is this notion of the Force,
all people and all objects
összekötő energia,
akiket még csak nem is látunk.
that you can't even see.
I would be sitting at home,
trying to feel the Force,
igyekeztem megérezni az Erőt.
and started working on wireless signals.
és rádiójelekkel kezdtem foglalkozni.
or cellular systems,
kept nagging me,
they are like the Force."
olyanok, mint az Erő!"
they travel through space,
and walls and occlusions,
because our bodies are full of water,
mert testünk vízzel van teli,
just sense these minute reflections,
ezeket az apró visszaverődéseket,
that I cannot see.
látható embereket érzékelni.
on building such a device,
ilyen készülék megépítéséhez,
some of our early results.
néhány kezdeti eredményünket.
in the other office, behind the wall,
a szomszéd szobába, a falon túlra,
to monitor him as he moves.
using wireless signals.

is tracking his movements very accurately,
with the surrounding wireless signals.
a környező jelekre hat.
that we can sense people
és nyomon követése falon át,
any wearables, through walls,
to think about is radar.
a radar juthat eszükbe.
have seen this picture.
comes back to you,
visszaverődve visszaérkezik,
wireless power at somebody.
valakire rádiósugárzást bocsátani.
like if they were in a microwave.
to deal with very weak signals,
has to be very sensitive.
érzékenynek kell lennie.
unlike the sky, where it's empty --
és csak egyetlen gépet kell befogni,
that you can catch there.
and people there are.
not only reflects off the person,
nemcsak emberekről verődik vissza,
off the floor, the ceiling,
visszaverődéseket kapunk,
off me and then off you,
majd a padlóról verődik vissza.
then off the floor.
have evolved a lot,
became much more powerful,
teljesítményre lett képes,
very sensitive radios
jeleket érzékelő rádiót építhetünk.

történtek a gépi tanulásban,
machine-learning models

ami a környezetükben történik.
the radio is like the ear of our device
is like the brain,
a very powerful device.
using wireless signals?
az emberekkel kapcsolatban?
very dear to my heart,
on some physiological signal
élettani jelen kezdünk dolgozni,
sees him as he walks to bed,
látja, amint odamegy az ágyhoz,
is what people call actigraphy.
aktigráfiával rögzítjük,
that we can actually get sleep
the change in the brain waves
that as we go to sleep,
hogy mikor aludni térünk,
and we enter different stages:
és más-más fázisokba jutunk:
and REM, or rapid eye movement.
és a REM, a gyors szemmozgású.
related to sleep disorders,
to various diseases.
are associated with depression.
depresszióra utalnak,
are associated with Alzheimer's.
to the hospital,
electrodes on their head,
that I can do the same thing
on the person's body?
bármiféle elektródák nélkül?
wireless signal,
rádiójeleket sugároz,
throughout the night.
az éjszakai alvásfázisok jellemzőit.
when this person is dreaming.
while you are sitting like that,
staying at a steady level
and show you a live demo.
és élő felvételt mutatok.
to monitor Zach's breathing.
fogjuk figyelni a készülékkel.
that you see here is the device,
in the video with the other guy,
amit a videón lévő másik pasival:
his inhale-exhale motion.
are Zach breathing.
at a steady level,
physiological signals for you,
about this device
without any wearables,
to change his behavior
or charge anything special.
vagy bármit is feltöltenie.
more information about their patients,
tudni a pácienseikről,
in chronic diseases,
légúti betegségre, a COPD-ra,
and even depression.
de még a depresszióra is.
are very important.
of health care in the US
about chronic diseases
to the hospital and the emergency room,
chronic disease patients in their home,
idült betegeinket,
heartbeat, mobility, sleep --
mozgásuk, alvásuk módosulását
before they occur
még bekövetkezte előtt;
with multiple doctors
with many patients.
telepítettük a készüléket.
with patients that have COPD,
on improving their life,
dolgozunk az orvosokkal.
and the Force in Star Wars,
a Csillagok háborújába és az Erőbe.
very much fascinated,
következő részét.
health care with this new force.
meg lehet változtatni a gyógyítást.
we deployed is actually my aunt.
in the audience
loved ones who have chronic diseases.
hozzátartozójának van idült betegsége.
that has a chronic disease patient,
sitting in the background
of this chronic disease patient,
légzését, egészségét,
in the physiological signal
as we know it today,
chronic diseases
like the ethical framework around this?
this technology from being used
types of applications?
kevésbé helyes alkalmazását?
a very important question, of course,
about the Dark Side of the Force?
from trying to use this device
nyomon követésére.
by doing certain movements,
bizonyítékot fog követelni,
who you are asking the device to monitor.
igénylik a készüléktől.
that we integrate to prevent misuse,
for policy, like everything else,
szabályai is, mint minden másnak,
we can control any misuse.
bármi visszaélést megfékezhetünk.
ABOUT THE SPEAKER
Dina Katabi - TechnologistDina Katabi investigates how AI can make wireless devices sense human motion and vital signs.
Why you should listen
Dina Katabi designs new wireless devices that use machine learning to sense people through walls and occlusions. Her devices look like a Wi-Fi box. They transmit a low-power wireless signal and capture its reflections as it bounces off people and objects. They analyze those reflections to learn how people walk, measure their gait and detect elderly falls. The device can also measure a person's breathing, heart rate and sleep quality using wireless signals, without any sensor on the person's body. Katabi is working with medical doctors to use her technology to detect health emergencies and provide a better understanding of chronic diseases such as Alzheimer's and Parkinson's.
Katabi is the Andrew & Erna Viterbi Professor of Electrical Engineering and Computer Science at MIT. She is also the director of the MIT's Center for Wireless Networks and Mobile Computing, a member of the National Academy of Engineering and a recipient of the MacArthur Fellowship. Her research has been recognized by the ACM Prize in Computing, the ACM Grace Murray Hopper Award, the SIGCOMM Test-of-Time Award, the IEEE William R. Bennett prize, the Faculty Research Innovation Fellowship, a Sloan Fellowship and multiple best paper awards. Several startups have been spun out of her lab, such as PiCharging and Emerald.
