APPARATUS AND METHOD FOR DETECTING HEADING CHANGE IN MOBILE TERMINAL

摘要

An apparatus and a method for detecting a heading change of a navigating body to which a mobile terminal has been attached are provided. The mobile terminal includes at least one measure unit and a change vector calculator. The at least one measure unit measures at least one of an acceleration of gravity component vector and a rotational axis component vector, with respect to a rotation of the navigating body, on a terminal coordinate system that is fixed in the mobile terminal. The change vector calculator calculates a horizontal heading change vector and a vertical heading change vector based on at least one of the acceleration of gravity component vector and the rotational axis component vector.
