features that expand the contractual magic circle of play spatially, temporally, or socially", in other words "expand the boundaries of play". From the user experience perspective, Arango-López et al. propose a new definition, taking into account the given basis by Montola and their own experience in the game's development. They define that: "A pervasive game delivers to the player an enriched experience of the game through an evolvement of the dynamics of the game, expanding the space of the game according to the context where it is played. This allows breaking the boundaries of the game world, making reality part of it and that the elements in that really have an influence during the game". They delved in the special features and added a component diagram of the pervasive games, it is based on the pervasive narrative of videogames. History The first time the word "pervasive" was applied to gaming is around March or April 2001, by Jennica Falk, in an article referring to the environment of the game, rather than the game itself. That same year Jay Schneider and Gerd Kortuem coined the term "pervasive gaming", admitting that they derived the term from pervasive computing. Although the origins of ubiquitous computing and pervasive computing differ, they are often used interchangeably and both are the basis for pervasive gaming. Specifically, it is the technological perspective of pervasive games that borrows from both the cultural and the technological perspectives of pervasive computing. And, because ubiquitous computing and pervasive computing have been intermingled in the past, they both influence pervasive games. At the Computer Science Lab at Xerox PARC in 1988, Mark Weiser set up a "ubiquitous computing" research program to "conceive a new way of thinking about computers in the world, one that takes into account the natural human environment and allows the computers themselves to vanish into the background". The program was designed such that computers were to cater to the wishes of the user, being of various sizes, aware of their location and easy to use. In 1998, Mark Bregman at IBM introduced "pervasive computing" as a commercial aspect where people have quick access to services anytime and anywhere. Initially, the concepts of ubiquitous computing and pervasive computing were from different perspectives, but the two concepts were continuously redefined and related to other terms and concepts, leading to confusion and ambiguity.
