These little movements are called saccades.

这些小动作叫做扫视。

So eyes move in terms of saccades.

所以眼睛的移动就像眼跳一样。

We're sort of kind of saccading back and forth.

我们有点像来回扫视。

Since the fovea is pretty small, your eyes read text by making quick jerky movements called saccades.

由于中央窝很小，你的眼睛就会通过快速跳动的动作来阅读文本，这个动作被称为扫视。

Saccade back and forth between the two faces, right?

在两张脸之间来回扫视，对吗？

Human eyes tend to move in discrete jumps, called saccades.

人眼倾向于以不连续的跳跃方式移动， 称为扫视。

The team created a computer simulation based on the distribution of saccade lengths.

该团队根据眼跳长度的分布创建了计算机模拟。

I know that if saccade down for a half a second, they will see it.

我知道, 只要蹲下半秒, 他们就会看到。

Scientists have found that tiny eye movements called saccades occur when you look at this image.

科学家发现，当您观看该图像时，会发生称为扫视的微小眼球运动。

The artist actually takes a more global approach to looking so they make bigger saccades, bigger eye movements, and shorter fixations on the image.

艺术家实际上采用了一种更全面的方法来观察所以他们扫视的范围更大，目光移动的幅度更大，注视映像的时间更短。

And that means that you're not wasting any eye time in doing saccades back and forth between bits of the same line.

这意味着你没有让眼睛浪费时间在同一条线的片段之间来回扫视。

Both saccades and fixations take time to do, which essentially sets a speed limit on how fast you can visually process text.

扫视和定影都需要时间，这实际上就是对视觉处理文本的速度设置了一个限制。

That time is split between small regressions due to saccades that went too far the first time, and larger ones that are needed for comprehension.

这个时间被分成小回归阅读和大回归阅读，前者是由于第一次扫视时跳得太远，后者是为了理解而需要。

She investigates how artists see the objects they are drawing by measuring saccades the rapid movements our eyes make as they jump from one thing to another.

她通过测量扫视来研究艺术家如何看待自己所画的物体，扫视是指我们的目光从一个物体跳到另一个物体时所做的快速运动。

The idea here is to eliminate the need for saccades, but it breaks down because it doesn't allow the brain to intelligently skip function words or to do any regressions.

它是想消除扫视的需要，但这样它就会崩溃，因为它不允许大脑智能地跳过功能词或做任何回归阅读。

Well because, unnoticed by you or me, our eyes are always moving in these microscopic little flutters called saccades to make sure that the stimulation on our visual receptors is always changing.

好吧，因为在你或我没有注意到的情况下，我们的眼睛总是在这些称为扫视的微观小颤动中移动， 以确保对我们视觉感受器的刺激总是在变化。

So here's the crazy thing about saccades: Your eyes are jumping around about three times a second, and in between that they're making these little micro saccades, they're making little tiny jitters.

扫视的疯狂之处在于：你的眼睛大约每秒跳动三次，在这三次跳动之间，它们会产生微小的扫视，它们会产生微小的紧张。
