MScape

MScape got developed by Hewlett Packard as a platform to create location-based games
The platform was very flexible and encouraged developers to create not just games but also informational guides to sightseeings or practical information needed on worksites.
Events are triggered by a players location, so the player interacts with the software by moving from place to place.
Upon an event, video or audio snippets could be played or images and textes get shown.

Unfortunately the development of mscape got discontinued.
