===Tourism and sightseeing===
Travelers may use AR to access real-time informational displays regarding a location, its features, and comments or content provided by previous visitors. Advanced AR applications include simulations of historical events, places, and objects rendered into the landscape.<ref>Saenz, Aaron [http://singularityhub.com/2009/11/19/augmented-reality-does-time-travel-tourism/ Augmented Reality Does Time Travel Tourism] ''SingularityHUB'' 19 November 2009.</ref><ref>Sung, Dan [http://www.pocket-lint.com/news/38806/augmented-reality-travel-tourism-apps Augmented reality in action – travel and tourism] ''Pocket-lint'' 2 March 2011.</ref><ref>Dawson, Jim [http://www.livescience.com/5644-augmented-reality-reveals-history-tourists.html Augmented Reality Reveals History to Tourists] ''Life Science'' 16 August 2009.</ref>

AR applications linked to geographic locations present location information by audio, announcing features of interest at a particular site as they become visible to the user.<ref>{{Cite journal | doi=10.1111/j.1467-9671.2006.00244.x| title=Development of a Speech-Based Augmented Reality System to Support Exploration of Cityscape| journal=Transactions in GIS| volume=10| pages=63–86| year=2006| last1=Bartie| first1=Phil J.| last2=MacKaness| first2=William A.| issue=1| bibcode=2006TrGIS..10...63B| s2cid=13325561}}</ref><ref>Benderson, Benjamin B.
