handMade hand track nulls

Script in progress: a Leap Motion recorder for After Effects

I’ve been building a tool for recording 3D motion tracks, camera moves and hand gestures direct to the After Effects timeline¬†with the Leap Motion.

There’s still a ways to go yet on development. I have to create¬†the UI and tweak the hand puppet rig (and, um, make the hand tracker work with right hands…), but I think this is going to be a useful addon for both literal hand-animation stuff like UI demos and pre-animating gestures for Character Animator puppets, as well as more subtle things like organic camera shake.

The Leap is quite precise in its data — you can even tell different people’s hand tracks apart.


Shaky camera move:

I’m thinking about calling it handMade. Good name?


Kumquat Cheering Squad: A silly Processing sketch for the LeapMotion.

I present my first-ever app for the LeapMotion: Kumquat Cheering Squad.

It’s a little Processing 1.5 sketch in which a bunch of friendly kumquats cheer you on. They will follow your fingertips or the point of a pencil or pen around the screen. It’s extremely silly, but it was a good first exercise with the Leap. And there’s a small Easter egg in there for you to find if you’re inclined to hunt for it. :-)

Here it is in action:

Why kumquats? I made this for Issue 4 of #24Mag as part of the Transmedia Chain — a recurring feature that’s essentially a game of Telephone between different media. The Issue 4 theme was “Audience” and the chain began with Steven‘s story about practicing a speech with only a single (tasty) kumquat looking on. I added more kumquats. And faces.

The Leap is a great device, but it has a ways to go. It’s going that way pretty quickly, but right now it still tends to get confused about which fingertip is which and how many there actually are, so I had to build something that didn’t rely on hand models or a single tracked point. If it loses track of you, KCS just adds another kumquat, no harm done.

I have somewhat grander plans for the future involving the Leap, but for now, I’m just excited to get something simple up and running.
