Fall detection device and method for controlling thereof

A fall detection device comprising:

• at least one sensor which is attached to a user and senses a motion of the fall detection device in a plurality of coordinate axial directions comprising a first axial direction and a second axial direction perpendicular to the first axial direction;
• an output section which outputs fall information of the user;
• and
• a processor which:
• determines that the user falls down based on obtaining that acceleration in the first axial direction is changed from a positive value to a negative value, and acceleration in the second axial direction is lower than a first lower limit before impact occurs to the user while the acceleration in the first axial direction is changed from the positive value to the negative value based on the sensed motion of the fall detection device, and
• controls the output section to output the fall information that the user falls down.
