The present paper describes a model combining augmented reality and artificial intelligence algorithms in a 3D model of an area of the city of Coimbra, based on information extracted from OpenStreetMap. The augmented reality effect is achieved using a video projection over a 3D printed map. Users can interact with the model using a smart phone or similar device and simulate itineraries which are optimized using a genetic algorithm and A*. Among other applications, the model can be used for tourists or travelers to simulate travels with realism, as well as virtual reconstructions of historical places or remote areas.<\/jats:p>","DOI":"10.3390\/a12070140","type":"journal-article","created":{"date-parts":[[2019,7,12]],"date-time":"2019-07-12T11:49:38Z","timestamp":1562932178000},"page":"140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Projected Augmented Reality Intelligent Model of a City Area with Path Optimization"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4313-7966","authenticated-orcid":false,"given":"Mateus","family":"Mendes","sequence":"first","affiliation":[{"name":"Polytechnic Institute of Coimbra\u2014ESTGOH and Institute of Systems and Robotics of the University of Coimbra, 3045-093 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4837-4349","authenticated-orcid":false,"given":"Jorge","family":"Almeida","sequence":"additional","affiliation":[{"name":"Polytechnic Institute of Coimbra\u2014ISEC, 3030-199 Coimbra, Portugal"}]},{"given":"Hajji","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Haute \u00c9cole Bruxelles-Brabant (ISIB), 1180 Brussels, Belgium"}]},{"given":"Rudi","family":"Giot","sequence":"additional","affiliation":[{"name":"Haute \u00c9cole Bruxelles-Brabant (ISIB), 1180 Brussels, Belgium"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Chuah, S.H.W.
