Desafios de design para a TV digital interativa BIBAFull-Text 1-10
  Lara Schibelsky Godoy Piccolo; Maria Cecília C. Baranauskas
Taking in account the social relevance of the terrestrial TV in Brazil and the transition to the digital technology -- meaning new opportunities for exploring interactivity on TV -- this paper is a worldwide review of HCI studies applied to interactive TV. Organizational semiotics artifacts are used in order to identify the main questions related to the interactive TV in the Brazil scene. The main design challenges are also pointed out by this study.
Design para a inclusão: desafios e proposta BIBAFull-Text 11-20
  Amanda Meincke Melo; M. Cecília C. Baranauskas
Although Web Standards, guidelines, checklists, techniques, methods and tools have been proposed and evaluated by the academic community and practitioners to improve Web accessibility and usability, efforts are still necessary to fit all those design artifacts in a design framework that deeply considers the multiplicity and diversity of users. This work presents the concepts and challenges of design for inclusion and combines contributions coming from some disciplines, especially Human-Computer Interaction, Organizational Semiotics and Software Engineering, to address the challenges that the users' differences bring to the process of constructing web-based systems applications and their interfaces. A process model for the inclusive design of information systems in the Web is delineated.
BuscaSigno: a construção de uma interface computacional para o acesso ao léxico da língua de sinais Brasileira BIBAFull-Text 21-30
  Marcelo Duduchi; Fernando Cesar Capovilla
The paper describes SignRetrieval, a computerized system with a graphic-interface that allows deaf and hearing users to retrieve thousands of Brazilian sign language signs without depending on the knowledge of the Portuguese gloss that corresponds to the sign. It describes how the system was built and how it can be used to effectively retrieve Libras signs. It also describes the sign retrieving behavior of a user, thus shedding light upon strategies to use the system as a resource for the continuous expansion of the sign lexicon.
Desenvolvimento de interfaces multimodais a partir da integração de comandos vocais à interface gráfica BIBAFull-Text 31-39
  Claudia P. P. Sena; Celso A. S. Santos
In the last years, mouse/keyboard based graphical interaction is the current standard of human-computer interfaces. The integration of voice as an input mode to visual-only interfaces provide means for reducing some of the known limitations of existing human-computer interaction. One of the major issues that remains is how to integrate voice input into a graphical interface application. In this paper, we introduce a process for developing multimodal interfaces that combine voice and visual input/output. In order to evaluate the proposed approach, a video application multimodal interface was implemented and analysed.
Caracterizando desafios de interação com sistemas de mineração de regras de associação BIBAFull-Text 40-49
  Elisa Tuler; Raquel O. Prates; Fernando Almir; Leonardo Rocha; Wagner, Jr. Meira
Data mining focuses on extracting useful information from great volumes of data, and thus has been the center of great attention in the recent years. Among the many techniques available for data mining, identifying association rules is one of the most popular. The novel aspect of rule association mining systems brings new challenges to the HCI field. In this article, we identify these challenges and analyze them based on the theory of action, and characterize it within the semiotic engineering theoretical framework. Thus, we provide designers with an explanation of aspects to be considered during use and design of such systems. This theoretical based explanation contributes to a deeper understanding of the issues involved in interacting with association rules mining systems, allowing for better informed decisions during design process. It also motivates future empirical investigations.

Short papers

Applying common sense to distance learning: the case of home care education BIBAFull-Text 1-4
  Junia Coutinho Anacleto; Aparecido Fabiano P. de Carvalho; Vânia Paula de Almeida Néris; Muriel de Souza Godoi; Silvia Zem-Mascarenhas; Américo Talarico Neto; Henry Lieberman
One of the challenges of Distance Learning (DL) over the Web is that it imposes physical distance between teachers and students, and thus reduces opportunities for teachers to fully understand the state of student knowledge and adapt instructional material to their needs. While the knowledge to be taught is usually well expressed in the curriculum material, the knowledge of a typical student is harder to codify. In this paper, it is shown how a large knowledge base of common sense statements can be used to help model student knowledge and consequently to help teachers plan learning actions by
  • Identifying topics that need coverage by the curriculum;
  • Identifying what a student is already likely to know;
  • Locating possible misconceptions that need to be corrected; and
  • Assuring that the student understands the vocabulary needed to express
       relevant subject material.
  • Customization of sensor-based input devices BIBAFull-Text 5-8
      Felipe S. Santos; Maria Graça Pimentel; Cesar A. C. Teixeira
    The literature reports many efforts with respect to facilitate building applications using non-traditional input devices -- for instance to support those designers who do not master the low level programming demanded for building sensor-based applications.
       We present an architectural approach to support the flexible customization of sensor-based input devices so as to provide a systematic procedure to personalize input devices.
    Desafios para testes de usuários em sistemas colaborativos -- lições de um estudo de caso BIBAFull-Text 9-12
      Raquel Oliveira Prates; Alberto Barbosa Raposo
    Collaborative systems evaluation is still an open issue for researchers working on the fields of HCI and CSCW. In this paper we present the challenges experienced by evaluators in a real system evaluation. These challenges and the discussion about them contribute to the research in the field, as well as to the planning of evaluations involving users for collaborative systems.
    Design de interfaces tangíveis educacionais: uma metodologia baseada em contexto BIBAFull-Text 13-16
      Taciana Pontual Falcão; Alex Sandro Gomes
    Manipulatives are common tools in Mathematics classrooms of elementary school. Tangible interfaces aggregate the benefits of traditional manipulatives with the new forms of interaction provided by technology. This work proposes a methodology for the development of tangible interfaces for Mathematics teaching which would be suitable for Brazilian classrooms. To reach this aim, our design process is based on socio-culturalist principles and usability guidelines, placing the context-of-use analysis as a phase of utmost importance.
    Mapeamento de um portal de acesso de televisão digital em dispositivos móveis BIBAFull-Text 17-20
      Marília Mendes; Elizabeth Furtado
    This article describes about studies of Digital Television (DTV) and mobility. The advance and the dissemination of the mobile devices to access the DTV services occur quickly, so it is necessary to have a system to manage the content of these services in different platforms and to apply standards for the usability, in order to offer better accessibility to the users.
    Modelagem de tarefas para simulação do desempenho humano em erro BIBAFull-Text 21-24
      Lucia Vilela Leite Filgueiras; Lucas Vitti Rodrigues
    This paper presents a proposal of using CTTE -- Concurrent Task Tree environment as input to S. PERERE, a simulator of human performance in error. S.PERERE uses a cognitive architecture as its basis. The definition of human tasks in the syntax required by this architecture is prohibitively complicated for the intended user. CTTE can be used to make this task easier, provided some constraints are respected when defining human elementary behaviors.
    O diálogo como metáfora dos processos de desenvolvimento de software BIBAFull-Text 25-28
      Flávia Peres; Luciano Meira
    This article presents a theoretical argument and a short observational study in favor of a new metaphor for IHC studies about the processes involved in software development: dialogism. Based on the written production of the Bakhtin Circle as well as on a socio-cultural perspective of cognition as "situated" and "distributed", we discuss the dialogical nature of software development as a process, from the initial moments of authoring to the later stages of its use. In the same vain, we advance design directions aimed at enhancing machine responsiveness in human-machine communication. Finally, we briefly report an ongoing ethnographical and videographical study of designers' and engineers' activities in a simulated "software house", and the activities that "final" users engaged in with the artifacts thus produced.
    O papel comum como interface para TV digital BIBAFull-Text 29-32
      Fábio de Jesus Lima Gomes; José Valdeni de Lima; Rosane Aragon de Nevado
    This paper considers the use of a barcode reader as Digital TV (DTV) interaction device. With the DTV, t-learning arises as an opportunity in order to promote the learning to a major amount of people than the traditional e-learning doesn't reach. But, the use of remote control in the DTV has resulted a complex viewer interaction that may cause the user's frustration and irritation and the ease of use is one of the most important factors in the DTV. This paper aims linking the common paper with DTV, in order to get better usability and promote more conditions to t-learning. Moreover, this paper also considers a card, a keyboard and commercial product catalogue, using the same technology.
    Percorrendo o processo de identificação da oportunidade dentro do Framework para a IHC centrada em valores BIBAFull-Text 33-36
      Cristian Cechinel; André Longhi; Daniela Bernardi
    This paper presents a brief report about the first attempts to develop websites for two computing courses of the Universidade do Oeste de Santa Catarina -- Campus de São Miguel do Oeste, using the Value-Centred HCI Framework proposed by Gilbert Cockton. On this very beginning, the research has used the first framework process called Opportunity Identification. The methodology to develop this work consisted of: 1) Interviewing and observing students from computing courses while using the Internet and the current computing courses websites, and 2) Applying a Content Analysis on the compiled interview reports. At last, 6 (six) values were identified and selected to be used on the next websites development stages.

      Waldemar P. F. Neto; Ana Esther V. Barbosa; Lucas A. de Lima; Joseana M. Fechine
    The PERSEU aims to join the Information Technology and Physical Therapy at the fight against the RSI. At the first stage of the project, a survey and an evaluation of the clinical state related to RSI was done using the professors and students from UFCG. At the next stage, the RSI prevention tool was planned according to the results of the previous stage, the mains functionalities identified were implemented, and, currently, the software is in conclusion stage. The main contribution of the project consists in the development of a computational tool which aims to provide a prophylaxis to RSI, characterizing itself for been a strongly interdisciplinary research.
    Reuso de interfaces através de padrões concretos de interação BIBAFull-Text 41-44
      Augusto Abelin Moreira; Marcelo Soares Pimenta
    The goal of this paper is to introduce an approach to user interface (UI) reuse by means of concrete interaction patterns (CIPs) usage. A CIP extends the usual interaction pattern documentation describing interactions and user interface behaviour through User Interface Description Language (UIDL), allowing reuse and implementation of an abstract user interface to different platforms and technologies.
    Uma proposta de institucionalização da usabilidade alinhada com práticas do modelo CMMI e foco nas necessidades da organização BIBAFull-Text 45-48
      David Falcão Barbosa; Elizabeth S. Furtado; Albert Schilling Gomes
    This paper presents a proposal to perform usability institutionalization in software development organizations, focusing on the association of existing practices in the field of Human Computer Interaction (HCI) with CMMI practices and organization needs. In this work, we intend to demonstrate (to usability professionals), that usability practices can be associated with some existing organizational practices, in an appropriate and collaborative manner. We also intend to demonstrate (this time, to the whole organization), that these practices can help to improve the quality of their products and, consequently, the maturity of the development process of the organization.

      Janne Y. Y. Oeiras; Fernanda M. P. Freire; Ricardo Luís Lachi; Heloísa V. da Rocha
    This paper presents the process of developing a new design to the chat tool of TelEduc environment in order to support collaborative activities in distance courses. This process arouse from the analysis of the tasks that will be carried out by the users from the point of view of the language action. Besides that, coordination mechanisms were added to the tool in order to put into practice the different tasks that should be accomplished, and the results of the tests show improvements in the organization of a conversation.
    Conveying mood and emotion in instant messaging by using a two-dimensional model for affective states BIBAFull-Text 66-72
      J. Alfredo Sánchez; Norma P. Hernández; Julio C. Penagos; Yulia Ostróvskaya
    We discuss the development and initial experiences with an instant messaging (IM) system that has been enhanced with functionality that facilitates the expression of affective states. This functionality is based on: (1) the use of a graphical, two-dimensional base model developed by psychology researchers; (2) refinements of the base model to allow for increased precision in the expression of affective states while exchanging messages; and (3) the definition of meaningful icons associated with the aforementioned model. Experiments have been conducted which show that users are able to take advantage of the proposed IM enhancements when trying to convey affect.
    Evaluating the impact of different virtual characters in product recommendations BIBAFull-Text 73-80
      Eliseo Reategui; Cristiano Fruet; Danilo Marcondes Filho
    This paper presents an evaluation of the effect that distinct interface characters could have on the users' perception of their interaction with an ecommerce website. A recommender system has been integrated to the characters' architecture, with the goal of assessing their impact in making personalized recommendations. The characters used to interact with the users had different features such as being a known or an unknown person; being represented by an anthropomorphic figure or not. In spite of these differences, the characters also had a lot of similarities: they used the same language and had the same strategy for recommending products. They also had the same type of graphical representation. An experiment involving 180 students was set up, in which students had to complete a few purchases in an ecommerce website where the virtual characters gave tips and suggested products related to the users' perceived interests. The results of the experiment are presented here, as well as conclusions and direction for future work.
    Animações através de programação por demonstração BIBAFull-Text 81-90
      Débora Pereira Coura; Vladimir Oliveira Di lorio; Alex Guimarães Lima; Alcione P. Oliveira; Marcus Vinícius A. Andrade
    Programming by demonstration (PBD) is a technique for teaching the computer new behavior by demonstrating actions on concrete examples. This technique is intensely applied in systems for the creation of animated simulation, in order to make their interface more intuitive. This work proposes three improvements for animated simulation tools based on programming by demonstration: first person perspective for rules, use of inheritance and rules with negative conditions. The improvements suggested are implemented in a new system developed by the authors. The new system is compared with the most important similar tools, showing the benefits provided by the techniques proposed.

    Methods and approaches do HCI design

    Applying a multi-criteria approach for the selection of usability patterns in the development of DTV applications BIBAFull-Text 91-100
      Kenia Sousa; Hildeberto Mendonça; Elizabeth Furtado
    In this paper we describe a multi-criteria approach in which the execution of its steps integrated to a Software Development Process (SDP) allow the generation of the User Interface (UI) Definition Plan, which is an artifact used for UI design of software. This approach applies techniques from Operational Research (OR), and from Human-Computer Interaction (HCI), considering diverse criteria (functional and non functional requirements) that have an impact on the interaction design and using usability patterns, respectively. In this text, its main goal was to identify the order of attractiveness of a list of usability patterns for a certain interactive task of Digital TV (DTV) applications, thus allowing the selection of the most appropriate pattern in this new communication resource.
    Extreme designing: binding sketching to an interaction model in a streamlined HCI design approach BIBAFull-Text 101-109
      Bruno Santana da Silva; Viviane Cristina Oliveira Aureliano; Simone Diniz Junqueira Barbosa
    This paper presents a streamlined approach to human-computer interaction design called extreme designing. Extreme designing follows on the footsteps of agile methods and is analogous to extreme programming. However, it is not radically committed to "user interface coding" (sketching or prototyping alone), but instead proposes to combine user interface sketches with a more structured representation such as an interaction model. By doing so, it brings together the advantages of sketching and prototyping as a communication tool, and of interaction modeling as a glue that binds together the sketches to allow designers to gain a more comprehensive view of and to reflection on the interactive artifact, thus promoting a more coherent and consistent set of design decisions.
    Contribuições da MoLIC para a reflexão sobre o conteúdo do sistema de ajuda BIBAFull-Text 110-119
      Otávio A Martins Netto; Milene Selbach Silveira; Simone Diniz Junqueira Barbosa
    Despite the efforts to improve HCI issues, the users still find problems when interacting with applications. This naturally demands the need for help systems. But the construction of such systems depends on the availability of information (and the necessary reflections upon them) to compose its contents. This work investigates if the MoLIC language can contribute to the construction of help systems by checking the design reflections that this language leads a designer to exercise.
    Human error simulation as an aid to HCI design for critical systems BIBAFull-Text 120-127
      Luiz Carlos Begosso; Lucia Vilela Leite Filgueiras
    Human errors are understood as a combination of many factors. Among them are the limitations of human information processing and the difficult matching of automation and human abilities. In the conception of HCI for critical systems, the ability to identify possible human errors and their consequences is fundamental for designing defenses for these errors. However, the myriad of forms that human error can assume may distract the designer from this task. This paper describes S. PERERE (Simulation of Performance in Error), a human erroneous behavior computational simulator and its prospective usage as an aid to critical systems' HCI design. S. PERERE is based on ACT-R (Atomic Components of Thought -- Rational) cognitive architecture.
    Usando a IMML no desenvolvimento de interfaces de usuário para múltiplas plataformas BIBAFull-Text 128-137
      Macilon Araújo Costa Neto; Jair Cavalcanti Leite
    This work presents a proposal to cross-platform user interface development, stating the main problems faced by designers for achieving this task. The solution suggested by this approach consists of using the model-based development approach, supported by IMML (Interactive Message Modeling Language), an interface description language that was grounded on Semiotics Engineering theory. We propose rules to make the mapping among IMML models possible. We also present rules to map from the model to concrete user interface in different models.
    Using IMML and XICL components to develop multi-device web-based user interfaces BIBAFull-Text 138-147
      Lirisnei Gomes de Sousa; Jair Cavalcanti Leite
    Multi-device development is an important issue in current user interface development. In this work, we present a solution to multi-device user interface development that combines two languages. One language is XICL, a markup language to describe user interfaces and UI components. The other is IMML (Interactive Message Modeling Language), a user interface description language. IMML allows a model-based specification separating the functional, interaction and communication aspects of an interactive system. We develop a software tool that translates from an IMML specification to DHTML, using XICL as an intermediary language. Currently, our solution is limited to browser-based software.

    Evaluating aspects of the user experience

    The semiotic inspection method BIBAFull-Text 148-157
      Clarisse Sieckenius de Souza; Carla Faria Leitão; Raquel Oliveira Prates; Elton José da Silva
    This paper describes semiotic inspection, a semiotic engineering evaluation method. It briefly identifies the essence of theory-based evaluation methods in HCI. Then it provides a detailed description and illustration of this method, which is based on a semiotic theory of HCI. It discusses its theoretical stance in semiotic engineering compared to the communicability evaluation method, as well as the perceived advantages and disadvantages of semiotic inspection. Finally, it points at the next steps in the semiotic inspection research agenda.
    Comparação entre os métodos de avaliação de base cognitiva e semiótica BIBAFull-Text 158-167
      Luciana Cardoso de Castro Salgado; Sílvia Amélia Bim; Clarisse Sieckenius de Souza
    In this article we present a comparative study of three methods: Cognitive Walkthrough, Heuristic Evaluation, and Communicability Evaluation. The aim of the study is to compare costs and benefits of the three, so as to inform decisions about which one to choose when time and feedback for (re)design are the most critical factors. The study was carried out as an academic exercise by graduate students in HCI. Results suggest that, of the three methods, Communicability Evaluation produces the most informative results, whereas Heuristic Evaluation is the most cost-effective.
    Um framework para avaliação de interfaces de aplicações SIG web BIBAFull-Text 168-177
      Juliano Schimiguel; M. Cecília C. Baranauskas; Claudia Bauzer Medeiros
    User Interfaces in Web applications of Geographic Information Systems (WebGIS) have been developed without the use of practices and criteria that consider characteristics of this application domain, given the diversity of users in the Web. The interface quality of these applications directly influences their use. This work proposes a semiotic-based framework for the evaluation of GIS applications' interfaces. A set of evaluation recomendations illustrates the framework usage in the GIS domain.
    Avaliação de ferramentas de busca na web baseadas em visualização de informaçães BIBAFull-Text 178-185
      Isabel Cristina Siqueira da Silva; Carla M. D. S. Freitas
    Web search engines are daily used with a variety of purposes. Usually, searches are submitted based on few terms and the results are dozens of links listed through several pages. Different criteria are used by the search engines to establish the order in which the links appear in this list. Often, the user has to browse the list until finding the relevant information. This scenario increases the need of alternative forms of displaying search results. Although internet services become more attractive when providing information through graphical representations, surprisingly very few initiatives have been devoted to the practical use of visual representations of search results. The present work addresses this issue by presenting a study about the experience and satisfaction of subjects when using two web search tools which display their results graphically. This study is a step towards the identification of requirements for visual tools
