Abstract

This paper describes a system which runs on a mobile phone that allows for the distribution of media packages to users with Bluetooth enabled camera phones. Users take photographss of specially designed posters and send them, using Bluetooth, to the system. An algorithm that enables the system to recognize the user images is developed, evaluated and modified using two rounds of user experiments. The final algorithm is found to correctly recognize the image photographed 87% of the time.
