Mscape was a mobile media gaming platform developed by Hewlett Packard that could be used to create location-based games. The development of Mscape was discontinued (and its website mscapers.com shut down) on March 31, 2010.
The Mscape platform is flexible. HP encourages developers to use Mscape to create not just games, but also informational guides to points of interest, imaginative stories about places, and practical information about worksites. Mscape makes a player's GPS location an element of the gameplay. Events in a game are triggered by a player's location, and the player interacts with a game by moving from place to place.
Mscape is used to create mediascapes, interactive experiences made up of video, audio, images, and text. Mscape stores the digital media files in a structure that associates them with positions from a GPS system. Players play mediascapes on a Windows Mobile device, such as a mobile phone or a PDA, that's GPS enabled. As players move around, the device senses their position and activates the appropriate media files.
