Intelligent Fall Detection Using TI mmWave Sensors


Hi. Today we’ll be showing how TI’s
60 gigahertz millimeter wave sensors provide
sensing capabilities that allow in-home
monitoring systems to detect potential falls. Home monitoring systems
with fall detection can benefit many people, such
as senior citizens or those with disabilities. For instance, nearly 1/3 of
seniors living at home fall at least once every year, and
nearly half of all seniors who fall cannot get up on their own. Here, we are showing
our detecting human falls and stands demo. TI millimeter wave sensors
provide range, velocity, and angle data, which are used
to create a rich 3D point cloud representation of
people in a scene. Notice how the point cloud
can represent individuals without any sort of contact
and without revealing any identifiable
characteristics, making it suitable for installation
in sensitive areas, like bedrooms or bathrooms. As you can see from the
GUI, the point cloud indicates stance by
the color and shape of the figure changing. A person’s standing
is typically shown as a long, thin cluster, while
a person sitting is a round cluster. The color illustrates
height by a person standing being represented as yellow,
orange, and green points and lying down as
darker blue points. When a person falls, their
point cloud shape changes from long and thin
to short and wide, indicating standing to laying. In an elderly
monitoring scenario, this point cloud can
be used to determine if a person has fallen and then
send an alert to a caregiver. Advanced fall
detection technology using millimeter wave sensors
does not require someone to wear a physical monitor,
rely on the use of a camera to detect when a
fall occurs, and can be used for monitoring
multiple individuals within an area at once. In addition, TI
millimeter wave sensing enables high-accuracy
fall detection in all lighting and
environmental conditions. Learn more about how to
