With its mixing of real and virtual, Augmented Reality (AR) is a technology that has attracted
lots of attention from the science community and is seen as a perfect way to visualize contextrelated
information. Computer generated graphics is presented to the user overlaid and registered
with the real world and hence augmenting it. Promising intelligence amplification and higher
productivity, AR has been intensively researched over several decades but has yet to reach a
broad audience.
This thesis presents efforts in bringing Augmented Reality to mobile phones and thus to the
general public. Implementing technologies on limited devices, such as mobile phones, poses
a number of challenges that differ from traditional research directions. These include: limited
computational resources with little or no possibility to upgrade or add hardware, limited input
and output capabilities for interactive 3D graphics. The research presented in this thesis addresses
these challenges and makes contributions in the following areas:
