Colleagues: We are specifically requested for our review of Web Platform's Push API specification: https://www.w3.org/TR/push-api/ The following draft comment is offered preliminary to a formal Call for Consensus. This is our opportunity to clarify and perfect our comment, so please respond with any edits or suggestions. Draft Comment The Accessible Platform Architectures (APA) Working Group has reviewed the Push API specification at: https://www.w3.org/TR/push-api/ We find no issues with the API as presented, except that we believe additional feature support is required by emerging use cases. Missing Feature We require a mechanism whereby applications may temporarily block any push notifications or events. All such notifications or events should be queued until the application requesting temporary blocking has cleared the blocking request. We offer two use cases requiring such a feature. Use Case #1 A user engaged in a financial transaction at the point of making (or recieving) payment should not be interrupted by unrelated notifications and events. This is especially important for persons with disabilities relying on assistive technology, but is also relevant to all users of emerging web payments specifications. Use Case #2 Users need the ability to interact with certain web content without automated updates that might cause presented content to update in an adverse manner. This might be satisifed by allowing temporary pauses in push events, or by controlling a minimum time interval between push events. For more on this use case see the comment at: http://lists.w3.org/Archives/Public/public-apa/2017May/0026.html -- Janina Sajka, Phone: +1.443.300.2200 sip:janina@asterisk.rednote.net Email: janina@rednote.net Linux Foundation Fellow Executive Chair, Accessibility Workgroup: http://a11y.org The World Wide Web Consortium (W3C), Web Accessibility Initiative (WAI) Chair, Accessible Platform Architectures http://www.w3.org/wai/apa
