Abstract: "Location-based mobile gaming
combines gameplay with physical ac
tivity. We have developed a game, O-
Mopsi, based on the concept of orienteering, which can
be played on mobile phones with GPS receiver and
Internet connection. In order to complete a game, a play
er must visit a set of targets that are photos chosen
from a user-generated geotagged database. Game crea
tion, management and live tracking can be done using
a web interface. The game was presented at an annual
international festival whic
h is aimed at introducing
science and technology to school children and the overa
ll feedback received from the players was positive. "
