 Welcome to an accessibility tour of Libby, version 1.81 on iOS. This video was created with support from the Government of Canada's Social Development Partnerships Program, Disability Component. The opinions and interpretations in this video are those of the creator, and do not necessarily reflect those of the Government of Canada. It was produced with sighted assistance. The Libby app strives to provide access to audio books and e-books from local libraries, but lacks accessibility in crucial areas. Before we dive into some suggested improvements, let's take a quick look at why they're important. To get the most out of a smartphone, those who are blind turn on voice feedback. Then they can swipe quickly to different controls on the screen, and hear any text that appears. Press reader, Libby. Libby, welcome to open the active title, button. In order to navigate a screen effectively, it is important that all buttons be labeled. Controls need to be swipeable, and screens must be clear of hidden text. We will now explore four accessibility challenges with Libby, version 1.8.1 on iOS. We will explore focus issues with pop-up menus, show a number of unlabeled buttons and the difficulties this results in, demonstrate voice-over speaking invisible text, and highlight the challenges faced when attempting to actually read books. When a menu or feature is activated, the previous screen is slid over to form an inactive background. This is a common practice throughout the app, but presents a major challenge for voice-over users. Instead of being positioned on the new controls, the user is left stranded on the previous screen. A prime example of this is the menu button. When activated, it expands with options such as add a library and learn Libby. However, instead of being able to swipe to these options, we can only navigate the original screen. The only way to access the menu field is to tap on the top right of the screen. Then swipe through its controls. This is problematic because blind users will not know where the menu is or even that they have to tap it. Furthermore, when swiping through a screen when a pop-up is displayed, its options mingle with the existing content. This makes it almost impossible to tell which controls are part of the pop-up. Unfortunately, back-field interference is another serious concern. Occasionally, voice-over will mistakenly read text and controls that are no longer visible. We refer to this phenomenon as back-field interference. It occurs when new controls are painted over existing ones without first clearing the screen of its old content. Here, we'll demonstrate one area where back-field interference is prevalent. It's important to note, though, that this issue does crop up randomly and persistently throughout the entire app. When we no longer need the menu, we click hide. However, the menu controls are still exposed to voice-over. Being prompted to interact with controls that do not exist represents a level of frustration rarely experienced elsewhere. Please ensure that each screen of your user interface is free and clear of old controls and text. The audio player is not usable due to many compounding accessibility issues. When we press the open button from the bookshelf, the screen that comes up is littered with countless controls. Their labels make no sense to a voice-over user, and most controls don't seem to correspond to actual functions. In addition to being unlabeled, many important controls, such as the play button, are skipped when using voice-over swipe gesture. These issues represent an insurmountable barrier to access for non-visual readers. Unless important buttons are labeled, meaningless controls are removed, the screen can be logically navigated with the swipe gesture, and icons are enlarged so they can be easily found by touch. Blind readers will be unable to listen to audiobooks with Libby. Sadly, reading is not an option. Blind readers will be unable to listen to audiobooks with Libby. Sadly, reading e-books is equally difficult. No buttons are labeled, and continued use of the feature introduces serious backfield interference. The multi-step process of accessing the list of chapters is far too complex, and unlabeled buttons combine with focus challenges to render it unusable. If a user does manage to select a new chapter, a voice-over usually reads the wrong page. Finally, it is not possible to scroll the book using voice-over's three finger gesture. Voice-over doesn't even recognize the button at the far right of the screen, so voice-over users will have no idea how to turn pages. It takes a lot of time and hard work to produce an app of this caliber, and we appreciate your willingness to explore increasing its accessibility. The modifications requested here can be made without impacting the visual look and feel of the interface, but will be greatly appreciated by those reading your content with speech.
