Designing Attention-Centric Notification Systems: Five HCI Challenges

Through an examination of the emerging domain of cognitive systems, with a focus on attention-centric cognitive systems used for notification, this document explores the human-computer interaction challenges that must be addressed for successful interface design. This document asserts that with compatible tools and methods, user notification requirements and interface usability can be abstracted, expressed, and compared with critical parameter ratings; that is, even novice designers can assess attention cost factors to determine target parameter levels for new system development. With a general understanding of the user tasks supported by the notification system, a designer can access the repository of design knowledge for appropriate information and interaction design techniques (e.g., use of color, audio features, animation, screen size, transition of states, etc), which have analytically and empirically derived ratings. Furthermore, usability evaluation methods, provided to designers as part of the integrated system, are adaptable to specific combinations of targeted parameter levels. User testing results can be conveniently added back into the design knowledge repository and compared to target parameter levels to determine design success and build reusable HCI knowledge. This approach is discussed in greater detail as we describe five HCI challenges relating to cognitive system development: (1) convenient access to basic research and guidelines, (2) requirements engineering methods for notification interfaces, (3) better and more usable predictive modeling for pre-attentive and dual-task interfaces, (4) standard empirical evaluation procedures for notification systems, and (5) conceptual frameworks for organizing reusable design and software components. This document also describes our initial work toward building infrastructure to overcome these five challenges, focused on notification system development. We described LINK-UP, a design environment grounded on years of theory and method development within HCI, providing a mechanism to integrate interdisciplinary expertise from the cognitive systems research community. Claims allow convenient access to basic research and guidelines, while modules parallel a lifecycle development iteration and provide a process for requirements engineering guided by this basic research. The activities carried out through LINK-UP provide access to and interaction with reusable design components organized based on our framework. We think that this approach may provide the scientific basis necessary for exciting interdisciplinary advancement through many fields of design, with notification systems serving as an initial model. A version of this document will appear as chapter 3 in the book Cognitive Systems: Human Cognitive Models in Systems Design edited by Chris Forsythe, Michael Bernard, and Timothy Goldsmith resulting from a workshop led by the editors in summer 2003.

Ami-deu : un cadre sémantique pour des applications adaptables dans des environnements intelligents

Cette thèse vise à étendre l’utilisation de l'Internet des objets (IdO) en facilitant le développement d’applications par des personnes non experts en développement logiciel. La thèse propose une nouvelle approche pour augmenter la sémantique des applications d’IdO et l’implication des experts du domaine dans le développement d’applications sensibles au contexte. Notre approche permet de gérer le contexte changeant de l’environnement et de générer des applications qui s’exécutent dans plusieurs environnements intelligents pour fournir des actions requises dans divers contextes. Notre approche est mise en œuvre dans un cadriciel (AmI-DEU) qui inclut les composants pour le développement d’applications IdO. AmI-DEU intègre les services d’environnement, favorise l’interaction de l’utilisateur et fournit les moyens de représenter le domaine d’application, le profil de l’utilisateur et les intentions de l’utilisateur. Le cadriciel permet la définition d’applications IoT avec une intention d’activité autodécrite qui contient les connaissances requises pour réaliser l’activité. Ensuite, le cadriciel génère Intention as a Context (IaaC), qui comprend une intention d’activité autodécrite avec des connaissances colligées à évaluer pour une meilleure adaptation dans des environnements intelligents. La sémantique de l’AmI-DEU est basée sur celle du ContextAA (Context-Aware Agents) – une plateforme pour fournir une connaissance du contexte dans plusieurs environnements. Le cadriciel effectue une compilation des connaissances par des règles et l'appariement sémantique pour produire des applications IdO autonomes capables de s’exécuter en ContextAA. AmI- DEU inclut également un outil de développement visuel pour le développement et le déploiement rapide d'applications sur ContextAA. L'interface graphique d’AmI-DEU adopte la métaphore du flux avec des aides visuelles pour simplifier le développement d'applications en permettant des définitions de règles étape par étape. Dans le cadre de l’expérimentation, AmI-DEU comprend un banc d’essai pour le développement d’applications IdO. Les résultats expérimentaux montrent une optimisation sémantique potentielle des ressources pour les applications IoT dynamiques dans les maisons intelligentes et les villes intelligentes. Notre approche favorise l'adoption de la technologie pour améliorer le bienêtre et la qualité de vie des personnes. Cette thèse se termine par des orientations de recherche que le cadriciel AmI-DEU dévoile pour réaliser des environnements intelligents omniprésents fournissant des adaptations appropriées pour soutenir les intentions des personnes.Abstract: This thesis aims at expanding the use of the Internet of Things (IoT) by facilitating the development of applications by people who are not experts in software development. The thesis proposes a new approach to augment IoT applications’ semantics and domain expert involvement in context-aware application development. Our approach enables us to manage the changing environment context and generate applications that run in multiple smart environments to provide required actions in diverse settings. Our approach is implemented in a framework (AmI-DEU) that includes the components for IoT application development. AmI- DEU integrates environment services, promotes end-user interaction, and provides the means to represent the application domain, end-user profile, and end-user intentions. The framework enables the definition of IoT applications with a self-described activity intention that contains the required knowledge to achieve the activity. Then, the framework generates Intention as a Context (IaaC), which includes a self-described activity intention with compiled knowledge to be assessed for augmented adaptations in smart environments. AmI-DEU framework semantics adopts ContextAA (Context-Aware Agents) – a platform to provide context-awareness in multiple environments. The framework performs a knowledge compilation by rules and semantic matching to produce autonomic IoT applications to run in ContextAA. AmI-DEU also includes a visual tool for quick application development and deployment to ContextAA. The AmI-DEU GUI adopts the flow metaphor with visual aids to simplify developing applications by allowing step-by-step rule definitions. As part of the experimentation, AmI-DEU includes a testbed for IoT application development. Experimental results show a potential semantic optimization for dynamic IoT applications in smart homes and smart cities. Our approach promotes technology adoption to improve people’s well-being and quality of life. This thesis concludes with research directions that the AmI-DEU framework uncovers to achieve pervasive smart environments providing suitable adaptations to support people’s intentions

Study and proposal of a framework for designing tailorable user interfaces

Orientador: Maria Cecilia Calani BaranauskasTese (doutorado) - Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: A socialização dos sistemas computacionais trouxe um desafio a mais para os pesquisadores de Interação Humano-Computador: como prover interfaces que propiciem acesso ao maior número possível de usuários independentemente de suas capacidades sensoriais, físicas, cognitivas e emocionais? Um dos caminhos que se apresenta é desenvolver sistemas flexíveis, i.e. que permitam modificações em seu comportamento durante a interação, oferecendo ao usuário a possibilidade de ajustar a interface de acordo com as suas preferências, necessidades e situações de uso. O design de interfaces flexíveis, que façam sentido e sejam acessíveis a mais pessoas, demanda abordagens que permitam conhecer e formalizar os diferentes requisitos de interação, definir funcionalidades e determinar o comportamento ajustável do sistema. Soluções encontradas na literatura relacionadas ao tema interfaces ajustáveis, (ou tailoring em inglês) enfatizam questões relacionadas à infra-estrutura necessária para o ajuste, não tendo sido encontrados trabalhos que apoiassem os designers de forma prática durante o processo de concepção dessas interfaces. Esta tese propõe e apresenta um framework para o design de interfaces de usuário ajustáveis, denominado PLuRaL. O termo framework é utilizado aqui no seu sentido mais amplo como uma estrutura composta por diretrizes, mecanismos, artefatos e sistemas usados no planejamento e na tomada de decisões de design. O PLuRaL adota uma perspectiva sócio-técnica para a concepção das interfaces ajustáveis e uma visão abrangente dos requisitos de interação, incluindo aqueles que são controversos ou minoritários e advindos não somente de usuários, mas também de diferentes dispositivos e ambientes de interação. Aspectos semânticos, pragmáticos e o impacto social da interação também são considerados. Por fim, o comportamento ajustável do sistema é modelado utilizando-se o conceito de normas. O referencial teórico-metodológico adotado para o trabalho de pesquisa envolveu as disciplinas de Interação Humano-Computador e Semiótica Organizacional. A construção do framework foi pautada por 2 estudos de caso envolvendo populações de usuário heterogêneas em contextos de sistemas de governo eletrônico e de rede social inclusiva. A validação do framework foi realizada com 17 designers e os resultados sugerem uma avaliação positiva considerando a utilidade, flexibilidade para apoiar mudanças, liberdade de criação e satisfação com as propostas de design resultantesAbstract: The socialization of computer systems has brought a new challenge to Human-Computer Interaction researchers: how to design interfaces that provide access to as many users as possible regardless of their sensory, physical, cognitive and emotional characteristics? One approach to answer this question is to develop flexible systems, i.e. those that allow changes in their behavior during the interaction, offering users the possibility to tailor the interface according to their preferences, needs and situations of use. The design of flexible interfaces, which make sense and are accessible to more people, demands approaches to understand and formalize the different interaction requirements, define functionalities and determine the system tailorable behavior. Solutions found in the literature about tailorable interfaces have focused on the infrastructure needed to offer flexibility and works to support designers in a practical way during the conception of such interfaces were not found. This thesis proposes and presents a framework for the design of tailorable user interfaces, named PLuRaL. The term framework is used here in its broadest sense as a structure consisting of guidelines, mechanisms, artifacts and systems used in design planning and decision-making. PLuRaL adopts a socio-technical approach to design tailorable interfaces and a comprehensive view for interaction requirements, including those that are controversial or from minority, and arising not only from users, but also from different devices and interaction environments. The semantic, pragmatic and social impacts of the interaction are also considered. Finally, the behavior of the tailorable system is modeled using the concept of norms. The theoretical and methodological references adopted in this work involved the disciplines of Human-Computer Interaction and Organizational Semiotics. The framework's construction was guided by 2 case studies with heterogeneous populations, in the context of electronic government and inclusive social network system. The framework's validation was performed with 17 designers and the results suggest a positive evaluation considering the usefulness and flexibility to support changes, freedom to create and satisfaction with the final design proposalsDoutoradoMetodologia e Tecnicas da ComputaçãoDoutor em Ciência da Computaçã

Co-designing a chatbot for and with refugees and migrants

An information portal, HandbookGermany.de, is developed to support the integration of refugees and migrants into society in Germany. However, the information-seeking process is exhausting, cumbersome, and even confusing if refugees and migrants are not proficient at using web services. In light of this, a chatbot-based conversational service is considered as an alternative to enhance the information-seeking experience. For the purpose of designing products and services for refugees and migrants, a great deal of research proposes employing co-design methods as an effective means. The overall aim of this thesis is to explore, understand, and define possibilities of improving refugees and migrants’ experiences of social integration by proposing an engaging and efficient chatbot solution. Furthermore, this thesis aims to explore the necessity of co-design approach as a critical methodology to develop solutions. Therefore, the main research question in this thesis is how can a co-design approach contribute to designing a chatbot supporting social integration within the context of refugees and migrants. User experience, problems, and needs are unveiled in depth by listening to migrants and refugees’ problems, behaviors, and expectations (i.e., document studies, questionnaires, cultural probes, and expert interviews), and observing how migrants interact with the chatbot (i.e., participant observations and empathy probes). The research findings are then transformed into design questions. The designer, developers, and migrants jointly generate concepts leveraging generative toolkits in co-design workshops. By using surveys, the Method for the Assessment of eXperience (MAX), and property checklists, the resulting concepts are later validated with refugees and migrants. As research through design, this thesis draws three conclusions. Firstly, the co-design approach benefits defining problems in the complex context of refugees and migrants by supporting them in expressing ideas and thoughts. The defined problems can then be converted into design questions that promote the proceeding of the design process. Secondly, the co-design approach helps to develop mature concepts, which lays a foundation for the final design. Thirdly, the utilization of co-design tools plays an essential role in validating and refining the solution efficiently, as they make ideas concrete and visible so that refugees and migrants can easily reflect on them throughout the whole design process

Community participatory design in the information systems development process in Africa: a systemic literature review

Participatory design (PO) pertains to the different ways of incorporating ideas and acts of organisational members in designing, developing and evaluating an Information Systems (IS) artefact. The context of this study is community organisations in African settings participating in the designing and developing of an IS artefact. The study traces and synthesises findings from 95 articles on community PO in Information Systems Development in Africa. It argues that community PO consists of vast diverse constructs and implementations. This produced and reproduced concept is formulated in five major themes of: conceptualisations; ethics; standards; checks and balances and approaches; and perspectives and methodologies of PD. The themes constitute the possible ways of classifying PO research and practice in African settings. The results demonstrate that there is a wide belief that participation is one of the vital ingredients necessary for successful designing of IS artefacts for human development. However, the different elements involved in PO involve much discussion on what is known and needs to be known about PO and how to achieve the desired results by PD. The study uses Critical Research philosophy to pay special attention to the behavioural and attitudinal arguments of the different PO practices on community organisations. The researcher found Design Science (OS) principles that centre on devising an artefact as appropriate to frame this work. In sum, through the use of Critical Research and a OS lens, the researcher found that community participation is important in designing a useful IS artefact, but treacherous if misunderstood and inappropriately implemented

Design da interação na Web pragmática : reduzindo barreiras semióticas na colaboração mediada pela Web

Orientador: Maria Cecília Calani BaranauskasTese (doutorado) - Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: Web e suas tecnologias de base facilitam interações entre pessoas que alguns anos atrás não eram imagináveis. A colaboração é um tipo importante de interação que tem um propósito. Pessoas de diferentes contextos sociais e culturais, e com diferentes preferências e habilidades, podem colaborar mediadas pela Web. A colaboração muitas vezes acontece em contextos heterogêneos, que são definidos tanto pelas situações atuais dos parceiros na colaboração, quanto pelas experiências passadas, sejam elas individuais ou coletivas. A Web como um meio/uma mídia tem um impacto na colaboração e facilita certos aspectos da colaboração enquanto dificulta outros. Adotando uma perspectiva informada pela Web Pragmática, nesta tese investigamos questões da colaboração mediada pela Web, relacionadas com o Design da Interação. Nosso objetivo principal é entender barreiras semióticas da colaboração mediada pela Web e propor uma abordagem ao Design da Interação que reduza tais barreiras. Barreiras semióticas são barreiras relacionadas à comunicação, mediação e representação. Estas barreiras surgem na colaboração mediada pela Web pois muitos mecanismos da comunicação interpessoal face-a-face não estão disponíveis. Dependendo do contexto, barreiras semióticas frequentemente exercem um impacto negativo à colaboração; entretanto, em alguns casos o impacto pode ser positivo também. A abordagem ao Design da Interação aqui proposta tem suas bases na Web Pragmática e utiliza a Semiótica Organizacional e a Teoria da Atividade como referenciais teórico-metodológicos. As investigações teóricas contaram com uma contrapartida em termos de um embasamento em práticas reais através da participação em um projeto de pesquisa no domínio da educação inclusiva. Materializamos a abordagem proposta no design de um protótipo e na implementação de uma ferramenta correspondente ao protótipo, que apoia uma prática de profissionais no domínio da educação inclusiva. Além disso, propusemos e conduzimos um método de avaliação guiada pela pragmática dentro do contexto de um estudo de caso longitudinal. O design do protótipo, a implementação da ferramenta e a avaliação conduzida fornecem evidências de que a abordagem proposta ao Design da Interação guiada pela pragmática contribui para a redução de barreiras semióticas e para a promoção da colaboração mediada pela WebAbstract: The Web and its underlying technologies enable interactions among people that were unimaginable a few years ago. An important type of purposeful interaction is collaboration. Mediated by the Web, people from different social and cultural backgrounds, with different needs, preferences and capabilities can collaborate with each other. Collaboration often takes place in heterogeneous contexts that are not only defined by the actual situations of the collaboration partners, but also by individual and collective past experiences. The Web as a medium has an impact on collaboration and facilitates or enables certain aspects of collaboration while making others more difficult. In this PhD thesis we investigate Interaction Design related questions about web-mediated collaboration under a Pragmatic Web perspective. Our prime objective is to understand semiotic barriers to web-mediated collaboration and propose an approach to Interaction Design that reduces these barriers. Semiotic barriers are barriers related to communication, mediation and representation. These barriers emerge during web-based collaboration since many mechanisms of interpersonal face-to-face communication are not available. Depending on the context, semiotic barriers often have a negative impact on collaboration, but in some cases they might also have positive effects. The approach to Interaction Design proposed in this PhD thesis is rooted in the Pragmatic Web and uses Organizational Semiotics and Activity Theory as its theoretical and methodological frames of reference. The theoretic investigations were practically grounded in real world practices by participating in a research project in the domain of inclusive education. We materialized the proposed approach in the design of a prototype and the implementation of the corresponding tool that supports a practice of inclusive education professionals. Furthermore we proposed and applied a pragmatics-driven evaluation method in a longitudinal case study. Prototype design, tool implementation, and the conducted evaluation provided evidence that the proposed approach to pragmatics-driven Interaction Design can reduce semiotic barriers and thus promote web-mediated collaborationDoutoradoCiência da ComputaçãoDoutor em Ciência da Computaçã
