In 1962, Buckminster Fuller
0
1000
2000
V roku 1952 predstavil Buckminister Fuller
00:21
presented the particularly audacious proposal for the Geoscope.
1
3000
4000
obzvlášť smelý návrh Geoskopu.
00:25
It was a 200-foot diameter geodesic sphere
2
7000
3000
Bola to guľa s priemerom 61 metrov,
00:28
to be suspended over the East River in New York City, in full view of the United Nations.
3
10000
5000
ktorá mala visieť nad prielivom East River v New Yorku a malo ju byť vidno zo sídla OSN.
00:33
It was a big idea, for sure, and it was one that he felt could truly inform
4
15000
6000
Bola to určite veľkolepá myšlienka, o ktorej si myslel, že by mohla naozaj informovať
00:39
and deeply affect the decision making of this body
5
21000
4000
a hlboko ovplyvniť rozhodovací proces tejto organizácie
00:43
through animations of global data, trends
6
25000
4000
pomocou animácií globálnych dát, trendov
00:47
and other information regarding the globe, on this sphere.
7
29000
4000
a ostatných informácií, ktoré sa týkali našej planéty.
00:51
And today, 45 years later,
8
33000
3000
Dnes, po 45 rokoch,
00:54
we clearly have no less need for this kind of clarity and perspective,
9
36000
3000
evidentne rovnako veľmi potrebujeme podobnú zrozumiteľnosť a perspektívu,
00:57
but what we do have is improved technology.
10
39000
3000
avšak máme vylepšenú technológiu.
01:00
Today we don't need one million light bulbs to create a spherical display.
11
42000
3000
Dnes nepotrebujeme milión žiaroviek, aby sme vytvorili guľovité zobrazenie.
01:03
We can use LEDs.
12
45000
2000
Môžeme použiť LED diódy.
01:05
LEDs are smaller, they're cheaper, they're longer lasting, they're more efficient.
13
47000
5000
LED diódy sú menšie, lacnejšie, vydržia dlhšie a sú účinnejšie.
01:10
Most importantly for this, they're faster.
14
52000
2000
Najdôležitejšie však je, že sú rýchlejšie.
01:12
And this speed, combined with today's high-performance micro-controllers,
15
54000
4000
Táto rýchlosť, skombinovaná s dnešnými vysokovýkonnými mikroovládačmi,
01:16
allows us to actually simulate, in this piece,
16
58000
3000
nám v tomto prípade umožnila naozaj simulovať
01:19
over 17,000 LEDs -- using just 64.
17
61000
4000
viac ako 17 000 LED diód s pomocou len 64.
01:24
And the way this happens is through the phenomenon of persistence of vision.
18
66000
4000
Deje sa tak vďaka fenoménu doznievania obrazu na sietnici oka po skončení vizuálneho vnemu.
01:28
But as this ring rotates at about 1,700 rpm -- that's 28 times per second.
19
70000
4000
Tento prstenec sa otáča rýchlosťou 1700 otáčok za minútu, čo je 28-krát za sekundu.
01:33
The equator's speed is actually about 60 miles per hour.
20
75000
3000
Rýchlosť na jeho rovníku je približne 96 km/h.
01:36
There are four on-board micro-controllers
21
78000
2000
Sú na ňom 4 mikroovládače,
01:38
that, each time this ring rotates
22
80000
3000
ktoré zakaždým, keď ich tento prstenec otočí
01:41
it, as it passes the rear of the display,
23
83000
2000
a prejdú zadnou časťou zobrazenia,
01:43
it picks up a position signal.
24
85000
2000
zachytia signál o pozícii
01:45
And from that, the on-board micro-controllers
25
87000
2000
a z neho môžu zabudované mikoovládače
01:47
can extrapolate the position of the ring at all points around the revolution
26
89000
5000
odvodiť pozíciu prstenca vo všetkých bodoch jeho otáčania
01:52
and display arbitrary bitmap images and animations.
27
94000
3000
a zobrazovať ľubovoľnú bitmapu obrazov a animácií.
01:55
But this is really just the beginning.
28
97000
3000
Je to však naozaj len začiatok.
01:58
In addition to higher resolution versions of this display,
29
100000
3000
Ja a môj otec pracujeme nielen na verzii tohto zobrazenia s vyšším rozlíšením,
02:01
my father and I are working on a new patent-pending design
30
103000
3000
ale aj na novom dizajne, ktorý je v patentovom schvaľovacom procese
02:04
for a fully volumetric display using the same phenomenon.
31
106000
3000
a ktorý umožňuje celovolumetrické zobrazenie pomocou rovnakého fenoménu.
02:07
It achieves this by rotating LEDs about two axes.
32
109000
3000
Dosahuje ho otáčaním LED diód okolo dvoch osí.
02:10
So as you can see here, this is a, eleven-inch diameter circuit board.
33
112000
3000
Tak, ako tu môžete vidieť, ide o dosku plošných spojov s priemerom 29 cm.
02:13
These blocks represent LEDs.
34
115000
2000
Tieto bloky predstavujú LED diódy.
02:15
And so you could see that as this disc rotates about this axis,
35
117000
4000
Mohli by ste tak vidieť, že počas toho, ako sa tento disk otáča okolo tejto osi,
02:19
it will create a disc of light that we can control.
36
121000
3000
vytvára disk sveta, ktorý dokážeme ovládať.
02:22
That's nothing new: that's a propeller clock;
37
124000
2000
Nie je to nič nové. Sú to vrtuľové hodiny.
02:24
that's the rims that you can buy for your car.
38
126000
3000
Sú to rámy kolies, ktoré si môžete kúpiť do svojho auta.
02:27
But what is new is that, when we rotate this disc about this axis,
39
129000
5000
Nové je však to, že keď tento svetelný disk otáčame okolo tejto osi,
02:32
this disc of light actually becomes a sphere of light.
40
134000
3000
stane sa z neho svetelná guľa.
02:35
And so we can control that with micro-controllers
41
137000
2000
Pomocou mikroovládačov ju môžeme ovládať
02:37
and create a fully volumetric, three-dimensional display with just 256 LEDs.
42
139000
6000
a vytvoriť celovolumetrické trojrozmerné zobrazenie len s 256 LED diódami.
02:43
Now this piece is currently in process --
43
145000
2000
Momentálne sa na ňom pracuje
02:45
due out in May -- but what we've done is we've put together a small demo,
44
147000
5000
a malo by byť hotové v máji. Dali sme však dohromady malú prezentáciu,
02:50
just to show the geometric translation of points into a sphere.
45
152000
4000
aby sme vám ukázali geometrický prevod bodov do gule.
02:54
I've got a little video to show you,
46
156000
2000
Ukážem vám malé video,
02:56
but keep in mind that this is with no electronic control,
47
158000
4000
ale nezabúdajte, že tu nie je žiadne elektronické ovládanie
03:00
and this is also with only four LEDs.
48
162000
2000
a že to má len 4 LED diódy.
03:02
This is actually only about 1.5 percent of what the final display will be in May.
49
164000
3000
Je to len približne 1,5 percenta toho, ako bude v máji vyzerať konečné zobrazenie.
03:05
So, take a look.
50
167000
2000
Pozrite sa na to.
03:09
And here you can see it's rotating about the vertical axis only, creating circles.
51
171000
4000
Tu vidíte otáčanie len okolo vertikálnej osi a vytváranie kruhov.
03:17
And then, as the other axis kicks in,
52
179000
2000
Potom naskočí druhá os
03:19
those actually blur into a volume.
53
181000
2000
a obe sa rozmažú tak, že tvoria objem.
03:21
And the shutter speed of the camera
54
183000
2000
Kvôli rýchlosti uzáveru kamery
03:23
actually makes it slightly less effective in this case.
55
185000
3000
to vlastne v tomto prípade vyzerá trochu menej pôsobivo.
03:26
But this piece is due out in May.
56
188000
2000
Malo by sa to však objaviť v máji.
03:28
It'll be on display at the Interactive Telecommunications Spring Show
57
190000
3000
Budeme to predvádzať na výstave Interactive Telecommunications Spring Show
03:31
in Greenwich Village in New York City -- that's open to the public,
58
193000
2000
v Greenwich Village v New Yorku. Je otvorená pre verejnosť
03:33
definitely invite you all to come and attend -- it's a fantastic show.
59
195000
4000
a určite vás všetkých pozývam na jej návštevu. Je to fantastická výstava.
03:37
There are hundreds of student innovators with fantastic projects.
60
199000
4000
Sú tam stovky študentov-inovátorov s úžasnými projektmi.
03:41
This piece, actually, will be on display
61
203000
2000
Tento kus budete môcť vidieť
03:43
down in the Sierra Simulcast Lounge
62
205000
2000
dole v hale Sierra Simulcast Lounge
03:45
in the breaks between now and the end of the show.
63
207000
2000
počas prestávok odteraz až do konca tohto podujatia.
03:47
So I'd love to talk to you all, and invite you
64
209000
2000
Rád by som sa s vami všetkými porozprával a pozval vás,
03:49
to come down and take a closer look.
65
211000
2000
aby ste prišli a pozreli sa naň bližšie.
03:51
It's an honor to be here. Thanks very much.
66
213000
2000
Je to česť byť tu. Ďakujem vám veľmi pekne.
03:53

ABOUT THE SPEAKER
Nick Sears - InventorWorking with his father, Ron Sears, Nick Sears is designing and building the Orb, a rotating LED display that uses persistence of vision to produce moving images in 3D space.
Why you should listen
Nick Sears is a classic tinkerer -- his resume lists jobs that run the gamut from writing a mobile messaging framework to building a DC-DC switching voltage regulator. Along with his dad, Ron Sears, he's got a pretty neat father-son project going on: the Orb.
It's inspired by Buckminster Fuller's 1962 proposal for the Geoscope, which called for "a 200-foot-diameter sphere covered with 10 million computer-controlled light sources to be suspended over the East River in full view of the United Nations." But by making the sphere spin, the Sears realized, they could use persistence of vision and LEDs to create a bright display with a three-dimensional effect using far fewer light sources.
Sears is now a student in the Interactive Telecommunications Program at NYU. He and his father presented the Orb version 2 at Coachella in 2008 and continue to tinker with it.
