Tracklines is a Global Heart Rate research project founded in a rigorous cycle of technical and aesthetic innovation. It's a trail-based mobile media installation; a guided experience where hikers use GPS smartphones to navigate a mountainous landscape seeded locatively with stories. Think of it as a 'walkumentary' - a wild stroll of imagination combining elements of documentary and trail-guiding with some very old patterns of storytelling, and very new innovations in location-based digital delivery.

As a research project hosted by the BNMI's Mobile Lab, the investigations behind Tracklines are multi-fold, exploring the place where nature, culture, and technology converge in mobile media experience design.
