Could AI Give You X-Ray Vision? | Tara Boroushaki | TED

As a teenager,

I was fascinated with the wizarding world.

I wanted to be like Hermione Granger.

I wanted to be a powerful witch with a wand.

Out of all the spells, I really liked "Accio."

I could say "Accio" and name anything and it would fly into my hands,

even if it's a restricted book,

locked and hidden inside the headmaster's office.

But as you might have noticed, I did not get into Hogwarts.

So I came to my backup school, MIT.

(Laughter)

And I made my own magic.

I can now --

I can have the spells now

that are even more powerful than Hermione's,

because I don't need a wand.

I can see the invisible.

Let me show you my first spell.

For example, I want to find my black shirt in my closet that I lost.

I put on my AR headset and I say "Accio."

Within a matter of seconds, my shirt will light up.

Like I said, I can see the invisible.

(Applause)

So how does this spell work?

How did I make an AR headset

able to see what my own eyes cannot see?

My trick is to use wireless signals like Bluetooth and Wi-Fi.

These signals are great.

This is exactly why you can get Wi-Fi from another room.

So these signals are sent by this headset.

They are scattered in the environment.

They go through boxes

and then are reflected back

from all of these hidden objects, including my shirt.

We then design algorithms

that use these reflected signals to find these objects.

Let me show you how these algorithms work.

First, the headset tries to understand its environment

by creating a virtual 3D map.

And then as I walk in the environment,

it keeps sending these wireless signals,

tries to collect all of the reflections,

and then combines them to collect this information,

and then tries to locate the object that I was looking for.

Then after some time,

it becomes confident about it and then tells me,

"Here it is."

This is the glow,

which is where the object I want is,

and I can go and grab it.

Besides helping me having these magical powers,

it has a lot of industrial applications.

For example, in a warehouse,

it can help warehouse workers to find packages,

and then it can guide them through the warehouse to find these packages.

In a retail store,

it can help the store associates to pack customer's orders

and find misplaced items.

It also has a lot of other applications in logistics and manufacturing.

So having X-ray vision is very cool.

It's better than what Hermione had.

But sometimes I'm just so lazy,

I don't want to go ahead and put my headset on

and then say "Accio" and then go and find my key,

grab it under the pile.

So I was thinking, what if I had a robot that knew my spell?

So I taught my spells to a robot.

My robot can find my keys and bring them to me.

Let me show it to you.

For example, here,

my keychain is hidden under the pile in the basket.

My robot is able to search the environment

and locate my keys with centimeter-level accuracy,

purposefully declutter the environment and then grab the keys

and bring them to me.

So how do we do this?

We built a specialized gripper instead of a wand.

So it has a camera and a wireless sensor,

which sends similar signals like the headset that I just talked about.

So this is great, now this gripper can locate the keys.

But there's one challenge.

What if I put my robot in a completely new environment?

For example, put it in the living room and ask it to find a remote control.

How does this robot adapt itself to a completely new environment

and a completely new object?

If the robot does exactly the same steps as before,

then it can only find a key in a basket.

We designed an AI algorithm

specifically to help this robot to adapt itself to a completely new environment

and find objects it has never seen before.

For example, here it's trying to find a remote control on a couch

in a living room it has never seen before.

It's able to find it and then bring it to me,

and I can go and grab this remote control and then watch my favorite show.

Magical X-ray vision can change the way we think about our environment

and the way we interact with our environment.

It opens up new possibilities that we never thought are possible.

For example, it can help our future robots in our homes to help us.

It can also help us interact with our future smart homes

in ways we never imagined before.

But the application that I'm personally very excited about

is helping our first responders

to find and track humans in conditions with low visibility.

Or helping humans under the rubble after disaster hits.

And as the cherry on top,

it can help those of us who did not get into Hogwarts

to get one step closer to the wizarding world.

Thank you.
