Sobre aspectos da interação humano-computador para a web social BIBAFull-Text 1-2
  Adriana S. Vivacqua; José Viterbo; Sergio Roberto da Silva
A Web Social representa um novo paradigma no qual a Web deixou de ser um ambiente que interliga páginas e documentos para se tornar um ambiente que conecta pessoas, organizações e conceitos. Nesse contexto, a Web Social desempenha um papel central ao possibilitar que diversas pessoas interajam de formas e em escalas inéditas por meio de diferentes aplicações, construídas com diversas plataformas e embutidas em diferentes dispositivos. Atualmente, tablets, smartphones e outros dispositivos móveis, com seus recursos avançados -- tais como sensores, câmera, e interfaces de comunicação --, permitem o acesso e disseminação de informações de forma instantânea e contínua, possibilitando que a interação entre usuários aconteça ubiquamente, em situações e lugares onde antes não era possível. Informações sobre eventos específicos e momentâneos, que não seriam úteis depois de transcorrido um maior intervalo de tempo, passam a ser de suma importância quando compartilhadas em tempo real. Novas aplicações surgem a partir da possibilidade de registrar e compartilhar instantaneamente textos, imagens, sons, dados de localização e outras informações de interesse imediato. Entretanto, o uso de dispositivos móveis impõe desafios adicionais no que tange a questões relacionadas a adaptação de conteúdo para diferentes dispositivos, integração com aplicações tradicionais, interação entre usuários em movimento e o gerenciamento de informações de contexto dos usuários de forma a garantir a privacidade e segurança no compartilhamento ubíquo de dados. Desta forma, o foco da 4a edição do Workshop sobre Aspectos da Interação Humano-Computador para a Web Social (WAIHCWS'12) recai sobre o tema "Mobilidade e ubiquidade na Web Social -- desafios e oportunidades".

Challenges for users and designers in the design process of a satellite images handling system BIBAFull-Text 13-16
  Luciana A. S. Romani; Renata R. V. Gonçalves; Daniel Y. T. Chino; Agma J. M. Traina
In this paper, we present the design process of a system to support agrometeorologists to improve a tiresome task of extracting data to generate time series from multiple satellite images. To understand the difficulty of dealing with thousands of images, one researcher in HCI has worked in a team of agrometeorologists for over 6 months. This case study describes the experience of this researcher using a manual and semi-automatic method developed by agrometeorologists. Moreover, we highlight the difficulties faced by specialists trying to learn how to develop scripts in order to make their tasks easier. Finally, we report the involvement of these experts in the design process of a new system that led to a more successful approach to deal with the challenge of handling enormous amount of satellite images.

Interação entre time de design de interfaces e time de desenvolvimento: tentativas, fracassos e sucessos BIBAFull-Text 21-24
  Viviane Delvequio; Alessandra Rosa
O Mercado cada vez mais exige das empresas uma melhor experiência do usuário, que se reflete, dentre outros fatores, em softwares, sites, aplicativos com interface e interação fáceis e cativantes. Entretanto o mercado de desenvolvimento de software brasileiro passou muito tempo focando em outros fatores, também relevantes, mas imperceptíveis para esse público. Em contrapartida, agências de publicidade e marketing também passaram por uma mudança considerável em suas estratégias e serviços com o crescente uso e popularização da internet, redes sociais e dispositivos móveis. São dois mercados que foram igualmente impactados por essas mudanças e que têm muito a ensinar um ao outro. Neste case tratamos o que mudou em uma empresa de desenvolvimento de software para se adequar à essa nova realidade e receber no seu dia-a-dia essa massa de trabalho criativa, contando os desafios, fracasso e sucessos do processo de interação entre esses grupos.

Customizando heurísticas de usabilidade para celulares BIBAFull-Text 37-38
  Luiz Henrique A. Salazar; Thaísa Lacerda; Christiane Gresse von Wangenheim; Rodrigo Araújo Barbalho
Mobile phones have been the fastest growing segment of the technology market increasing the importance of interface design for this type of device. Yet, as many of the assumptions about user interactions that we know from "traditional" computer usage do not hold true for mobile devices, a key question is, if there exist specific usability heuristics for this type of device. To answer this question, we conduct a systematic literature review on usability heuristics for mobile (touch) phones and compare and map the identified heuristics. We also develop a checklist for heuristic evaluations based on the unified set of heuristics. The results are expected to contribute to the improvement of usability of cell phone applications considering their specific characteristics and limitations.

  Marcio Alexandre de Queiroz; Cecília Sosa Arias Peixoto
Studies show that the fraction of code devoted to user interface has been increasing and offering ever more efficient ways to exchange information between the user and the computer. In this context, the use of methods, techniques and tools that assist the designer during development is essential. This paper presents the SisBridge tool that besides generating the prototype user interface in the Web platform, suggests design guidelines for the modeling of the interface, which represents a contribution to The Bridge methodology. Additionally, the tool describes the contents and structure of interfaces for multiple devices using the UsiXML language (User Interface Extensible Markup Language).
An information visualization tool for data journalism BIBAFull-Text 41-42
  Ricardo Kramer de Oliveira Barros; Giuliano Araujo Bertoti
The current data overload makes it difficult to create journalistic texts. The large amount of data complicates the interpretation and its subsequent conversion into useful information due to the great effort required to understand it. The development of systems that simplify the data interpretation helps the authors to construct clearer and more objective stories, disseminating information and thus reaching a wider audience, enriching the debates regarding public issues. This paper aims to introduce to the reader a new concept of journalism, the data journalism, showing the importance on employing new information visualization tools in this model.

  Rodrigo Andrade; Adriana Vivacqua; Ana Cristina Bicharra Garcia
One of the challenges in medical emergency units is the efficient management of information and communication. When compared to other medical departments, the emergency department is one of the environments with greater information load. The increase in the amount of patients, lack of physical infrastructure to allocate patients, fewer physicians, increased complexity of patient treatment, extreme conditions, require of health agents a quick and efficient assimilation steady flow of information from the environment. This paper discusses the need for developing applications that are focused in the needs of health care providers on a domain of medical emergency, in order to support agents in patient care allowing optimization of the time spent in treatment and providing more information when discussing the clinical case and other forms of treatments.

Algoritmos de clusterização e python científico apoiando modelagem de usuário BIBAFull-Text 47-50
  Andrey Araujo Masiero; Leonardo A. Ferreira; Plinio Thomaz, Jr. Aquino
Python is a interactive, interpreted, object oriented, multi-plataform programming language with libraries that aid the studies in Human-Computer Interaction throughout the use of machine learning algorithms, that assists in the construction of the Personas user type. These might help the developer during the interface development and may also enhance the ones that are currently in use. The moment that this technique may apply depends on how the information is acquired -- with surveys or system's log. This paper presents an way to capture this information and transform this data, making possible to use clustering algorithms to group the collected profiles, enabling the automatization of the process in order to use in adaptive interfaces. Lastly, techniques grounded in statistics methods of spreadness measurements used to define a Personas and Python tools to graphically present the data, allowing an analytical comparison, will be demonstrated.
Sistematização de revisões bibliográficas em pesquisas da área de IHC BIBAFull-Text 51-54
  Elizabete Munzlinger; Fabricio Batista Narcizo; José Eustáquio Rangel de Queiroz
During the development of a scientific research in the field of Human-Computer Interaction (HCI) it is needful to identify, read, analyze and interpret relevant publications about a given theme or subject. Such a task usually results in large sets of bibliographical data. As a consequence, they must be put together in a single document, with the aim of making easy to assess the strength of the evidence of interest. Nonetheless, this is not an easy task to accomplish. Systematic reviews (SR) come to fulfill this need, by providing comprehensive, reliable, and unbiased summaries of a research on a single topic. Additionally, SR bring together large numbers of individual studies in a single report, provides the best evidence for decision making, and also help determine future research needs.
Projetando sistemas web com o uso de técnicas de interação humano-computador BIBAFull-Text 55-58
  Patricia Cristiane de Souza; Cristiano Maciel; Luciana A. O. de Moraes
It is fundamental to improve software development processes towards Web Engineering, which must consider, for example, the possibility of different types of users dealing with an application, as this would impact on the way people interact in the systems. [7] propose an agile framework, employing different methods for designing a web application (WebApp), which are represented in a pyramidal structure whose levels depict project actions. However, these actions are not integrated in Human-Computer Interaction (HCI) activities. Thus, this tutorial aims to enable participants to integrate HCI practices and Web Engineering methods by means of theoretical and practical strategies.
