What Is Automatic Fall Alert Detection?
Auto fall alert detection systems make use of sensing mechanisms built into the pendant or bracelet that users of medical alarm systems wear.
The regular elderly personal emergency alert system includes a base console connected to a telephone line. An integral part is an emergency button, also referred to as the help button. It is worn by the elderly like a bracelet or necklace. This has a wireless transmitter that can be used to activate an alert call to the monitoring center once a fall occurs. With regular systems, it relies on the senior user pressing the button once a fall occurs and they can’t get up.
Alert Call Made Automatically When Fall Is Detected
For automated fall detection systems, the sensing mechanism will complete the job by activating an alert call automatically. For other sorts of emergencies, the senior can still press the button to be connected with a monitoring station professional.
How The Technology Works
The auto-detection based on the motion changes in the body position. According to the Philips Lifeline, their Auto Alert system can detect as much as 95% of falls that might occur. In general, an auto alert fall sensor works by utilizing the accelerometers and gyroscopes to analyze unusual misalignment in the body’s position to determine if a fall has occurred. Acceleration is measured by the accelerometer, while the angular momentum is measured by the gyroscope.
What Are the Advantages of the Auto Fall Detection?
User can’t manually press the emergency button after a fall – There are a lot of advantages that you can get from having this system. For children of users, they will have that peace of mind even if your elderly parent can’t react, someone can help them. User’s too, can be assured that if they fall and lose consciousness, they can get help.
Waterproof – The emergency button device is designed to be waterproof, so the elderly can still wear it where most falls occur – in the bathroom/shower.
In addition, systems like the Philips Lifeline has a necklace pendant with a smooth and comfortable design so it is attractive to wear them. The parts are replaceable in case of damage.

What Are the Disadvantages of the System?
While the automatic fall detection alert technology is very innovative and has been used for years already, it is only recently that this technology was incorporated into medical alert systems for home use. Theoretically, it sounds like a really good feature to include. So why aren’t all the best medical alert companies jumping on this new bandwagon? In fact, we believe that a number of the major life alert companies are already looking into it.
But there are a few disadvantages that seem to be holding back acceptance of this feature:
False alarms – Technologically at this time, sensing devices are not yet that sensitive to separate a lot of normal everyday routines from actual falls. There are instances that alarms come off without an actual fall. Along with detecting actual falls, there can be many false alarm instances that users need to deal with. These false alarms are very embarrassing and a waste of time to both the user and monitoring center staff. The good thing about it is that the system is continuously undergoing refinement.
Some Falls Not Detected – Unlike a traditional home medical alert where an SOS signal is sent once the button is pressed, the fall sensing technology of automatic fall detection buttons depends on several factors to determine that a fall has taken place. Not all falls are detected. There have been times where a senior has fallen and expected an emergency call to be made, but because they moved their bodies within the first X seconds, the sensor determined that the senior did not require emergency help, and an alarm call was not necessary.
Auto fall alert sensors typically require the senior who has fallen to hold still for 10 to 20 seconds after a fall to determine that an automated fall alarm call is justified. This not only delays the emergency alert calling, but it can also lead to unfulfilled expectations.
Sliding falls less detectable – There were cases of unreliability of the system, in addition to the notable false alarms, the auto detect device could have difficulty “sliding” falls, such as when the wearer slides down to the floor from their chair/wheelchair. In July 2014, a user on wheelchair fell and the alarm did not go off. Unfortunately, she passed away several hours later.
Higher cost – The automatic fall alarm system is more expensive compared to the regular manual counterparts. The Philips Lifeline Auto Alert system cost $45 and up a month to run. Users can find quality personal emergency response systems for quite a bit less.
False sense of security – Having an auto fall alert feature may allow users and their family members to feel more confident that users can get help when they need it. However, no system can detect 100% of falls. Having a system like this provides a false sense of security and cause additional confusion about how medical alert systems should work.
Given the current state of development, it seems that auto fall detection technology for personal emergency response systems have room for improvement. Adoption is growing. If your budget allows it, and you really want to try it out, we suggest looking into LifeStation, Medical Guardian or the Philips Lifeline Auto Alert system. Another choice is the Great Call Splash mobile GPS pendant that can work both in and out of the home.
If you do choose to get this for yourself or your parents, understand that it may not meet your level of expectations. Senior users may have to deal with unpleasant false alarms coming up. Also, not all falls are detected. The user should be aware that in some cases, they will still need to manually press the help button to activate an alarm call.
