A technical review on the methodologies of fall detection

There is a high risk of falls in aged people due to acute and chronic health impairment. This causes injuries that affect their social life and independent living. Although various existing technologies focus on fall detection with individual sensors, the performance of these systems is still not satisfactory, as they suffer mainly from high false alarm rates. This paper includes a full description of detector technology, which range from accelerometers, pressure detectors, and camera to radar based detectors, as well as their incorporation into a full fall detection system. This describes advantages and disadvantages of several detector fall discovery methods with respect to point birth, bracket, experimental data set and performance. The primary topics that are not well addressed in the literature are the stoner stiffness, installation difficulty, and power usage of the systems. Finally, the study presents an initial framework for determining the technology for a certain script or position based on the deployment prerequisites.
