附件里是应用的2个截图。
第一个是两次driver swing测算出得的club speed
这里是练习动作,没球。在102-105
第2个是应用的主界面, real-time data capture and drawing
下午还去了趟golf smith, 用里面的一套laser detector, 和这个接近

测得我的club speed 从92-97 mph
而当时测得的动作 基本上低5 - 8 mph, 也就是说低8ph (< 10% differ)
从本质上讲,我更相信我的数据,因为我知道我用力气不用力气,iphone很容易显示区
别 (10mph dif),而在simulator, 区别不大(3-5 mph)。
图3
即使以simulator做为参考,假设simualtor是准的,我的sensor也是consistent的变化。
结论: 我觉得还能用。

I have not published it yet.
Still working on collecting more data and make it more useful.
Like promote instant feedback to the user if the something was off.

I don't think there is any useful existing yet.
The point is how you can measure?
I know a guys selling his app $9.99 by capturing the contact moment of swing
. -- this needs high speed camera, and some math involved.
My approach is , actually, measuring how fast you can flip your wrist. Since
we are talking about "your hands are actually mimic the club face, with the
help of your arm." So my approach is making some sense.
Since we are flatting our left fore-arm with the back of our left hand (
given left-handed), which means we barely bent our left wrist during the
swing, so measuring the rotation speed of left wrist is *close* to measuring
the rotation of left hand.
