Design and implementation of a fall detection monitor system with a voice interaction function for smartphones

In this paper a smartphone fall detection system featuring a three-axis accelerometer sensor with a voice interaction function is presented. The value, measured by the three-axis accelerometer sensor, is sent to the program. It is then calculated and compared to the fall characteristics. When a fall is detected, the voice function asks whether the user needs help. If the fall is not serious, the user can cancel this emergency notification by means of either the voice interaction function or the touch panel. Otherwise the smartphone would automatically send out an emergency signal to the help center to request assistance for the user.
