And thus begins our exciting "leap" into the SDK, starting with the basics of reading finger information and tracking where the user is pointing. We'll continue filling in the details of the rest of the functionality in the SDK along with some more fun examples in the rest of the book. While we have only just scratched the surface of what can be done with Leap, you should already be starting to get ideas of how to engage with users using hand motion input. Try out some of the example applications that come with the SDK for inspiration to get a feel for what it can do.
You should now have a working application written in C++ with a frame callback that has access to all of the hand tracking data captured by the controller. Next up, we'll look at making an application interface that is as responsive as possible.
