Rich Schwerdtfeger CTO Accessibility Software Group From: Pete Brunet <[email protected]> To: IAccessible2 mailing list <[email protected]> Date: 07/13/2011 12:49 PM Subject: Re: [Accessibility-ia2] Braille devices and live regions Sent by: [email protected] Does anyone have any input on my question? Rephrasing... While listening to the audio track the hands would stay on the Braille device reading the text descriptions as they are received and after consumption of each one a Braille key would be pressed to request a resumption of video playback. That Braille key could be the same one used in the case of a rude non-video live region alert (if rude still exists) to move back to the interrupted POR.
