Abstract

The growing ubiquity and usability of smart mobile phones can be exploited to develop popular and realistic pervasive computing applications. Adding image processing capabilities to a mobile phone equipped with a built-in camera makes it an easy-to-use device for linking physical objects to a networked computing environment. This chapter describes an extensible and portable programming platform that, using bi-dimensional visual tags, turns mass-market camera-phones into a system able to capture digital information from real objects, use such information to download specific application code, and act as a GUI for interacting with object-dependent computational services. The system includes a module for on-phone extraction of visual coded information and supports the dynamic download of mobile applications.
