要可靠地检测打开按压动作，除了需要充分多的数据点以外，波动检测步骤不是必需的。

In addition to requiring substantially fewer data points for reliable detection of an open pinch, the wiggle-detection step is not necessary.

然后把所有测量值加起来，再除以数据点的数目，但这取决于你能有多仔细，原则上，有无限多个点要测量。

And then add all of these together and divide by the number of data points But, depending on how careful you are, actually, there are potentially infinitely many points to look at.

当然，你还是要找到最佳的，这里指对数据点，拟合度最高的抛物线。

And, of course, you are trying to find somehow the best. That would mean here fitting the best parabola for your data points.
