Development of a Wearable-Sensor-Based Fall Detection System

Table 1

Test results for four kinds of falling and five kinds of ADL.

Motion type	Alarm times/test times
	Proposed design	Acceleration threshold based design
Forward fall	60/60	59/60
Backward fall	56/60	54/60
Leftward fall	58/60	52/60
Rightward fall	59/60	55/60
Walking	0/60	4/60
Jumping	0/60	11/60
Squatting	0/60	0/60
Sitting	0/60	9/60
Resting	5/60	10/60
