CubIT : Large-scale multi-user presentation and collaboration

CubIT is a multi-user, large-scale presentation and collaboration framework installed at the Queensland University of Technology’s (QUT) Cube facility, an interactive facility made up 48 multi-touch screens and very large projected display screens. CubIT was built to make the Cube facility accessible to QUT’s academic and student population. The system allows users to upload, interact with and share media content on the Cube’s very large display surfaces. CubIT implements a unique combination of features including RFID authentication, content management through multiple interfaces, multi-user shared workspace support, drag and drop upload and sharing, dynamic state control between different parts of the system and execution and synchronisation of the system across multiple computing nodes.

Making sense of purpose, direction and innovation : an embedded design led innovation case study in the Australian mining industry

The mining equipment technology services sector is driven by a reactive and user-centered design approach, with a technological focus on incremental new product development. As Australia moves out of its sustained mining boom, companies need to rethink their strategic position, to become agile to stay relevant in an enigmatic market. This paper reports on the first five months on an embedded case study within an Australian, family-owned mining manufacturer. The first author is currently engaged in a longitudinal design led innovation project, as a catalyst to guide the company’s journey to design integration. The results find that design led innovation could act as a channel for highlighting and exploring company disconnections with the marketplace and offer a customer-centric catalyst for internal change. Data collected for this study is from 12 analysed semistructured interviews, a focus group and a reflective journal, over a five-month period. This paper explores limitations to design integration, and highlights opportunities to explore and leverage entrepreneurial characteristics to stay agile, broaden innovation and future-proof through the next commodity cycle in the mining industry.

Experience as meaning : some underlying concepts and implications for design

As the current computing systems move from desktop and work settings into our everyday lives (e.g. mobile and ubiquitous systems) a growing interest is seen for designing interactive systems with experiential support. Some conceptual work already exists that tries to analyze and understand users? experience with interactive systems but in practice this is still not frequently used. Drawing on the concepts from the domain of art, this paper introduces a way to conceptualize users? experience as the meanings or interpretations they construct during their interaction with or through the interactive systems. We consequently apply this conceptualization in a design project where we use it at an early concept design stage for designing aware technologies in care-taking situations.

Beyond Wearables : Experiences and Trends in Design of Portable Medical Devices

The use of Portable Medical Devices (PMDs) has become increasingly widespread over the last few years. A combination of factors; including advances in technology, the pressure to reduce public health costs and the desire to make health solutions accessible to a wider patient base are contributing to the growth in the PMD market. Design has a clear role to play in the current and future context of the PMD landscape. In this paper, we identify emerging trends in the design of PMDs; including changes in the form, purpose and mode of use, and explore how these trends are likely to fundamentally impact the nature of healthcare and the patient experience from an experience design perspective. We conclude by identifying a research opportunity for design within the healthcare and PMD context.

A lightweight, modular robotic vehicle for the sustainable intensification of agriculture

This paper describes a lightweight, modular and energy efficient robotic vehicle platform designed for broadacre agriculture - the Small Robotic Farm Vehicle (SRFV). The current trend in farming is towards increasingly large machines that optimise the individual farmer’s productivity. Instead, the SRFV is designed to promote the sustainable intensification of agriculture by allowing farmers to concentrate on more important farm management tasks. The robot has been designed with a user-centred approach which focuses the outcomes of the project on the needs of the key project stakeholders. In this way user and environmental considerations for broadacre farming have informed the vehicle platform configuration, locomotion, power requirements and chassis construction. The resultant design is a lightweight, modular four-wheeled differential steer vehicle incorporating custom twin in-hub electric drives with emergency brakes. The vehicle is designed for a balance between low soil impact, stability, energy efficiency and traction. The paper includes modelling of the robot’s dynamics during an emergency brake in order to determine the potential for tipping. The vehicle is powered by a selection of energy sources including rechargeable lithium batteries and petrol-electric generators.

Growing food in the city : Design ideations for urban residential gardeners

Urban agriculture refers to the production of food in urban and peri-urban spaces. It can contribute positively to health and food security of a city, while also reducing ‘food miles.’ It takes on many forms, from the large and organised community garden, to the small and discrete backyard or balcony. This study focuses on small-scale food production in the form of residential gardening for home or personal use. We explore opportunities to support people’s engagement in urban agriculture via human-computer interaction design. This research presents the findings and HCI design insights from our study of residential gardeners in Brisbane, Australia. By exploring their understanding of gardening practice with a human-centred design approach, we present six key themes, highlighting opportunities and challenges relating to available time and space; the process of learning and experimentation; and the role of existing online platforms to support gardening practice. Finally we discuss the overarching theme of shared knowledge, and how HCI could improve community engagement and gardening practice.

Fixing the alignment: An exploration of budgeting practices in the home

Budgeting is an important means of controlling ones finances and reducing debt. This paper outlines our work towards designing more user centred technology for individual and household budgeting. Based on an ethnographically informed study with 15 participants, we highlight a misalignment between people's actual budgeting practices and those supported by off-the-shelf budgeting aids. In addressing this misalignment we outline three tenets that may be incorporated into future work in this area. These include (1) catering for the different phases of engagement with technology; (2) catering for the practices of hiding and limiting access to money, and; (3) integrating materiality into technical solutions.

Preparing engineering graduates for the knowledge economy through blended delivery of mathematics

Contemporary higher education institutions are making significant efforts to develop cohesive, meaningful and effective learning experiences for Science, Technology, Engineering and Mathematics (STEM) curricula to prepare graduates for challenges in the modern knowledge economy, thus enhancing their employability (Carnevale et al, 2011). This can inspire innovative redesign of learning experiences embedded in technology-enhanced educational environments and the development of research-informed, pedagogically reliable strategies fostering interactions between various agents of the learning-teaching process. This paper reports on the results of a project aimed at enhancing students’ learning experiences by redesigning a large, first year mathematics unit for Engineering students at a large metropolitan public university. Within the project, the current study investigates the effectiveness of selected, technology-mediated pedagogical approaches used over three semesters. Grounded in user-centred instructional design, the pedagogical approaches explored the opportunities for learning created by designing an environment containing technological, social and educational affordances. A qualitative analysis of mixed-type questionnaires distributed to students indicated important inter-relations between participants’ frames of references of the learning-teaching process and stressed the importance (and difficulty) of creating appropriate functional context. Conclusions drawn from this study may inform instructional design for blended delivery of STEM-focused programs that endeavor to enhance students’ employability by educating work-ready graduates.

A happy compromise: Collaborative approaches to school library designing

Designing a school library is a complex, costly and demanding process with important educational and social implications for the whole school community. Drawing upon recent research, this paper presents contrasting snapshots of two school libraries to demonstrate the impacts of greater and lesser collaboration in the designing process. After a brief literature review, the paper outlines the research design (qualitative case study, involving collection and inductive thematic analysis of interview data and student drawings). The select findings highlight the varying experiences of each school’s teacher-librarian through the four designing phases of imagining, transitioning, experiencing and reimagining. Based on the study’s findings, the paper concludes that design outcomes are enhanced through collaboration between professional designers and key school stakeholders including teacher-librarians, teachers, principals and students. The findings and recommendations are of potential interest to teacher-librarians, school principals, education authorities, information professionals and library managers, to guide user-centred library planning and resourcing.

A generic design environment for the rural industry knowledge acquisition

This paper describes a new knowledge acquisition method using a generic design environment where context-sensitive knowledge is used to build specific DSS for rural business. Although standard knowledge acquisition methods have been applied in rural business applications, uptake remains low and familiar weaknesses such as obsolescence and brittleness apply. We describe a decision support system (DSS) building environment where contextual factors relevant to the end users are directly taken into consideration. This "end user enabled design environment" (EUEDE) engages both domain experts in creating an expert knowledge base and business operators/end users (such as farmers) in using this knowledge for building their specific DSS. We document the knowledge organisation for the problem domain, namely a dairy industry application. This development involved a case-study research approach used to explore dairy operational knowledge. In this system end users can tailor their decision-making requirements using their own judgement to build specific DSSs. In a specific end user's farming context, each specific DSS provides expert suggestions to assist farmers in improving their farming practice. The paper also shows the environment's generic capability.

Métodos e técnicas de Design Centrado no Usuário: um levantamento a partir da usabilidade de produtos do CTIC/Fiocruz

A relação causal entre métodos de projeto e a usabilidade de produtos de comunicação e informação foi o tema desse estudo que buscou identificar o estado da arte sobre um processo de projeto que resulte em mais usabilidade na web. A partir dessa identificação, avaliou-se as melhorias que poderiam ser adotadas nos processos de desenvolvimento de interfaces utilizados por uma equipe específica da Fundação Oswaldo Cruz (CTIC - Fiocruz). Entendeu-se que um método de projeto deve estar atualizado em relação aos conhecimentos de áreas como a Ergonomia, a Interação Humano-computador e o Design de Interação. Para isso, adotou-se a hipótese de que o processo de projeto deve combinar três aspectos: a) um significativo envolvimento do usuário ao longo do processo; b) o uso de sucessivas iterações para configurar o produto e c) uma combinação mínima de técnicas relacionadas a objetivos específicos de cada fase de uma abordagem de Design Centrado no Usuário. Para contribuir com o desenvolvimento de métodos e técnicas que melhorem a usabilidade, descreveu-se as características dos métodos registrados na literatura e praticados por profissionais externos à Fundação Oswaldo Cruz (Fiocruz). A partir dessas informações, o estudo direcionou-se para o segundo objetivo específico: identificar melhorias nos métodos e técnicas aplicáveis no caso do CTIC Fiocruz. Através da combinação da revisão de literatura e da pesquisa de campo foram produzidas informações sobre tipos de fluxo dos métodos, tipos de envolvimento dos usuários, quantidade e gravidade de problemas de usabilidade observadas pelos profissionais e a validade de base geral de método para diferentes produtos. A primeira rodada de entrevista foi realizada para melhor entender o contexto da hipótese e a relação entre suas variáveis. A segunda rodada identificou as características do processo de projeto utilizado no CTIC. A partir dessas informações, aplicou-se duas técnicas com profissionais externos. Um questionário on-line foi utilizado para levantar informações bem específicas, em sua maioria de características quantitativas. A última técnica aplicada foi um card sorting on-line que apresentou um caso de projeto em que os profissionais indicaram quais técnicas seriam utilizadas diante de dois cenários diferentes: um mais favorável e outro restritivo. A análise demonstrou que a maioria dos profissionais acredita que os problemas de usabilidade são consequência da falta de determinadas abordagens e técnicas. Por isso, esses profissionais combinam fluxos iterativos com um significativo envolvimento do usuário no processo. Foram sugeridas melhorias para o método utilizado no CTIC sintetizadas através de um processo de Design Centrado no Usuário como ponto de partida que aplica o conceito tradicional de usabilidade (performance). Assim que possível, esse processo deve ser aperfeiçoado ao incluir o conceito de experiência do usuário que considera também os aspectos emocionais e hedonômicos na interação.

Improvements in interface design through implicit modeling

Touchscreen devices are often limited by the complexity of their user interface design. In the past, iterative design processes using representative user groups to test prototypes were the standard method for increasing the inclusivity of a given design, but cognitive modeling has potential to be an alternative to rigorous user testing. However, these modeling approaches currently have many limitations, some of which are based on the assumptions made in translating a User Interface (UI) into a definition file that cognitive modeling frameworks can process. This paper discusses these issues and postulates potential approaches to improvements to the translation procedure. © 2013 Springer-Verlag Berlin Heidelberg.

Le design participatif au sein d’entreprises : une exploration des opportunités et limites perçues par des concepteurs de produits

La littérature contient une abondance d’information sur les approches de design impliquant les utilisateurs. Bien que les chercheurs soulèvent de nombreux avantages concernant ces approches, on en sait peu sur ce que les concepteurs des entreprises en pensent. Ce projet a pour but de connaître les perceptions des concepteurs de produits quant aux outils de design participatif puis, d’identifier les opportunités et limites qu’ils évoquent à ce sujet, et finalement, de faire des suggestions d’outils qui faciliteraient l’introduction du design participatif dans un processus de design existant. Après avoir fait un survol du domaine du design participatif et de ses outils, six cas sont étudiés au moyen d’entrevues semi-dirigées conduites auprès de concepteurs de produits. Les données sont analysées à l’aide de cartes cognitives. En ce qui concerne les outils de design participatif, les participants rencontrés perçoivent un accès direct aux besoins des utilisateurs et la possibilité de minimiser les erreurs en début de processus donc, d’éviter les modifications coûteuses qu’elles auraient entraînées. Les obstacles perçus par les concepteurs sont principalement liés à la résistance au changement, à la crainte de laisser créer ou décider les utilisateurs, ainsi qu’au manque de temps et de ressources de l’équipe. Finalement, sur la base des informations collectées, nous suggérons quatre outils de design participatif qui semblent plus intéressants : l’enquête contextuelle, les sondes, les tests de prototypes et l’approche « lead user ». Pour faire suite à ce travail, il serait intéressant d’élaborer un protocole de recherche plus exhaustif pour augmenter la portée des résultats, ou encore, d’appliquer le design participatif, dans une entreprise, afin d’explorer la satisfaction des gens quant aux produits conçus, les effets collatéraux sur les équipes impliquées, l’évolution des prototypes ou le déroulement des ateliers.

Élaboration de critères de design pour un outil de communication médecin-patient

Le système de santé d'aujourd'hui fait appel à de nombreuses technologies de l'information nommées TIS (Technologies de l’Information en Santé). Celles-ci ont donné naissance à de nouvelles formes d’interaction médecin-patient et ont complexifié l'approche thérapeutique dite
« centrée sur le patient ». Les TIS promettent une plus grande efficacité et l’augmentation de la satisfaction des patients par le biais d’une meilleure compréhension de la maladie pour le patient. Or, elles peuvent également devenir des sources de conflit pour le professionnel de la santé, étant donné leur utilisation en dehors des rencontres cliniques ainsi que leur tendance à agir comme des barrières communicationnelles lors des consultations. Cette recherche vise a étudier les critères de design nécessaires à la conception d’un TIS pouvant améliorer la relation médecin-patient et donc, faciliter la communication et améliorer l’alliance thérapeutique. L’étude utilise une approche centrée sur l’utilisateur et vise donc à comprendre les besoins et les attentes des médecins et des patients. En étudiant les nouvelles approches en santé et les TIS, il a été possible de comprendre le contexte et les besoins des utilisateurs en terme de communication. Ces derniers sont primordiaux au processus dit centré sur l’utilisateur. Le faible taux de rétention du discours du médecin devient une barrière communicationnelle importante, tout comme le temps pressurisé. La recherche nous montre que l’ajout d’un outil virtuel de vulgarisation peut, à l’aide de média visuels (tel que des modélisations, des animations 3D et des dessins), grandement aider la relation médecin-patient.

Rendre possible l’engagement en familiarité dans les CHSLD : les savoir-être d’une pratique de design centrée sur l’usager

Les défis associés au phénomène du vieillissement démographique de la population se manifestent sous plusieurs formes et à de nombreux égards. Il y a des questions générales comme celles qui touchent l’économique et d’autres, plus spécifiques et situées, comme celles des modalités assurant des services et des soins adéquats aux personnes vulnérables. Par exemple, le colloque « La qualité de l’expérience des usagers et des proches : vers la personnalisation des soins et des services sociaux », programmé dans le cadre des Entretiens Jacques Cartier à l’automne 2014, s’était donné comme objectif d’examiner l’expérience personnelle des usagers relativement aux prestations de soins de santé et à l’organisation des services sociaux. L’origine de ces réflexions réside dans la nécessité de trouver un meilleur équilibre des pouvoirs dans les relations d’aide ou la prestation de soin. Cette problématique sous-entend l’idée de rendre les usagers capables d’un certain contrôle par l’adoption d’approches permettant aux professionnels de faire des ajustements personnalisés. Cette thèse de doctorat s’inscrit directement dans le prolongement de cette problématique. La recherche vise à examiner les conditions en mesure de rendre possible, dans les Centres d’hébergement et de soins de longue durée (CHSLD), un rapport au monde catégorisé par ce que le sociologue Laurent Thévenot nomme le régime de la familiarité. Le régime de la familiarité fait référence aux réalités où l’engagement des personnes se déploie dans l’aisance. Autrement dit, ce régime d’engagement correspond à un rapport au milieu où la personne est en mesure de déployer ses habitudes, d’habiter le moment et de se sentir chez elle. Comme le montre Thévenot, ce type d’engagement commande la conception d’un monde qui offre aux personnes la possibilité d’articuler les modalités de leurs actions sur des repères qui font sens personnellement pour eux. Ainsi, l’objet de la recherche consiste à mieux comprendre la participation du design à la conception d’un milieu d’hébergement capable d’accueillir ce type d’engagement pragmatique. Les orientations associées à la conception de milieux d’hébergement capables de satisfaire de telles exigences correspondent largement aux ambitions qui accompagnent le développement des approches du design centrées sur l’usager, du design d’expériences et plus récemment du design empathique. Cela dit, malgré les efforts investis en ce sens, les capacités d’appropriation des usagers restent un problème pour lequel les réponses sont précaires. La thèse interroge ainsi le fait que les développements des approches de design, qui ont fait de l’expérience des usagers une préoccupation de premier plan, sont trop souvent restreints par des questions de méthodes et de procédures. Le développement de ces connaissances se serait fait au détriment de l’examen précis des savoir-être également nécessaires pour rendre les designers capables de prendre au sérieux les enjeux associés aux aspirations de ces approches. Plus spécifiquement, la recherche précise les qualités de l’expérience des établissements dont le design permet l’engagement en familiarité. L’enquête s’appuie sur une analyse des jugements posés par des équipes d’évaluation de la qualité du milieu de vie des CHSLD présents sur le territoire Montréalais. L’analyse a mené à la caractérisation de cinq qualités : l’accueillance, la convivialité, la flexibilité, la prévenance et la stabilité. Finalement, sous la forme d’un essai réflexif, un tableau de savoir-être est suggéré comme manière de rendre les designers capables de mettre en œuvre des milieux d’hébergement présentant les qualités identifiées. Cet essai est également l’occasion du développement d’un outil réflexif pour une pédagogie et une pratique vertueuse du design.
