Why you should listen

To understand Johnny Lee, just take a look at his website. Aside from his Wii Remote hacks -- voted the #1 tech demo of all time by Digg -- you can see all the other places his mind has turned: typography, photography, urban renewal ... to say nothing of his interesting sideline in Little Great Ideas, like the hypnotic "___ will ___ you."

After earning his PhD from the Human-Computer Interaction Institute at Carnegie Mellon University, he joined the team at Microsoft responsible for Project Natal, a controller-free motion sensing device for the Xbox 360. He's since turned his attention to accelerated technology R&D at Google.

Now, for those of you who aren'tnisu familiarupoznat with this deviceuređaj,
18
40000
2000
Za one koji nisu upoznali ovaj uređaj,
01:01
it's a $40 videovideo gameigra controllerkontrolor.
19
42000
3000
govorim o upravljaču za video igre.
01:04
And it's mostlyuglavnom advertisedreklamirao for its motionpokret sensorsenzor capabilitiessposobnosti:

01:10
But what actuallyzapravo interestsinteresi me a lot more
22
51000
2000
No ono što je privuklo moju pažnju
01:12
is the factčinjenica that in the tipSavjet of eachsvaki controllerkontrolor
23
53000
2000
je činjenica da je u svaki upravljač
01:14
is a relativelyrelativno high-performingizvedbom infraredinfracrveni camerafotoaparat.
24
55000
3000
ugrađena kvalitetna infracrvena kamera.
01:17
And I'm going to showpokazati you two demosdemos of why this is usefulkoristan.
25
58000
4000
Pokazat ću vam mogućnost uporabe.
01:21
So here, I have my computerračunalo setset up with the projectorprojektor,
26
62000
4000
Računalo je spojeno sa projektorom
01:25
and I have a WiiWii remotedaljinski sittingsjedenje on topvrh of it.
27
66000
2000
na kojem se nalazi daljinski upravljač.
01:27
And, for exampleprimjer, if you're in a schoolškola
28
68000
3000
Primjerice, u školi ste
01:30
that doesn't have a lot moneynovac, whichkoji is probablyvjerojatno a lot of schoolsškola,
29
71000
2000
koja nema dovoljno sredstava,
01:32
or if you're in an officeured environmentokolina,
30
73000
2000
ili radite u uredskom okruženju,
01:34
and you want an interactiveinteraktivni whiteboardploča,
31
75000
2000
i potrebna vam je pametna ploča,
01:36
normallynormalno these costcijena about two to threetri thousandtisuću dollarsdolara.
32
77000
3000
čija se cijena kreće oko 10 000 kuna.
01:39
So what I'm going to showpokazati you how to do
33
80000
2000
Ono što ću vam pokazati je kako
01:41
is how to createstvoriti one with a WiiWii remotedaljinski.
34
82000
2000
iskoristiti Wii daljinski kao pametnu ploču.
01:43
Now, this requirestraži anotherjoš piecekomad of hardwarehardver,
35
84000
3000
Potreban nam je još jedan dio,
01:46
whichkoji is this infraredinfracrveni penpero.
36
87000
2000
a to je infracrvena olovka.
01:48
You can probablyvjerojatno make this yourselfsami for about fivepet dollarsdolara
37
89000
3000
Nju je moguće izraditi za otprilike 25 kuna
01:51
with a quickbrz tripputovanje to the RadioRadio ShackKoliba.
38
92000
1000
kupnjom potrebnog materijala.
01:52
It's essentiallyu srži got a batterybaterija, a buttondugme and an infraredinfracrveni LED,
39
93000
3000
Trebate bateriju, prekidač i IC LED diodu,
01:55
and it turnsokreti on -- you guys can't see it --
40
96000
2000
koja se pali
01:57
but it turnsokreti on wheneverkada I pushgurnuti the buttondugme.
41

2000
i pali se pritiskom prekidača.
01:59
Now, what this meanssredstva is that if I runtrčanje this piecekomad of softwaresoftver,
42
100000
4000
Kada pokrenem aplikaciju
02:03
the camerafotoaparat seesvidi the infraredinfracrveni dottočka,
43
104000
4000
kamera će uočiti infracrvenu točku,
02:07
and I can registerRegistrirajte se the locationmjesto of the camerafotoaparat pixelspiksela
44
108000
5000
i zabilježiti položaj piksela kamere i usporediti
02:12
to the projectorprojektor pixelspiksela. And now this is like a whiteboardploča surfacepovršinski.

02:15
(ApplausePljesak)
46
116000
3000
Dobili smo površinu pametne ploče. (Pljesak)
02:18
So for about $50 of hardwarehardver, you can have your ownvlastiti whiteboardploča.
47

3000
Za 300 kuna dobili ste pametnu ploču.
02:21
This is AdobeNepečena opeka PhotoshopPhotoshop.

Ovo je Adobe Photoshop.
02:24

02:30
Thank you.

Hvala vam.
02:31
(LaughterSmijeh)
51
132000
1000
(Smijeh)
02:32
Now, the softwaresoftver for this I've actuallyzapravo put on my websiteweb stranica
52
133000
3000
Aplikacija za ovo na mojoj je internet stranici
02:35
and have let people downloadpreuzimanje datoteka it for freebesplatno.
53
136000
2000
i možete je preuzeti besplatno.
02:37
And in the threetri monthsmjeseci that this projectprojekt has been publicjavnost,
54
138000
2000
U tri mjeseca koliko je ovaj projekt dostupan
02:39
it's been downloadedpreuzeto over halfpola a millionmilijuna timesputa.
55
140000
2000
zabilježeno je preko 500 000 preuzimanja.
02:41
So teachersučitelji and studentsstudenti all around the worldsvijet
56
142000
3000
Učitelji i učenici diljem svijeta
02:44
are alreadyveć usingkoristeći this.
57
145000
1000
već je koriste.
02:45
(ApplausePljesak)
58
146000
6000
(Pljesak)
02:51
I want to quicklybrzo say that althoughiako it does do it for 50 dollarsdolara,
59
152000
2000
Iako funkcionira za nekih 300 kuna,
02:53
there are some limitationsograničenja of this approachpristup.
60
154000
2000
ovaj pristup ima svojih ograničenja.
02:55
But you get about 80 percentposto of the way there,
61
156000
2000
No iskoristivost od 80% usporedite
02:57
for about one percentposto of the costcijena.
62
158000
1000
sa oko 1% stvarne cijene pametne ploče.
02:58
AnotherJoš jedan nicelijepo thing is that a camerafotoaparat can see multiplevišekratnik dotstočkice,
63
159000
3000
Kamera bilježi više točaka,
03:01
so this is actuallyzapravo
64
162000
1000
i moguća je uporaba više korisnika
03:02
a multi-touchmulti-touch, interactiveinteraktivni whiteboardploča systemsistem as well.
65
163000
2000
pametne ploče istovremeno.
03:04
(ApplausePljesak)
66
165000
3000
(Pljesak)
03:07
For the seconddrugi demoogledni primjerak, I have this WiiWii remotedaljinski
67
168000
2000
Sljedeća demonstracija uključuje Wii daljinski
03:09
that's actuallyzapravo nextSljedeći to the TVTV.
68
170000
1000
koji se nalazi uz televizor.
03:11
So it's pointingpokazuje away from the displayprikaz,
69
172000
1000
Usmjeren je suprotno od ekrana,
03:12
ratherradije than pointingpokazuje at the displayprikaz.
70
173000
3000
umjesto prema njemu.
03:15
And why this is interestingzanimljiv
71
176000
2000
Ovo je zanimljivo stoga što
03:17
is that if you put on, say, a pairpar of safetysigurnosni glassesnaočale,
72
178000
4000
stavimo li npr. okvir naočala,
03:21
that have two infraredinfracrveni dotstočkice in them,
73
182000
2000
sa dvije infracrvene točke na njemu,
03:23
what these two dotstočkice are essentiallyu srži going to give you
74
184000
2000
ono što ćemo dobiti je
03:25
is, give the computerračunalo an approximationaproksimacija of your headglava locationmjesto.
75
186000
3000
da računalo procijeni položaj naše glave.
03:28
And why this is interestingzanimljiv
76
189000
1000
Ono što je zanimljivo
03:29
is I have this sortvrsta of applicationprimjena runningtrčanje on the computerračunalo monitormonitor,
77
190000
3000
je aplikacija vidljiva na ekranu monitora,
03:32
whichkoji has a 3D roomsoba, with some targetsciljevi floatingplivajući in it.
78
193000
3000
i prikazuje 3D sobu
03:35
And you can see that it looksizgled like a 3D roomsoba -- if
79
196000

03:38
you can see -- kindljubazan of like a videovideo gameigra, it sortvrsta of looksizgled 3D,
80
199000
3000
Poput video igre,
03:41
but for the mostnajviše partdio, the imageslika looksizgled prettyprilično flatravan,
81
202000
2000
no daje dojam plošnosti,
03:43
and boundgranica to the surfacepovršinski of the screenzaslon.
82
204000
2000
priljubljena uz površinu ekrana.
03:45
But if we turnskretanje on headglava trackingpraćenje,
83
206000
5000
Uključimo li praćenje pokreta glave,
03:50
the computerračunalo can changepromijeniti the imageslika that's on the screenzaslon
84
211000
2000
promijenit će se slika na ekranu
03:52
and make it respondodgovarati to the headglava movementspokreti.
85

03:55

ABOUT THE SPEAKER
Johnny Lee - Human-computer interaction researcher
Researcher Johnny Lee became a YouTube star with his demo of Wii Remote hacks -- bending the low-cost game piece to power an interactive whiteboard, a multitouch surface, a head-mounted display ...

Why you should listen

To understand Johnny Lee, just take a look at his website. Aside from his Wii Remote hacks -- voted the #1 tech demo of all time by Digg -- you can see all the other places his mind has turned: typography, photography, urban renewal ... to say nothing of his interesting sideline in Little Great Ideas, like the hypnotic "___ will ___ you."

After earning his PhD from the Human-Computer Interaction Institute at Carnegie Mellon University, he joined the team at Microsoft responsible for Project Natal, a controller-free motion sensing device for the Xbox 360. He's since turned his attention to accelerated technology R&D at Google.
