Abstract
Provided are a fall detecting apparatus and method and an emergency aid system and method using the same. The fall detecting apparatus includes a storing unit configured to store fall data vectors; an angular velocity measuring unit configured to measure an angular velocity value; an acceleration measuring unit configured to measure an acceleration value; an acceleration extracting unit configured to extract a kinetic acceleration value and a gravitational acceleration value by filtering the acceleration value measured by the acceleration measuring unit; and a fall determining unit configured to convert the angular velocity value, which is measured by the angular velocity measuring unit, and the kinetic acceleration value and the gravitational acceleration value, which are extracted by the acceleration extracting unit, into a fall data vector, and determine a use's fall by comparing the converted fall data vector with the fall data vector stored in the storing unit.
