Thank you for your interest, however, from the Introduction [1]:
>> the API is not meant to be used as a generic notification mechanism.
>> Use cases requiring notifying the user may be met by another specification, Web Notifications [notifications] [2].

Further, you should note that if you write your application using the Vibration API, then it will probably not vibrate if the application isn't focused [3]: (step 6 of processing vibration patterns) If the hidden attribute [PAGE-VISIBILITY] is set to true, then return false and terminate these steps.
