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.
Kao inovatori često koristimo razne resurse u ostvarenju cilja. To je napredak u znanosti ili izučavanje mogućeg. No događa se da često, tek mali dio zajednice može sudjelovati u samom istraživanju ili imati korist od dobivene tehnologije. Ono što me motivira, i što istraživanje čini uzbudljivim jest prilika otkrivanja rješenja koja drastično mijenjaju odnose i čine tehnologiju pristupačnom mnogo većem postotku populacije.
Pokazat ću vam nešto
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.
što trenutno privlači pažnju i ima u sebi novi pristup. Nintendo Wii daljinski upravljač (igraća konzola). Za one koji nisu upoznali ovaj uređaj, govorim o upravljaču za video igre. Poznat po svojoj mogućnosti praćenja pokreta, oponašajući pokrete u igrama. No ono što je privuklo moju pažnju je činjenica da je u svaki upravljač ugrađena kvalitetna infracrvena kamera. Pokazat ću vam mogućnost uporabe.
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.
Računalo je spojeno sa projektorom na kojem se nalazi daljinski upravljač. Primjerice, u školi ste koja nema dovoljno sredstava, ili radite u uredskom okruženju, i potrebna vam je pametna ploča, čija se cijena kreće oko 10 000 kuna. Ono što ću vam pokazati je kako iskoristiti Wii daljinski kao pametnu ploču. Potreban nam je još jedan dio, a to je infracrvena olovka. Nju je moguće izraditi za otprilike 25 kuna kupnjom potrebnog materijala. Trebate bateriju, prekidač i IC LED diodu, koja se pali i pali se pritiskom prekidača. Kada pokrenem aplikaciju kamera će uočiti infracrvenu točku, i zabilježiti položaj piksela kamere i usporediti sa pikselima projektora. Dobili smo površinu pametne ploče. (Pljesak)
(Applause)
Za 300 kuna dobili ste pametnu ploču.
So for about $50 of hardware, you can have your own whiteboard. This is Adobe Photoshop.
Ovo je Adobe Photoshop. (Pljesak)
(Applause)
Hvala vam.
Thank you.
(Smijeh)
(Laughter)
Aplikacija za ovo na mojoj je internet stranici
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.
i možete je preuzeti besplatno. U tri mjeseca koliko je ovaj projekt dostupan zabilježeno je preko 500 000 preuzimanja. Učitelji i učenici diljem svijeta već je koriste. (Pljesak)
(Applause)
Iako funkcionira za nekih 300 kuna,
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.
ovaj pristup ima svojih ograničenja. No iskoristivost od 80% usporedite sa oko 1% stvarne cijene pametne ploče. Kamera bilježi više točaka, i moguća je uporaba više korisnika pametne ploče istovremeno.
(Applause)
(Pljesak)
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.
Sljedeća demonstracija uključuje Wii daljinski koji se nalazi uz televizor. Usmjeren je suprotno od ekrana, umjesto prema njemu. Ovo je zanimljivo stoga što stavimo li npr. okvir naočala, sa dvije infracrvene točke na njemu, ono što ćemo dobiti je da računalo procijeni položaj naše glave. Ono što je zanimljivo je aplikacija vidljiva na ekranu monitora, i prikazuje 3D sobu sa plutajućim objektima. Poput video igre, no daje dojam plošnosti, priljubljena uz površinu ekrana. Uključimo li praćenje pokreta glave, promijenit će se slika na ekranu pri pomaku glave. Vratimo se na trenutak.
(Laughter)
(Smijeh)
(Applause)
(Pljesak)
So this has actually been a little bit startling to the game-development community.
Ovo je vjerojatno uzbudljivo proizvođačima igara.
(Laughter)
(Smijeh)
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.
Jer su troškovi neznatno veći ako već imate Nintendo Wii. Stoga očekujem igre, a budući da je Louis Castle ovdje, i najavio je da Electronic Arts, u svibnju objavljuje igru koja kao posebno iznenađenje podržava sustav praćenja pokreta glave. Dakle, u vremenskom periodu od 5 mjeseci od prototipa u laboratoriju do gotovog proizvoda.
(Applause)
(Pljesak)
Thank you.
Hvala vam.
(Applause)
Ono što je zanimljivije
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.
od oba ova proizvoda je način na koji su ljudi saznali za njih. YouTube je utjecao na način i brzinu, kojom pojedinac širi svoju ideju svijetom. Sve što radim, snimam i u prvom tjednu, mnogi su vidjeli moj rad, i u nekoliko dana, inženjeri, učitelji i učenici iz cijelog svijeta, objavljuju svoje radove koristeći moj sustav ili modifikaciju istog. Stoga očekujem više takvih pokušaja, s nadom da će mrežnu video distribuciju prihvatiti i istraživačka zajednica. Zahvaljujem na pažnji.
So thank you very much.
(Pljesak)
