Re: Vibration spec and Cordova integration update

Frederick~

This change would definitely address the list [0] use case.  I have no 
additional feedback on that change.  Looks great!

What are your thoughts on the Windows phone issue when the value is 
greater than 5000?

Thanks for sharing this update to the list - this helps reaching all WG 
participants.

I’ve created a new Last Call issue for the Vibration Specification to 
track this comment:  LC-2945  , 
https://www.w3.org/2006/02/lc-comments-tracker/43696/WD-vibration-20140619/2945



I propose we resolve the issue as follows:

Change section 4 (Vibration Interface) Step 9.2  [1] 

from  "If pattern is an empty list, or if the device is unable to vibrate, 
then return true and terminate these steps.“

to

"If pattern is an empty list, a list containing a single vibration entity 
with max duration of 0, or if the device is unable to vibrate, then return 
true and terminate these steps.“

I would categorize this change as editorial, since having a max duration 
of 0 could be interpreted as the ‘device is unable to vibrate”, however I 
think a clarification could be helpful and be incorporated as part of the 
process of creating a CR publication draft.

Thoughts?

Cordova we will document this shortcoming.  If someone has a connection 
with the windows team it would be interesting to get their take on this. 
They might not be aware.  I would expect it to at least vibrate for 5000 
and then not acknowledge anything larger if that is their intent.

about what should cancel a vibrate. Which is either navigator.vibrate(0) 
or navigator.vibrate([]). So what should navigator.vibrate([0]) do?  In 
Cordova land we also treat navigator.vibrate([0]) as a cancellation.
