The Vibration API allows us to tap into the vibration motor for our user's mobile devices and send a vibration to it.
This demo will require the use of actual hardware to test, but it is worth the setup if you have one to play with. On devices that don't support vibration, including the simulator, there will be no effect.
There are a couple of caveats to using the Vibration API that you should be aware of.
From a user experience standpoint, the use of vibration in your apps should be as a feedback mechanism to let your users know that some sort of interaction has occurred.
Additionally, extended use of the vibration motor on a user's phone will lead to larger stress on their device's battery performance.
It's very easy to abuse ...
