為何要聽他演講:
若要瞭解Johnny Lee,只需到訪他的網站就夠了,除了他的Wii 遙控 HACKS被 Digg 票選為第一名的恆時科技示範之外,你還可以一覽他心智所有遊歷過的領域:文字設計、攝影、都市更新等,更不必提他在Little Great Ideas 中的有趣副業,或像催眠般的創意填詞「___ will ___ you」。
 
自從他在卡內基‧美隆大學人類-電腦互動學院取得博士學位後,即加入微軟,負責Project Natal─Xbox 360的無控制感應裝置團隊。

身為研究人員,我們常利用很多的資源來發掘特定物件的潛能,或達成一定的目標,而這也是科學進步或探索未知可能性的要素,但不幸的是只有非常少數的人可以參與這項科技探索或從中受益,而這激勵我且讓我對自己的研究更感興奮,因為我看到了一個很小的機會可以大大的改變這種不公平的資源分配,且讓更廣大的人群可以分享科技所帶來的便利。
 
 
現在,我要開始展示兩支具體實現上述理念的熱門影片,過程中我會使用任天堂出品的Wii遙控器,有些人可能不曉得這裝置是啥玩意,這是一支40美元的電玩遙控器,它的主打強項是能進行動態感應遙控,意即你可以真的像揮動網球拍或打棒球一樣的玩遊戲,但真正吸引我的是,事實上這支遙控器的頂端是一個相對高性能的紅外線相機,現在我將展示兩個示範,看看它為何是有用的,現在我的電腦和投影機都已裝好,上頭還有Wii遙控器,舉例而言,如果您是學校人員,而且校方的經費不多,這種學校很多,或者您是在辦公室環境上班,且正需要一塊互動式白板,一般而言,都需要花上個二、三千元美金,我現在要展示的是如何用Wii遙控器來取而代之。
 
 
另外還需要的硬體是一支紅外線筆,您也可以到Radio Shack花五美元買材料自己做一個,內含電池、按鈕及紅外線LED,它打開了,您們看不到-我只要按下按鈕即可打開,現在,如果我開始執行這個軟體,相機就能看見紅外線光點,我就可以標出相機映像點位置,對應到投影機的映像點位置,這就成了一個互動式白板了(掌聲),只要50美元的硬體,您就能擁有屬於自己的互動式白板,這是Adobe Photoshop(掌聲)。
 
 
〔見鬼!〕謝謝(笑聲)
 
 
這套軟體已經放到我的網站上供大家免費下載,三個月來這已是眾所皆知,有超過五十萬次的下載,現在,全世界的師生都已開始使用這套軟體(掌聲),我聲明一下,雖然這只需要50美元且有些限制的地方,但功能上有80%的相似度,您卻只需花1%的費用,另一項優勢是相機能同時辨認出多點位置,所以這也是一套多點觸控的互動式白板系統。(掌聲)
 
 
第二個展示中,我將Wii遙控器放在電視旁邊,所以是指向螢幕外,而非指向螢幕,這個應用有趣的地方是,啊,在這兒,如果您載上一付裝有兩點紅外線感應點的安全護鏡,這兩個感應點能讓電腦辨識出您頭部的位置,有趣的是電腦螢幕上正在執行的程式,即一個3D空間中有一些漂浮的目標物,你可以看到,它看起來像3D 空間,有點像3D遊戲,但這些影像看起來大多是很平地貼在螢幕表面,可是,如果我們把頭部追蹤器打開,電腦就能改變螢幕上的影像,讓它隨著頭部的動作產生互動,所以,讓我們回頭來看看。
 
(笑聲)
(掌聲)
 
這確實有點震驚了遊戲開發社群。
 
(笑聲)
 
因為如果您擁有任天堂Wii,則只需額外花10美元的硬體費用,其實,我是想將它結合到遊戲的領域,碰巧現在台下的Roules Castle在上週宣布,全國最大遊戲發行商之一的美商藝電將在五月發表一款遊戲,特色是能支援頭部追蹤的隱藏功能,而從我實驗室中的原型到成為熱門商業化產品只花了不到五個月的時間(掌聲),謝謝。


但事實上讓我更感興趣的,不是這兩個產品,而是人們如何發現它們,You Tube 確實改變了個人點子傳播到全世界的方法與速度,我只不過是一位在實驗室中用攝影機作研究的人,但頭一週就有上百萬人看到我所做的,短短幾天內,全球的工程師、老師與學生,開始在YouTube上發表使用或變化這套系統的影片,我希望將來能看到更多這樣的影片,同時也希望線上影片傳播能廣為研究社群所接納,感謝聆聽。
 
(掌聲)

About this talk

Building sophisticated educational tools out of cheap parts, Johnny Lee demos his cool Wii Remote hacks, which turn the $40 video game controller into a digital whiteboard, a touchscreen and a head-mounted 3-D viewer.

About Johnny Lee

Transcript

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 sort of creates this unfortunate situation where a tiny, tiny fraction of the world can actually participate in this exploration or can benefit from that technology. And something that motivates me, and what 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.

And I'm going to show you two videos that have gotten a lot of attention recently that I think embody this philosophy. And they actually use the Nintendo Wii remote. Now, for those of you who aren't familiar with this device, it's a 40 dollar video game controller. And it's mostly advertised for it's motion sensor 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.

So here I have my computer setup 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, which is 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 what I'm going to show you how to do is 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 essentially got a battery, a button and an infrared LED, and it turns on -- 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 a whiteboard surface. (Applause) So for about 50 dollars of hardware, you can have your own whiteboard. This is Adobe Photoshop. (Applause) Thank you. (Laughter)

Now, the software for this I've actually put on my website and have let people download it for free. And in the three months that 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. (Applause) I want to quickly say that although it does do it for 50 dollars, there are some limitations of this approach. But you get about 80 percent of the way there, for about 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. (Applause)

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, what these two dots are essentially going to give you is 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 if you can see, 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. (Laughter) (Applause)

So this has actually been a little bit startling to the game development community. (Laughter) 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. So -- and that's from less than five months from a prototype in my lab to a major commercial product. (Applause) Thank you.

But actually, to me, what's almost more interesting than either of these two products, 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. You know, 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. So thank you very much. (Applause)
