Capture hand motion with Leap Motion

[tianxiaotian]

I am doing a project about how to capture hand motion accurately. And now I ｊｕｓｔ ｃａｐｔｕｒｅ ｔｈｅ ｔｉｐｐｏｓｉｔｉｏｎ ａｂｏｕｔ ｆｉｖｅ ｆｉｎｇｅｒｓ， ｂｕｔ Ｉ am not sure if the position was right.
The tipposition in driver 2.3.1 is better than which in 3.2?
Ｉｎ ａｄｄｉｔｉｏｎ， I ｄｏｎ｀ｔ ｋｎｏｗ ｔｈｅ ｆｒａｍｅ ｐｅｒ ｓｅｃｏｎｄ ｅｘａｃｔｌｙ ａｎｄ ｈｏｗ ｔｏ ｃｈａｎｇｅ ｔｈｅ ｆｐｓ？

Framerate is determined by the capabilities of the machine running the controller, not the application. See here: https://developer.leapmotion.com/documentation/javascript/api/Leap.Frame.html?proglang=javascript#Frame.currentFrameRate

Tip position for the controller in the upward-facing orientation is more reliable in 2.3.1.
