So, as researchers, something that we often do is use immense resources

But what actually interests me a lot more
20
70382

이 μ‘°μ’…κΈ° 맨 끝에

is the fact that in the tip of each controller

is a relatively high-performing infrared camera.

이게 μ™œ μœ μš©ν•œμ§€ 두 가지 이유λ₯Ό λ³΄μ—¬λ“œλ¦¬μ£ .

So here, I have my computer set up with the projector,

82243
2904
κ·Έ μœ„μ— Wii μ‘°μ’…κΈ°κ°€ μžˆμŠ΅λ‹ˆλ‹€.
01:25
and I have a Wii Remote sitting on top of it.
25
85171
2357
예λ₯Όλ“€μ–΄ 학ꡐ라고 해보죠.
01:27
And, for example, if you're in a school that doesn't have a lot money,

μ•„λ‹˜ μ—¬λŸ¬λΆ„ 사무싀이라 생각해도 λ˜κ³ μš”.
01:32
or if you're in an office environment, and you want an interactive whiteboard,
28
92885

μ–΄μ¨Œλ“  κ±°κΈ°μ„œ μ „μžμΉ νŒμ΄ ν•˜λ‚˜ ν•„μš”ν•˜λ‹€ 치면

ν•„μš”ν•œ μž₯λΉ„κ°€ ν•œκ°€μ§€ 더 μžˆμŠ΅λ‹ˆλ‹€.
01:43
Now, this requires another piece of hardware,
31

적외선 νŽœμΈλ°μš”.
01:47
which is this infrared pen.

01:51
with a quick trip to the Radio Shack.
34

1832
배터리도 μžˆκ΅¬μš”. 적외선 전ꡬ ON/OFF μŠ€μœ„μΉ˜κ°€ 있고..
01:53
It's got a battery, a button and an infrared LED --
35
113287
2558
μ΄λ ‡κ²Œ ν‚€λ©΄.. λˆˆμ—” μ•ˆλ³΄μž…λ‹ˆλ‹€.
01:55
you guys can't see it --

근데 사싀 λ²„νŠΌμ„ λˆ„λ₯΄λ©΄ μΌœμ§‘λ‹ˆλ‹€. μ•ˆλ³΄μ—¬λ„μš”.
01:57
but it turns on whenever I push the button.

이게 뭐냐면, κ·ΈλŸ¬λ‹ˆκΉŒ μ œκ°€ 이 ν”„λ‘œκ·Έλž¨μ„ ν•œλ²ˆ 돌렀보죠.
01:59
Now, what this means is that if I run this piece of software,
38
119306
4538
카메라가 적외선 점을 λ΄…λ‹ˆλ‹€.
02:03
the camera sees the infrared dot,
39
123868
4413
그럼 우린 이제 μΉ΄λ©”λΌμ—μ„œ ν™”μ†Œμ˜ μœ„μΉ˜λ₯Ό λ”°μ„œ
02:08
and I can register the location of the camera pixels

ν”„λ‘œμ ν„°μ— λΏŒλ¦¬λŠ”κ±°μ£ . μ „μžμΉ νŒμ΄ λλ„€μš”.
02:12
to the projector pixels.
41
132514
1143
02:13
And now this is like an interactive whiteboard surface.
42
133681

So for about $50 of hardware, you can have your own whiteboard.

μ•„λ¬΄λž˜λ„ 이 방식에 ν•œκ³„κ°€ μžˆλŠ” 것이 μ‚¬μ‹€μž…λ‹ˆλ‹€.

there are some limitations of this approach.

ν•˜μ§€λ§Œ κ·Έλž˜λ„ 1νΌμ„ΌνŠΈμ˜ λΉ„μš©λ§ŒμœΌλ‘œ

02:58
Another nice thing is that a camera can see multiple dots,
59
178914
2778
κ·Έλž˜μ„œ μ΄λ ‡κ²Œ
03:01
so this is actually a multi-touch, interactive whiteboard system as well.

2263
예λ₯Όλ“€μ–΄ 적외선 점이 λ‘κ°œ 찍힌 μ•ˆκ²½μ„ μ“°λ©΄,

71
213082
2532
κ·Έλƒ₯ 보면 3Dκ°™κΈ΄ ν•œλ°..
03:35
And you can see that it looks like a 3D room.
72
215638
2239
03:37
kind of like a video game, it sort of looks 3D,
73
217901
3347

ν•˜μ§€λ§Œ μ΄λ ‡κ²Œ ν—€λ“œ νŠΈλž˜ν‚Ήμ„ ν‚€λ©΄..

2100
컴퓨터가 μ΄λ ‡κ²Œ ν™”λ©΄μ˜ 각도λ₯Ό λ°”κΎΈλŠ” κ²λ‹ˆλ‹€.

and make it respond to the head movements.
78
233859

λ’€λ‘œ κ°€λ³ΌκΉŒμš”..
03:55
So let's switch back to that.
