This thesis focus on understanding the possibilities of making invisible information visible, and how the concept can be achieved through mobile technology. We recognize that information possibly encompasses different temporal aspects. PhotoWorld seek to visualize past information, through presentation of photos in an urban environment. Subsequently, HouseView was implemented to visualize information with a future temporal foundation, by presenting architecture in-situ.

From our evaluation of both systems we learned valuable lessons: visualization through Augmented Reality requires thought into 3D registration, temporal diversity is a key element when presenting information and digital visualization is a good way of presenting temporal aspects of a context.
