LEAP Motion variables

so i mounted the LEAP motion on a clamp to put it sideways and discovered that it works okay, but there's a reason why it's better the way it's meant - because you don't get false reads from things like your elbow or your body depending on how far away you are from the device itself.

still, once i was able to mess with it a little bit and make some adjustments, i got the sideways thing to work okay, we'll see what happens as the piece develops. In my head, i now want the LEAP to do four things:

  • Simply trigger a sound when a hand enters the motion field (already programmed)
  • Trigger a sound when a hand enters the motion field, then pause-but-still-play-the-sound when the performer's hand closes into a fist and then continue when the hand opens up again
  • Trigger a sound when a hand enters the motion field, pause-but-still-play-the-sound when the performer's hand closes into a fist, then stay frozen and allow the performer to place it anywhere within the octophonic space using the motion field as a map.

That visual mechanism for the last thing i'm unsure about. I could make it so that opening the fist in those specific instances does that, but i want something to be visually different about that circumstance (even though the triggers themselves won't be free for all, i'm not going to leave that to chance based on some of the hand/fist tracking issues). Maybe i could do a single finger visually and put that on the performer to know when to put the single finger out for controlling that sound.

i'm not sure if the piece really needs anything else for the LEAP motion to do. If i add a bass pitch to the sound halfway through that could complicate things, but i'm sure i could figure it out. Right now i just want to program the other two things first and start to actually put the first part of the piece together along with figuring out the UI and the cueing mechanisms and the cuelist.
