Electronic device, computer program product and method of operating built-in compass
First Claim
1. A method of operating a built-in compass of an electronic device, the method comprising:
- setting a horizontal condition required for the built-in compass, the horizontal condition indicating admissible values of tilt angle of the electronic device;
detecting activation of a navigation application on the basis of a gesture input of an input device;
measuring a tilt angle of the electronic device when activation of the navigation application is detected;
comparing the measured tilt angle with the horizontal condition for the built-in compass;
calculating a compass direction when, on the basis of the comparison, it is detected that the electronic device meets the horizontal condition required by the built-in compass; and
giving at least one of a tactile indication and an audible indication when the calculated compass direction is available.

Abstract
There is provided an electronic device having a built-in compass, comprising: a processing unit for controlling functions of the electronic device; an input device for giving control commands; an acceleration sensor for measuring tilt angle of the electronic device. The processing unit is configured to set a horizontal condition required for the built-in compass, the horizontal condition indicating admissible values of tilt angle of the electronic device, to detect activation of a navigation application on the basis of the input device, to send a control command to the acceleration sensor for measuring a tilt angle of the electronic device when activation of the navigation application is detected, to compare the measured tilt angle with the horizontal condition for the built-in compass, and to calculate a compass direction when, on the basis of the comparison, it is detected that the electronic device meets the horizontal condition required.
