Or you can just scroll on a scroll wheel.

或者只需滑动滚动轴。

We have the solid-state scroll wheel, right? Patent pending.

我们设计了这个固态的滚轮。正在申请专利。

And she said it was actually the scroll wheel on the mouse.

她说，其实就是鼠标上的滚轮。

Scroll wheels commonly use either optical rotary  encoders or magnetic rotary position sensors in order to measure rotational motion.

滚轮通常使用光学旋转编码器或磁性旋转位置传感器来测量旋转运动。

A haptic feedback scroll wheel ended up being the perfect solution.

触觉反馈滚轮最终成为完美的解决方案。

Well, in this episode we're going to explore the scroll wheel  in detail.

好吧，在本集中我们将详细探讨滚轮。

But how does the scroll wheel know which direction it's rotating?

但是滚轮如何知道它正在旋转的方向?

Because with the scroll wheel on a mouse, your hand never had to leave its resting position, you just scroll to see the next thing.

因为有了鼠标上的滚轮，你的手永远都不必离开起始位置，只需滚动手指就能看到下面的内容。

Let's move on to the other type of scroll wheel, the magnetic rotary position sensor.

让我们继续讨论另一种滚轮，即磁性旋转位置传感器。

So to fix this, we can pass in another property called scroll wheel and set that to false.

因此，为了解决这个问题，我们可以传入另一个名为滚轮的属性并将其设置为 false。

Now what's really unique here is on the right cup you've got a volume scroll wheel, so you can raise and lower your volume very easily.

真正独特的地方是在右边的盖这里是一个卷盘，用于调节音量。

Here we have the scroll wheel assembly below which you'll most likely find a push button.

这里我们有滚轮组件，在它下面你很可能会发现一个按钮。

Most scroll wheels have some type of mechanism  to create the clicking-like motion and sound as the scroll wheel rotates.

大多数滚轮都具有某种类型的机制，以便在滚轮旋转时产生类似咔嗒声的动作和声音。

That's pretty much it for scroll wheels.

对于滚轮来说，基本上就是这样了。

Additionally,   there are different methods for registering a scroll wheel push and for creating different  aesthetics when you rotate the mouse.

此外，还有不同的方法来注册滚轮按压并在旋转鼠标时创建不同的美感。

For example, this scroll wheel uses an electro-permanent  magnet and teeth that conduct magnetic fields resulting in the wheel stepping from tooth to  tooth.

例如，该滚轮使用电永磁体和齿来传导磁场，导致滚轮从一个齿到另一个齿。

The information is not speed, however, but  rather, the angular distance measured in degrees and the direction the scroll wheel has travelled  every hundredth to a thousandth of a second.

然而， 信息不是速度，而是以度为单位测量的角距离和滚轮每百分之一到千分之一秒行进的方向。

When you  push down on the scroll wheel it triggers the button, and when you release it, the plastic, or  sometimes a spring, pushes the assembly back up.

当您向下按下滚轮时， 它会触发按钮，当您松开它时，塑料或有时是弹簧会将组件向上推。

For example, if you scroll the wheel down, the pulse train from the two adjacent sensors will look like this, whereas when you scroll the  wheel up, it will look like this.

例如， 如果向下滚动轮子，来自两个相邻传感器的脉冲序列将如下所示，而当您向上滚动轮子时，它将如下所示。

If you spin  the wheel quickly, the plastic will continue to move up and down, and slow the wheel faster than  if the follower were not pressing up against the plastic and the scroll wheel was spinning freely.

如果您快速旋转轮子，塑料将继续上下移动，并且比从动件没有压在塑料上并且滚轮自由旋转时更快地减慢轮子的速度。
