This document discusses a joint research project between the Department of Philosophy and Cultural Heritage and the Department of Computer Science and Humanities at Ca' Foscari University of Venice. The project aims to create an interactive digital timeline of Venice using images, literature, artworks, and other sources from the 13th to 20th centuries. Technological challenges include developing new image search and matching techniques to extract information from large image datasets, and reconstructing immersive virtual environments representing different historical periods in Venice using layered information. The goal is to provide varying perspectives on urban places and cultural artifacts in Venice to help reconstruct the "Period eye."
