Kao inovatori često koristimo razne resurse

So, as researchers, something that we often do is use immense resources

to achieve certain capabilities, or achieve certain goals.

u ostvarenju cilja.

To je napredak u znanosti

And this is essential to the progress of science,

ili izučavanje mogućeg.

or exploration of what is possible.

No događa se da često,

But it creates this unfortunate situation

tek mali dio zajednice

where a tiny, tiny fraction of the world

može sudjelovati u samom istraživanju

can actually participate in this exploration

ili imati korist od dobivene tehnologije.

or can benefit from that technology.

Ono što me motivira,

Something that motivates me,

i što istraživanje čini uzbudljivim

and gets me really excited about my research,

jest prilika otkrivanja rješenja

is when I see simple opportunities

koja drastično mijenjaju odnose

to drastically change that distribution and make the technology accessible

i čine tehnologiju pristupačnom

mnogo većem postotku populacije.

to a much wider percentage of the population.

Pokazat ću vam nešto

I'm going to show you two videos that have gotten a lot of attention

što trenutno privlači pažnju

i ima u sebi novi pristup.

that I think embody this philosophy.

Nintendo Wii daljinski upravljač (igraća konzola).

And they actually use the Nintendo Wii Remote.

Za one koji nisu upoznali ovaj uređaj,

For those of you who aren't familiar with this device,

govorim o upravljaču za video igre.

it's a $40 video game controller.

Poznat po svojoj mogućnosti praćenja pokreta,

And it's mostly advertised for its motion-sensing capabilities:

oponašajući pokrete u igrama.

so you can swing a tennis racket, or hit a baseball bat.

No ono što je privuklo moju pažnju

But what actually interests me a lot more

je činjenica da je u svaki upravljač

is the fact that in the tip of each controller

ugrađena kvalitetna infracrvena kamera.

is a relatively high-performing infrared camera.

Pokazat ću vam mogućnost uporabe.

And I'm going to show you two demos of why this is useful.

Računalo je spojeno sa projektorom

So here, I have my computer set up with the projector,

na kojem se nalazi daljinski upravljač.

and I have a Wii Remote sitting on top of it.

Primjerice, u školi ste

And, for example, if you're in a school that doesn't have a lot money,

koja nema dovoljno sredstava,

probably a lot of schools,

ili radite u uredskom okruženju,

or if you're in an office environment, and you want an interactive whiteboard,

i potrebna vam je pametna ploča,

čija se cijena kreće oko 10 000 kuna.

normally these cost about two to three thousand dollars.

Ono što ću vam pokazati je kako

So I'm going to show you how to create one with a Wii Remote.

iskoristiti Wii daljinski kao pametnu ploču.

Potreban nam je još jedan dio,

Now, this requires another piece of hardware,

a to je infracrvena olovka.

which is this infrared pen.

Nju je moguće izraditi za otprilike 25 kuna

You can probably make this yourself for about five dollars

kupnjom potrebnog materijala.

with a quick trip to the Radio Shack.

Trebate bateriju, prekidač i IC LED diodu,

It's got a battery, a button and an infrared LED --

koja se pali

you guys can't see it --

i pali se pritiskom prekidača.

but it turns on whenever I push the button.

Kada pokrenem aplikaciju

Now, what this means is that if I run this piece of software,

kamera će uočiti infracrvenu točku,

the camera sees the infrared dot,

i zabilježiti položaj piksela kamere i usporediti

and I can register the location of the camera pixels

sa pikselima projektora.

to the projector pixels.

And now this is like an interactive whiteboard surface.

Dobili smo površinu pametne ploče. (Pljesak)

(Applause)

Za 300 kuna dobili ste pametnu ploču.

So for about $50 of hardware, you can have your own whiteboard.

Ovo je Adobe Photoshop.

This is Adobe Photoshop.

(Pljesak)

(Applause)

Thank you.

Hvala vam.

(Smijeh)

(Laughter)

Aplikacija za ovo na mojoj je internet stranici

The software for this I've actually put on my website

i možete je preuzeti besplatno.

and have let people download it for free.

U tri mjeseca koliko je ovaj projekt dostupan

In the three months this project has been public,

zabilježeno je preko 500 000 preuzimanja.

it's been downloaded over half a million times.

Učitelji i učenici diljem svijeta

So teachers and students all around the world

već je koriste.

are already using this.

(Pljesak)

(Applause)

Iako funkcionira za nekih 300 kuna,

Although it does do it for 50 dollars,

ovaj pristup ima svojih ograničenja.

there are some limitations of this approach.

No iskoristivost od 80% usporedite

You get about 80 percent of the way there, for one percent of the cost.

sa oko 1% stvarne cijene pametne ploče.

Kamera bilježi više točaka,

Another nice thing is that a camera can see multiple dots,

i moguća je uporaba više korisnika

so this is actually a multi-touch, interactive whiteboard system as well.

pametne ploče istovremeno.

(Pljesak)

(Applause)

Sljedeća demonstracija uključuje Wii daljinski

For the second demo,

I have this Wii Remote that's actually next to the TV.

koji se nalazi uz televizor.

Usmjeren je suprotno od ekrana,

So it's pointing away from the display, rather than pointing at the display.

umjesto prema njemu.

Ovo je zanimljivo stoga što

And why this is interesting

stavimo li npr. okvir naočala,

is that if you put on, say, a pair of safety glasses,

sa dvije infracrvene točke na njemu,

that have two infrared dots in them,

ono što ćemo dobiti je

they are going to give the computer an approximation of your head location.

da računalo procijeni položaj naše glave.

Ono što je zanimljivo

And why this is interesting

je aplikacija vidljiva na ekranu monitora,

is I have this sort of application running on the computer monitor,

i prikazuje 3D sobu

which has a 3D room, with some targets floating in it.

sa plutajućim objektima.

And you can see that it looks like a 3D room.

kind of like a video game, it sort of looks 3D,

Poput video igre,

no daje dojam plošnosti,

but for the most part, the image looks pretty flat,

priljubljena uz površinu ekrana.

and bound to the surface of the screen.

Uključimo li praćenje pokreta glave,

But if we turn on head tracking --

promijenit će se slika na ekranu

the computer can change the image that's on the screen

pri pomaku glave.

and make it respond to the head movements.

Vratimo se na trenutak.

So let's switch back to that.

(Smijeh)

(Laughter)

(Applause)

(Pljesak)

So this has actually been a little bit startling

Ovo je vjerojatno uzbudljivo

proizvođačima igara.

to the game-development community.

(Smijeh)

(Laughter)

Jer su troškovi neznatno veći

Because this is about 10 dollars of additional hardware

ako već imate Nintendo Wii.

if you already have a Nintendo Wii.

Stoga očekujem igre,

So I'm looking forward to seeing some games,

a budući da je Louis Castle ovdje,

and actually Louis Castle, that's him down there,

i najavio je da Electronic Arts,

last week announced that Electronic Arts, one of the largest game publishers,

u svibnju objavljuje

is releasing a game in May that has a little Easter egg feature

igru koja kao posebno iznenađenje

podržava sustav praćenja pokreta glave.

for supporting this type of head tracking.

Dakle, u vremenskom periodu od 5 mjeseci

And that's from less than five months

od prototipa u laboratoriju do gotovog proizvoda.

from a prototype in my lab to a major commercial product.

(Pljesak)

(Applause)

Thank you.

Hvala vam.

(Applause)

Ono što je zanimljivije

But actually, to me, what's almost more interesting

od oba ova proizvoda

than either of these two projects

je način na koji su ljudi saznali za njih.

is how people actually found out about them.

YouTube je utjecao na način i brzinu,

YouTube has really changed the way, or changed the speed,

kojom pojedinac

in which a single individual

širi svoju ideju svijetom.

can actually spread an idea around the world.

Sve što radim, snimam

I'm doing some research in my lab with a video camera,

i u prvom tjednu, mnogi su vidjeli moj rad,

and within the first week, a million people had seen this work,

and literally within days, engineers, teachers and students

i u nekoliko dana, inženjeri, učitelji i učenici

iz cijelog svijeta, objavljuju svoje radove

from around the world were already posting their own YouTube videos

of them using my system or derivatives of this work.

koristeći moj sustav ili modifikaciju istog.

Stoga očekujem više takvih pokušaja,

So I hope to see more of that in the future,

s nadom da će mrežnu video distribuciju

and hope online video distribution to be embraced by the research community.

prihvatiti i istraživačka zajednica.

Zahvaljujem na pažnji.

So thank you very much.

(Pljesak)

(Applause)
