      Patron searches for an audiobook (see alternate flow for borrowing from details page):

      Audio books display in search results with:

      • 'Get' button if available for download
      • 'Reserve' button if not available for immediate download

      Screenreader should:

      • reads "get"
      • (nice to have) reads "get" plus the title of book when there is focus on the button 

      Patron navigates to the details page:

        • 'Get' button if available for download
        • 'Reserve' button if not available for immediate download
        • Message displays in banner: "This book is available to borrow."

        • Number of days left displays
          • with focus still on the button, number of days left is announced (just on the immediate state change)

      (From a User perspective flow should be identical to borrowing ebooks.)

       

      For a screen reader user, the focus should stay on the same part of the page once they hit "get" or "reserve" button. After they hit either of those buttons, the focus stays on the loading area and the state is communicated, ex. "Requesting". Once the book is reserved or checked out and the buttons change, the focus should stay on the new "Read" button. It should also be announced the number of days that the user has until the book is returned.

       


      Patron clicks 'Get' from the details page:

      • 'Listen' button replaces 'Get'
        • number of days left displays
        • Accessibility: focus stays on the button and new button state is announced
        • with focus still on the button, number of days left is announced (just on the immediate state change)
      • 'Return' button displays
      • message in banner: "Your audiobook is ready!"

      For screenreaders:

      The focus should stay on the area of the selected book. It should announce a loading message, like "Requesting". Then when the request has been put through, the updated text should be announced, which will be "Title, author, buttons." The buttons will either be "Remove" if the book has been reserved or "Listen" button and "Return" button if the book has been checked out.

      There are issues in focus movement when user actives download.

      Download progress needs to be announced to users of screenreaders.

      Screenreader users need to be notified when Download is complete.

      Text display needs to include format.

      All behavior described in the main flow should work the same except that the player should not begin playing again until user taps "Play" button.

      Functionality needs to work for screenreader with feedback on where user is. If moving the scrubber causes audiobook to read very quickly at corresponding place in audio, that may present conflict with screenreader so need to discuss.

      when patron gets a phone call, or starts using another app, behavior should be as it is for any app, but need to describe it here.
      Question: does it pause for all apps or does it let you listen while you are doing other things. How are we controlling this?

      When audio is playing and user navigates away from the player to another page within the app, a mini player can be shown so that user can continue listening while browsing another content. (UI TBD)

      How is this announced to screen readers, all apiece? Ie "Forward 24 minutes 12 seconds"

      The indication of the current chapter needs to be communicated to screen readers.

      The downloading icons/whatever that grey circle is both need to have alts for screenreaders.

      Question: should the chapter begin playing as soon as it is selected or does the listener have to click the "play" button?

         Audio should not play automatically.

      Is the cover image being used to convey the author info? This should be conveyed as alt but presents an issue for patrons with low vision and/or color blindness.

      The placeholder mockup is depending on context of the list items and color to communicate which menu this is. I would prefer if the sleep icon was not shown, to reduce possible confusion. What is this going to be like for a screen reader? What's the order of the page?

      Out of scope for initial release: Would be nice to be able to turn off the timer if user changes their mind (or can't go to sleep and wants to listen longer)

      Out of scope for initial release: Would be nice to display the sleep timer on the UI when it is active.

        This basically turns the phone off, which most people don't do overnight.
        Confirm with Greg or Winnie that this is how the feature should work.

      There are a couple accessibility threads we need to confirm for this.

      Open Questions

       QuestionRelated toAsked byResponses
      1If the user opens an audio book player, opens the table of contents, starts one or more parts downloading, closes the table of contents, closes the player... Are the parts still downloading? If the parts are downloading, this implies that there are one or more instances of the `AudioBookType` that is living somewhere globally in the app, independently of any particular activity, and that parts of the app can get references to them to control them. Mark

      Kim: Looking at how Overdrive/Libby does this. If I stop playing the book before it is downloaded I get a "download paused," message. Seems like we should do something similar. Here is a screenshot of how Libby displays a paused download. Will ask Jack to weigh in on this.

      Mark: It looks as though that screenshot is from something analogous to our "book detail view" in the SimplyE catalog section. If so, then that definitely does imply that `AudioBookType` instances exist outside of the player activity; if they didn't, then there'd be no way to display the current download status in the catalog.

      2If book parts are allowed to continue downloading in the background, how is error reporting actually implemented? Do we just pop up a dialog box anywhere the user happens to be, whenever a book part publishes an error event? That's awkward to implement on Android. Mark 
      3How do we implement tabs in the catalog? Last time i looked, the catalog was activity based instead of fragment based... How does this work with tabs?Use Case 1a & 1bMark 
      4The requirements talk about being able to "close" the player view and still have the book playing, possibly with a small player view that appears in the catalog. How can this be achieved? If the player instance (not the view) is instantiated in an activity (and the activity "owns" the player), then we lose the reference to that player instance when the activity is closed. References to players are not serializable and can't be passed between activities. Mark 
      5When the user borrows an audio book, it's necessary to fetch the book manifest so that an `AudioBookType` instance can be instantiated from it. When exactly is this manifest fetched? Manifests appear to be able to expire (Findaway books in particular have session IDs), so fetching them eagerly and saving them to disk might not be a good idea. Are manifests saved on disk? Mark 


      Out of Scope Items

      1. Supporting the web app is out of scope for the October release, but for a later release: need to implement an alternate flow for the web app. so that it displays a message to go to SimplyE to listen. This would be the same downloading most ebooks. Need a design, including accessibility requirements.
      2. After launching 3.0, test whether users expect to see last tab selected when they view catalog.
