The term locative media refers generally to the communication technologies involving location; ie, those providing a link or information relating to a specific place via devices such as GPS, mobile telephones or PDAs, laptop computers or wireless networks. These media are now fully integrated into our daily lives and lead to a whole series of social, professional and cultural routines. Likewise, they have catalysed a certain level of curiosity and concern both in terms of artistic practice and academic study. In this issue of Artnodes, we want to contribute to the academic debate on locative media. We focus specifically on artistic projects that use these media for distinct aims, from political activism to games, or the different ways of appropriating these technologies. This allows us to see, from a conceptual perspective, that all these projects share an idea of the notion of space: how it is ordered, how it is represented, or what kind of social interaction takes place there. These are the underlying questions in each and every one of these locative media projects.
