Is it possible for a web app to gather an iPhone's accelerometer data? If so, how?

Question

Is it possible for a web app to gather an iPhone's accelerometer data? If so, how? I would think they might have in the Safari Web browser an API with such functionality.

If it is possible could someone send me a link to pages with specific coding information.

Found this snippet from here with a bit of Googling.

window.ondevicemotion = function(event) {
  ax = event.accelerationIncludingGravity.x
  ay = event.accelerationIncludingGravity.y
  az = event.accelerationIncludingGravity.z
  rotation = event.rotationRate;
  if (rotation != null) {
    arAlpha = Math.round(rotation.alpha);
    arBeta = Math.round(rotation.beta);
    arGamma = Math.round(rotation.gamma);
  }
}

What language is that? Javascript? – OOProg Jun 19 '11 at 16:15
Yeah, I'm not aware of Safari supporting any other scripting language. – Bemmu Jun 20 '11 at 15:10
