[Applause]
your eyes a moment please because
They are listening to what he heard a
Sighted person walking on the street
auctioned the closed eyes and
just feel that they are behind bars
plus
in the world every seven seconds a
non-sighted person suffered an accident
many times minor accidents like
blows with a branch of a tree other
so serious that it can cause them
condensate death the work that
we have made the last four
years to be able to transmit yes they are
the next minutes
it is very likely that most
you have heard the word
echolocation maybe in a
documentary in a movie even in
a cartoon
echolocation is the
interpretation that an individual has
of your environment using the sounds
many animals in the wild are
mobilize and house only at night
even some of them have
developed stability and can
do it in totally dark places
without even a point of light
obviously they developed this by
need otherwise they would die of
ams
in this way it is like this little
bat uses echolocation
the night to detect this insect and
you can cover the dolphins well
bats and other animals have
stability your brain has the
ability to process information and
know how your environment is but
how does it work
in this case this little bat
is generating a peculiar sound that
is the one that is in tomato color and the
bounce of the sound on an object is the
of green color and what he hears the
bat in his right ear and in his
left ear is different is that
difference the one that lets you know where
the object is found
well in this case the bat does
a peculiar sound like then if
they want to practice it with me it’s like
when they are going to kiss and and put the
tongue the palate upstairs and do something
as well as if that sound like that the murcia
very good
or prefer to do it only is for
that nobody misinterprets then well is
a peculiar sound and so every animal
It has a sound but the most interesting
the sound is the bounce of the sound because
this is the one that allows you to interpret
fenton analyzing the environment
the animal creates a mental map then
what is the mental map mental map is
an analogy of what we see
with our eyes to what the animal
generates interpreting the sounds I go out
like this picture
obviously it does not have colors because it is
a sense of depth is
it’s just an imagination where
are the objects and well already
we talked a little about what is the
clyfc echolocation and as a function and
I ‘m going to tell you something that’s good to me
It seems incredible when I found out
that fascinated and know what
very peculiar stability
it is not unique to the animal kingdom if it is not
unique the animal kingdom
human beings we can develop
said many human beings have
developed and are considered as
super humans have probably seen
the movie later saw and then here in
This superhero movie is blind
and uses echolocation to know
how is your environment and exaggerated a
little of course it is not that it is so in
the reality but you get an idea of what
that treats echolocation that is
perceive the environment without the sounds
Now something very interesting and peculiar is
that most people who have
developed stability are blind
there are many blind people around the world
who have developed stability and but
because they are because of their brain
having no vision begins to take
more information from the other senses
the touch sharpens the pact sharpens
even and and the taste but the most
important what he hears then the
brain is receiving more information
with the objective of knowing how
find sanctity and stability
they develop eye on this
unconsciously develop them
unconsciously almost nobody of them
he knows that he is developing it in this
context presents Juan Luis
he is a blind person selected
for the history chain with for
participate as a superhuman because he has
developed stability to another level
Juan can drive a bike can
move through buildings and power
through the forest without
with a lot of obstacles
then it was considered as a
superhuman of course you have to take
in mind that he did it from ring and
he did it in an unconscious way
Now it is very important to know that
only they can develop it and that
it seems even more incredible because
all of us all of us
seeing this we can develop
stability if you do not know us
we hold constant training
we can develop the and we can
perceive the environment
If our eyes are obviously going to be
difficult because we see was going to be
complicated to train our brain
so that together united but
possible all with a workout
constant just like a
footballer or a pianist training a
couple of hours a day
if the blind will train daily
could bring the echolocation to
another level because there are very few who
have developed this
I’m sure that if Leon Messi does not
they would have practiced soccer all their
lifetime
able that now was not so famous
then in this context he presented them
to Daniel unjustly kiss in a talk
ted
where he tells the world how to
interpreted through the
echolocation is interesting because
he has schools around 40
countries where he teaches kids to his
students to develop stability and
It has gone very well but within the
context of echolocation exist
certain limitations and good I want
emphasize these limitations and
first there are about accessibility
of 39 million blind people in the
world and less than 0.1 percent is
subject to a type of training
probably because of the accessibility already
that nobody finds one of these
schools around the house by the
subject of costs since the 90th
hundred of this sector is in a
poor or vulnerable sector
so the issue of accessibility is
the main problem of the de of the
echolocation and how you can
develop now the second thing more
important is the subject
they do not feel restrained
shame even if it seems illogical
they do not like to walk and that
everybody listen
do not not prefer to go unnoticed and
the third is that the echolocation
can only be used in environments are
only saturated and what does it mean
this when a person does not see
is walking down the street try
use echolocation and it’s very
complex because when the sound is
mixed with the noise of the street and not
can interpret the bounce of it
now when they walk by these
places like the one we see in the photo what
consider it an extreme sport
in fact I have talked with many of
them and they say every time I go out to the
Street
I’m really doing sport
extreme for the level of risk that
they have with them with the objects and the and
the causes of accidents that exist in a
street is so high
so that’s why they consider it
as an extreme sport
in fact I do not know if they have seen a
person keep walking use the
cane and most objects the
can dictate with the cane but there
a lot of objects that do not
they have a base and that can cause them
an accident
the chest the face for example a rod
of a construction probably a
sign an umbrella of a cart and
an infinity of things and as a bridge
or a crossed cable that really
they can cause harm
in this context and in order to
solve these problems that
has echolocation an idea is born
a little over four years ago that is
win 6
then hannah is is a device
electronic that allows to solve these
small problems of the
echolocation then first
it works in the same way as commerce
the bat
only that in this case is the device
the one that generates the sound and generates a
sound at a high frequency and a sound
percutive very good that is the
specific, the most suitable for
bounce in a proper way in a
environment
It also has a warning system and it is
the most important that people
used in the environments that are are
numerically saturated
then this mode warned is that
simply the person is walking
‘there is no object a meter or less
the sun the device sounds or vibrates
warning him that there is an object
opposite and that you have to move to
On the other hand, I ‘m going to show you a video that
I love it because it serious as
cellular was something very natural happened does
a little over three weeks in a
test with some users
it happens that during we were in the
test and user said that he had
beaten
obviously very soft but we loved it
because we said right here so that
extraordinary how is the probability and
how it works then we did the same
path but now using the hies and
this is what he got
[Music]
good
[Music]
the people who did not touch her but she already
he felt and could
[Music]
right now cristina is going to be a
proof
let’s make him walk towards that
obstacle is not going to hit the head
and we hope that our device
works freely without the effect of avoiding
the blow avoid the blow but while it is
true as you could see this
object does not have a basis then with the
cane can not touch him and he walks
walk until it hits like them
commented sometimes they are small punches
but other times very strong blows
how important they are that nobody
You can put a price on an accident me
placé tell you that this project and
it’s been four years
now it’s on the market and as usual
as they commented was winner of an idea
to change the story and that
he asked still they think they are super
humans probably but have the
sure that each one of you
you can do thank you very much
the laws
