Wii remote hacks | Johnny Lee

Translator: Miha Helbl Reviewer: Tilen Pigac - EFZG

Raziskovalci pogosto porabimo veliko sredstev,

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

to achieve certain capabilities, or achieve certain goals.

da bi dosegli določeno zmogljivost ali določene cilje.

To je bistvenega pomena za napredek znanosti

And this is essential to the progress of science,

in raziskovanje novih potencialov.

or exploration of what is possible.

Toda hkrati pa ustvari to nerodno situacijo,

But it creates this unfortunate situation

kjer se lahko le zelo majhen del sveta

where a tiny, tiny fraction of the world

udeleži teh raziskav

can actually participate in this exploration

ali koristi te tehnologije.

or can benefit from that technology.

Pri moji raziskavi me še posebej

Something that motivates me,

spodbudi in navduši,

and gets me really excited about my research,

ko odkrijem enostavne priložnosti,

is when I see simple opportunities

ki lahko spremenijo širjenje

to drastically change that distribution and make the technology accessible

in dostop do tehnologij

na veliko večji delež svetovnega prebivalstva.

to a much wider percentage of the population.

Pokazal vam bom dva posnetka,

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

ki sta v zadnjem času zelo popularna

in po mojem mnenju poosebljata to idejo.

that I think embody this philosophy.

Pri tem bomo uporabili Nintendov krmilnik Wii Remote.

And they actually use the Nintendo Wii Remote.

Za tiste, ki s to napravo niste seznanjeni,

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

to je igralni plošček, ki stane 40 dolarjev.

it's a $40 video game controller.

Njegova posebnost je zmožnost zaznavanja gibov.

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

Tako lahko v igri zamahnete tenis lopar ali palico za baseball.

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

Meni pa je veliko bolj zanimivo to,

But what actually interests me a lot more

da je v konici vsakega igralnega ploščka

is the fact that in the tip of each controller

vgrajena relativno visokozmogljiva infrardeča kamera.

is a relatively high-performing infrared camera.

Z dvema predstavitvama vam bom pokazal, zakaj je to uporabno.

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

Tukaj imam svoj računalnik priklopljen na projektor

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

in na projektorju leži krmilnik Wii Remote.

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

Če ste na primer v šoli

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

z nizkim proračunom, katerih je najbrž veliko,

probably a lot of schools,

ali pa ste v pisarni

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

in bi želeli imeti interaktivno tablo,

potem te ponavadi stanejo okrog 2.000 do 3.000 dolarjev.

normally these cost about two to three thousand dollars.

Zato vam bom pokazal, kako si jo lahko

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

izdelate sami s pomočjo krmilnika Wii Remote.

Poleg tega boste potrebovali tudi

Now, this requires another piece of hardware,

flomaster z infrardečo diodo v konici.

which is this infrared pen.

Za ceno 5 dolarjev ga lahko sestavite sami doma

You can probably make this yourself for about five dollars

s hitrim obiskom v bližnjo računalniško trgovino.

with a quick trip to the Radio Shack.

Sestavljen je iz baterije, gumba in infrardeče diode,

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

ki se vključi, vi tega ne vidite,

you guys can't see it --

ampak vključi se, ko pritisnete na gumb.

but it turns on whenever I push the button.

To pomeni, da lahko kamera z zagonom tega programa

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

zazna infrardečo diodo

the camera sees the infrared dot,

in uskladi položaj točk kamere

and I can register the location of the camera pixels

s točkami projektorja in postane interaktivna tabla.

to the projector pixels.

And now this is like an interactive whiteboard surface.

(Aplavz)

(Applause)

Tako lahko imate za 50 dolarjev lastno interaktivno tablo.

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

To je Adobe Photoshop.

This is Adobe Photoshop.

(Aplavz)

(Applause)

Thank you.

Hvala.

(Smeh)

(Laughter)

Ta program je naložen na moji spletni strani

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

in si ga lahko naložite brezplačno.

and have let people download it for free.

Po treh mesecih od objave projekta v javnost

In the three months this project has been public,

je bilo opravljenih več kot pol milijona prenosov.

it's been downloaded over half a million times.

Torej program že uporabljajo učitelji in učenci

So teachers and students all around the world

po celem svetu.

are already using this.

(Aplavz)

(Applause)

Rad bi samo dodal, da čeprav je zmožen vsega tega za le 50 dolarjev,

Although it does do it for 50 dollars,

je uporaba vseeno nekoliko omejena.

there are some limitations of this approach.

Toda za le en odstotek cene

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

lahko imate 80 odstotni izkoristek.

Dobro je tudi, da lahko kamera zazna več točk

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

in je s tem

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

omogočen tudi večdotični sistem.

(Aplavz)

(Applause)

Za drugo predstavitev sem krmilnik Wii Remote

For the second demo,

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

namestil poleg televizije.

Namesto, da bi ga usmeril proti zaslonu,

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

je v bistvu obrnjen stran.

To je zanimivo zato,

And why this is interesting

ker lahko s parom očal,

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

na katerih sta pritrjeni dve infrardeči diodi,

that have two infrared dots in them,

računalniku pošljete

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

približek lokacije svoje glave.

To pa je zanimivo zato,

And why this is interesting

ker imam na računalniškem zaslonu zagnano aplikacijo,

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

ki simulira tridimenzionalen prostor z lebdečimi predmeti.

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

In kot lahko vidite, je podobno 3-D prostoru,

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

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

kot v računalniški igri, nekako deluje tridimenzionalno.

Toda slika predvsem deluje ploščata

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

in pritrjena na površino zaslona.

and bound to the surface of the screen.

Toda, če vključimo sledenje glave,

But if we turn on head tracking --

lahko računalnik spremeni sliko na zaslonu

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

in jo prilagodi gibom glave.

and make it respond to the head movements.

Zato zdaj vključimo to.

So let's switch back to that.

(Smeh)

(Laughter)

(Applause)

(Aplavz)

So this has actually been a little bit startling

Razvijalci iger so se tega

v bistvu precej ustrašili.

to the game-development community.

(Smeh)

(Laughter)

Saj vse to predstavlja samo dodatnih 10 dolarjev,

Because this is about 10 dollars of additional hardware

če že imate v lasti igralno konzolo Wii.

if you already have a Nintendo Wii.

Zato se že veselim nekaterih iger.

So I'm looking forward to seeing some games,

Louis Castle, tam spodaj sedi,

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

je prejšnji teden oznanil, da bo Electronic Arts,

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

eden največjih založnikov iger, maja izdal igro,

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

v kateri bo "računalniški pirh",

ki bo podpiral tovrstno naglavno sledenje.

for supporting this type of head tracking.

To se je v manj kot petih mesecih

And that's from less than five months

iz prototipa v moji delavnici razvilo v tržni proizvod.

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

(Aplavz)

(Applause)

Thank you.

Hvala.

(Applause)

Mi je pa še bolj zanimivo,

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

kako so ljudje izvedeli

than either of these two projects

za ta dva izdelka.

is how people actually found out about them.

YouTube je močno vplival na to,

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

kako hitro lahko posameznik

in which a single individual

razširi idejo po celem svetu.

can actually spread an idea around the world.

V enem trenutku razvijam v svoji delavnici video kamero

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

in v enem tednu si je moje delo ogledalo že milijon ljudi.

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

and literally within days, engineers, teachers and students

In dobesedno v nekaj dneh so inženirji, učitelji in učenci

iz celega sveta objavljali lastne posnetke na YouTube-u,

from around the world were already posting their own YouTube videos

of them using my system or derivatives of this work.

v katerih so uporabljali moj sistem ali nekakšne predelave.

Zato upam, da bom v prihodnosti tega videl veliko več,

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

in upam, da bo raziskovalna skupnost

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

spletno distribucijo videov sprejela.

Najlepša hvala.

So thank you very much.

(Aplavz)

(Applause)
