Claim 14:
15. An operation method of an electronic device, the method comprising:
acquiring acceleration sensing data from an inertia sensor included in the electronic device, wherein the acceleration sensing data acquired by the inertia sensor includes a local frame value corresponding to a relative coordinate system, and atmospheric pressure sensing data from an atmospheric pressure sensor included in the electronic device;
converting the acceleration sensing data from a local frame to a navigation frame;
extracting a value less than 0, as a gravity direction feature from the acceleration sensing data converted into the navigation frame;
sensing occurrence of movement of the electronic device with a direction of gravity, with reference to a peak of the gravity direction feature;
sensing whether the electronic device has fallen based on the acceleration sensing data and the atmospheric pressure sensing data; performing a first process for determining a fall accident based on a gravity-free section and a second process for determining a fall accident based on a difference value between gravity direction features after an impact timepoint, when it is determined that the electronic device has fallen; and
determining a user has fallen, when it is determined that the fall accident has happened based on the first process and the second process.
