Janina

Thank you for the Accessible Platform Architectures (APA) Working Group review [1] of the Vibration API PER specification [2].

The Devices and Sensors Working Group has agreed to defer consideration of this change until the next version of the Vibration API [3], for the reasons that Dom outlined in his previous response to your comment [4] (for example, no normative changes to the Proposed Edited Recommendation [5]).

Thank you for your feedback and please let us know of any other suggestions for the next version or for our other work (listed on the DAS page [6]).

Thanks

regards, Frederick

Frederick Hirsch
Chair, Devices and Sensors Working Group
