It has been predicted that about one billion mobile phones will be sold in the
world in year 2007 ñ and that 90% of these phones will be equipped with a
digital camera. So the emerging camera phone technology will be in everyday
use for most people in the near future and this development will offer great
prospects for the services based on these technology. Two of the most potential
application areas of this multi-billion dollar industry of the future are the
publication and packaging products, because these items are extensively used in
everybodyís everyday life. In this project the technologies and the operational
environment, in which the new camera phone based applications are developed
has been studied. Demonstrators where 2D bar codes can be utilized in
information transfer of packages have been built, and a software enabling
detection of colour-changing codes has been developed.
