So, as researchers, something that we often do is use immense resources to achieve certain capabilities, or achieve certain goals. And this is essential to the progress of science, or exploration of what is possible. But it creates this unfortunate situation where a tiny, tiny fraction of the world can actually participate in this exploration or can benefit from that technology. Something that motivates me, and gets me really excited about my research, is when I see simple opportunities to drastically change that distribution and make the technology accessible to a much wider percentage of the population.
Raziskovalci pogosto porabimo veliko sredstev, da bi dosegli določeno zmogljivost ali določene cilje. To je bistvenega pomena za napredek znanosti in raziskovanje novih potencialov. Toda hkrati pa ustvari to nerodno situacijo, kjer se lahko le zelo majhen del sveta udeleži teh raziskav ali koristi te tehnologije. Pri moji raziskavi me še posebej spodbudi in navduši, ko odkrijem enostavne priložnosti, ki lahko spremenijo širjenje in dostop do tehnologij na veliko večji delež svetovnega prebivalstva.
Pokazal vam bom dva posnetka,
I'm going to show you two videos that have gotten a lot of attention that I think embody this philosophy. And they actually use the Nintendo Wii Remote. For those of you who aren't familiar with this device, it's a $40 video game controller. And it's mostly advertised for its motion-sensing capabilities: so you can swing a tennis racket, or hit a baseball bat. But what actually interests me a lot more is the fact that in the tip of each controller is a relatively high-performing infrared camera. And I'm going to show you two demos of why this is useful.
ki sta v zadnjem času zelo popularna in po mojem mnenju poosebljata to idejo. Pri tem bomo uporabili Nintendov krmilnik Wii Remote. Za tiste, ki s to napravo niste seznanjeni, to je igralni plošček, ki stane 40 dolarjev. Njegova posebnost je zmožnost zaznavanja gibov. Tako lahko v igri zamahnete tenis lopar ali palico za baseball. Meni pa je veliko bolj zanimivo to, da je v konici vsakega igralnega ploščka vgrajena relativno visokozmogljiva infrardeča kamera. Z dvema predstavitvama vam bom pokazal, zakaj je to uporabno.
So here, I have my computer set up with the projector, and I have a Wii Remote sitting on top of it. And, for example, if you're in a school that doesn't have a lot money, probably a lot of schools, or if you're in an office environment, and you want an interactive whiteboard, normally these cost about two to three thousand dollars. So I'm going to show you how to create one with a Wii Remote. Now, this requires another piece of hardware, which is this infrared pen. You can probably make this yourself for about five dollars with a quick trip to the Radio Shack. It's got a battery, a button and an infrared LED -- you guys can't see it -- but it turns on whenever I push the button. Now, what this means is that if I run this piece of software, the camera sees the infrared dot, and I can register the location of the camera pixels to the projector pixels. And now this is like an interactive whiteboard surface.
Tukaj imam svoj računalnik priklopljen na projektor in na projektorju leži krmilnik Wii Remote. Če ste na primer v šoli z nizkim proračunom, katerih je najbrž veliko, ali pa ste v pisarni in bi želeli imeti interaktivno tablo, potem te ponavadi stanejo okrog 2.000 do 3.000 dolarjev. Zato vam bom pokazal, kako si jo lahko izdelate sami s pomočjo krmilnika Wii Remote. Poleg tega boste potrebovali tudi flomaster z infrardečo diodo v konici. Za ceno 5 dolarjev ga lahko sestavite sami doma s hitrim obiskom v bližnjo računalniško trgovino. Sestavljen je iz baterije, gumba in infrardeče diode, ki se vključi, vi tega ne vidite, ampak vključi se, ko pritisnete na gumb. To pomeni, da lahko kamera z zagonom tega programa zazna infrardečo diodo in uskladi položaj točk kamere s točkami projektorja in postane interaktivna tabla. (Aplavz)
(Applause)
Tako lahko imate za 50 dolarjev lastno interaktivno tablo.
So for about $50 of hardware, you can have your own whiteboard. This is Adobe Photoshop.
To je Adobe Photoshop. (Aplavz)
(Applause)
Hvala.
Thank you.
(Smeh)
(Laughter)
Ta program je naložen na moji spletni strani
The software for this I've actually put on my website and have let people download it for free. In the three months this project has been public, it's been downloaded over half a million times. So teachers and students all around the world are already using this.
in si ga lahko naložite brezplačno. Po treh mesecih od objave projekta v javnost je bilo opravljenih več kot pol milijona prenosov. Torej program že uporabljajo učitelji in učenci po celem svetu. (Aplavz)
(Applause)
Rad bi samo dodal, da čeprav je zmožen vsega tega za le 50 dolarjev,
Although it does do it for 50 dollars, there are some limitations of this approach. You get about 80 percent of the way there, for one percent of the cost. Another nice thing is that a camera can see multiple dots, so this is actually a multi-touch, interactive whiteboard system as well.
je uporaba vseeno nekoliko omejena. Toda za le en odstotek cene lahko imate 80 odstotni izkoristek. Dobro je tudi, da lahko kamera zazna več točk in je s tem omogočen tudi večdotični sistem.
(Applause)
(Aplavz)
For the second demo, I have this Wii Remote that's actually next to the TV. So it's pointing away from the display, rather than pointing at the display. And why this is interesting is that if you put on, say, a pair of safety glasses, that have two infrared dots in them, they are going to give the computer an approximation of your head location. And why this is interesting is I have this sort of application running on the computer monitor, which has a 3D room, with some targets floating in it. And you can see that it looks like a 3D room. kind of like a video game, it sort of looks 3D, but for the most part, the image looks pretty flat, and bound to the surface of the screen. But if we turn on head tracking -- the computer can change the image that's on the screen and make it respond to the head movements. So let's switch back to that.
Za drugo predstavitev sem krmilnik Wii Remote namestil poleg televizije. Namesto, da bi ga usmeril proti zaslonu, je v bistvu obrnjen stran. To je zanimivo zato, ker lahko s parom očal, na katerih sta pritrjeni dve infrardeči diodi, računalniku pošljete približek lokacije svoje glave. To pa je zanimivo zato, ker imam na računalniškem zaslonu zagnano aplikacijo, ki simulira tridimenzionalen prostor z lebdečimi predmeti. In kot lahko vidite, je podobno 3-D prostoru, kot v računalniški igri, nekako deluje tridimenzionalno. Toda slika predvsem deluje ploščata in pritrjena na površino zaslona. Toda, če vključimo sledenje glave, lahko računalnik spremeni sliko na zaslonu in jo prilagodi gibom glave. Zato zdaj vključimo to.
(Laughter)
(Smeh)
(Applause)
(Aplavz)
So this has actually been a little bit startling to the game-development community.
Razvijalci iger so se tega v bistvu precej ustrašili.
(Laughter)
(Smeh)
Because this is about 10 dollars of additional hardware if you already have a Nintendo Wii. So I'm looking forward to seeing some games, and actually Louis Castle, that's him down there, last week announced that Electronic Arts, one of the largest game publishers, is releasing a game in May that has a little Easter egg feature for supporting this type of head tracking. And that's from less than five months from a prototype in my lab to a major commercial product.
Saj vse to predstavlja samo dodatnih 10 dolarjev, če že imate v lasti igralno konzolo Wii. Zato se že veselim nekaterih iger. Louis Castle, tam spodaj sedi, je prejšnji teden oznanil, da bo Electronic Arts, eden največjih založnikov iger, maja izdal igro, v kateri bo "računalniški pirh", ki bo podpiral tovrstno naglavno sledenje. To se je v manj kot petih mesecih iz prototipa v moji delavnici razvilo v tržni proizvod.
(Applause)
(Aplavz)
Thank you.
Hvala.
(Applause)
Mi je pa še bolj zanimivo,
But actually, to me, what's almost more interesting than either of these two projects is how people actually found out about them. YouTube has really changed the way, or changed the speed, in which a single individual can actually spread an idea around the world. I'm doing some research in my lab with a video camera, and within the first week, a million people had seen this work, and literally within days, engineers, teachers and students from around the world were already posting their own YouTube videos of them using my system or derivatives of this work. So I hope to see more of that in the future, and hope online video distribution to be embraced by the research community.
kako so ljudje izvedeli za ta dva izdelka. YouTube je močno vplival na to, kako hitro lahko posameznik razširi idejo po celem svetu. V enem trenutku razvijam v svoji delavnici video kamero in v enem tednu si je moje delo ogledalo že milijon ljudi. In dobesedno v nekaj dneh so inženirji, učitelji in učenci iz celega sveta objavljali lastne posnetke na YouTube-u, v katerih so uporabljali moj sistem ali nekakšne predelave. Zato upam, da bom v prihodnosti tega videl veliko več, in upam, da bo raziskovalna skupnost spletno distribucijo videov sprejela. Najlepša hvala.
So thank you very much.
(Aplavz)
