- Anamorfoses e outras tecnologias imersivas no contexto da educação artísticaPublication . Flores, Manuel; Araújo, António; Figueiredo, MauroApresentamos uma proposta de investigação na área da média-arte digital onde se pretende combinar os princípios da anamorfose com as novas tecnologias baseadas na realidade aumentada. Esta perspetiva tem subjacente a ideia de que é possível relacionar a anamorfose cónica com as projeções realizadas em Realidade Aumentada. No âmbito desta investigação propõe-se uma abordagem ao estudo da perspetiva centrada nos contributos de Dürer e nos conceitos fundamentais da construção de anamorfoses. Pretende-se refletir sobre as possibilidades desta abordagem metodológica e analisar os seus contributos no desenvolvimento da capacidade de visualização espacial dos alunos do 3º ciclo do ensino básico e, desta forma, facilitar a compreensão dos conceitos relativos ao ensino da geometria.
- Anamorphosis: optical games with perspective's playful parentPublication . Araújo, AntónioWe explore conical anamorphosis in several variations and discuss its various constructions, both physical and diagrammatic. While exploring its playful aspect as a form of optical illusion, we argue against the prevalent perception of anamorphosis as a mere amusing derivative of perspective and defend the exact opposite view - that perspective is the derived concept, consisting of plane anamorphosis under arbitrary limitations and ad-hoc alterations. We show how to define vanishing points in the context of anamorphosis in a way that is valid for all anamorphs of the same set. We make brief observations regarding curvilinear perspectives, binocular anamorphoses, and color anamorphoses.
- Cardboarding mixed reality with Dürer MachinesPublication . Araújo, AntónioMixed reality is a direct application of 15 to 17th century principles of anamorphosis. The inherent physicality of anamorphosis, materialized through the Dürer perspective machine makes it an excellent teaching tool for students of digital art interested in mixed reality, whose initial core competencies may be extremely varied. The needs of these students are not met by the mere ephemera of learning how to use a particular piece of software; such knowledge is both transient and limiting of imaginative possibilities. We discuss a didactic strategy of cardboarding, i.e., a process of deliberate rudimentarization, to expose the inner workings of opaque chains of digital processes, to both clarify the elements of these chains and create loci for artistic intervention at their points of connection.
- Enhancement of Russian creative education: new post-graduation programme in digital art practicePublication . Marcos, A.; Amílcar, Martins; Saldanha, Ângela; Araújo, António; Carvalho, Elizabeth; Bidarra, José; Coelho, José; Shirley, Paulo; Veiga, Pedro; Cardoso, Vítor; Castilho, CarlosIn Project TEMPUS “Enhancement of Russian Creative Education: new Master Programme in Digital Arts in line with EU standards” (2014-2016) the Russian students had the opportunity to study in EU Universities for one semester. The Universidade Aberta, in Portugal, didn’t have a master degree in Digital Arts so a pilot programme had to be created: a new postgraduation in Digital Art Practice. This new curriculum, using blearning (based on online and face to face activities) with transdisciplinary methods, aims a practice oriented training on digital art. It started with a deep understanding of Lisbon, the relationship between people, cultural and artistic spaces and their environments. This knowledge inspired the students to produce and to create an artistic artefact presented in exhibition to an audience. With this postgraduation new possibilities started for reflection about global challenges for education in the millennium.
- Guidelines for drawing immersive panoramas in equirectangular perspectivePublication . Araújo, AntónioVirtual Reality (VR) Panoramas work by interactively creating immersive anamorphoses from spherical perspectives. These panoramas are usually photographic but a growing number of artists are making hand-drawn equirectangular perspectives in order to visualize them as VR panoramas. This is a practice with both artistic and didactic interest. However, these drawings are usually done by trial-and-error, with ad-hoc measurements and interpolation of precomputed grids, a process with considerable limitations.We develop in this work the analytic tools for plotting great circles, straight line images and their vanishing points, and then provide guidelines for achieving these constructions in good approximation without computer calculations, through descriptive geometry diagrams that can be executed using only ruler, compass, and protractor.
- Insights about an interactive film installationPublication . Mendes Da Silva, Bruno; Araújo, António; Tavares, Mirian; Costa, Susana; António, Rui; Monteiro, PaulaThe question of time and its relation to cinema is the common thread in this paper. Through research based on experimental practice, this paper explores, firstly, the psychosomatic processes that may give the viewer different perceptions of time. Secondly, it describes the working process of a film that intends to provide the viewer with the possibility of intervening in the film narrative in a disruptive way, seeking the possibility of subverting the filmic discourse.
