Zusammenfassung
The advantages of paper-based maps have been
utilized in the field of mobile Augmented Reality (AR) in
the last few years. Traditional paper-based maps
provide high-resolution, large-scale information with
zero power consumption. There are numerous
implementations of magic lens interfaces that combine
high-resolution paper maps with dynamic handheld
displays. From an HCI perspective, the main challenge
of magic lens interfaces is that users have to switch
their attention between the magic lens and the
information in the background. In this paper, we
attempt to overcome this problem by using a
lightweight mobile camera projector unit to augment
the paper map directly with additional information. The
"Map Torchlight" is tracked over a paper map and can
precisely highlight points of interest, streets, and areas
to give directions or other guidance for interacting with
the map.
