MART-MAF: Media file format for AR tour guide service

Abstract

We are currently developing a new tour guide service on mobile phone using augmented reality. Among the components for the service, in-situ annotation is one of the most important components for capturing of lots of personal experiences in the form of digital multimedia during his/her trip. Our in-situ annotation system provides several pieces of functionality that include recording MART (Mobile Augmented Reality based Tour) media format, transmitting the recorded media and retrieving the related experiences of others. MART media data should be easy for users to store, interchange and manage. Additionally, it can integrate various types of media, such as video, audio, GPS data, motion, 2D/3D graphics and annotated texts. For this, we define a new format for MART media, called MART-MAF, which can compose MPEG standards and non-MPEG standards for various kinds of media.
