Qt Quick application that integrates Compass information and OVI maps.
Compass is a Forum Nokia example application that teaches the use of a traditional compass and allows the user to determine the bearing to the desired location using Ovi maps. The main purpose of the example application is to demonstrate the use of the Maps and Navigation API.
Running the application
The application has two modes: Compass mode and Map mode.
In the Map mode you can view the map with your current position retrieved by GPS and indicated with a red circle. The radius of the red circle changes according to the GPS fix accuracy. The more accurate the fix, the smaller the circle; indicating your current location more precisely. The map can be panned by dragging it with a finger. The zoom level can be changed by pinching the map with two fingers. The GPS indicator in the upper left corner will iterate when the phone is trying to retrieve the GPS fix. The indicator is steady when the signal is received from the satellites. Tapping the GPS indicator will pan the map to the current location.
To navigate to a certain position in a map:
Switch to the Map mode, place the edge of the compass on the map so that it connects the current location with the desired destination, and turn the scale of the compass to the grid north.
Switch back to the Compass mode and turn around with the phone until the compass needle is positioned on top of the outlined orientating arrow. The desired bearing is now in front of you.
The following on / off settings adjust the behavior of the application:
Auto north in the map:
Automatically turn the scale of the compass to the grid north when the compass is rotated in the Map mode.
Bearing turnable in the Compass mode:
The turnability of the bearing can be prevented in the Compass mode. By setting the turnability off you can prevent accidential touch events which would affect to the navigation in the field. When turnability is enabled, the compass application can be used with a real paper map.
Prevent screensaver:
Prevents the screensaver from getting activated.
Satellite map:
Toggles between the map and the satellite.
Use sound in calibration:
Defines whether audio feedback is used during the calibration process.
Design considerations
Backup and restore
Application has support for Backup and Restore feature. When a backup is made from the applications, the settings of the Compass are included into the backup.
