||People have always needed reminders, from tying a knot around the finger
to writing a to-do list. The types of reminders have changed with the addition
of modern technology, but the need is still the same. Technologies that use
temporal events can be seen in many places, such as electronic calendars that
remind users to go to a meeting a few minutes in advance.
With the recent release of Google's Android platform, developers now have
the opportunity to create applications that use spatial events, such as location reminders. This thesis explores how location reminders can be used, by
implementing a location based shopping list for the Android platform.
The primary and secondary use cases for a location based shopping list were
identified, and the primary use cases were thouroughly described by studying
how a paper shopping list works. Several user interface designs were described,
and the best design was chosen by comparing the different designs' strengths
A prototype that implemented the primary use cases was implemented and
tested on an HTC G1 smart phone. The tests included an acceptance test, unit
tests, a usability test, and a field test.
The results of the usability tests suggested that the prototype was easy to
use and user friendly, but inconclusive in whether the implemented prototype
was as fast to use as a paper shopping list.
Field testing showed that location reminders only worked well using GPS
and not with Cell-ID positioning on the G1 smart phone. The smart phone,
however, became unusable because the GPS used too much power.
The work done demonstrated that it is possible to implement applications that
use location reminders for the Android platform, but the G1 hardware is still
not capable to support location based applications.
