Abstract: A system and method for delivering contextually enhanced location based media for tour guidance. Tours are constructed upon a directional tour route, the route potentially comprising optional parts. Media is associated with tour points and is delivered based on position and order along the directional tour route. Tour points also have characteristics and priorities which also affect determination of media delivery. The system can also make use of non-spatial contextually relevant data such as tour history, temporal factors and velocity in determining media selection. The system can dynamically mix multiple channels of triggered media in real time, and can adjust properties of the playing media in response to predicted movements along the route.
