An Analysis on the Feasibility of a Low-cost Fall Detection System
Samuel Caryabudi, Atar Fuady Babgei, Achmad Arifin · 2020
There are various fall detection algorithms that have been developed as the solution to the increase on the risk of fall on elderly. A fall detection system which is low-cost is certainly favored, but that pose another question on whether the system is accurate enough by using low-cost components. This paper will discuss the analysis on the feasibility of a threshold-based fall detection system that was realized with ADXL 345 sensor, which is considered as a low-cost accelerometer sensor. A simulated fall study and simulated Activities of Daily Living (ADL) study was conducted so that the accuracy of the realized system can be known. The result of this experimental study shows that the realized system has a satisfactory accuracy comparable to other systems which use more advanced sensor(s), but further study which involves elderly as subjects is needed to give a more accurate insight about the accuracy of the system.
