This paper describes participatory practices carried out with the intention of defining a new physical artifact of interaction for iDTV. Based on the results of these participatory practices and previous research results, we provide a definition of an artifact that can be adapted to diverse contexts of use.

This work presents the results of an experiment whose objective was to observe users' interactions ...

The present work approaches this topic under the perspective of the interaction design, a subject hardly explored in literature on Interactive Digital Television (iDTV), mainly in Brazil. The article presents a taxonomy for the physical devices of interaction -composed by hardware and software components -and a proposal of ways of using the traditional device for interaction with the iDTV. The proposal has basis in the nature of the interactive applications and in a profile of potential users. Results of this work could guide the choice and the formulation of proposals for new digital devices for interaction with iDTV.

This work presents and discusses a new proposal of artifact for interaction with iDTV applications. The paper presents in details the product design and the interaction language for the new digital artifact which presupposes its use by everyone, in the widest possible extension. Additionally, we show the prototype of these new hardware devices and an evaluation with prospective end users of the solution described in this paper.

The coexistence of an increasing number of facilities that make use of the remote control could result in more complex interfaces limiting its popularization. This article presents the challenges arising from the design and insertion of new digital devices for interaction of users with iDTV in Brazil. In addition it presents guidelines that could conduct to the design of new digital device for use with the television in future works.

In this paper we present an artifact for the requirements clarification activity, and suggest some activities in order to guide designers to take cultural issues into account. We situate our discussions in a practical context related to the development of social software for professionals of the Special ...

Neste artigo, apresentamos uma abordagem metodológica para a integração de laptops no ambiente escolar que tem base em conceitos e artefatos da Semiótica Organizacional, explorados de maneira participativa. Descrevemos os primeiros resultados de um Projeto que está sendo realizado com a participação ativa da comunidade de uma escola pública da periferia urbana de Campinas (SP) para a criação de soluções e processos contextualizados. Os resultados das primeiras cinco oficinas semio-participativas, realizadas in loco no espaço da escola, ilustram a viabilidade da proposta metodológica para inserção de laptops XO na escola. Os resultados indicam que a metodologia contribui para antecipar questões particulares ao contexto escolar específico, e pensar soluções de forma compartilhada com os envolvidos mais diretamente com a tecnologia nas práticas da escola, potencialmente promovendo transformações nessas práticas.

In this scenario, Information and Communication Technology, especially hypermedia systems, could benefit citizen, allowing access to knowledge, communication and collaboration. Current social networks systems were not conceived to address the challenges of an inclusive society. In this paper, we discuss some relevant design issues, elicited from a participatory approach, to the design of such systems. The exploratory design process starts with the elicitation of the different views among users, designers and developers, passes through design concepts definition and gets to a first approximation to a user interfaces design.

This work presents a quantitative analysis of an experiment conducted with twelve end-users in order to investigate the interaction of users with the hardware prototype of AIRs for iDTV. The experiment results presented in this paper indicate a positive acceptance of our solution and a good learning curve with respect to the interaction language of this physical artifact of interaction.
