Reading Systems Accessibility Support Roundup

Note: this article was last updated following retesting in August 2019.

Introduction

With the advent of digital publishing and eBooks, the opportunity now exists for people with reading disabilities to enjoy an unprecedented number of books and other publications. Publishers are increasingly adopting standards, techniques, and tools to ensure that their titles are accessible.

A digital book is accessed using a reading app, which is used to open, read and navigate the content. It is important that individuals and organizations can choose reading systems that offer the accessibility features they need. The required features will vary between individuals and might include support for a screen reader, the ability to change the visual presentation of the contents, a read-aloud feature, the capability to enlarge images and so on.

Here we present a roundup of popular reading apps that can be used with the world’s most accessible publishing format, EPUB. The summary reviews are based on detailed accessibility evaluations conducted using a protocol developed by and with people with print disabilities. More information on this structured protocol is given at the end of the article.

The results of the evaluations were accurate at the time of publication but may not reflect all personal experiences which can be affected by the version of the reading systems, assistive technologies or the publication being read. The apps change constantly, and developers improve the features based on the feedback from our tests. You can always read the latest reviews at http://epubtest.org/

Reading Apps Roundup

Amazon Kindle icon

Amazon Kindle

Books from the world’s largest eBook store are read using the Kindle app. The app is available on most computer and smartphone platforms, including Amazon’s own Fire Tablets. The Kindle app has been evaluated by our testers on iOS, Android, Windows and Fire tablets.

Our evaluators liked: The voices on the Fire tablets are high quality and natural sounding. Your own documents can be easily added to the app by sending them by email. Support for visual adjustments is good on all platforms. There are useful features in the app such as “word wise” that explains the more challenging words in the book. On some books, it is possible to combine the eBook and Audible audiobook for a synchronized reading experience (purchases necessary). Titles in the Kindle eBook store indicate whether they are screen reader supported or not.

Be aware: Heading navigation using Voiceover (iOS) or Talkback (Android) is not supported. Table navigation is poor. Image descriptions are not announced using Voiceover or Talkback. Print page navigation is not supported. There is no built-in read-aloud feature in the app on Android, and the Speak Screen feature on iOS does not provide visual emphasis of the words being spoken. Your own EPUB titles cannot easily be loaded into the app.

Adobe Digital Editions icon

Digital Editions

Adobe’s reading software is widely used for reading pdf files, but it reads EPUB as well. It is available on most phone and computers platforms. It is often recommended by public and academic libraries because the titles loaned from their systems use the Adobe copy protection. It is the only option for titles downloaded from many library systems, and sadly it is hard to recommend due to poor stability and lack of fundamental accessibility features.

Our evaluators liked: it is convenient to have pdf and EPUB reading in the same app.

Be aware: Our evaluators found Digital Editions on Windows to be unstable and it struggled with larger books. Reliability issues are also reported on iOS and Android. Navigating the table of contents with a screen reader was unsatisfactory. There is no function to change the screen colors or font, and no built-in read-aloud feature, limiting the appeal to people with learning differences such as dyslexia.

Dolphin EasyReader App icon

Dolphin EasyReader

This specialist reading app for Windows, Android and iOS is designed to provide many features required for people with reading disabilities. Several file formats in addition to EPUB are supported.

Our evaluators liked: Many useful features are provided for people with print disabilities, including screen reader support, several options for visual adjustments and read aloud. The app can be used to open titles on your device, and it also connects directly to the special library services in many countries (you need an account). The mispronunciation of words by the read-aloud feature can be corrected. An enhanced version of the app is built into the BrailleNote Touch device from Humanware.

Be aware: Continuously reading with a screen reader stops after a few pages due to the way the app displays the title. On Android and Windows hyperlinks are not followed when using a screen reader.

Microsoft Edge icon

Edge

The web browser built into Windows 10 is an eBook reader too! It is the default EPUB reading app in Windows 10, so using it is as simple as opening an un-protected EPUB eBook.

Our evaluators liked:  books can be opened straight from a website or Windows Explorer. The implementation of read-aloud with visual highlighting was praised. The visual adjustments include more than 20 background colors, the ability to increase the letter spacing, and different parts of speech can be shown in different colors.

Be aware: The EPUB reader in Edge will be replaced by other solutions in a forthcoming Windows update (possibly in Q1 of 2020).

Apple iBooks icon

Apple Books

Apple’s bookstore uses the Apple Books app (which used to be called iBooks). If you have an iPhone, iPad or Mac, the app will already be installed.

Our evaluators liked: the visual display of the title can be adjusted to suit the reader’s needs. Some images enlarge to full screen when selected, useful on a smaller screen and to people with low vision.

Be aware: Apple Books is not available on Android or Windows.

 

Kurzweil 3000 logo

 

Kurzweil 3000

The web license version of Kurzweil 3000 offers a powerful study aid for learners with reading differences such as dyslexia. Content, including EPUB 3 titles, can be uploaded to the ‘Universal Library’ from the local computer, Google Drive or Bookshare. A Chrome and Firefox extension can also be used to add read-aloud features to the browser, which can work with EPUBs read on some library platforms.

Our evaluators liked: the familiar features of Kurzweil are available in EPUB files, including flexible read aloud modes with high-quality voices, dictionary, picture dictionary, thesaurus, translations and study highlighters. Several different background colors are offered. The table of contents is available through the ‘bookmarks’ menu.

Be aware: if page navigation is provided by the publisher, this is not supported. The font cannot be personalized. The text does not reflow like regular EPUB readers. Some navigational features such as hyperlinks are lost. Kurzweil 3000 is a paid-for subscription service. A demo version is available.

Google Play Books icon

Play Books

The eBooks obtained from Google’s book store app are read in their Play Books app. The app is usually already installed on Android phones and tablets and can be downloaded for iOS devices from the Apple app store. The books can also be read using Play Books via a web browser on Windows, Mac, and Chromebook computers. Your own EPUB titles can be uploaded to your library through the app or using the Play Books website.

Our evaluators liked: eBooks and audiobooks can be read in the same app. The simple to use built-in dictionary (just highlight a word) may be especially useful for people with specific learning disabilities.

Be aware: Continuous reading with Talkback on Android is not supported, so reading is limited to screen by screen. There is no read-aloud feature on iOS. On Android, the read-aloud feature could do a better job of pausing between heading and paragraphs, and it is difficult to control where it starts from.

RedShelf Logo

RedShelf

This cloud-based eReader is accessed through your preferred browser on your computer, tablet or phone. It can be used to read textbooks and novels and consumer titles purchased from the RedShelf store.

Our evaluators liked: No software installation is needed, just point your web browser at the RedShelf site. Word definitions are one step away, and it is easy to add highlights and create flashcards which are instantly stored in the cloud.

Be aware: It isn’t possible to change the font. You need to use a browser extension to change the background color. You cannot sideload your own EPUB files.

Simply Reading App icon

Simply Reading

This Android app can be used by anyone, but special attention has been paid to creating an easy to learn interface for a new screen reader user. It can be used to directly connect to Bookshare, Sugamya Pustakalaya, Gutenberg and Dropbox, or it can be used to open EPUB files on your device.

Our evaluators liked: support for Braille displays (including the Orbit Reader) using BrailleBack. Functions can be performed with easy gestures as an alternative to navigating the menus.

Be aware: internal hyperlinks are not consistently supported. There is no read-aloud feature built into the app for people who do not use a screen reader.

Vital Source Bookshelf App icon

Vital Source Bookshelf

VitalSource is a platform for textbooks and other educational titles. The reading apps are available for Windows, Mac, iOS, Android and via a browser. Your own unprotected EPUB files can also be side-loaded into the app.

Our evaluators liked: a suite of stable reading apps across many platforms with good support for screen reader and refreshable braille users. Notes and highlights are synchronized across devices for books from the VitalSource Store. The Bookshelf reader now offers a Read Aloud feature, and the ability to change fonts, colors, margins, and line-height.

Be aware: On Windows, version 8 is the current release, but screen reader users should use version 7 due to accessibility issues with the newer version.

Voice Dream App icon

Voice Dream Reader

This specialist reading app for iOS and Android is designed to provide many features enjoyed by people with reading disabilities. Several file formats are supported, in addition to EPUB.

Our evaluators liked: Many useful features are provided for people with print disabilities, including several options for visual adjustments and read aloud, and screen reader support on iOS.

Be aware:  The iOS version is more mature than the Android app. Some features are missing that would be important to readers of educational content, such as images, tables, and hyperlinks. Compatibility with Talkback on Android is poor. This is a paid-for app on iOS and Android.

 

How the accessibility features were evaluated

Apps are evaluated using the protocol published at epubtest.org. This accessibility testing protocol has been developed in collaboration with people with reading disabilities, accessibility experts, and reading system developers. It is an open effort, with the test process described on the website, and more than 70 volunteer testers with different reading disabilities collaborate in the testing effort.

The basic assumption of the approach is that apps should support reading by eyes, ears or fingers. It should be possible for users to read the content by:

  • adjusting the display such as adjusting font size and color combination,
  • reading the text with a screen reader or integrated read-aloud feature, and
  • reading the text on a refreshable braille display.

The apps are evaluated using different combinations, with and without assistive technology. All reading apps are tested using the same standardized test titles, to ensure consistency. The test files are available from http://www.epubtest.org/testbooks

The evaluation protocol is free to use, and anyone can evaluate a reading system. If you are an app developer you can ask us to look at your app, and we will report the results back to you.

The latest detailed results for the apps in this round up, and many more, are available at http://www.epubtest.org/results
