A co-evolutionary interaction design of digital TV applications based on verbal decision analysis of user experiences

Since mobile TV represents a new paradigm for interaction design, many different candidate solutions of interaction can be possible. Following this concept, a study was accomplished with the objective of finding a better interaction solution for an application of mobile digital TV. Three executable prototypes of an application of mobile TV were built. A multicriteria model of verbal decision analysis was applied to those three alternatives by aiming at investigating the favourite characteristics of each prototype based on users experience and their intentions of use. This model resulted in a method that supports designers in the qualitative analysis of alternatives and collaborative conception of the best solution of interaction to innovative products.

A Model for Mobile Television Applications Based on Verbal Decision Analysis

The emergence of Digital Television - DTV brings the necessity to select an interface that may be used in Digital Television for Mobile Devices. Many different candidate solutions for interaction applications can be possible. This way, usability specialists prototyped interfaces that were analyzed according to users’ preferences through usability test, considering criteria classified in accordance with users’ preferences and alternatives, which were obtained from a ranking modeled by verbal decision analysis. Results revealed great influence of the application’s functions evidence in the ease of navigation.

Analysis of the Interaction Design for Mobile TV Applications Based on Multicriteria

Since mobile TV represents a new paradigm for interaction design, many different candidate solutions of interaction can be possible. There is not yet any work that explores how to consider the users’ experience with technology to analyze the best solution(s) to the interaction design of a mobile TV application. This report brings an experience about what criteria addressing users’ experience influence designers to make a decision. A qualitative analysis was performed for different solutions and was based on a multicriteria approach. These criteria were classified in accordance with users’ preferences and their intentions of use, which were obtained from a ranking modeled with the ZAPROS III multicriteria method. Results revealed great influence of the users’ familiarity with applications in the ease of navigation.

Towards for Analyzing Alternatives of Interaction Design Based on Verbal Decision Analysis of User Experience

In domains (as digital TV, smart home, and tangible interfaces) that represent a new paradigm of interactivity, the decision of the most appropriate interaction design solution is a challenge. HCI researchers have promoted in their works the validation of design alternative solutions with users before producing the final solution. User experience with technology is a subject that has also gained ground in these works in order to analyze the appropriate solution(s). Following this concept, a study was accomplished under the objective of finding a better interaction solution for an application of mobile TV. Three executable applications of mobile TV prototypes were built. A Verbal Decision Analysis model was applied on the investigations for the favorite characteristics in each prototype based on the userâ??s experience and their intentions of use. This model led a performance of a qualitative analysis which objectified the design of a new prototype.

Mapeamento de um portal de acesso de televisão digital em dispositivos móveis

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.

Creation of pre-patterns in a system of content creation for digital television

This paper aims to present an approach for the creation of pre-patterns from experience of use in creating content for digital television. We conducted an experience of use for the development and application of pre-patterns in the interaction design. This paper presents the main contributions to the description of pre-patterns for the context of creating content for DTV, and an analysis of the implications of these for the design of interaction.

Requisitos para Elaboração e Integração de Conteúdos com Recursos da TV Digital Brasileira aplicados em Experiências de Aprendizado

Este artigo discute a colaboracao entre estudantes na internet e a troca de conhecimento por meio desse canal de comunicacao. Propoe uma metodologia que visa potencializar as relacoes entre os usuarios de uma rede educacional situada num contexto especifico. Tal metodo tem como fundamento as teorias do contexto e a analise de redes sociais (ARS), para promover um mapeamento das redes estudadas.Refletir sobre curriculo escolar formal e comunidades de aprendizagem como metafora das TIC dinamizam os caminhos empiricos, construcoes criticas e aprofundamento da difusao do conhecimento como parte do processo de humanizacao/ tecnologizacao do homem. Oriundos de processos e movimentos contemporâneos, a consolidacao de ambientes computacionais nas escolas potencializa a construcao do conhecimento e a socializacao de praticas pedagogicas inovadoras. Esta investigacao assume as situacoes especificas curriculares, procura descobrir o que existe de mais essencial e caracteristico, partindo do conhecimento de curriculo e suas bases teoricas tradicionais, para a construcao da discussao sobre um curriculo em rede associada a instrumentalizacao das comunidades de aprendizagem.O sistema Moodle constitui-se atualmente numa das mais importantes ferramentas de apoio a cursos na Web. Apesar disto, seu modelo apresenta algumas deficiencias para uma estruturacao hierarquica e compartilhamento de materiais digitais entre disciplinas e turmas do seu ambiente virtual. Este artigo apresenta um estudo sobre a arquitetura central do Moodle, propondo a definicao de um novo nucleo, visando o aprimoramento destas caracteristicas.Estudo descritivo, qualitativo, com estudantes da 3a serie de Graduacao em Enfermagem de uma Universidade Publica de Sao Paulo, SP. Os participantes construiram Mapas Conceituais, por meio do software Cmap Tools®. Os dados foram coletados em um Grupo Focal e todos os sujeitos indicaram que o uso do software facilita e garante a organizacao, visualizacao e correlacao dos dados, porem houve dificuldades iniciais relacionadas ao manejo das ferramentas. Conclui-se, que o software Cmap Tools® favoreceu a construcao dos MC por seus recursos de formatacao, porem estrategias de orientacao deveriam ser implantadas. Como resultado, desenvolveu-se um manual para o uso do software Cmap Tool® em video Podcasting.Ha poucas iniciativas com respeito aos ambientes de virtuais para a divulgacao de materiais curriculares sobre modelagem matematica. Esses ambientes oferecem acesso as praticas pedagogicas em modelagem. Este trabalho apresenta um sistema Web para hospedar atividades de modelagem e materiais multimidia para descrever o desenvolvimento do ambiente de modelagem em sala de aula e apoiar outros professores na implementacao em suas praticas pedagogicas.A composicao e sequenciamento de Objetos de Aprendizagem sao discutidas neste trabalho a partir da representacao da estrutura conceitual de um dominio em termos das suas relacoes de dependencia. A composicao de Objetos de Aprendizagem e modelada a partir da estrutura narrativa de um discurso considerando-se os aspetos formais dos planos do conteudo e de expressao. O aspecto formal do conteudo da composicao e dado pelas pelos conceitos e seus relacionamentos e forma da expressao corresponde aos tipos de signos definidos pelo LOM. A estrutura da composicao obtida independe do tipo de midia utilizado e o modelo adequa-se as propostas de composicao adaptativas tanto do ponto de vista do meio como das disponibilidades de conexao.

Specification of Interaction of Digital TV Applications in Converged Scenarios and Using Pre-patterns

The possibility of convergence of interactive digital television to other devices enables various usage scenarios. Such scenarios must be studied to assess their viability. This paper aims to present the use of pre-patterns in specification of scenarios of converged applications for interactive digital television in order to validate the usage scenarios and to define their interaction design.
