very much fascinated by Star Wars,
is this notion of the Force,
era a noción da Forza.
all people and all objects
todas as persoas e todas as cousas
that you can't even see.
que nin sequera podes ver.
I would be sitting at home,
trying to feel the Force,
and started working on wireless signals.
nos sinais sen fíos.
or cellular systems,
ou os sistemas móbiles.
kept nagging me,
they are like the Force."
son coma a Forza."
they travel through space,
viaxan a través do espazo,
and walls and occlusions,
because our bodies are full of water,
que está cheo de auga
just sense these minute reflections,
esas ínfimas reflexións,
that I cannot see.
que non podo ver.
en construír ese aparello
on building such a device,
some of our early results.
algúns dos nosos primeiros resultados.
in the other office, behind the wall,
na outra oficina, detrás do muro,
to monitor him as he moves.
using wireless signals.
usando sinais sen fíos.
is tracking his movements very accurately,
os seus movementos con moita precisión,
with the surrounding wireless signals.
interactúa cos sinais sen fíos do arredor.
that we can sense people
que poidamos sentir a xente
any wearables, through walls,
a través dos muros.
to think about is radar.
que me vén ao maxín é o radar.
have seen this picture.
comes back to you,
wireless power at somebody.
disparar sen máis unha carga eléctrica.
like if they were in a microwave.
coma se estivese nun microondas.
de apañarvos con sinais moi febles
to deal with very weak signals,
has to be very sensitive.
debe ser moi sensíbel.
o ceo está baleiro
unlike the sky, where it's empty --
que podes cachar aí arriba.
that you can catch there.
and people there are.
hai aquí.
not only reflects off the person,
o sinal non só se reflicte na persoa,
off the floor, the ceiling,
e tamén no chan, no teito,
off me and then off you,
se reflicte en ti e en min,
then off the floor.
a toda esa enleada.
have evolved a lot,
evolucionaron moito
became much more powerful,
very sensitive radios
radios máis sensíbeis
febles e ínfimos.
da aprendizaxe automática
of machine learning recently,
nese campo recentemente,
machine-learning models
modelos de máquinas intelixentes
and interpret them
os sinais wifi e interpretalos
in the environment.
the radio is like the ear of our device
a radio é coma o ouvido do noso aparello
is like the brain,
a very powerful device.
mediante sinais sen fíos?
using wireless signals?
very dear to my heart,
é algo moi prezado para min
on some physiological signal
nun sinal fisiolóxico
podemos capturar o sono
sees him as he walks to bed,
e ségueo mentres vai para a cama,
is what people call actigraphy.
é o que chamamos actigrafía.
that we can actually get sleep
chegar a ver o sono
the change in the brain waves
das ondas cerebrais
that as we go to sleep,
sen dúbida, que cando imos durmir
and we enter different stages:
e entramos en diferentes fases:
and REM, or rapid eye movement.
ou movementos oculares rápidos.
related to sleep disorders,
con desordes do sono
to various diseases.
are associated with depression.
están relacionadas coa depresión.
are associated with Alzheimer's.
están asociados co alzhéimer.
enviaríamos a persoa ao hospital,
to the hospital,
electrodes on their head,
that I can do the same thing
facer exactamente o mesmo
on the person's body?
wireless signal,
de sinais sen fíos moi baixos
throughout the night.
ao longo da noite.
when this person is dreaming.
cando unha persoa está soñando.
mentres estades aí sentados
while you are sitting like that,
staying at a steady level
mantense nun nivel estábel
and show you a live demo.
e facer unha demostración en directo
to monitor Zach's breathing.
para controlar a súa respiración.
that you see here is the device,
é o dispositivo.
in the video with the other guy,
ca no vídeo co outro tipo
his inhale-exhale motion.
o movemento inspira-expira.
are Zach breathing.
é Zach respirando.
at a steady level,
temos este instrumento
physiological signals for you,
tantos signos fisiolóxicos
about this device
without any wearables,
to change his behavior
que cambie os seus hábitos
or charge anything special.
more information about their patients,
sobre os seus pacientes,
in chronic diseases,
nas enfermidades crónicas
and even depression.
e incluso, na depresión.
are very important.
son moi importantes.
of health care in the US
about chronic diseases
sobre estas enfermidades
to the hospital and the emergency room,
ás urxencias do hospital
chronic disease patients in their home,
aos pacientes crónicos
heartbeat, mobility, sleep --
no pulso, na mobilidade ou o sono.
before they occur
antes de que ocorran
with multiple doctors
con múltiples doutores
with many patients.
con moitos pacientes.
with patients that have COPD,
on improving their life,
en mellorar a súa vida,
Star Wars e a Forza.
and the Force in Star Wars,
very much fascinated,
health care with this new force.
a asistencia sanitaria.
we deployed is actually my aunt.
é de feito a miña tía
in the audience
loved ones who have chronic diseases.
con enfermidades crónicas.
that has a chronic disease patient,
sitting in the background
nalgún curruncho
of this chronic disease patient,
a saúde do paciente crónico.
dos signos fisiolóxicos
in the physiological signal
as we know it today,
tal e como a coñecemos,
chronic diseases
sobre as enfermidades crónicas
like the ethical framework around this?
o marco ético en todo isto?
this technology from being used
que esta tecnoloxía sexa usada
types of applications?
digamos menos positivos?
a very important question, of course,
que é unha cuestión importante
about the Dark Side of the Force?
o lado escuro da Forza?
from trying to use this device
sen o seu consentimento.
by doing certain movements,
mediante certos movementos
who you are asking the device to monitor.
iniciar a monitorización.
that we integrate to prevent misuse,
para previr un mal uso
for policy, like everything else,
coma en todo,
we can control any misuse.
poidamos controlar o abuso.
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.
