So, as researchers, something that we often do is use immense resources
0
0
5000
Kao inovatori često koristimo razne resurse
00:24
to achieve certain capabilities, or achieve certain goals.
1
5000
3000
u ostvarenju cilja.
00:27
And this is essential to the progress of science,
2
8000
2000
To je napredak u znanosti
00:29
or exploration of what is possible.
3
10000
2000
ili izučavanje mogućeg.
00:31
But it sort of creates this unfortunate situation
4
12000
2000
No događa se da često,
00:34
where a tiny, tiny fraction of the world
5
15000
2000
tek mali dio zajednice
00:36
can actually participate in this exploration
6
17000
2000
može sudjelovati u samom istraživanju
00:38
or can benefit from that technology.
7
19000
2000
ili imati korist od dobivene tehnologije.
00:40
And something that motivates me,
8
21000
1000
Ono što me motivira,
00:41
and what gets me really excited about my research,
9
22000
2000
i što istraživanje čini uzbudljivim
00:43
is when I see simple opportunities
10
24000
2000
jest prilika otkrivanja rješenja
00:45
to drastically change that distribution
11
26000
2000
koja drastično mijenjaju odnose
00:47
and make the technology accessible
12
28000
2000
i čine tehnologiju pristupačnom
00:49
to a much wider percentage of the population.
13
30000
2000
mnogo većem postotku populacije.
00:51
And I'm going to show you two videos
14
32000
1000
Pokazat ću vam nešto
00:53
that have gotten a lot of attention recently
15
34000
1000
što trenutno privlači pažnju
00:54
that I think embody this philosophy.
16
35000
2000
i ima u sebi novi pristup.
00:56
And they actually use the Nintendo Wii remote.
17
37000
3000
Nintendo Wii daljinski upravljač (igraća konzola).
00:59
Now, for those of you who aren't familiar with this device,
18
40000
2000
Za one koji nisu upoznali ovaj uređaj,
01:01
it's a $40 video game controller.
19
42000
3000
govorim o upravljaču za video igre.
01:04
And it's mostly advertised for its motion sensor capabilities:
20
45000
3000
Poznat po svojoj mogućnosti praćenja pokreta,
01:07
so you can swing a tennis racket, or hit a baseball bat.
21
48000
3000
oponašajući pokrete u igrama.
01:10
But what actually interests me a lot more
22
51000
2000
No ono što je privuklo moju pažnju
01:12
is the fact that in the tip of each controller
23
53000
2000
je činjenica da je u svaki upravljač
01:14
is a relatively high-performing infrared camera.
24
55000
3000
ugrađena kvalitetna infracrvena kamera.
01:17
And I'm going to show you two demos of why this is useful.
25
58000
4000
Pokazat ću vam mogućnost uporabe.
01:21
So here, I have my computer set up with the projector,
26
62000
4000
Računalo je spojeno sa projektorom
01:25
and I have a Wii remote sitting on top of it.
27
66000
2000
na kojem se nalazi daljinski upravljač.
01:27
And, for example, if you're in a school
28
68000
3000
Primjerice, u školi ste
01:30
that doesn't have a lot money, which is probably a lot of schools,
29
71000
2000
koja nema dovoljno sredstava,
01:32
or if you're in an office environment,
30
73000
2000
ili radite u uredskom okruženju,
01:34
and you want an interactive whiteboard,
31
75000
2000
i potrebna vam je pametna ploča,
01:36
normally these cost about two to three thousand dollars.
32
77000
3000
čija se cijena kreće oko 10 000 kuna.
01:39
So what I'm going to show you how to do
33
80000
2000
Ono što ću vam pokazati je kako
01:41
is how to create one with a Wii remote.
34
82000
2000
iskoristiti Wii daljinski kao pametnu ploču.
01:43
Now, this requires another piece of hardware,
35
84000
3000
Potreban nam je još jedan dio,
01:46
which is this infrared pen.
36
87000
2000
a to je infracrvena olovka.
01:48
You can probably make this yourself for about five dollars
37
89000
3000
Nju je moguće izraditi za otprilike 25 kuna
01:51
with a quick trip to the Radio Shack.
38
92000
1000
kupnjom potrebnog materijala.
01:52
It's essentially got a battery, a button and an infrared LED,
39
93000
3000
Trebate bateriju, prekidač i IC LED diodu,
01:55
and it turns on -- you guys can't see it --
40
96000
2000
koja se pali
01:57
but it turns on whenever I push the button.
41
98000
2000
i pali se pritiskom prekidača.
01:59
Now, what this means is that if I run this piece of software,
42
100000
4000
Kada pokrenem aplikaciju
02:03
the camera sees the infrared dot,
43
104000
4000
kamera će uočiti infracrvenu točku,
02:07
and I can register the location of the camera pixels
44
108000
5000
i zabilježiti položaj piksela kamere i usporediti
02:12
to the projector pixels. And now this is like a whiteboard surface.
45
113000
3000
sa pikselima projektora.
02:15
(Applause)
46
116000
3000
Dobili smo površinu pametne ploče. (Pljesak)
02:18
So for about $50 of hardware, you can have your own whiteboard.
47
119000
3000
Za 300 kuna dobili ste pametnu ploču.
02:21
This is Adobe Photoshop.
48
122000
3000
Ovo je Adobe Photoshop.
02:24
(Applause)
49
125000
6000
(Pljesak)
02:30
Thank you.
50
131000
1000
Hvala vam.
02:31
(Laughter)
51
132000
1000
(Smijeh)
02:32
Now, the software for this I've actually put on my website
52
133000
3000
Aplikacija za ovo na mojoj je internet stranici
02:35
and have let people download it for free.
53
136000
2000
i možete je preuzeti besplatno.
02:37
And in the three months that this project has been public,
54
138000
2000
U tri mjeseca koliko je ovaj projekt dostupan
02:39
it's been downloaded over half a million times.
55
140000
2000
zabilježeno je preko 500 000 preuzimanja.
02:41
So teachers and students all around the world
56
142000
3000
Učitelji i učenici diljem svijeta
02:44
are already using this.
57
145000
1000
već je koriste.
02:45
(Applause)
58
146000
6000
(Pljesak)
02:51
I want to quickly say that although it does do it for 50 dollars,
59
152000
2000
Iako funkcionira za nekih 300 kuna,
02:53
there are some limitations of this approach.
60
154000
2000
ovaj pristup ima svojih ograničenja.
02:55
But you get about 80 percent of the way there,
61
156000
2000
No iskoristivost od 80% usporedite
02:57
for about one percent of the cost.
62
158000
1000
sa oko 1% stvarne cijene pametne ploče.
02:58
Another nice thing is that a camera can see multiple dots,
63
159000
3000
Kamera bilježi više točaka,
03:01
so this is actually
64
162000
1000
i moguća je uporaba više korisnika
03:02
a multi-touch, interactive whiteboard system as well.
65
163000
2000
pametne ploče istovremeno.
03:04
(Applause)
66
165000
3000
(Pljesak)
03:07
For the second demo, I have this Wii remote
67
168000
2000
Sljedeća demonstracija uključuje Wii daljinski
03:09
that's actually next to the TV.
68
170000
1000
koji se nalazi uz televizor.
03:11
So it's pointing away from the display,
69
172000
1000
Usmjeren je suprotno od ekrana,
03:12
rather than pointing at the display.
70
173000
3000
umjesto prema njemu.
03:15
And why this is interesting
71
176000
2000
Ovo je zanimljivo stoga što
03:17
is that if you put on, say, a pair of safety glasses,
72
178000
4000
stavimo li npr. okvir naočala,
03:21
that have two infrared dots in them,
73
182000
2000
sa dvije infracrvene točke na njemu,
03:23
what these two dots are essentially going to give you
74
184000
2000
ono što ćemo dobiti je
03:25
is, give the computer an approximation of your head location.
75
186000
3000
da računalo procijeni položaj naše glave.
03:28
And why this is interesting
76
189000
1000
Ono što je zanimljivo
03:29
is I have this sort of application running on the computer monitor,
77
190000
3000
je aplikacija vidljiva na ekranu monitora,
03:32
which has a 3D room, with some targets floating in it.
78
193000
3000
i prikazuje 3D sobu
03:35
And you can see that it looks like a 3D room -- if
79
196000
3000
sa plutajućim objektima.
03:38
you can see -- kind of like a video game, it sort of looks 3D,
80
199000
3000
Poput video igre,
03:41
but for the most part, the image looks pretty flat,
81
202000
2000
no daje dojam plošnosti,
03:43
and bound to the surface of the screen.
82
204000
2000
priljubljena uz površinu ekrana.
03:45
But if we turn on head tracking,
83
206000
5000
Uključimo li praćenje pokreta glave,
03:50
the computer can change the image that's on the screen
84
211000
2000
promijenit će se slika na ekranu
03:52
and make it respond to the head movements.
85
213000
3000
pri pomaku glave.
03:55
So let's switch back to that.
86
216000
2000
Vratimo se na trenutak.
03:57
(Laughter)
87
218000
4000
(Smijeh)
04:01
(Applause)
88
222000
10000
(Pljesak)
04:11
So this has actually been a little bit startling
89
232000
3000
Ovo je vjerojatno uzbudljivo
04:14
to the game development community.
90
235000
1000
proizvođačima igara.
04:15
(Laughter)
91
236000
2000
(Smijeh)
04:17
Because this is about 10 dollars of additional hardware
92
238000
3000
Jer su troškovi neznatno veći
04:20
if you already have a Nintendo Wii.
93
241000
2000
ako već imate Nintendo Wii.
04:22
So I'm looking forward to seeing some games,
94
243000
2000
Stoga očekujem igre,
04:24
and actually Louis Castle, that's him down there,
95
245000
3000
a budući da je Louis Castle ovdje,
04:27
last week announced that Electronic Arts,
96
248000
1000
i najavio je da Electronic Arts,
04:28
one of the largest game publishers, is releasing a game in May
97
249000
4000
u svibnju objavljuje
04:32
that has a little Easter egg feature
98
253000
1000
igru koja kao posebno iznenađenje
04:33
for supporting this type of head tracking.
99
254000
2000
podržava sustav praćenja pokreta glave.
04:36
So -- and that's from less than five months
100
257000
2000
Dakle, u vremenskom periodu od 5 mjeseci
04:38
from a prototype in my lab to a major commercial product.
101
259000
3000
od prototipa u laboratoriju do gotovog proizvoda.
04:41
(Applause)
102
262000
6000
(Pljesak)
04:47
Thank you.
103
268000
3000
Hvala vam.
04:50
But actually, to me, what's almost more interesting
104
271000
2000
Ono što je zanimljivije
04:52
than either of these two products
105
273000
2000
od oba ova proizvoda
04:54
is how people actually found out about them.
106
275000
2000
je način na koji su ljudi saznali za njih.
04:56
YouTube has really changed the way, or changed the speed,
107
277000
4000
YouTube je utjecao na način i brzinu,
05:00
in which a single individual
108
281000
1000
kojom pojedinac
05:01
can actually spread an idea around the world.
109
282000
2000
širi svoju ideju svijetom.
05:03
You know, I'm doing some research in my lab with a video camera,
110
284000
3000
Sve što radim, snimam
05:06
and within the first week, a million people had seen this work,
111
287000
3000
i u prvom tjednu, mnogi su vidjeli moj rad,
05:10
and literally within days, engineers, teachers and students
112
291000
3000
i u nekoliko dana, inženjeri, učitelji i učenici
05:13
from around the world, were already posting their own YouTube videos
113
294000
4000
iz cijelog svijeta, objavljuju svoje radove
05:17
of them using my system or derivatives of this work.
114
298000
2000
koristeći moj sustav ili modifikaciju istog.
05:19
So I hope to see more of that in the future,
115
300000
3000
Stoga očekujem više takvih pokušaja,
05:22
and hope online video distribution
116
303000
2000
s nadom da će mrežnu video distribuciju
05:24
to be embraced by the research community.
117
305000
2000
prihvatiti i istraživačka zajednica.
05:26
So thank you very much.
118
307000
1000
Zahvaljujem na pažnji.
05:27
(Applause)

ABOUT THE SPEAKER
Johnny Lee - Human-computer interaction researcherResearcher 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.
