Usability Improvements

[UPstartDeveloper]

1. Add audio cues when you touch objects
2. Have a screen to “calibrate” your camera
3. Improve the resizing of the Three.js environment the window resizes

4. Making the bounding box and video display bigger. Assume user is ~24-30 inches from the camera.

5. Add buttons to let user toggle the video debugger on/off. Something similar to the following, in index.html:

<div>
  <button class="handsfree-show-when-not-debugging" onclick="handsfree.showDebugger()">
    Show Debugger
  </button>
  <button class="handsfree-show-when-debugging" onclick="handsfree.hideDebugger()">
    Hide Debugger
  </button>
</div>

Found on the Handsfree.js docs.
