Abstract: In this work we launch a discussion about the use of virtual reality (VR) to reproduce multi-sensorial experiences. In our perspective, it is important to understand that more than providing a realistic audiovisual experience through a digital display, the actual generation of VR devices generates additional sensorial stimuli in the user perception experience with a synthetic environment. For example, with a head-mounted display (HMD), a motion tracking system and voice recognition would be possible to recreate more sensations of the real world in an artificial context (touch, haptic responses, voice commands, 360º space visualization).

Abstract: This work demonstrates the methodological approach we applied to develop a fully immersive and interactive virtual environment that simulates Itapeva’s archaeological site, in Brazil. To create a realistic 3D demo, which would be relevant for research through a cyber-archaeology exploration, specific technological equipment to collect data were used, such as: laser scanner and image-based modeling. In consequence, data acquisition from these apparatus generated a huge density point clouds, requiring a many gigabytes computer storage and a research work to simplify the information in a user’s friendly virtual model. Also, to provide an immersive feeling when exploring the virtual reality we allow users to navigate through the scene using 3D input devices and head-mounted display to visualize the aesthetical and spatial elements. In resume, through a sophisticated digital simulation environment we created a telepresence sense where archaeologists can explore landscapes and its objects through a not destructive way.

Resumo: This article aims to discuss the consequences of simulating the individual’s experience with out-of-home advertising through a computer screen. It means, it is an essay focused on the debate and reflection about applying digital narratives as resource to preserve, to explore and, even, to optimize our relationship with this kind of media (so related to the city space). There is no intention to replace any real world action, but yes to preserve it (memorizing the past), to understand it (studying the present) and to optimize it (testing the future) by the digital ways. In resume, the work launches a tecnoliberal thought, because it looks to new technologies as a potential instrument to improve our relationship with the city space. The debate goes beyond theoretical references (Baudrillard, 1994, Negroponte, 1995; Kerckhove, 1995; Castells, 1999; Lévy, 1999; Virilio, 2000, Manovich, 2001; Jenkins, 2003; Mesquita, 2006; Viana, 2009; Martins, 2010; Zagalo, 2010; Pires, 2010; Zilles Borba, 2013) when makes use of a specific digital prototype, developed by the authors as part of a doctoral degree program about the virtual reality transposition of the physical communication experience among observer, advertising and urban space. On this way, as basis for extracting qualitative data, this digital model is empirically investigated. As a walker who observes billboard images in the streets, the authors carried on an exploratory observation, which was fundamental to get the receptor feelings in the synthetic scenario and, in consequence, to reflect about the paradigm of time, space and materiality in technological simulations. We do underline those three example: a) preserving ephemeral images which do reflect cultures, costumes and technologies of the people in some time of History (with binary technics); b) exploring the advertising in a digital model who allows to visualize the city space through the avatar’s eyes (with visual, graphics and immersive technics); and c) optimizing the communication experience by testing and researching variables in the virtual world before applying it in the physical one (design and programming technics).

Body, image and (urban) space. Illusions of the physical presence in out-of-home advertising observation experience through a computer screen

Resumo: This article aims to discuss the individual's immersive experience when exploring advertising images through a virtual world that reconstructs the visual and structural logics of a real city. This means, that its focus is based on a discussion and reflection of factors that drives the person psychologic dive (outside the screen) into a digital simulation (inside the screen). The decision on studying this communication experience is justified by the visual, corporal and spatial intensity relation among observer, image and space, even when reproduced by three-dimensional technics specifics for the computer screen language. In this sense, when transposed to the virtual universe this interaction so linked to the physical world allows to think about a series of problems/questions, not only related to the advertising image (how does the individual recognizes the message?), but, also, how he/she understands this new notion of materiality, objects, space, body and even the own reality? To this end, through a digital model developed by the author, as research process in a doctoral thesis, concluded in 2013, is recreated with computer graphics and programming the way pedestrian experiences, when walking around a small zone of the city of Porto, Portugal, the aesthetic (scenario) and the semantic (communication) of an advertising billboard affixed to a giant architectural structure in the landscape.
