Johnny Lee predstavi programsko opremo, ki jo je skupaj s krmilnikom Wii Remote in nekaj poceni sestavnimi deli združil v napredna izobrazbena orodja. Tako je igralni plošček, vreden 40 dolarjev, spremenil v interaktivno tablo, na dotik občutljivi zaslon (touchscreen) in naglavni senzor za premikanje pogleda v tridimenzionalnem okolju na zaslonu (3-D viewer).

So, as researchers, something that we often do is use immense resources
0
0
5000
Raziskovalci pogosto porabimo veliko sredstev,
00:24
to achieve certain capabilities, or achieve certain goals.
1
5000
3000
da bi dosegli določeno zmogljivost ali določene cilje.
00:27
And this is essential to the progress of science,
2
8000
2000
To je bistvenega pomena za napredek znanosti
00:29
or exploration of what is possible.
3
10000
2000
in raziskovanje novih potencialov.
00:31
But it sort of creates this unfortunate situation
4
12000
2000
Toda hkrati pa ustvari to nerodno situacijo,
00:34
where a tiny, tiny fraction of the world
5
15000
2000
kjer se lahko le zelo majhen del sveta
00:36
can actually participate in this exploration
6
17000
2000
udeleži teh raziskav
00:38
or can benefit from that technology.
7
19000
2000
ali koristi te tehnologije.
00:40
And something that motivates me,
8
21000
1000
Pri moji raziskavi me še posebej
00:41
and what gets me really excited about my research,
9
22000
2000
spodbudi in navduši,
00:43
is when I see simple opportunities
10
24000
2000
ko odkrijem enostavne priložnosti,
00:45
to drastically change that distribution
11
26000
2000
ki lahko spremenijo širjenje
00:47
and make the technology accessible
12
28000
2000
in dostop do tehnologij
00:49
to a much wider percentage of the population.
13
30000
2000
na veliko večji delež svetovnega prebivalstva.
00:51
And I'm going to show you two videos
14
32000
1000
Pokazal vam bom dva posnetka,
00:53
that have gotten a lot of attention recently
15
34000
1000
ki sta v zadnjem času zelo popularna
00:54
that I think embody this philosophy.
16
35000
2000
in po mojem mnenju poosebljata to idejo.
00:56
And they actually use the Nintendo Wii remote.
17
37000
3000
Pri tem bomo uporabili Nintendov krmilnik Wii Remote.
00:59
Now, for those of you who aren't familiar with this device,
18
40000
2000
Za tiste, ki s to napravo niste seznanjeni,
01:01
it's a $40 video game controller.
19
42000
3000
to je igralni plošček, ki stane 40 dolarjev.
01:04
And it's mostly advertised for its motion sensor capabilities:
20
45000
3000
Njegova posebnost je zmožnost zaznavanja gibov.
01:07
so you can swing a tennis racket, or hit a baseball bat.
21
48000
3000
Tako lahko v igri zamahnete tenis lopar ali palico za baseball.
01:10
But what actually interests me a lot more
22
51000
2000
Meni pa je veliko bolj zanimivo to,
01:12
is the fact that in the tip of each controller
23
53000
2000
da je v konici vsakega igralnega ploščka
01:14
is a relatively high-performing infrared camera.
24
55000
3000
vgrajena relativno visokozmogljiva infrardeča kamera.
01:17
And I'm going to show you two demos of why this is useful.
25
58000
4000
Z dvema predstavitvama vam bom pokazal, zakaj je to uporabno.
01:21
So here, I have my computer set up with the projector,
26
62000
4000
Tukaj imam svoj računalnik priklopljen na projektor
01:25
and I have a Wii remote sitting on top of it.
27
66000
2000
in na projektorju leži krmilnik Wii Remote.
01:27
And, for example, if you're in a school
28
68000
3000
Če ste na primer v šoli
01:30
that doesn't have a lot money, which is probably a lot of schools,
29
71000
2000
z nizkim proračunom, katerih je najbrž veliko,
01:32
or if you're in an office environment,
30
73000
2000
ali pa ste v pisarni
01:34
and you want an interactive whiteboard,
31
75000
2000
in bi želeli imeti interaktivno tablo,
01:36
normally these cost about two to three thousand dollars.
32
77000
3000
potem te ponavadi stanejo okrog 2.000 do 3.000 dolarjev.
01:39
So what I'm going to show you how to do
33
80000
2000
Zato vam bom pokazal, kako si jo lahko
01:41
is how to create one with a Wii remote.
34
82000
2000
izdelate sami s pomočjo krmilnika Wii Remote.
01:43
Now, this requires another piece of hardware,
35
84000
3000
Poleg tega boste potrebovali tudi
01:46
which is this infrared pen.
36
87000
2000
flomaster z infrardečo diodo v konici.
01:48
You can probably make this yourself for about five dollars
37
89000
3000
Za ceno 5 dolarjev ga lahko sestavite sami doma
01:51
with a quick trip to the Radio Shack.
38
92000
1000
s hitrim obiskom v bližnjo računalniško trgovino.
01:52
It's essentially got a battery, a button and an infrared LED,
39
93000
3000
Sestavljen je iz baterije, gumba in infrardeče diode,
01:55
and it turns on -- you guys can't see it --
40
96000
2000
ki se vključi, vi tega ne vidite,
01:57
but it turns on whenever I push the button.
41
98000
2000
ampak vključi se, ko pritisnete na gumb.
01:59
Now, what this means is that if I run this piece of software,
42
100000
4000
To pomeni, da lahko kamera z zagonom tega programa
02:03
the camera sees the infrared dot,
43
104000
4000
zazna infrardečo diodo
02:07
and I can register the location of the camera pixels
44
108000
5000
in uskladi položaj točk kamere
02:12
to the projector pixels. And now this is like a whiteboard surface.
45
113000
3000
s točkami projektorja in postane interaktivna tabla.
02:15
(Applause)
46
116000
3000
(Aplavz)
02:18
So for about $50 of hardware, you can have your own whiteboard.
47
119000
3000
Tako lahko imate za 50 dolarjev lastno interaktivno tablo.
02:21
This is Adobe Photoshop.
48
122000
3000
To je Adobe Photoshop.
02:24
(Applause)
49
125000
6000
(Aplavz)
02:30
Thank you.
50
131000
1000
Hvala.
02:31
(Laughter)
51
132000
1000
(Smeh)
02:32
Now, the software for this I've actually put on my website
52
133000
3000
Ta program je naložen na moji spletni strani
02:35
and have let people download it for free.
53
136000
2000
in si ga lahko naložite brezplačno.
02:37
And in the three months that this project has been public,
54
138000
2000
Po treh mesecih od objave projekta v javnost
02:39
it's been downloaded over half a million times.
55
140000
2000
je bilo opravljenih več kot pol milijona prenosov.
02:41
So teachers and students all around the world
56
142000
3000
Torej program že uporabljajo učitelji in učenci
02:44
are already using this.
57
145000
1000
po celem svetu.
02:45
(Applause)
58
146000
6000
(Aplavz)
02:51
I want to quickly say that although it does do it for 50 dollars,
59
152000
2000
Rad bi samo dodal, da čeprav je zmožen vsega tega za le 50 dolarjev,
02:53
there are some limitations of this approach.
60
154000
2000
je uporaba vseeno nekoliko omejena.
02:55
But you get about 80 percent of the way there,
61
156000
2000
Toda za le en odstotek cene
02:57
for about one percent of the cost.
62
158000
1000
lahko imate 80 odstotni izkoristek.
02:58
Another nice thing is that a camera can see multiple dots,
63
159000
3000
Dobro je tudi, da lahko kamera zazna več točk
03:01
so this is actually
64
162000
1000
in je s tem
03:02
a multi-touch, interactive whiteboard system as well.
65
163000
2000
omogočen tudi večdotični sistem.
03:04
(Applause)
66
165000
3000
(Aplavz)
03:07
For the second demo, I have this Wii remote
67
168000
2000
Za drugo predstavitev sem krmilnik Wii Remote
03:09
that's actually next to the TV.
68
170000
1000
namestil poleg televizije.
03:11
So it's pointing away from the display,
69
172000
1000
Namesto, da bi ga usmeril proti zaslonu,
03:12
rather than pointing at the display.
70
173000
3000
je v bistvu obrnjen stran.
03:15
And why this is interesting
71
176000
2000
To je zanimivo zato,
03:17
is that if you put on, say, a pair of safety glasses,
72
178000
4000
ker lahko s parom očal,
03:21
that have two infrared dots in them,
73
182000
2000
na katerih sta pritrjeni dve infrardeči diodi,
03:23
what these two dots are essentially going to give you
74
184000
2000
računalniku pošljete
03:25
is, give the computer an approximation of your head location.
75
186000
3000
približek lokacije svoje glave.
03:28
And why this is interesting
76
189000
1000
To pa je zanimivo zato,
03:29
is I have this sort of application running on the computer monitor,
77
190000
3000
ker imam na računalniškem zaslonu zagnano aplikacijo,
03:32
which has a 3D room, with some targets floating in it.
78
193000
3000
ki simulira tridimenzionalen prostor z lebdečimi predmeti.
03:35
And you can see that it looks like a 3D room -- if
79
196000
3000
In kot lahko vidite, je podobno 3-D prostoru,
03:38
you can see -- kind of like a video game, it sort of looks 3D,
80
199000
3000
kot v računalniški igri, nekako deluje tridimenzionalno.
03:41
but for the most part, the image looks pretty flat,
81
202000
2000
Toda slika predvsem deluje ploščata
03:43
and bound to the surface of the screen.
82
204000
2000
in pritrjena na površino zaslona.
03:45
But if we turn on head tracking,
83
206000
5000
Toda, če vključimo sledenje glave,
03:50
the computer can change the image that's on the screen
84
211000
2000
lahko računalnik spremeni sliko na zaslonu
03:52
and make it respond to the head movements.
85
213000
3000
in jo prilagodi gibom glave.
03:55
So let's switch back to that.
86
216000
2000
Zato zdaj vključimo to.
03:57
(Laughter)
87
218000
4000
(Smeh)
04:01
(Applause)
88
222000
10000
(Aplavz)
04:11
So this has actually been a little bit startling
89
232000
3000
Razvijalci iger so se tega
04:14
to the game development community.
90
235000
1000
v bistvu precej ustrašili.
04:15
(Laughter)
91
236000
2000
(Smeh)
04:17
Because this is about 10 dollars of additional hardware
92
238000
3000
Saj vse to predstavlja samo dodatnih 10 dolarjev,
04:20
if you already have a Nintendo Wii.
93
241000
2000
če že imate v lasti igralno konzolo Wii.
04:22
So I'm looking forward to seeing some games,
94
243000
2000
Zato se že veselim nekaterih iger.
04:24
and actually Louis Castle, that's him down there,
95
245000
3000
Louis Castle, tam spodaj sedi,
04:27
last week announced that Electronic Arts,
96
248000
1000
je prejšnji teden oznanil, da bo Electronic Arts,
04:28
one of the largest game publishers, is releasing a game in May
97
249000
4000
eden največjih založnikov iger, maja izdal igro,
04:32
that has a little Easter egg feature
98
253000
1000
v kateri bo "računalniški pirh",
04:33
for supporting this type of head tracking.
99
254000
2000
ki bo podpiral tovrstno naglavno sledenje.
04:36
So -- and that's from less than five months
100
257000
2000
To se je v manj kot petih mesecih
04:38
from a prototype in my lab to a major commercial product.
101
259000
3000
iz prototipa v moji delavnici razvilo v tržni proizvod.
04:41
(Applause)
102
262000
6000
(Aplavz)
04:47
Thank you.
103
268000
3000
Hvala.
04:50
But actually, to me, what's almost more interesting
104
271000
2000
Mi je pa še bolj zanimivo,
04:52
than either of these two products
105
273000
2000
kako so ljudje izvedeli
04:54
is how people actually found out about them.
106
275000
2000
za ta dva izdelka.
04:56
YouTube has really changed the way, or changed the speed,
107
277000
4000
YouTube je močno vplival na to,
05:00
in which a single individual
108
281000
1000
kako hitro lahko posameznik
05:01
can actually spread an idea around the world.
109
282000
2000
razširi idejo po celem svetu.
05:03
You know, I'm doing some research in my lab with a video camera,
110
284000
3000
V enem trenutku razvijam v svoji delavnici video kamero
05:06
and within the first week, a million people had seen this work,
111
287000
3000
in v enem tednu si je moje delo ogledalo že milijon ljudi.
05:10
and literally within days, engineers, teachers and students
112
291000
3000
In dobesedno v nekaj dneh so inženirji, učitelji in učenci
05:13
from around the world, were already posting their own YouTube videos
113
294000
4000
iz celega sveta objavljali lastne posnetke na YouTube-u,
05:17
of them using my system or derivatives of this work.
114
298000
2000
v katerih so uporabljali moj sistem ali nekakšne predelave.
05:19
So I hope to see more of that in the future,
115
300000
3000
Zato upam, da bom v prihodnosti tega videl veliko več,
05:22
and hope online video distribution
116
303000
2000
in upam, da bo raziskovalna skupnost
05:24
to be embraced by the research community.
117
305000
2000
spletno distribucijo videov sprejela.
05:26
So thank you very much.
118
307000
1000
Najlepša hvala.
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.
