There are a growing number of mobile phones being used in developing contexts, such as Africa. A large percentage of these phones have the capability to take photographs and transmit them freely using Bluetooth. In order to provide people with media on their mobile phones public displays are becoming more common. Three problems with current public displays – cost, security and mobility – are discussed and system proposed that uses a mobile phone as a server. Media is displayed on specially designed paper posters, which users can photograph using their mobile phones. The resulting photographs are sent, via Bluetooth, to the server, which analyses them in order to locate a specially designed barcode, representing the media, which is then decoded and the requisite media returned to the user. Two barcoding systems are tested in laboratory conditions, and a binary system is found to perform best. The system is then deployed on a campus transportation system to test the effects of motion. The results show that the system is not yet ready for deployment on moving transport.
