Through the Project "Interactive Heraklion (digital applications for the promotion of the sustainable urban development intervention area)", cutting-edge technologies were developed to provide access to digital content related to the area in four alternative ways: (a) on-site; (b) remotely, at events and exhibitions; (c) via the web, using fixed and mobile devices; and (d) through the existing information and tourism promotion infrastructure of the Municipality. For the promotion of cultural routes and points of interest in the intervention area, the following have been produced: (a) a script and 360o high-definition video productions; (b) production of 3D models and virtual characters; and (c) production of thematic audio narratives, using techniques and systems of "story telling" for the innovative/interactive presentation of exhibits/events in places of cultural and tourist interest in Crete.
