A Rapid Prototyping Platform for Mobile Phone Based Services on Retail Products The mobile phone is set to change the way we shop in the future. Using its built-in camera to recognize the standard barcode present on virtually every product world-wide, consumers will be able to simply scan a product and access product-related information and personalized services while they are in the store. The creation of such mobilephone based applications that provide services and information to real-world objects is currently very attractive: for prototypes, technology demos, or user studies. But even though many components of such applications and prototypes are recurring, the creation of even simple applications currently requires a lot of time and know-how - both limiting the progress and development of new mobile-phone based applications and ideas. This document introduces a rapid prototyping platform that allows for the creation of easy-to-use mobile-phone based applications based on the robust recognition of 1D barcodes on retail products within minutes, without any sophisticated phone-programming know-how.
