Michigan Assistive Technology Webinar: Screen Readers: Making Your Computer Talk! Presented by M. Cathy McAdam
Objectives To understand the use of screen readers for Windows and Apple computer systems including the iPad. To understand features valuable to specific users depending on disability or literacy needs To explore device demonstrations available for consumers To introduce accessibility concerns
What is a Screen Reader? • Screen readers are software programs that allow users to read the text that is displayed on the computer screen with a speech synthesizer. • A screen reader is the interface between the computer’s operating system, its applications, and the user. • The user sends commands by pressing different combinations of keys on the computer keyboard to instruct the speech synthesizer what to say and to speak automatically when changes occur on the computer screen. • -- American Foundation for the Blind
Screen Reader Commands A command can instruct the synthesizer to read or spell a word, read a line or full screen of text, find a string of text on the screen, announce the location of the computer’s cursor or focused item.
Advanced Functions Allows users to perform more advanced functions, such as locating text displayed in a certain color, reading pre-designated parts of the screen on demand, reading highlighted text, and identifying the active choice in a menu. May combine magnification options.
Who uses Screenreaders? People who are blind or visually impaired, People who have learning disabilities, and people with literacy issues.
Who Pays for Screenreaders? Some are free, and open source, Others can cost up to $1000+. Can be part of an education/employment plan Can be covered by state rehab programs Not medical insurance Service clubs Texas program for low vision/blind
Demonstration Webaim Simulation: Download software to view simulation Surfing the Web with a Screen Reader: AccessIT demonstration of a screen reader
Can Screen readers read graphics? A screen reader cannot read unlabeled graphics, PDF file scanned as photos, pictures or links not labeled correctly instead you hear a string of numbers, or “image map link” or “graphic” with no clarification
Filling in Forms? <label for="firstname">Enter your first name:</label> A screen reader can be used to fill in forms if they are created correctly. In some cases the fields are not labeled so there is no way to know if you should put in your name title or address.
Banking or Shopping Online Can you bank or shop online with a screen reader? Yes, but depends on the site the National Federation for the Blind sued Target for not being accessible/useable. Some compare it to not being able to get into an un-ramped building. Using a screen reader only gets you to the door.
Good Design For all screen readers… programs, web sites or documents are only as good as the interface between the software and the operating system, application, or program… a very complex process. MSU offers a well done tool kit.
Features to consider Magnification options LD/literacy tool Key board skills Touch screen use Verbosity Voice options Braille compatibility
Which one works best • “Often I'm asked which screen reading program is best for users who are blind or have low vision. My response is always the same: It depends. • It depends on what computer tasks the person is trying to accomplish, and the type of environment in which he or she is working.” • – Ike Presley, American Foundation for the Blind Project Manager, Professional Development • And it also depends on print disabilities beyond vision.
Additional Considerations Advanced use at work and/or school Spread sheets Editing or publishing documents Using specialized programs “Scripting” options
Apple Voice over, built into all their products. Can now use in conjunction with magnification option Siri allows voice activation for browsing/email Touch screen
Using a Keyboard with Apple Mac has accessible key board options iPad can be supplemented with Bluetooth keyboards for print or Braille
Microsoft Narrator works best with note pad, trouble shooting Accessibility features for keyboard magnification and mouse use Speech recognition not functional with screen reader Collaborated with NVDA a free screen reader
Keyboarding Check out the website All Hot Keys: Your source of hotkeys and shortcuts for software.for operating systems, browsers and more.
Web Browser Extensions ChromeVox is available as an extension for Google Chrome FireVox is an open source talking browser extension for the Firefox web browser. Switching between browsers can enhance accessibility for advanced users. Can be ever changing and difficult to keep up.
Plus Magnification • Not fully functional for totally blind user • Not just magnification, examples of features: • Full range of color enhancements • Options for viewing the mouse and cursor • Easy interface with smooth scrolling • Examples of software: • Magic from Freedom Scientific • ZoomText Magnifier/Reader from AI Square
Other Magnification Improved built in magnification with later versions of Windows and Mac for low vision users. Legally blind user may need more. Only way to know is to try, visual issues vary greatly. Can help with learning tracking issues as well. System Access to Go (when user is online) Free low cost shareware is available for older computers
For Literacy/LD • Use visual interfaces to strengthen and support reading skills • Examples: • WYNN, from Freedom Scientific uses color coding, tracking, voice feed back • Word Q/SpeakQ word prediction, ability to read highlighted text, tracking while reading
For people who are Blind • Very verbose, detailed information about controls menus necessary for orientation and operation of the computer • Examples: • JAWS Freedom Scientific • Window Eyes GW Micro • Dolphin (British Company)
Free Screen Readers - Windows Non visual Desktop -NVDA Thunder System Access to Go (when on line)
Braille display option for Deaf/hard of hearing Supported by major screen reading programs but may be limited to a specific brand of display Can use with NVDA free
Using Voice Commands Built-in • Because the synthesizer voice is its own sound source there is often a conflict using a screen reader and voice activation together. • Apple’s Siri • Dolphin Guide (screen reader plus voice activation option) • CDESK (a full computer system)
Dragon Can combine JAWS and JSay Dragon has a screen reader function to read back what was written out loud, but because this is after dictation not as effective Works well on smart phones
Scan and Read Software with its own voicing system to scan, read and manipulate text with a PC or MAC Examples: • Kurzweil • Open Book • Scan and Read Pro
Trying it Out Many software programs are quite costly so best to try first. Most have demos for 30 to 60 days to download from the web or by ordering a CD.
Compare/Contrast For blind users: A study of 5 screen readers and 3 operating systems was done in 2011, link to full webinar and transcript Equal Access to Software and Information (EASI) Webinar
Resource: Blind & Low Vision The Visually Impaired Information Center just updated their resource list for blind low vision users. A print copy is available or you can check their web page for a list of computer consultants and trainers and service providers and much more!
Resources: Learning Disabilities LD online is an excellent resource for products. You might also want to use the freedom stick which has free useful apps.
Demonstration vs. Evaluation In person Demos are valuable to compare contrast options, look at features for functional use, and explore optional screen reading voices. An assessment/evaluation may be needed for a third party to purchase, for ongoing training, or to better identify the best fit for the end user for education or a work setting.
Accessibility issues Every time an operating system is updated, a program is changed, and a web site is developed the screen reader must keep up. This can be especially problematic on a job site.
Universal Design The flexibility of screen readers across disabilities, the fun of using voice activation and the increased demand by end users are moving us toward universal access but there’s a long way to go!
