TIDE, or 'Atlantic Network for Developing Historical Maritime Tourism' project, will aid organisations and practitioners in the Atlantic region tourism development sector in identification of potential niche tourism packages. TIDE will use Virtual Reality (VR) and Augmented Reality (AR) in archaeology and submarine exploration fields to enrich visitor experiences and introduce an exciting new dimension to tourism and cultural heritage of the Atlantic regions. The framework will be piloted with particular focus on the Napoleonic, Spanish Armada, World Wars and Atlantic Migrations eras.
