• User Need 2: A blind user of both screen reader and braille output devices may need to manage audio and text output differently e.g. once they have accepted the call a user may wish to route notifications to a separate braille device while continuing the call on bluetooth headphones.
• REQ 2a: Provide or support a range of browser level audio output and routing options.
• REQ 2b: Allow controlled routing of alerts and other browser output to a braille device or other hardware.
• User Need 3: A deaf user needs to move parts of a live teleconference session (as separate streams) to one or more devices for greater control.
