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

Synchronizing Brazilian Sign Language (LIBRAS) on videos for Open Digital TV with educational purposes

The TV is a potential midia of communication that affects all social classes and it is available in 98% of Brazilian homes. It has been used as a distributor of educational materials since the 1950s. By 2016 the Open Digital TV (ODTV) in Brazil might cover the entire national territory, replacing the TV with analog signals. Concerns about accessibility for People with Special Needs (PSN) in that media have become more intense since the 1990s worldwide. In Brazil, it is estimated 24.6 million of PSN, 23% of them having some type of hearing loss. Of these, 2.9% are reported as deafs. Brazilian Sign Language (LIBRAS) is considered the first literacy language for deaf people in Brazil. In this context, this paper presents a proposal to facilitate the generation of educational content for ODTV based on two components. One is called SynchrLIBRAS and allows subtitles synchronization in Portuguese and a LIBRAS translator window of videos downloaded from the Web. The second component allows the visualization of this content through the Brazilian System of Digital TV and IPTV - environments that implement the middleware Ginga-NCL. The main focus of this paper is the presentation of the first component: SynchrLIBRAS. This proposal has educational purposes, contributing to teach LIBRAS to people who may collaborate with social inclusion of the deaf people.

Archives information publishing new design in post-custodial regime: The National Archives Experience Digital Vaults

The uses of Information and Communication Technologies (ICT) and Web environments for creation, treatment and availability of information have supported the emergence of new social-cultural patterns represented by convergences in textual, image and audio languages. This paper describes and analyzes the National Archives Experience Digital Vaults as a digital publishing web environment and as a cultural heritage. It is a complex system - synthesizer of information design options at information setting, provides new aesthetic aspects, but specially enlarges the cognition of the subjects who interact with the environment. It also enlarges the institutional spaces that guard the collective memory beyond its role of keeping the physical patrimony collected there. Digital Vaults lies as a mix of guide and interactive catalogue to be dealt in a ludic way. The publishing design of the information held on the Archives is meant to facilitate access to knowledge. The documents are organized in a dynamic and not chronological way. They are not divided in fonds or distinct categories, but in controlled interaction of documents previously indexed and linked by the software. The software creates information design and view of documental content that can be considered a new paradigm in Information Science and are part of post-custodial regime, independent from physical spaces and institutions. Information professionals must be prepared to understand and work with the paradigmatic changes described and represented by the new hybrid digital environments; hence the importance of this paper. Cyberspace interactivity between user and the content provided by the environment design provide cooperation, collaboration and sharing knowledge actions, all features of networks, transforming culture globally. © 2011 - IOS Press and the authors.

Sistema de chamada seletiva digital para controle de comunicações por ondas terrestres no Serviço Móvel Marítimo

As comunicações marítimas são ainda fortemente efetivadas por meio de circuitos rádio convencionais empregando ondas terrestres, em bandas de MF a VHF, especialmente após a introdução de sistemática de chamadas seletivas digitais. Entretanto, um número significativo de procedimentos operacionais nas radiocomunicações ainda depende de intervenções de operador, reduzindo sua eficiência e dando margem ao cometimento de erros como emissão de falsos alarmes de socorro. Esses erros têm sido frequentes e têm ocasionado muito desvio de atenção das ocorrências reais e perdas de tempo nas instâncias que cuidam das ações de busca e salvamento no mar, afetando, seriamente, a confiabilidade no processo de comunicações terrestres. Em vista disto, propõem-se, nesta pesquisa, sistemáticas para controle das emissões de falsos alertas de socorro, nas transmissões por ondas terrestres, e para melhorar o processo vigente de transmissão de chamadas. As chamadas de socorro recebidas pelas estações costeiras são identificadas por estas, de acordo com as estações que as emitiu, objetivando subsidiar ações corretivas por instâncias competenrtes, para inibição de novas ocorrências. Paralelamente, maior nível de automação é proposto para os processos de chamadas, reduzindo-se a dependência de procedimentos manuais e, assim, as possibilidades de emissões equivocadas, além de melhor aproveitar o conceito de chamada seletiva do sistema vigente. Tais proposições dão maior eficiência e confiabilidade às comunições terrestres, úteis especialmente nas situações de emergências, sem adicionar significativas demandas operacionais nas estações, incentivando e melhorando as condições de comunicações no SMM por ondas terrestres.
