Abstract

The present invention relates to the method for detecting falls by using relative barometric pressure signals, wherein comprising: the step of receiving signal, the step of processing, and the step of displaying, wherein the step of receiving signal comprises the signals from at least two barometric pressure sensors or the barometers attached to the positions at different or same height, wherein at least one barometric pressure sensor is attached on any position on the user's body and another barometric pressure sensor is attached on the reference position to be used as the reference at another position on the body at different height or any position in surroundings. When there is the postural transition or change in prefall and postfall activities, there is the change in the difference between the barometric pressure value from the barometric pressure sensor at any position to the barometric pressure value from the barometric pressure sensor at the reference position at least one pair when comparing values obtained from two sensors prior to the postural transition. For the step of processing, using the change in the barometric pressure values to indicate the change in the height of the device attached to the position for the detecting falls, activities and/or prefall activities, wherein the value obtained from the reference barometric pressure sensor causes the calculation of difference in the barometric pressure values to indicate the motion of the body more accurately as it could confute the change in the barometric pressure values altered based on time, place, and surroundings, wherein the step of processing includes the step of signal inference for the conversion of signals obtained from the step of receiving signals to the information for monitoring system for patients and elders.
