Architectural graphics and the experience of space. Freehand drawing and photograph to deepen on communicative qualities in linear perspective

Abstract

Architecture communication on photo-sharing social networking services like Instagram focuses on photorealism. Meanwhile, the conceptual intention or the experience of the architectural space has less impact in these media. Some architectural graphics techniques are closer to this purpose due to their nature. The main objective is to identify the visual qualities of the architectural space experience from a linear perspective. To do this, the research proposes the design of a visual pattern recognition tool and applies it to pairs of images (photography and drawing) from the same place. The results provide the strategy design based on five variables: the level of human presence, the distortion of perspective, the chromatic distortion, the overlay realism and the emphasis. Finally, the visual summaries lead to values that help to understand the communicative qualities of the experience of space due to their ability to compare main milestones of visual information.
