Usabilidade: um fator crítico para da interatividade da televisão digital

Este artigo tem por objetivo fazer uma reflexão da usabilidade aplicada à interatividade do SBTVD (Sistema Brasileiro de Televisão Digital). Aborda as perspectivas de mercado no Brasil e na América Latina e cita alguns casos em que a usabilidade constituiu-se em fator decisivo para ampliar o ciclo de vida do produto. Explicita a interação e a engenharia de usabilidade com destaque para a garantia da consolidação da interatividade do SBTVD. Neste contexto, inclui o estabelecimento de redes de banda larga para todos, chamados de “cidade digital” condição decisiva no processo de possibilitar a democratização. Conclui que essa facilidade de usabilidade, aliada aos avanços tecnológicos digitais que propiciam uma qualidade e uma convergência tecnológica, que certamente romperá o modelo de telespectador passivo para um telespectador interativo gerando um novo contingente de telespectadores vindo da televisão digital e da televisão analógica.

Avaliação do Uso de Smartphones na Interação com as Aplicações da Televisão Digital Brasileira

Brazil is going through the process from analogical transmission to digital transmission. This new technology, in addition to providing a high quality audio and video, also allows applications to execute on television. Equipment called Set-Top Box are needed to allow the reception of this new signal and create the appropriate environment necessary to execute applications. At first, the only way to interact with these applications is given by remote control. However, the remote control has serious usability problems when used to interact with some types of applications. This research suggests a software resources implementation capable to create a environment that allows a smartphone to interact with applications. Besides this implementation, is performed a comparative study between use remote controle and smartphones to interact with applications of digital television, taking into account parameters related to usability. After analysis of data collected by the comparative study is possible to identify which device provides an interactive experience more interesting for users

Arquitetura para aplicações interativas imersivas de televisão digital

In this work, we propose a new approach to Interactive Digital Television (IDTV), aimed to explore the concepts of immersivity. Several architectures have been proposed to IDTV, but they did not explore coherently questions related to immersion. The goal of this thesis consists in defining formally what is immersion and interactivity for digital TV and how they may be used to improve user experience in this new televisive model. The approach raises questions such as the appropriate choice of equipment to assist in the sense of immersion, which forms of interaction between users can be exploited in the interaction-immersion context, if the environment where an immersive and interactive application is used can influence the user experience, and which new forms of interactivity between users, and interactivity among users and interactive applications can be explored with the use of immersion. As one of the goals of this proposal, we point out new solutions to these issues that require further studies. We intend to formalize the concepts that embrace interactivity in the brazilian system of digital TV. In an initial study, this definition is organized into categories or levels of interactivity. From this point are made analisis and specifications to achieve immersion using DTV. We pretend to make some case studies of immersive interactive applications for digital television in order to validate the proposed architecture. We also approach the use of remote devices anda proposal of middleware architecture that allows its use in conjunction with immersive interactive applications

Utilizando a televisão digital como um meio de comunicação para ambientes interativos reais

This Dissertation aims to provide a communication mechanism between Digital TV viewers and interaction devices, such as robots, for example, placed on the environment from which a TV program is being live broadcasted. Such communication mechanism has the objective to allow viewers controll the Interaction Devices through their TV devices, using the broadcast channel present in Interactive Digital TV systems, and receive data from the devices by the broadcast channel. This system was projected as a middlewaer system where the Interaction Devices in the TV program set are interconnected, creating a Interactive Device Network. With this approach, the system is capable of manage the devices on the network, controlling the flow of coming and leaving elements, in a transparent way for the viewers. The system yet allows the Interaction Devices communicate each other, with a integrated communication channel with no worries about the physical communication layer

Televisão analógica e televisão digital: o futuro do telejornalismo

This study proposes to present the process of implementation of Digital TV, the available resources found in the Japanese standard employed in the country and the form in which news programs will adapt to the new technology. Following the presentation of the technological tools, the current state of Brazilian television is discussed, focusing on two nationally broadcast programs, Jornal da Band on Bandeirantes channel and Jornal da Record on Record channel. As a case study, three editions of each show are evaluated with an individual and comparative analysis. Following the analyses, perspectives on the future of television journalism in the digital TV age are given. Additionally, the possibilities for interaction between the TV viewer and the channel and the forms of interaction that may exist within particular programs are discussed, thus allowing for active participation from the part of the viewer. The newly developed functions of journalists in the digital age are also broken down in the research. In order to gain a full understanding of the phases of this process of technological convergence and how programs will adapt to these tools, interviews with professionals who work in the production of televised news programs are conducted in the study

Interação humano-tv digital (IHTVD) e interatividade

With the development of Digital TV, the equipments are becoming more and more modernized in order to popular- ize the information that soon might reach all Brazilian families. That way, we open a space for discussion about the many directions that the usability applied on ISDB-Tb interactivity (Brazilian System of Digital Television) can take. This paper approaches the questions connected to the concept of usability and also the subjects related to the life cycle of some technologies (existence time, obsolescence) Also talks with the definition of interactivityon Digital Television since it is responsible for the emergence of a new contingent of interacting people which goes from the computer and portable equipments users to the passive TV viewers. It’s possible to conclude that the Human-Digital TV Interaction (HDTVI) comprehends the synergy between three actants on Digital TV: the col- lective (or not) TV viewer; the interface and the issuer who can be represented by an Artificial Intelligence (AI) service.

Televisão digital interativa na educação: desenvolvimento de um conteúdo. complementar ao ensino

This work had as objective the development of a prototype of educational content, as an experimental process, making use of resources from Interactive Digital TV. The characteristics of interactive digital terrestrial television are presented, in the form of a media mode capable of performing as a complementary source to education. The methodology used is composed of four phases: deduction, analysis, induction and synthesis. Its conception takes as issue the expressed need stated by UNESCO to use ICT (Information and Communications Technology) towards education, as well as the possibility of applying digital television in an educational process. The content is structured in the form of a quiz, a type of question-answer game as an informal way of education for high school students. The prototype developed in this work is presented as a structural script and map, taking into account the necessary activities and routines to put it into operation in the tested environments, eclipse, virtual set-top-box and Developer Box. The practice of prototyping was carried out in NCLua, based on middleware Ginga. As a result, we concluded that Ginga offers enough support to carry out the task, providing characteristics of interaction to publish the proposed content, at the moment of the actual practice.

Programas educativos a televisão digital ambientes propícios para a formação continuada de professores

Este artigo pretende trazer reflexões sobre as possibilidades da televisão digital para a formação continuada dos professores, a partir da produção e divulgação dos conteúdos formais e informais veiculados, ainda, analisar a teleducação como ferramenta de apoio à prática pedagógica interativa, envolvendo educadores, pesquisadores e demais profissionais da Educação e a formação de uma cultura digital que poderá colaborar com a formação continuada de professores, agentes fundamentais no processo educativo escolar, a partir da utilização das tecnologias da informação e comunicação (TIC). Para tanto, a formação do professor responsável pelo processo educativo requer a contí- nua atualização profissional para o ensino dos conteúdos com o auxílio dos veículos midiáticos digitais, tendo nos programas educativos da Televisão Digital (TVD) um recurso voltado à “instrumentalização” desses profissionais. A TVD, por meio da disponibilidade de acesso a conteúdos extras e da interação, poderá representar um ambiente tanto para o acesso, como de troca de experiências, vivências e conhecimentos.
