Apparatus and method for detecting device drop

An electronic device for detecting a drop event, the electronic device comprising:

• an inertial measurement unit (IMU) sensor configured to collect sensor data that indicates an angular velocity and a proper acceleration of the electronic device;
• at least memory storing instructions;
• and
• at least one processor configured to execute the instructions to:
• obtain the angular velocity and the proper acceleration of the electronic device based on the sensor data;
• obtain centripetal acceleration of the electronic device based on the angular velocity, principal moments of inertia of the electronic device, and position of the IMU sensor within the electronic device;
• based on an acceleration difference between the centripetal acceleration and the proper acceleration, determine whether the electronic device is in a fall state;
• and
• based on the electronic device being determined to be in the fall state, provide an analysis result of the drop event.

A non-transitory computer readable storage medium that stores instructions to be executed by at least one processor to perform a method for detecting a drop event of an electronic device, the method comprising:

• obtaining an angular velocity and a proper acceleration of the electronic device based on sensor data received from an inertial measurement unit (IMU) sensor of the electronic device;
• obtaining centripetal acceleration of the electronic device based on the angular velocity, principal moments of inertia of the electronic device, and position of the IMU sensor within the electronic device;
• based on an acceleration difference between the centripetal acceleration and the proper acceleration, determining whether the electronic device is in a fall state;
• and
• based on the electronic device being determined to be in the fall state, providing an analysis result of the drop event.
