These two experiments show that one sensor can be used to detect the angle between knuckle and the direction of gravity, two sensors can be used two detect angle between two different knuckles.
以上两个实验表明单个传感器可以检测单个指节与重力方向的夹角,用两个传感器可以检测两个指节间的夹角。

我说,“喂,重力方向是怎样的?”
假设这是铅垂。,想想重力方向是怎样的。
Think of this as being a plumb line to find... used to find the direction of gravity.
你会说,重力方向是个方向的“,就像真的有这个方向上的重力一样。”
And you say, "This is the direction of gravity" which is as real for you as it can be.
For most of us, gravity acts this way, defines a vertical direction very naturally and the blackboard is oriented this way, so very natural to call that x and call that y and line up our axes.
对我们多数人来说,重力作用下,很自然地确定了竖直方向,而我们的黑板又是这个指向的,所以很自然地定出 x 轴和 y 轴,并标出我们的坐标系
