So, as researchers, something that we often do is use immense resources
0
0
5000
My výskumníci často využívame nesmierne prostriedky na to,
00:24
to achieve certain capabilities, or achieve certain goals.
1
5000
3000
aby sme získali určité vlastnosti alebo dosiahli isté ciele.
00:27
And this is essential to the progress of science,
2
8000
2000
Je to nevyhnutná súčasť pokroku vedy
00:29
or exploration of what is possible.
3
10000
2000
a objavovania hraníc možného.
00:31
But it sort of creates this unfortunate situation
4
12000
2000
Ale dostávame sa tým do nešťastnej situácie,
00:34
where a tiny, tiny fraction of the world
5
15000
2000
v ktorej sa len mizivá časť sveta
00:36
can actually participate in this exploration
6
17000
2000
môže skutočne zúčastniť tohto výskumu
00:38
or can benefit from that technology.
7
19000
2000
alebo z neho mať skutočný úžitok.
00:40
And something that motivates me,
8
21000
1000
A to, čo motivuje mňa
00:41
and what gets me really excited about my research,
9
22000
2000
a pripadá mi na mojom výskume vzrušujúce
00:43
is when I see simple opportunities
10
24000
2000
sú chvíle, keď vidím jednoduché príležitosti,
00:45
to drastically change that distribution
11
26000
2000
ktoré drasticky zmenia toto rozdelenie
00:47
and make the technology accessible
12
28000
2000
a sprístupnia technológie
00:49
to a much wider percentage of the population.
13
30000
2000
oveľa väčšiemu percentu populácie.
00:51
And I'm going to show you two videos
14
32000
1000
Chystám sa vám ukázať dve videá,
00:53
that have gotten a lot of attention recently
15
34000
1000
ktoré upútali pozornosť
00:54
that I think embody this philosophy.
16
35000
2000
a podľa mňa vystihujú túto filozofiu.
00:56
And they actually use the Nintendo Wii remote.
17
37000
3000
Využívajú vlastne diaľkové ovládanie k Nintendo Wii.
00:59
Now, for those of you who aren't familiar with this device,
18
40000
2000
Takže, pre tých, ktorí toto zariadenie nepoznajú --
01:01
it's a $40 video game controller.
19
42000
3000
je to ovládač ku hernej konzole za $40.
01:04
And it's mostly advertised for its motion sensor capabilities:
20
45000
3000
Je propagovaný hlavne kvôli schopnostiam pohybového senzora,
01:07
so you can swing a tennis racket, or hit a baseball bat.
21
48000
3000
takže sa môžete zahnať tenisovou raketou alebo udierať baseballovou pálkou.
01:10
But what actually interests me a lot more
22
51000
2000
Čo ma ale zaujíma oveľa viac
01:12
is the fact that in the tip of each controller
23
53000
2000
je skutočnosť, že na konci každého ovládača
01:14
is a relatively high-performing infrared camera.
24
55000
3000
je relatívne výkonná infračervená kamera.
01:17
And I'm going to show you two demos of why this is useful.
25
58000
4000
A predvediem vám dve ukážky, prečo je to užitočné.
01:21
So here, I have my computer set up with the projector,
26
62000
4000
Takže tu mám moju počítačovú zostavu s projektorom
01:25
and I have a Wii remote sitting on top of it.
27
66000
2000
a na vrchu je položený diaľkový ovládač Wii.
01:27
And, for example, if you're in a school
28
68000
3000
A ak ste napríklad v škole,
01:30
that doesn't have a lot money, which is probably a lot of schools,
29
71000
2000
ktorá nemá veľa peňazí, čo je bežné,
01:32
or if you're in an office environment,
30
73000
2000
alebo ste v kancelárskom prostredí
01:34
and you want an interactive whiteboard,
31
75000
2000
a chcete interaktívnu tabuľu,
01:36
normally these cost about two to three thousand dollars.
32
77000
3000
normálne by ste za ňu zaplatili dve až tri tisíc dolárov.
01:39
So what I'm going to show you how to do
33
80000
2000
To, čo vám teraz predvediem, bude
01:41
is how to create one with a Wii remote.
34
82000
2000
ako si jednu vytvoriť pomocou ovládača k Wii.
01:43
Now, this requires another piece of hardware,
35
84000
3000
Je potrebný ešte jeden kus hardvéru,
01:46
which is this infrared pen.
36
87000
2000
a síce infračervené pero.
01:48
You can probably make this yourself for about five dollars
37
89000
3000
Pravdepodobne si ho dokážete vyrobiť sami za asi päť dolárov
01:51
with a quick trip to the Radio Shack.
38
92000
1000
z elektrosúčiastok.
01:52
It's essentially got a battery, a button and an infrared LED,
39
93000
3000
Je to vlastne batéria, tlačidlo a infračervená LED dióda,
01:55
and it turns on -- you guys can't see it --
40
96000
2000
ktorá sa zapne -- vy to nemôžete vidieť --
01:57
but it turns on whenever I push the button.
41
98000
2000
ale zapne sa vždy, keď stlačím tlačidlo.
01:59
Now, what this means is that if I run this piece of software,
42
100000
4000
Znamená to, že ak spustím tento malý program,
02:03
the camera sees the infrared dot,
43
104000
4000
kamera zaregistruje infračervenú bodku
02:07
and I can register the location of the camera pixels
44
108000
5000
a dokážem priradiť umiestnenie obrazových bodov kamery
02:12
to the projector pixels. And now this is like a whiteboard surface.
45
113000
3000
obrazovým bodom projektoru. A teraz je to niečo ako tabuľa.
02:15
(Applause)
46
116000
3000
(Potlesk)
02:18
So for about $50 of hardware, you can have your own whiteboard.
47
119000
3000
Takže so zariadením za asi $50 môžete mať svoju vlastnú interaktívnu tabuľu.
02:21
This is Adobe Photoshop.
48
122000
3000
Toto je Adobe Photoshop.
02:24
(Applause)
49
125000
6000
(Potlesk)
02:30
Thank you.
50
131000
1000
Ďakujem.
02:31
(Laughter)
51
132000
1000
(Smiech - "Hello"=ahoj, "Hell"=peklo)
02:32
Now, the software for this I've actually put on my website
52
133000
3000
Tento program som zavesil na svoju webovú stránku
02:35
and have let people download it for free.
53
136000
2000
a nechal ľudí stiahnuť si ho zadarmo.
02:37
And in the three months that this project has been public,
54
138000
2000
A za tri mesiace, počas ktorých bol tento projekt verejný
02:39
it's been downloaded over half a million times.
55
140000
2000
bol stiahnutý vyše pol milióna krát.
02:41
So teachers and students all around the world
56
142000
3000
Takže učitelia a študenti na celom svete
02:44
are already using this.
57
145000
1000
to už používajú.
02:45
(Applause)
58
146000
6000
(Potlesk)
02:51
I want to quickly say that although it does do it for 50 dollars,
59
152000
2000
Chcel by som ešte v rýchlosti podotknúť, že hoci to stojí 50 dolárov,
02:53
there are some limitations of this approach.
60
154000
2000
existujú isté hranice pri tomto prístupe.
02:55
But you get about 80 percent of the way there,
61
156000
2000
Ale získate asi 80 percent možností
02:57
for about one percent of the cost.
62
158000
1000
za asi jedno percento ceny.
02:58
Another nice thing is that a camera can see multiple dots,
63
159000
3000
Dobré je aj, že kamera dokáže zaznamenávať viacero bodov
03:01
so this is actually
64
162000
1000
takže je to vlastne
03:02
a multi-touch, interactive whiteboard system as well.
65
163000
2000
aj multi-dotyková interaktívna tabuľa.
03:04
(Applause)
66
165000
3000
(Potlesk)
03:07
For the second demo, I have this Wii remote
67
168000
2000
Na druhú ukážku mám tento ovládač Wii,
03:09
that's actually next to the TV.
68
170000
1000
ktorý je položený vedľa televízora.
03:11
So it's pointing away from the display,
69
172000
1000
Je namierený smerom od obrazovky,
03:12
rather than pointing at the display.
70
173000
3000
namiesto toho aby smeroval na ňu.
03:15
And why this is interesting
71
176000
2000
A je to zaujímavé preto,
03:17
is that if you put on, say, a pair of safety glasses,
72
178000
4000
lebo keď si dáte na seba priehľadné okuliare,
03:21
that have two infrared dots in them,
73
182000
2000
ktoré majú v sebe dve infračervené bodky,
03:23
what these two dots are essentially going to give you
74
184000
2000
to, čo vám tie bodky poskytnú je, že umožnia
03:25
is, give the computer an approximation of your head location.
75
186000
3000
počítaču získať približnú polohu vašej hlavy.
03:28
And why this is interesting
76
189000
1000
A to sa ukáže dôležité,
03:29
is I have this sort of application running on the computer monitor,
77
190000
3000
keď mi na počítači pobeží takýto program,
03:32
which has a 3D room, with some targets floating in it.
78
193000
3000
ktorý ukazuje 3D miestnosť s nejakými vznášajúcimi sa terčami.
03:35
And you can see that it looks like a 3D room -- if
79
196000
3000
A vidíte, že to vyzerá ako 3D miestnosť, ktorú by ste
03:38
you can see -- kind of like a video game, it sort of looks 3D,
80
199000
3000
mohli vidieť v počítačovej hre, snaží sa vyzerať 3D
03:41
but for the most part, the image looks pretty flat,
81
202000
2000
ale väčšina častí obrazu vyzerá celkom plocho
03:43
and bound to the surface of the screen.
82
204000
2000
a viazane s plochou obrazovky.
03:45
But if we turn on head tracking,
83
206000
5000
Ale ak zapneme sledovanie hlavy,
03:50
the computer can change the image that's on the screen
84
211000
2000
dokáže počítač zmeniť zobrazenie na obrazovke
03:52
and make it respond to the head movements.
85
213000
3000
a tak reagovať na pohyby hlavy.
03:55
So let's switch back to that.
86
216000
2000
Tak to zapnime.
03:57
(Laughter)
87
218000
4000
(Smiech)
04:01
(Applause)
88
222000
10000
(Potlesk)
04:11
So this has actually been a little bit startling
89
232000
3000
Toto vlastne celkom ohromilo
04:14
to the game development community.
90
235000
1000
vývojárov počítačových hier.
04:15
(Laughter)
91
236000
2000
(Smiech)
04:17
Because this is about 10 dollars of additional hardware
92
238000
3000
Pretože toto vyžaduje ďalšie zariadenie za asi 10 dolárov,
04:20
if you already have a Nintendo Wii.
93
241000
2000
ak už máte Nintendo Wii.
04:22
So I'm looking forward to seeing some games,
94
243000
2000
Takže sa celkom teším, že uvidím nejakých hráčov
04:24
and actually Louis Castle, that's him down there,
95
245000
3000
a aj Louis Castle, to je on tam dole,
04:27
last week announced that Electronic Arts,
96
248000
1000
minulý týždeň oznámil, že Electronic Arts,
04:28
one of the largest game publishers, is releasing a game in May
97
249000
4000
jeden z najväčších vydavateľov hier, v máji vydá hru,
04:32
that has a little Easter egg feature
98
253000
1000
ktoré bude mať malú skrytú súčasť
04:33
for supporting this type of head tracking.
99
254000
2000
podporujúcu tento typ sledovania polohy hlavy.
04:36
So -- and that's from less than five months
100
257000
2000
Tak -- a je to menej ako päť mesiacov
04:38
from a prototype in my lab to a major commercial product.
101
259000
3000
od prototypu v mojom laboratóriu ku komerčnému produktu.
04:41
(Applause)
102
262000
6000
(Potlesk)
04:47
Thank you.
103
268000
3000
Ďakujem.
04:50
But actually, to me, what's almost more interesting
104
271000
2000
Čo je ale pre mňa ešte zaujímavejšie
04:52
than either of these two products
105
273000
2000
ako obidva tieto produkty,
04:54
is how people actually found out about them.
106
275000
2000
je to, ako sa ľudia o nich dozvedeli.
04:56
YouTube has really changed the way, or changed the speed,
107
277000
4000
YouTube naozaj zmenil spôsob, alebo zmenil rýchlosť,
05:00
in which a single individual
108
281000
1000
akou dokáže jedinec
05:01
can actually spread an idea around the world.
109
282000
2000
rozšíriť nápad po celom svete.
05:03
You know, I'm doing some research in my lab with a video camera,
110
284000
3000
Viete, robím nejaký výskum s video kamerou v mojom laboratóriu
05:06
and within the first week, a million people had seen this work,
111
287000
3000
a počas prvého týždňa už milión ľudí túto prácu videlo
05:10
and literally within days, engineers, teachers and students
112
291000
3000
a doslova za pár dní inžinieri, učitelia a študenti
05:13
from around the world, were already posting their own YouTube videos
113
294000
4000
z celého sveta už vešali svoje vlastné videá na YouTube,
05:17
of them using my system or derivatives of this work.
114
298000
2000
na ktorých používali môj systém alebo jeho deriváty.
05:19
So I hope to see more of that in the future,
115
300000
3000
Takže dúfam že v budúcnosti toho uvidím viac
05:22
and hope online video distribution
116
303000
2000
a dúfam, že distribúcia online videa
05:24
to be embraced by the research community.
117
305000
2000
pôjde ruka v ruke s výskumom.
05:26
So thank you very much.
118
307000
1000
Tak ďakujem veľmi pekne.
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.
