The objective of this course, is to introduce the participants to location-based games and to the challenges relating to designing them. Key characteristics of this new genre are introduced first, followed by a design framework and a set of design guidelines. Examples of location-based games will be presented and typical design patterns as extracted from previous workshops will be discussed. This course has already been run in the frame of several conferences and summer schools (Sintoris 2015). Typical course participants include interaction designers, game designers and developers, practitioners and researchers interested in location-based games. The course is presented by researchers who have been involved in designing and studying human interaction with location-based games for many years. Examples of games developed by the course organizers include MuseumScrabble, RebelsVsSpies, Taggling, etc.
