typical VR experience but it's not

play01:10

vario has created a headset which is

play01:12

changing how people interact with

play01:14

virtual and computer-generated Worlds by

play01:17

changing how their brains engage with

play01:19

them here in this example we have a

play01:43

feels realistic

play01:45

we design Optics and displays that make

play01:49

it possible to see in the same

play01:51

play02:01

photorealism is one of the first steps

play02:04

towards convincing our brains that

computer interfaces or bcis

play02:18

the vario headset uses hardware and

play02:22

software from a company called open BCI

play02:24

a BCA is a brain computer interface so

play02:28

it's essentially a way for the brain to

play02:31

directly interface with computers by

play02:33

reading out signals from the brain

play02:35

[Music]

play02:38

the term brain computer interface was

play02:41

coined in the 1970s in California the

play02:44

aim was to control external objects

play02:46

using signals from the brain but it's

play02:48

only within the last 20 years that

play02:50

researchers have started to pull this

play02:52

off turn right

play02:56

and Fire

play03:01

today there are two kinds of bcis the

play03:05

first type are called non-invasive and

play03:08

can take the form of portable devices

play03:10

using non-invasive ways of reading out

play03:12

brain activity those signals are

play03:14

directly translated into ways of

play03:19

video game or it's a robotic arm or any

play03:22

sort of machine

play03:24

[Music]

play03:26

to make computers better at reading

play03:28

brain signals scientists need to get

play03:31

better at understanding the brain

play03:33

you can't put a BCA on think to yourself

play03:36

do I want to eat you know fried chicken

play03:39

or a sandwich or a salad for lunch and

play03:42

then think of it and then order it

play03:44

online you don't have clear brain

play03:46

regions for fried chicken versus salad

play03:48

in the brain

play03:50

if we know what the brain activity is

play03:51

that we're looking for in the brain

play03:53

region then we can use that signal to

play03:55

control a BCI

play03:56

[Music]

play04:01

improving the understanding of the brain

play04:03

could lead to the type of BCI featured

play04:06

in the film Ready Player One

play04:09

set in 2045 it shows much of humanity

play04:12

Escaping The Real World by using

play04:14

headsets which fully immerse their

play04:16

brains in the Oasis a near perfect

play04:19

virtual reality simulation

play04:22

getting the design of non-invasive bci's

play04:25

right is vital to fulfilling their

play04:27

potential

play04:28

some find devices like headsets

play04:30

impractical and bulky

play04:32

[Music]

play04:35

but scientists are bringing designs down

play04:37

to size on top you can see one of the

play04:40

early prototypes of attention view

play04:42

glasses which have a sensors on the back

play04:45

of the ears Dr Natalia cosmina is a

play04:48

technologist at MIT who is working on a

play04:51

series of new designs in conjunction

play04:52

with NASA we have a project with NASA

play04:56

about optimizing performance of

play04:59

astronauts

play05:01

the project is using this technology to

play05:03

read the brain activity of astronauts on

play05:06

missions to the International Space

play05:07

Station in order to monitor their health

play05:10

and performance so it's a suite of

play05:14

different variable Wireless

play05:17

sense in devices that can pick up brain

play05:20

activity eye movements and those can be

play05:24

put in the form factor of a pair of

play05:25

glasses

play05:29

we're gonna try on a pair of attentive

play05:33

view glasses so we can pick up the brain

play05:36

activity using these electrodes the

play05:38

attentive view glasses allow someone to

play05:40

answer questions by simply thinking of

play05:42

the answer

play05:43

the computer is able to understand their

play05:45

answer by recording their brain waves so

play05:48

what Kareem will need to do using only

play05:51

his brain activity to give an answer to

play05:53

this question so do you like it here

play05:57

yes

play05:59

okay did we get it right I assume yes

play06:02

it's a technology that offers great

play06:04

promise on Earth as well as in space for

play06:07

example for people suffering from

play06:09

neurogenerative disorders like ALS which

play06:12

causes a loss in the ability to

play06:14

communicate what we actually are doing

play06:16

we are providing them with this basic

play06:18

education the caregiver can ask a

play06:20

question to the patient and the patient

play06:23

can respond yes no

play06:26

[Music]

play06:27

these devices also have the potential to

play06:30

physically alter the brain and change

play06:32

how it works

play06:35

try not to think

play06:39

to think of and just rest your head for

play06:41

10 seconds okay okay Professor suck Lee

play06:44

Liu is a neuroscientist who has been

play06:46

working in this field for over 10 years

play06:49

over time if you train or practice with

play06:51

a BCI a lot you can actually see changes

play06:54

in both the brain activity patterns that

play06:57

people have and in the brain structures

play06:59

using a BCA can not only replace or

play07:02

serve as a compensatory role for

play07:04

replacing function but it can actually

play07:06

also help to rehabilitate or restore

play07:09

brain networks and Pathways and it's

play07:13

essentially like a like a brain training

play07:15

sort of tool

play07:17

one day the world may wake up to the

play07:19

reality of another kind of brain

play07:21

computer interface

play07:25

evasive kind when the Matrix will no

play07:28

longer be just a Hollywood dream

play07:30

invasive bcis promise the future merger

play07:33

of brains and computers through surgical

play07:35

implants

play07:37

it's early days for this technology and

play07:39

so far testing has mostly been done on

play07:42

animals rather than humans

play07:43

[Music]

play07:45

like this monkey pager pager simply

play07:49

thinks about moving his hand up or down

play07:52

with electrodes surgically inserted into

play07:54

his brain he is able to play the game

play07:56

pong simply by thinking about moving his

play07:58

hand up or down and sending brain

play08:01

signals to the computer

play08:03

the experiment was conducted by Elon

play08:05

musk's company neurolink

play08:08

neurolink says its ultimate aim is to

play08:10

improve the lives of humans with

play08:12

impaired abilities

play08:14

however its experiments have proved

play08:16

controversial protesters lining up

play08:19

calling for neural links animal testing

play08:21

labs to be shut down

play08:22

the company says it has euthanized eight

play08:25

monkeys but insists it has followed the

play08:27

law at all times

play08:32

invasive bcis can also pose ethical and

play08:34

health risks for humans so they actually

play08:37

have to cut your skull open and then

play08:39

implant an electrode and then put the

play08:41

skull back on

play08:42

despite this many consider these

play08:45

implants to be the most promising path

play08:47

to removing the gap between the virtual

play08:49

and Real Worlds

play08:50

the most accurate tend to be the ones

play08:53

that are implanted in the brain the

play08:55

upside is that you're reading directly

play08:56

from neural populations so the cells in

play08:59

the brain that are actually firing

play09:02

invasive bcis have the potential to

play09:05

integrate human biology with technology

play09:07

in unprecedented ways

play09:10

and scientists are slowly moving in this

play09:13

direction

play09:16

in 2018 scientist Peter Scott Morgan

play09:19

offered his own body to his profession

play09:22

he suffered from motor neurone disease

play09:24

and allowed surgeons to implant various

play09:26

chips into his body in the hope of

play09:28

extending his life whatever happens we

play09:31

will learn from it

play09:33

and we will do it better the next time

play09:35

the pioneering operations helped him

play09:37

live for another four years until his

play09:39

death in 2022.

play09:45

the brain remains one of Humanity's

play09:47

greatest enigmas

play09:49

technology that melds the brain with

play09:51

computers opens up new possibilities

play09:53

highlighting both how powerful the brain

play09:55

is and how little it is understood while

play09:59

scientists are a long way from

play10:01

understanding its Secrets there are

play10:03

grounds for both hope and concern

play10:06

it's a very scary thought when you start

play10:08

looking into into what you could do when

play10:12

you're directly interfacing the brain

play10:15

yet at the same time you you can
