III. EASYTRACKER IN ACTION
A. Basic functionality enhanced with privacy filters
Common to all similar applications, the main
functionality of EasyTracker is to record a track and
visualize it in real time on a user-selected map. Thereby it
stores the geographical coordinates on a local database and it
is able to calculate useful statistics (total distance travelled,
average speed, etc.). Using the device orientation sensor, the
real heading can be calculated and displayed on a map and
on a built-in compass. The user has also the options to take
photos or set places (point of interests - POI) and associate
them to geographical coordinates, create notations to each
part of a track, view a stored track on a map or export a
saved track in a geographical file following one of many
well-known data formats like GPX, KML and CSV.
