Abstract
A system and method for attitude correction is provided. An acceleration and an attitude of an electronic device are detected. A period of time where a velocity of the electronic device at the beginning of the period of time and a velocity of the electronic device at the end of the period of time are equal is identified. An attitude correction is calculated based on the identified period of time and the detected acceleration of the electronic device during the period of time. The detected attitude of the electronic device is corrected with the calculated attitude correction.
