    Animated urban surfaces : spatial augmented reality in public discourse
    (Lusofona University, 2021) Tritthart, Martina; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    Today´s projection art on public surfaces developed from the mutual approximation of painting, architecture, and lighting during centuries. The terms “Spatial Augmented Reality” (SAR) and “projection mapping” describe mostly temporary large screen projections on urban surfaces. The façade architecture becomes the screen for the content, mostly projected 2D and 3D animations. In essence, many of these artworks generate illusionistic clips deriving from the existing façade structure, allowing reality and fiction to merge audio visually. Artists, architects, curators, and institutions are increasingly aware of their responsibility related to this form of the mediatization of architecture, as shown, for example, by the Brazilian artist group Visualfarm. Their members approach their work as a counterpoint to the commercialization of public space in its appropriation by industry, propaganda, and advertising. But on the other hand, they also make a living from commercial assignments. Artists and architects often see themselves as pioneers and experimental researchers for possible developments in the coming digitized cities. By presenting various examples by selected artists like Corrie Francis Parks, Pablo Valbuena and Robert Seidel, the role of animation in connection with an alternative approach to the concepts of augmented realities within this process of social and urban evolution will be discussed. These artists try to integrate digital content into the cityscape in a harmonious sense.

    Augmenting the city : the photo-realistic animation of a historic building and its influence on spatial perception and meaning
    (Lusofona University, 2021) Schweiger, Moritz; Wimmer, Jeffrey; Nagler, Gregor; Schlagowski, Ruben; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    Augmented Reality (AR), defined as the holographic overlay of physical space with virtual objects in real time (Azuma, 1997), can be considered a prime example of mediatization. This development is particularly evident in the public space of the “mediatised city” (Hepp, Simon & Sowinska, 2018), being a focal point of the latest media technologies already overlaid with a multitude of AR content. But how does AR change the perception and meaning of urban space? And how can researchers capture methodically the appropriation of complex, large-scaled AR content experienced via high-tech AR glasses? To answer these questions, a historical building, that had been destroyed during the Second World War, was reconstructed as a holographic animation on a public city square. In order to resurrect this building in AR, old photographs, paintings and postcards were evaluated and used to create a virtual model in the original size and place it at its original location. The test subjects were then able to view the hologram from various different angles using AR glasses (Microsoft HoloLens 2), move freely around the square and even enter it. Combining quantitative, before-and-after questionnaires and qualitative thinking-aloud protocols, our results show that the holographic animation of a historical building can influence both the sensual-aesthetic perception and the personal meaning of a public square for city dwellers. Specifically, our test subjects perceived differences in its accessibility, coherence and aesthetics, simplicity, atmosphere and legibility. The meaning of the square was altered with regard to personal memories (= the self), typical groups of people (= others) and certain opportunities (= environment) associated with it by city dwellers.
