##About
This app is designed to allow users to experience conducting a simple orchestra using familiar motions. This app plays Mary had a Little Lamb in two voices: the bass and the treble. The user can control the volume of each voice as well as the overall tempo and rhythm with special, intuitive hand motions.
##Hardware Requirements
This app relies on the Leap Motion hardware to access the hand motions, so without this device the app will not run. Make sure you have that before starting the app.
##Installation Instructions
- Clone the repository.
- Run these commands from the directory of the app
git submodule initandgit submodule update. - Install the Leap SDK if you haven't already.
- Run `npm install -g http-server'. Since this app needs a server to run, we recommend using this node tool for that purpose. You can use any server tool, but this is what we tested the app on.
- Run 'http-server -p <port_number>' from the directory of the app with a port number that you like.
- Open 'localhost:<port_number>' to access the app!
##Controls
- Raise and lower each hand to control the volume of the parts (right-hand: bass, left-hard: treble).
- Do a circular motion with your hand to increase (clockwise) or decrease (cc-clockwise) the tempo.
- Fold your hand into a fist to hold that particular note and flatten your palm to release it.
##Notes
- Make sure that the back of the palm of your hand is on the Leap device. Otherwise the device might not register the hand.
- Due to performance limitations, it is recommended that only one hand is on the device at one time. You can use both hands, but not at the same time.
