Virtual Orienteering – Find Your Way!
Virtual Orienteering is a game played outdoor inspired from Orienteering sport. The game concept is to use a GPS capable mobile device to replace the printed map and real control check-posts. There is no need to be someone involved in mounting control posts on the field because the GPS capable device will validate reaching the control points. All you need to do is to start playing on one of existing tracks, made by you or by your community friends.
You will not depend on a specific orienteering event because you can practice this game anytime, anywhere. Still, you’ll need a compass to guide the device and yourself on the track as not all the devices have digital compass sensor. The orienteering sport is getting a new level of fun as you can interact with lots of your community friends.
