# Method: handsfree.start()


Loads tracker dependencies, starts the webcam, and starts the main loop. Calls an optional callback just before the first frame.

The document body receives .handsfree-loading before the models are actually loaded, giving you a chance to style custom loaders. Then a handsfree-loading event is triggered on the document immediately after, allowing you to run any final logic before the models are actually loaded.

# Parameters

callback: function
(optional) A function to call after dependencies are loaded but just before the first frame

# Example

const handsfree = new Handsfree({weboji: true})
handsfree.start(() => {
  console.log('weboji started!')
