What I want to talk to you about today is
0
0
3000
Ono o čemu danas želim govoriti su
00:28
virtual worlds, digital globes, the 3-D Web, the Metaverse.
1
3000
9000
virtualni svjetovi, digitalne kugle, 3D mreža, metaverzum.
00:37
What does this all mean for us?
2
12000
2000
Što sve to nama znači?
00:39
What it means is the Web is going to become an exciting place again.
3
14000
5000
Znači to da će Mreža uskoro ponovno postati uzbudljivo mjesto.
00:44
It's going to become super exciting as we transform
4
19000
3000
Postat će super uzbudljivo dok se transformiramo
00:47
to this highly immersive and interactive world.
5
22000
4000
u taj vrlo zanimljivi i interaktivni svijet,
00:51
With graphics, computing power, low latencies,
6
26000
3000
s grafikom, računalnom snagom, niskom latentnošću,
00:54
these types of applications and possibilities
7
29000
3000
te vrste aplikacija i mogućnosti
00:57
are going to stream rich data into your lives.
8
32000
5000
će unijeti bogate podatke u naše živote.
01:02
So the Virtual Earth initiative, and other types of these initiatives,
9
37000
5000
Incijativa Virtualna zemlja (Virtual Earth) i druge inicijative,
01:07
are all about extending our current search metaphor.
10
42000
6000
se sve bave proširenjem naše trenutne metafore pretrage.
01:13
When you think about it, we're so constrained by browsing the Web,
11
48000
3000
Kad razmislite o tome, tako smo ograničeni u pregledavanju Mreže,
01:16
remembering URLs, saving favorites.
12
51000
3000
pamteći URL-ove, snimajući favorite.
01:19
As we move to search, we rely on the relevance rankings,
13
54000
3000
Kada idemo u potragu, oslanjamo se na rejtinge po značajnosti,
01:22
the Web matching, the index crawling.
14
57000
3000
mrežno podudaranje, puzanje indeksa,
01:25
But we want to use our brain!
15
60000
2000
ali mi želimo koristiti naš mozak!
01:27
We want to navigate, explore, discover information.
16
62000
3000
Želimo navigirati, istraživati, otkrivati informacije.
01:30
In order to do that, we have to put you as a user back in the driver's seat.
17
65000
5000
Kako bismo to mogli, moramo vas korisnike, vratiti za upravljač.
01:35
We need cooperation between you and the computing network and the computer.
18
70000
4000
Trebamo suradnju između vas te računalne mreže i računala.
01:39
So what better way to put you back in the driver's seat
19
74000
4000
Pa ima li boljeg načina da vas vratimo za upravljač
01:43
than to put you in the real world that you interact in every day?
20
78000
3000
od onoga da vas stavimo u stvarni svijet s kojim ste u svakodnevnoj interakciji?
01:46
Why not leverage the learnings that you've been learning your entire life?
21
81000
4000
Zašto ne iskoristiti znanja koja učite cijeli svoj život?
01:50
So Virtual Earth is about starting off
22
85000
3000
Kod Virtualne zemlje se radi o početku,
01:53
creating the first digital representation, comprehensive, of the entire world.
23
88000
5000
stvaranju prve digitalne reprezentacije, potpune, cijeloga svijeta.
01:58
What we want to do is mix in all types of data.
24
93000
3000
Ono što želimo je pomiješati sve vrste podataka.
02:01
Tag it. Attribute it. Metadata. Get the community to add local depth,
25
96000
5000
Označiti ih, obilježiti ih. Metapodaci. Navesti zajednicu da doda lokalnu dubinu
02:06
global perspective, local knowledge.
26
101000
3000
-- globalna perspektiva, lokalno znanje.
02:09
So when you think about this problem,
27
104000
2000
Kad razmislite o tom problemu
02:11
what an enormous undertaking. Where do you begin?
28
106000
4000
vidite da je to ogroman pothvat. Znate, gdje započeti?
02:15
Well, we collect data from satellites, from airplanes,
29
110000
4000
Pa, podatke prikupljamo sa satelita, zrakoplova,
02:19
from ground vehicles, from people.
30
114000
3000
od kopnenih vozila, od ljudi.
02:22
This process is an engineering problem,
31
117000
5000
Ovaj proces je, znate, inženjerski problem,
02:27
a mechanical problem, a logistical problem, an operational problem.
32
122000
4000
mehanički problem, logistički problem, operativni problem.
02:31
Here is an example of our aerial camera.
33
126000
2000
Evo primjera naše kamere u zraku.
02:33
This is panchromatic. It's actually four color cones.
34
128000
3000
Ovo je pankromatski. To su četiri stošca boje.
02:36
In addition, it's multi-spectral.
35
131000
2000
Osim toga, to je i multispektralno.
02:38
We collect four gigabits per second of data,
36
133000
4000
Prikupljamo četiri gigabita podataka u sekundi,
02:42
if you can imagine that kind of data stream coming down.
37
137000
2000
ako možete zamisliti takav tok podatka kako se spušta.
02:44
That's equivalent to a constellation of 12 satellites at highest res capacity.
38
139000
6000
To je ekvivalent konstelaciji od 12 satelita pri najvećoj rezoluciji.
02:50
We fly these airplanes at 5,000 feet in the air.
39
145000
4000
Ovi zrakoplovi lete na preko 1.500 metara u zraku;
02:54
You can see the camera on the front. We collect multiple viewpoints,
40
149000
3000
možete vidjeti kameru na prednjem dijelu. Prikupljamo snimke s različitih gledišta,
02:57
vantage points, angles, textures. We bring all that data back in.
41
152000
6000
različitih visina, kutova, tekstura. Sve te podatke unosimo.
03:03
We sit here -- you know, think about the ground vehicles, the human scale --
42
158000
4000
Sjedimo ovdje – znate, kod kopnenih vozila, u ljudskoj veličini --
03:07
what do you see in person? We need to capture that up close
43
162000
2000
što vidite kad ste osobno tamo? Moramo i to izbliza zabilježiti
03:09
to establish that what it's like-type experience.
44
164000
4000
da utvrdimo to 'kako je tamo' iskustvo.
03:13
I bet many of you have seen the Apple commercials,
45
168000
4000
Kladim se da su mnogi od vas vidjeli reklame za Apple,
03:17
kind of poking at the PC for their brilliance and simplicity.
46
172000
6000
u kojima malo bockaju PC jer su, naravno, oni briljantni i jednostavni.
03:23
So a little unknown secret is --
47
178000
2000
No, mala nepoznata tajna je --
03:25
did you see the one with the guy, he's got the Web cam?
48
180000
4000
jeste li vidjeli onu s tipom koji ima web kameru?
03:29
The poor PC guy. They're duct taping his head. They're just wrapping it on him.
49
184000
4000
Jadnik s PC-jem, oblijepljuju mu glavu trakom, umataju ga.
03:33
Well, a little unknown secret is his brother actually works on the Virtual Earth team.
50
188000
4000
Pa, mala nepoznata tajna je da mu brat, u stvari, radi u timu za Virtualnu zemlju.
03:37
(Laughter). So they've got a little bit of a sibling rivalry thing going on here.
51
192000
5000
(Smijeh). Što znači da tu imaju malo rodbinskog suparništva.
03:42
But let me tell you -- it doesn't affect his day job.
52
197000
2000
No, reći ću vam – to ne utječe na njegov rad.
03:44
We think a lot of good can come from this technology.
53
199000
3000
Mislimo da puno dobrog može proizići iz ove tehnologije.
03:47
This was after Katrina. We were the first commercial fleet of airplanes
54
202000
4000
Ovo je bilo nakon Katrine. Mi smo bili prva komercijalna flota zrakoplova
03:51
to be cleared into the disaster impact zone.
55
206000
3000
kojoj se dopustilo ući u zonu pogođenu katastrofom.
03:54
We flew the area. We imaged it. We sent in people. We took pictures of interiors,
56
209000
5000
Preletjeli smo područje, snimili ga, poslali ljude, fotografirali interijere,
03:59
disaster areas. We helped with the first responders, the search and rescue.
57
214000
4000
pogođena područja. Pomogli smo s prvima koji su se javili, u potrazi i spašavanju.
04:03
Often the first time anyone saw what happened to their house was on Virtual Earth.
58
218000
5000
Mnogi su na Virtualnoj zemlji prvi puta vidjeli što se dogodilo s njihovom kućom.
04:08
We made it all freely available on the Web, just to --
59
223000
2000
Sve smo učinili besplatno dostupnim na mreži, samo da – znate,
04:10
it was obviously our chance of helping out with the cause.
60
225000
4000
očito je to bila naša prilika da pomognemo zajedničkom cilju.
04:14
When we think about how all this comes together,
61
229000
3000
Kad razmišljamo, znate, kako se sve ovo uklapa,
04:17
it's all about software, algorithms and math.
62
232000
4000
sve je u softveru, algoritmima i matematici.
04:21
You know, we capture this imagery but to build the 3-D models
63
236000
3000
Znate, snimimo slike, ali da bismo napravili 3D modele,
04:24
we need to do geo-positioning. We need to do geo-registering of the images.
64
239000
5000
treba nam geo-pozicioniranje. Moramo izvršiti geo-registriranje slika.
04:29
We have to bundle adjust them. Find tie points.
65
244000
2000
Moramo ih skupno prilagoditi. Pronaći povezne točke.
04:31
Extract geometry from the images.
66
246000
3000
Izvući geometriju iz fotografija.
04:34
This process is a very calculated process.
67
249000
4000
Taj je proces sasvim računski.
04:38
In fact, it was always done manual.
68
253000
1000
Zapravo, uvijek ga se obavljalo ručno.
04:39
Hollywood would spend millions of dollars to do a small urban corridor
69
254000
4000
Hollywood je znao potrošiti milijune dolara da napravi mali gradski prolaz
04:43
for a movie because they'd have to do it manually.
70
258000
3000
za neki film, jer su sve morali raditi ručno.
04:46
They'd drive the streets with lasers called LIDAR.
71
261000
2000
Vozili su se ulicama s laserima zvanim LIDAR.
04:48
They'd collected information with photos. They'd manually build each building.
72
263000
4000
Informacije su dobivali s fotografija, a rukom su izrađivali svaku zgradu.
04:52
We do this all through software, algorithms and math --
73
267000
2000
Mi sve to radimo softverom, algoritmima i matematikom,
04:54
a highly automated pipeline creating these cities.
74
269000
3000
visoko automatiziranim postupkom koji stvara gradove.
04:57
We took a decimal point off what it cost to build these cities,
75
272000
3000
Trošak izgradnje tih gradova smo smanjili za decimalno mjesto,
05:00
and that's how we're going to be able to scale this out and make this reality a dream.
76
275000
4000
i zato ćemo biti u stanju ovo uraditi u razmjeru i san pretočiti u stvarnost.
05:04
We think about the user interface.
77
279000
2000
Razmišljamo o korisničkom sučelju.
05:06
What does it mean to look at it from multiple perspectives?
78
281000
3000
Što to znači promatrati nešto iz više perspektiva?
05:09
An ortho-view, a nadir-view. How do you keep the precision of the fidelity of the imagery
79
284000
5000
Orto-pogled, nadir-pogled. Kako zadržati preciznost vjernosti slika
05:14
while maintaining the fluidity of the model?
80
289000
4000
a pritom očuvati i fluidnost modela?
05:18
I'll wrap up by showing you the --
81
293000
2000
Završit ću tako da vam pokažem --
05:20
this is a brand-new peek I haven't really shown into the lab area of Virtual Earth.
82
295000
4000
ovo je nov novcat pogled koji nisam pokazao u laboratoriju Virtualne zemlje.
05:24
What we're doing is -- people like this a lot,
83
299000
3000
Što tu radimo su – ljudi ovo jako vole --
05:27
this bird's eye imagery we work with. It's this high resolution data.
84
302000
3000
ove slike iz ptičje perspektive s kojima radimo. Podaci su u visokoj rezoluciji.
05:30
But what we've found is they like the fluidity of the 3-D model.
85
305000
4000
Ali otkrili smo da ljudi vole fluidnost 3D modela.
05:34
A child can navigate with an Xbox controller or a game controller.
86
309000
4000
Dijete može navigirati pomoću Xbox upravljača, ili igračkog upravljača.
05:38
So here what we're trying to do is we bring the picture and project it into the 3-D model space.
87
313000
5000
Ovdje pokušavamo unijeti sliku i projicirati je u prostor 3D modela.
05:43
You can see all types of resolution. From here, I can slowly pan the image over.
88
318000
6000
Vidite sve vrste rezolucije. Odavde, mogu polako okretati sliku.
05:49
I can get the next image. I can blend and transition.
89
324000
3000
Mogu uzeti slijedeću sliku. Mogu raditi stapanje i prijelaze.
05:52
By doing this I don't lose the original detail. In fact, I might be recording history.
90
327000
5000
Radeći ovo, ne gubim originalne detalje. U stvari, možda snimam povijest.
05:57
The freshness, the capacity. I can turn this image.
91
332000
3000
Svježina, kapacitet. Mogu okrenuti ovu sliku.
06:00
I can look at it from multiple viewpoints and angles.
92
335000
3000
Mogu je promatrati s različitih gledišta i kutova.
06:03
What we're trying to do is build a virtual world.
93
338000
3000
Ono što pokušavamo je izgraditi virtualni svijet.
06:06
We hope that we can make computing a user model you're familiar with,
94
341000
5000
Nadamo se da možemo napraviti korisnički model koji vam je poznat,
06:11
and really derive insights from you, from all different directions.
95
346000
4000
i steći uvide od vas, iz svih mogućih smjerova.
06:15
I thank you very much for your time.
96
350000
2000
Hvala vam lijepa na vašem vremenu.
06:17
(Applause)

ABOUT THE SPEAKER
Stephen Lawler - General manager of Microsoft's Virtual EarthStephen Lawler and the Virtual Earth team have created an addictively interactive 3D world that is poised to reinvent our view of advertising, gaming, weather/traffic reporting, instant messaging and more.
Why you should listen
Microsoft's Stephen Lawler offers a tour of Virtual Earth that not only reveals the power and potential of the software itself, but also gives a global glimpse of the new virtual frontier of digital globes, the 3D Web and the metaverse.
Lawler also explores the enormous effort it takes to create the fluid blending and shifting between the multiple views and resolutions of Virtual Earth. From the satellites and airplanes that gather photo data for a top-down view to the ground vehicles and headgear-wearing pedestrians who canvas the ground for an eye-level perspective -- all of it represents a monumental effort of logistics and mechanics.
