<p><strong>Abstract.</strong> The study presents a process of digital simulation that aims to investigate the legibility of multiple spaces in a complex architecture through architectural survey, virtual reconstruction and 3D visualization in immersive environment. The collaboration between two research institutions, one Italian and the other Chinese, developed a reconstruction of a building in the campus of the Tsinghua University of Beijing using digital tools, in order to understand the behaviours during the fruition of that space. Digital simulation in the visibility theme guarantees the possibility of testing multiple configurations and showing the impacts of the different environmental hypothesis.</p>

Despite long-standing practices in human augmentation, the field of Augmented Cognition still lacks a generalized ‘theory of augmentation’ which guides the selection of such augmentations. We do not yet have a taxonomy that could help understand which augmentation to use to address which type of cognitive problem. By reviewing past applications of cognitive augmentation, this paper provides a framework that helps navigating the growing knowledge and guides the selection of cognitive-enhancing augmentations. Like a compass, the proposed taxonomy can be used to map previous steps in the field, to navigate the current state of the art, and to orient future research directions.
