City Explorer Choose location Occupy Objects Validate • S. Matyas. Playful Geospatial Data Acquisition by Location-based Gaming Communities, IJVR 2007 • S. Matyas, H. Mitarai, M. Kamata. Designing Location-based Mobile Games with a Purpose – Collecting Geospatial Data with CityExplorer, ACE 2008 • Played like a Carcassonne board game • The map is divided into several Regions • At the beginning, the whole map is “hidden” • Before each round, every player choose several kinds of real world objects • e.g. player A chooses “bar & church”; player B chooses ”garden & restaurant” • Players occupy objects by placing one “token” on each • e.g. put one token to locate one bar in the real world • Tokens can be only placed on locations of chosen object categories • At the end of each round, who holds the majority of game tokens in each Region occupy the region and gets points
City Explorer (cont’) • No Assignment • Players tag according to Carcassonne rules • In IJVR 2007, the author also 1discusses critical elements of location-based games, provided a framework, and take GeoTicTacToe and CityPoker as case studies

CityPoker fig. 1 Starting situation in CityPoker • C. Schlieder. Representing the Meaning of Spatial Behavior by Spatially Grounded Intentional Systems, In: M. A. Rodríguez et al. (Eds.): Geospatial Semantics, LNCS 3799, pp. 30 – 44, Berlin: Springer, 2005. • CityPoker an adapted poker game • players start with a hand of 5 cards (fig. 1) • They try to improve their starting hand by changing cards at 15 locations (only 5 of which contains cards) in the real world • One player can change one card from the cache, and he can change form cache only once. • System • analyzes the tracks => model the behavior of players & the user intentions. • Then, provide intention service automatically according to the user intentions • e.g. display large scale map when the player intends to GetCard • Locolization: GPS
Playing on a Line - Alak board game Go • P. Kiefer, S. Matyas, C. Schlieder. Playing on a Line: Location-based Games for Liner Trips.
