool for playing, analysing and learning about harmony. The evaluation uses conceptual metaphors and image schemas elicited from the dialogues of experienced musicians discussing the harmonic progressions in a piece of music. Examples of where the user interface supports the conceptual metaphors, and where support could be improved, are discussed. The potential use of audio output to support conceptual metaphors and image schemas is considered

My Crohn’s disease on real-time information - User experience improvement through cross-platform applications

Reducing hospital institutionalization of citizen with chronic diseases is a major priority of western countries priorities. The more complex the health condition, the harder it is to coordinate clinical care. To improve the disease management and control, most patients need to use mobile applications that are available in online stores or web services because of the difficulty that a personal mobile phone has to get real time access to clinical data outside of a hospital. In terms of IBD - Inflammatory Bowel Disease - existing mobile phone solutions are very complex, because visually the interfaces communicates with the user through inadequate use of symbols in clinical features, which are inconsistent and have poor legibility. They also presents a lack of visual optimization between multiplatform systems. This increases the user's learning curve in terms of how to interpret and interact with these systems, generating an opportunity for these patients with abilities to innovate through the creation and development of solutions that solve their own problems related to the management and coordination of the disease. This thesis aims to analysis IBD patients behaviour related to disease management, identify the type of problems, both functional and communication, which occur in existing IBD m-Health and e-Health systems, and introduces two topics – communication and design studies – in the "User Innovator" model of Von Hippel (1976) which consists of users, that are, for example, patients with chronic diseases, and who innovate by creating solutions to solve personal problems because of unfavourable healthcare conditions. To validate in the design process the three perspectives – design, innovation and patient – were considered, and the framework “Human-social Interaction Model for e-Health Interfaces” was created, enabling a sustainable approach to research, with inputs from personal experience being used, introducing relevant feedback for the final goal of the preliminary studies, when creating the interface for mobile phone application particularly for Crohn’s disease, one of the IBD, with a new healthcare user experience. To reach the objective, a set of studies were conducted that were divided into two stages. The first, a literature review of the relationship between semiotics and interactive communication; the meaning of symbolic representation in interactive projects; new design research guidelines that define interfaces and features and that are more approachable for users; user perspectives towards technology for health supporting and controlling; the design and communication space on technological projects; the challenge for users/ patients who try to create systems to solve personal problems. The second part, presents the practical research that includes a survey of 279 participants with IBD; the empirical analysis of six case studies – mobile applications and multiplatform: context, features, design principles lifting, and usability testing A/B with the design features and principles of design on two of the six systems being compared. The results from the thesis challenge the concepts of mobile interface usability in health, providing users with a structured interpretation of medical information design and a guideline for designers with chronic diseases that would like to create solutions to monitor health problems.Reduzir a institucionalização hospitalar de cidadãos com doenças crónicas é uma das prioridades para os países ocidentais. Quanto maior for a complexidade das condições de saúde, mais difícil se torna a coordenação dos cuidados clínicos. Para melhorar o controle e a gestão da doença, a maioria destes pacientes recorre às aplicações para telemóvel disponíveis em lojas online e aos serviços na web pois, é difícil obter permissão para aceder a dados clínicos em tempo real no telemóvel pessoal a partir do hospital. No contexto da DII – Doença Inflamatória do Intestino – as soluções existentes apresentam níveis de complexidade visual elevados pois, a interface comunica com o utilizador através de símbolos clínicos inadequados em funcionalidades convencionais – fraca legibilidade e inconsistência; Apresenta também, fraca coerência visual entre sistemas multiplataforma. Estes cenários promovem no utilizador, um aumento da curva de aprendizagem relativamente à forma como estes interagem com os sistemas criando assim, uma abertura para o desenvolvimento de soluções pelos que têm habilidade para inovar através da criação e desenvolvimento de sistemas que resolvem os seus problemas com a gestão e coordenação da doença. Esta tese tem como objetivo analisar o comportamento dos pacientes com DII relativamente à gestão da sua doença. Identificar que tipo de problemas – funcionais e de comunicação – existem nas soluções atuais para telemóvel e web no contexto da DII, introduzindo novos temas – estudos em comunicação e design – no modelo "User Innovator" de Von Hippel (1976) que consiste em, utilizadores, como por exemplo, pacientes com doenças crónicas, que inovam ao criarem soluções para resolver os problemas pessoais, tais como, condições de saúde adversas. Para validar no processo de design a integração das três áreas – design, inovação e paciente – criamos a framework “Human-social Interaction Model for e-Health Interfaces” que nos permitiu uma abordagem sustentável à investigação, quando foram aplicados inputs provenientes de experiência pessoal das três perspectivas introduzindo feedback relevante para o objetivo final dos estudos preliminares, também quando criada a interface para dispositivos móveis focada na doença de Crohn, uma das DII, com uma nova experiência de utilizador na área da saúde. Para atingir o objectivo, realizou-se um conjunto de estudos que se encontram divididos em dois momentos: o primeiro, com revisão de literatura sobre a relação da semiótica com a comunicação interativa; o significado da representação simbólica em projetos interativos; as novas linhas de reflexão do Design que definem interfaces e funcionalidades mais próximas do utilizador; a perspectiva dos utilizadores perante a tecnologia como meio de suporte e controle da saúde; o espaço do design e da comunicação em projetos tecnológicos; o desafio para utilizadores/ pacientes que tentam criar sistemas para solucionar problemas pessoais. A segunda parte apresenta a investigação de campo com, um inquérito a 279 participantes com DII; análise empírica de seis casos de estudo – aplicações para telemóvel e multiplataforma: contexto, funcionalidades, levantamento de princípios do design, e testes de usabilidade A/B onde comparamos em dois dos seis sistemas, a articulação entre as funcionalidades e os princípios do design. Os resultados obtidos desafiam a usabilidade das interfaces para telemóvel no contexto da saúde, proporcionando aos utilizadores uma interpretação mais coerente do ponto de vista formal do design de informação médica e um caminho para designers com doenças crónicas que pretendem criar soluções para resolver problemas de monotorização da saúde

Navigating the sociocultural landscape in service design

This paper reports on a case study where a service design approach was implemented to develop strategies for scaling-up a social enterprise, building on design as a meaning-making and framing practice. Context deconstruction methods drawn from semiotics and cultural studies were introduced during user research. These methods facilitated exploration of global and local sociocultural trends, mapping business category themes and competing offers, and identifying potential user groups’ cultural codes – i.e. expectations, aspirations and socio-symbolic aspects of consumption that influence users’ value perception. Subsequently, insights translated into strategies and guidelines for reframing the service value proposition and touchpoints to appeal to a wider potential user range. Results indicate that widening exploration from a user- to a context-centred approach enhances designers’ strategic skills, building stronger capability to observe and interpret sociocultural needs and attitudes. In turn, this highlights the central role of the service designer in leveraging the acceptance and diffusion of innovations
