Ecolocalización/ Echolocation | Diego Aguinsaca | TEDxCuenca


[Music]
[Applause]
his eyes because one moment please
They are listening to what he heard a
sighted person walking on the street
He auctioned having closed eyes and
just they feel they are behind bars
plus
in the world every seven seconds , a
blind person had an accident
often minor accidents
blows with a branch of a tree other
so severe that can cause them
Condensate death the work
we have made the last four
years to convey what are yes
the following minutes
It is very likely that most
you have heard the word
echolocation perhaps in a
documentary film even
a cartoon
echolocation is the
interpretation that an individual
their environment using sound
many animals in nature
mobilize and home only at night
even some of them have
developed stability and can
do it in completely dark places
without even a point of light
this obviously developed
need otherwise die of
ams
thus it is as this small
bat uses echolocation
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 is your environment but
how does it work
In this case this small bat
It is generating a peculiar sound
It is the color that is tomato and
bounce sound on an object is the
green and listening to
bat in his right ear and his
left ear is different is that
difference that lets you know where
the object is
good in this case the bat ago
then a peculiar sound as if
want to practice with me it is like
when they go to kiss and and put the
tongue palate above and do something
and if that sound like Murcia
very well
or whether you prefer to do is just to
well then nobody is misunderstood
a peculiar sound so each animal
It has a sound but more interesting
the sound is the sound bounce because
this is the one that lets you play
fenton analyzing the environment
the animal then make a mental map
what is the mind map mind map is
an analogy of what we see
with our eyes to what the animal
interpreting generates sounds I leave
Like this image
obviously no color because it is
a sense of depth is
it is only an imagination where
objects are well and
We’ve talked a bit about what the
CLyFC echolocation and as a function and
I’ll tell you something good to me
It seems incredible when I found out
that fascinated and know what
very peculiar stability
It is not unique in the animal kingdom if not
only the animal kingdom
humans can develop
It said many human beings have
developed and are considered as
super humans have probably seen
and later he saw the film because here in
This superhero movie is blind
and uses echolocation to know
how your environment and overdid
little course that is not so in
reality but gives an idea of what
dealing echolocation is
perceive the environment without sound
Now something very interesting and quirky is
most people have
developed stability are blind
there are many blind around the world
they have developed stability and but
because they is q your brain
having no vision begins to take
more information other senses
touch the pact sharpens sharpens
yy even taste but more
important what you hear then the
receptando brain goes more information
in order to know how
and stability is santón
develop eye on this
unconsciously develop
unconsciously almost none of them
He knows that is developing in this
Juan Luis context presents
he is a blind person selected
history with the chain to
participate as a superhuman because it has
developed stability to another level
John can handle bike can
move through buildings and power
through the woods
with lots of obstacles
then it was considered a
Superhuman course be taken
note that he did from ring
because he did unconsciously
now very important is to know that no
only they can develop and that the
I find even more amazing because
all of us all who we are
Seeing this we can develop
stability if not we
we subject to constant training
We can develop and can
perceive the environment
if our eyes obviously going to be
difficult because we see would be
complicated train our brain
so that together united but
with all possible training
constant as it does a
football player or a pianist training a
couple of hours a day
If the blind will train daily
echolocation could lead to
another level because they are very few
They have developed this
I’m sure if Lionel Messi not
they had practiced football all his
lifetime
able now he was not so famous
then in this context he presented them
Daniel kiss unfairly in a talk
ted
where he tells the world as how
interprets through
echolocation is interesting because
he has about 40 schools
countries in which teaches children their
students develop stability and
as it has done very well but in the
context of echolocation there
certain limitations and want good
emphasize these limitations and
first there are about accessibility
39 million people are blind in
World and less than 0.1 percent is
subject to a type of training
probably because of the accessibility and
no one finds one of these
schools around the house by the
issue of costs since 90
percent of this sector is in a
poor or vulnerable sector
then the issue of accessibility is
the main problem of the of the
echolocation and how you can
develop now the second thing
important is the issue
that they are self – conscious do not feel
Shame may seem illogical
They do not like to walk and
everybody listen
They prefer not not go unnoticed and
The third is that echolocation
You can only be used in environments are
only saturated and what it means
this that when a person blind
You are walking down the street trying
to use echolocation and is very
complex because when the sound
mixed with street noise and not
You can interpret rebound same
Now when they walk by these
places like you see in the picture it
considered as an extreme sport
in fact I have talked with many of
them and say every time I go to the
Street
really I am doing sports
end by the level of risk
They have with the objects and and
the causes of accidents there in a
it is extremely high street
then why is it considered
as an extreme sport
in fact I do not know if they have seen as a
keep walking person using the
staff and most of the objects
they can dictate the stick but there
a lot of objects that do not
They have a base and can cause them
an accident
chest face such a rod
a construction probably a
umbrella sign a cart and
an infinity of things and as a bridge
or a cable crossed that you truly
They can do harm
in this context and in order to
solve these problems that they
echolocation has an idea born
a little over four years ago it
win 6
hannah then is a device
mail that can solve these
small problems
echolocation then first
It works just as trade
the bat
but in this case the device
which it generates sound and generates a
a high frequency sound and sound
percussive very good the
specifically the most suitable for
rebound in a suitable manner on a
environment
also it has a warning system and
the most important people
They used in environments that are are
numerically saturated
then this mode is warned
just the person is walking
‘there is an object at one meter or less
the sun the device rings or vibrates
warning him that there is an object
front and you have to scroll
other side I’ll show you a video
I love it because it serious as
cell was a very natural thing happened ago
a little more than three weeks in a
testing with some users
It happens during we were in the
testing and user said he had
beaten
obviously very soft but we loved
because we said right here or whether it
extraordinary as is the likelihood and
how it works then did the same
path but now using the HIES and
this is what he got
[Music]
good
[Music]
people who did not touch but already
he felt he could
[Music]
cristina right now right now will be a
proof
we will make walk toward that
obstacle is not going to hit the head
and we hope that our device
It operates freely without preventing effect
the coup avoid the blow but if it is
true as you could see this
object has a base then with
You can not touch cane and walking
walk until it hits like them
He said sometimes are small bumps
but sometimes very heavy blows
The important thing about them that nobody
You can put a price on an accident me
placé tell you that this project and
for four years
now hits the market and as common
as they were commented winner of an idea
to change history and they
He asked still believe they are super
but humans probably have the
sure that each of you
You can do thank you very much
