这种操作工具更加独立，更加灵敏，能彼此感知，感知任何细微的移动，所以我们可以使用这种工具尝试一些新的有趣的互动。
And as these tools become more physical, more aware of their motion, aware of each other, and aware of the nuance of how we move them, we can start to explore some new and fun interaction styles.
现在，我就来演示一些简单的。
So, I'm going to start with some simple examples.
这块Siftable有映像配置，如果我把它向一侧倾斜，那么它所显示的画面也朝这边倾斜，如果我把它朝反方向倾斜，那么图像也朝反方向倾斜。
This Siftable is configured to show video, and if I tilt it in one direction, it'll roll the video this way; if I tilt it the other way it rolls it backwards.
而且这些Siftables能互相感知。
And these interactive portraits are aware of each other.
如果把它们一个挨一个摆好，有趣的现象就会发生。
So if I put them next to each other, they get interested.
如果把它们随意一堆，他们也会察觉到，那就会有点儿混乱。
If they get surrounded, they notice that too, they might get a little flustered.
它们还能感知彼此的移动和倾斜。
And they can also sense their motion and tilt.
我们发现一个有趣的互动—我们可以通过一些常用的手势和Siftables进行互动，比如象倒液体那样把颜色从一块Siftable倒入另一块Siftable.
One of the interesting implications on interaction, we started to realize, was that we could use everyday gestures on data, like pouring a color the way we might pour a liquid.
我们来看这个演示，这有三块设置成油漆桶模式的Siftables,我们可以把这些桶里的颜色倒入中间的那个，把颜色混在一起.
So in this case, we've got three Siftables configured to be paint buckets and I can use them to pour color into that central one, where they get mixed.
如果倒多了，可以再倒回去一些。
If we overshoot, we can pour a little bit back.
Siftables还有学习机的功能，可以用来学语言、算算术等—我们希望通过这些功能让学习变得快捷，更快看到结果。
There are also some neat possibilities for education, like language, math and logic games where we want to give people the ability to try things quickly, and view the results immediately.
这也是我来这里展示Siftables的原因—（掌声）
So here I'm — (Applause)
这是我用一个简单方程式做成的斐波那契数列。
This is a Fibonacci sequence that I'm making with a simple equation program.
Siftables还可以玩拼字游戏—一种Scrabble和Boggle混搭的拼字游戏。
Here we have a word game that's kind of like a mash-up between Scrabble and Boggle.
这种拼字游戏的玩法大致如下，你随意拿一块带有字母的Siftable,当你把几块带有字母的Siftables拼在一起组成单词时，Siftables会在字典里自动查找单词。
Basically, in every round you get a randomly assigned letter on each Siftable, and as you try to make words it checks against a dictionary.
大约30秒后Siftables会自动根据正确的单词拼写顺序改变原来显示的字母，组成正确的单词，你还可以尝试用其他的字母拼出新的单词。
Then, after about 30 seconds, it reshuffles, and you have a new set of letters and new possibilities to try.
现在，屏幕上显示的是一些孩子正在MediaLab里参与Siftables的试用体验，我把孩子们的体验过程拍了下来。
So these are some kids that came on a field trip to the Media Lab, and I managed to get them to try it out, and shoot a video.
孩子们非常喜欢Siftables。
They really loved it.
而且有趣的是在玩这个拼字游戏的时候我们并不需要向他们解释什么。
And, one of the interesting things about this kind of application is that you don't have to give people many instructions.
只要跟他们说这是个“拼字”游戏时，他们就知道该怎么做了。
All you have to say is, "Make words," and they know exactly what to do.
现在屏幕上显示的是另一些人在体验Siftables。
So here's another few people trying it out.
右下角这位是年龄最小的体验者。
That's our youngest beta tester, down there on the right.
他只是想把Siftables堆在一起。
Turns out, all he wanted to do was to stack the Siftables up.
在他看来，Siftables只是积木。
So to him, they were just blocks.
