English abstract:
The exploration of the immediate surroundings through mobile location-
aware devices is starting to become an everyday urban activity. Due to the
increasing amount of available geo-referenced information, advanced
viewing and filtering techniques need to be investigated as a complemen-
tation to simple present-day 2D-map presentations. This article examines
both well-established techniques (2D map, list view, category view) and
advanced concepts (3D map, tag cloud) regarding their support of mobile
urban exploration. In a field study, 26 participants used an experimental
multi-view prototype for viewing and filtering tasks on a route through an
urban environment. The results show that content-based views may provide
similarly good support for viewing the content as spatial interfaces.
Furthermore, the experiment provides evidence that the advantages of
content-based filtering techniques are increasingly preferred to spatial ones
in regard to the amount of available information.
