Projection-based city atlas: An interactive, touchless, virtual tour of the urban fabric of Ascoli Piceno

摘要

This proposal is aimed at illustrating a low cost exhibit of a projection-based city atlas. The exhibit could be replicated and reconfigured in accordance with the size of the mock-up and the spatial arrangement of the place where it will be located. The paper will be divided into different sections in order to explain and illustrate: the state of the art and previous experiences about spatial augmented geographycal representation; the technical issues regarding the projection set-up and the technological framework related to the touchless interaction system; the content design process. Within this framework, the experimentation has been carried out on the urban area of Ascoli Piceno (Italy). Based on the description of events occurring over time, the interactive virtual tour aims to highlight how the urban fabric has changed throughout the historical and political periods that have affected the city.
