Biblioteca de Arte Inclusiva: Informação e Conhecimento Acessíveis aos Leitores com Deficiência Visual

O presente relatório descreve a atividade realizada na Biblioteca de Arte da Fundação Calouste Gulbenkian, no âmbito do Mestrado em Ciências da Informação e da Documentação, tendo por tema o acesso à informação pelos leitores com deficiência visual. Nele procura-se abordar que medidas têm sido tomadas para assegurar a integração destes leitores, tendo em vista alcançar a sua autonomia a nível de utilização dos serviços disponíveis. Nesse sentido, explicitam-se os conceitos inerentes a esta temática (biblioteca inclusiva e acessibilidade), destaca-se a importância da interação com outros utilizadores como forma de integração, refere-se a importância da cooperação interinstitucional, salienta-se o papel do bibliotecário e das tecnologias de informação e da comunicação, como meio de permitir ao deficiente visual aceder a um conjunto diversificado de serviços, através da utilização de equipamentos e software específicos. Através da aplicação de uma metodologia de pesquisa bibliográfica, observação direta e entrevista, efetua-se um estudo de caso com uma análise detalhada ao nível da acessibilidade física e dos recursos materiais assim como da atitude e preparação dos profissionais para lidar com a deficiência. Conclui-se que a Biblioteca de Arte deve continuar a investir na exploração de novos recursos e potencialidades, de modo a disponibilizar todo o tipo de meios humanos e tecnológicos para apoiar os leitores com deficiência visual, promovendo a sua inclusão e participação na sociedade da informação e do conhecimento.

Visual and verbal processing effects on human memory

In this study in the field of Consumer Behavior, brand name memory of consumers with regard to verbal and visual incongruent and congruent information such as memory structure of brands was tested. Hence, four experimental groups with different constellations of verbal and visual congruity and incongruity were created to compare their brand name memory performance. The experiment was conducted in several classes with 128 students, each group with 32 participants. It was found that brands, which are presented in a congruent or moderately incongruent relation to their brand schema, result in a better brand recall than their incongruent counterparts. A difference between visual congruity and moderately incongruity could not be confirmed. In contrast to visual incongruent information, verbal incongruent information does not result in a worse brand recall performance.

Video metadata extraction in a videoMail system

Currently the world swiftly adapts to visual communication. Online services like YouTube and Vine show that video is no longer the domain of broadcast television only. Video is used for different purposes like entertainment, information, education or communication. The rapid growth of today’s video archives with sparsely available editorial data creates a big problem of its retrieval. The humans see a video like a complex interplay of cognitive concepts. As a result there is a need to build a bridge between numeric values and semantic concepts. This establishes a connection that will facilitate videos’ retrieval by humans. The critical aspect of this bridge is video annotation. The process could be done manually or automatically. Manual annotation is very tedious, subjective and expensive. Therefore automatic annotation is being actively studied. In this thesis we focus on the multimedia content automatic annotation. Namely the use of analysis techniques for information retrieval allowing to automatically extract metadata from video in a videomail system. Furthermore the identification of text, people, actions, spaces, objects, including animals and plants. Hence it will be possible to align multimedia content with the text presented in the email message and the creation of applications for semantic video database indexing and retrieving.

Minimal computation structures for visual information applications based on printed electronics

In the early nineties, Mark Weiser wrote a series of seminal papers that introduced the concept of Ubiquitous Computing. According to Weiser, computers require too much attention from the user, drawing his focus from the tasks at hand. Instead of being the centre of attention, computers should be so natural that they would vanish into the human environment. Computers become not only truly pervasive but also effectively invisible and unobtrusive to the user. This requires not only for smaller, cheaper and low power consumption computers, but also for equally convenient display solutions that can be harmoniously integrated into our surroundings. With the advent of Printed Electronics, new ways to link the physical and the digital worlds became available. By combining common printing techniques such as inkjet printing with electro-optical functional inks, it is starting to be possible not only to mass-produce extremely thin, flexible and cost effective electronic circuits but also to introduce electronic functionalities into products where it was previously unavailable. Indeed, Printed Electronics is enabling the creation of novel sensing and display elements for interactive devices, free of form factor. At the same time, the rise in the availability and affordability of digital fabrication technologies, namely of 3D printers, to the average consumer is fostering a new industrial (digital) revolution and the democratisation of innovation. Nowadays, end-users are already able to custom design and manufacture on demand their own physical products, according to their own needs. In the future, they will be able to fabricate interactive digital devices with user-specific form and functionality from the comfort of their homes. This thesis explores how task-specific, low computation, interactive devices capable of presenting dynamic visual information can be created using Printed Electronics technologies, whilst following an approach based on the ideals behind Personal Fabrication. Focus is given on the use of printed electrochromic displays as a medium for delivering dynamic digital information. According to the architecture of the displays, several approaches are highlighted and categorised. Furthermore, a pictorial computation model based on extended cellular automata principles is used to programme dynamic simulation models into matrix-based electrochromic displays. Envisaged applications include the modelling of physical, chemical, biological, and environmental phenomena.

A cenografia oitocentista como fonte de cultura visual e de ideologia

A argumentação centra-se na história da produção cenográfica da segunda metade do século XIX em Portugal, propondo um tratamento teórico mais abrangente, que desloque o enfoque analítico da peça de arte em si ou do carácter efémero e global da espectacularidade que tem merecido alguma atenção da historiografia contemporânea, para uma escala de cultura visual ou mesmo de visualidade, no sentido mais dilatado destas expressões. Discutindo essencialmente a problemática em torno da imagem teatral como produto do mundo oitocentista analisa-se o potencial cognitivo da série cenográfica na sua capacidade de representação e apropriações ideológicas. Para esta dialéctica concorrem as repercussões epocais do espectáculo, designadamente na regulação da vida social, na mediação de processos económicos, no combate político, e sobretudo, em modelos de percepção artística fundados nos convencionalismos cenográficos como acontece, por exemplo, na produção decorativa e arquitectónica integradas num particular campo visual ou na teatralidade actuante dos edifícios, cuja essência, em todos os casos, é devedora de uma cultura paradoxalmente centrada nos limites da caixa cénica e na infinitude emotiva do espectacular.

Revolution in Crisis: The Ruptures of Revolution and Ruptured Revolutions Through the Ruptures of Artistic Practice

This article proposes an investigation of the history and memory of the Carnation Revolution through the lens of contemporary art. Drawing upon the argument according to which history and memory are investigated by visual artists by means other, but no less relevant, than those of professional historians, this article will argue for the importance of attending to the visual, auditory, textual, object- and research-based ways in which artists from several generations and geographies have been unearthing the repressed histories and memories of the Carnation Revolution in Portugal and of anticolonial struggles, decolonization and post-independence nation-building in Mozambique, Guinea-Bissau and Angola. The discussion focuses on several works by Ângela Ferreira, but attention will also be paid to precursors in imaging the Revolution, such as Ana Hatherly, and to a younger generation of artists such as Filipa César, Kiluanji Kia Henda and Daniel Barroca.
