  • Visually Impared Screen Reader For Mac
    카테고리 없음 2021. 6. 10. 03:45

    If you are a Mac user, Apple includes a screen reader called VoiceOver. If you have some functional vision, but sometimes struggle with reading certain text, a simple screen reading program may do the trick and will likely be easier to learn, since you merely select the text you want to be read aloud. GW Micro, the makers of the Window-Eyes screen reader, have released a free version for users of Microsoft Office 2010 and above. The free version is the same as the paid-for version of Window-Eyes except that it does not include the same voices, has no print, braille or audio CD documentation, and comes with little free technical support.

    Visually

    iPhone isn’t just a powerful, personal device. It’s also an incredibly useful one if you’re blind or have low vision. VoiceOver describes exactly what’s happening on your iPhone. Magnifier works like a digital magnifying glass. And you can also choose from a range of color filters to support your specific vision needs.

    VoiceOverHear what’s happening on your screen.

    VoiceOver is a gesture-based screen reader that lets you enjoy using iPhone even if you don’t see the screen. With VoiceOver enabled, just triple-click the Home button to access it wherever you are in iOS. Hear a description of everything happening on your screen, from battery level to who’s calling to which app your finger is on. You can also adjust the speaking rate and pitch to suit you.

    Visually

    VoiceOverWorks with every built-in app. And many third-party ones.

    Because VoiceOver is integrated in iOS, it works with all the built-in iPhone apps. You can create custom labels for buttons in any app — including third-party apps. And Apple works with the iOS developer community to make even more apps compatible with VoiceOver.

    VoiceOverNavigate VoiceOver with simple gestures.

    You can control VoiceOver using a simple set of gestures. Touch or drag your finger around the screen and VoiceOver tells you what’s there. Tap a button to hear a description, then double-tap to select. Or flick left and right to move from one element to the next. When you interact with an element, a black rectangle appears around it so sighted users can follow along. When you prefer privacy, you can activate a screen curtain to turn off the display completely, but still hear all that VoiceOver has to say.

    VoiceOverType and edit with speed and accuracy.

    With VoiceOver enabled, each character on the keyboard is read aloud as you touch it, and again when you enter it. A flick up or down moves the cursor so you can edit precisely. To help you type more quickly and accurately, iOS supports multiple character input methods — including handwriting — and corrects misspelled words. Enable Speak Auto-text and you hear a sound effect and the suggested word spoken. Keep typing to ignore it, or tap the space bar to have your iPhone type it for you.

    VoiceOverIt can even describe images to you.

    VoiceOver can describe images to you, such as telling you if a photo features a tree, a dog, or four smiling faces. It can also read aloud text in an image — whether it’s a snapshot of a receipt or a magazine article — even if it hasn’t been annotated. And in the Photos app, you can touch to explore the facial expressions of people in your photos. Just tap the image with three fingers to have VoiceOver describe what’s there.

    VoiceOverA virtual controller with customizable commands.

    VoiceOver features a virtual control called the rotor. Turning the rotor — by rotating two fingers on the screen as if you were turning an actual dial — lets you efficiently move through a web page or document. When you’re on a web page or PDF, turn the rotor to hear settings like “headings,” “links,” and “images.” Then flick to choose how you navigate the page. For example, you can skip from one heading to the next.

    VoiceOverDirect braille entry without a braille display.

    VoiceOver includes systemwide support for braille chords in 6 and 8 dot braille, enabling direct braille entry without the need for a physical braille keyboard. The braille keyboard is available in the rotor, so you can use it to type text, unlock your iPhone, launch apps, and find content in apps like Music.

    VoiceOverUse a braille display for input and output.

    iPhone is fully compatible with more than 70 refreshable braille displays. You can connect a Bluetooth wireless braille display to read VoiceOver output, including contracted and uncontracted braille and equations using Nemeth Code. When you edit text, your display shows the text in context, and your edits are seamlessly converted between braille and printed text. And braille displays with input keys can be used to control your iPhone when VoiceOver is turned on.

    VoiceOverHear it the way you say it with the Pronunciation Editor.

    The Pronunciation Editor allows you to create a list of words or phrases along with the phonetic ways you want them to be pronounced. With VoiceOver turned on, these words and phrases will then be read aloud with your preferred pronunciation in documents, messages, web pages, and other text.

    Audio DescriptionsHear the details in every scene.

    Watch movies with detailed audio descriptions of every scene on your iPhone. Movies with audio descriptions are displayed with the AD icon in the iTunes Store.

    iPhone also lets VoiceOver users access closed caption and subtitle tracks audibly or through their braille displays.

    Display AccommodationsCustomize your view so it’s easier on the eyes.

    iOS lets you invert colors, reduce white point, enable grayscale, or choose from a range of color filters to support different forms of color blindness or other vision challenges. You can select a common preset or fine-tune the color tint and hue to customize a display setting that works for you. With the Smart Invert Colors setting, iOS automatically recognizes when a piece of media is using a dark color style, so you can reverse the colors of the display without affecting the look of images, videos, and certain apps. And once you set your filters, the settings apply to everything that appears on your iPhone.

    ZoomMake your screen up to 1500 percent bigger.

    Zoom is a built-in screen magnifier that works wherever you are in iOS. And it works with all apps from the App Store. Turn Zoom on for full-screen or picture-in-picture view, allowing you to see the zoomed area in a separate window while keeping the rest of the screen at its native size. You can adjust the magnification between 100 and 1500 percent and access multiple filter options in either view. While you’re zoomed in, you can use all the familiar gestures to navigate your iPhone. And Zoom works with VoiceOver, so you can better see — and hear — what’s happening on your screen.

    Font AdjustmentsApps can automatically adapt to larger type.

    When you activate Larger Dynamic Type, the text inside a wide range of apps, including Calendar, Contacts, Mail, Messages, Music, Notes, and Settings, and even some third‑party apps, is converted to a larger, easier‑to‑read size. Apps adapt to accommodate larger font sizes so text remains legible and clear as it grows. And you can choose bold text to make the text heavier across a range of built‑in applications.

    MagnifierUse your camera to get a closer look.

    Magnifier works like a digital magnifying glass. It uses the camera on your iPhone to increase the size of anything you point it at, so you can see the details more clearly. Use the flash to light the object, adjust filters to help you differentiate colors, or snap a photo to get a static close-up.

    Speak ScreenFrom emails to books, let your iPhone read to you.

    If you have a hard time reading the text on your iPhone, use Speak Screen to read your email, iMessages, web pages, and books. Turn on Speak Screen and swipe down from the top of the screen with two fingers, or just tell Siri to Speak Screen and have all the content on the page read back to you. You can adjust the voice’s dialect and speaking rate, and have words, sentences, or words within sentences highlighted as they’re being read.

    SiriStreamline the things you do every day.

    Magnifying Readers For Visually Impaired

    Siri helps you with the things you do every day.* Siri can send messages, place phone calls, schedule meetings, and even turn on and off VoiceOver, Guided Access, and Invert Colors. And because Siri is integrated with VoiceOver, you can ask where the nearest sushi restaurant is and hear the answer read out loud. With Siri Shortcuts, you can now cue multi-action commands with a simple custom phrase. If you’re commuting, for example, say “Heading Home” to get directions, bring up a favorite podcast, and adjust your thermostat — without having to go into each individual app.

    DictationYou say it. iPhone types it.

    Dictation lets you talk where you would type. Tap the microphone button on the keyboard, say what you want to write, and your iPhone converts your words (and numbers and characters) into text. So it’s easy to type an email, note, or web address — without typing at all.

    Accessibility ShortcutsGet quick access to your favorite features.

    Control Center is customizable, so you can easily add and organize shortcuts for the tools and settings you use the most. For example, you can add a quick link to Magnifier so it’s always handy, or add a Text Size control so you can adjust text size on the fly without leaving the app you’re using. You can also turn on Guided Access or get to all the Accessibility Shortcuts you have enabled.

    After braille, no invention has enabled blind and visually impaired people to communicate as effectively as the assistive technologies that make computers and the Internet accessible. Digital technology has also given those that are blind ever-expanding opportunities for personal and professional growth.

    To make such a highly visual environment accessible to those unable to see a computer monitor, assistive technology must do two things:

    1. Enable users to read all onscreen content, whether emails, spreadsheet columns, application toolbars, or photo captions
    2. Provide a means to navigate one's keyboard and desktop, open and use programs, and browse the web

    Audio Readers For Visually Impaired

    The two technologies that make this possible are screen access- and magnification software programs.

    Screen Access Software

    Screen readers give voice to computers through applications that synthesize written words and keyboard commands into human-sounding speech of the sort you might hear on an automated phone and voicemail systems.

    The most popular screen access program is JAWS for Windows, developed by Freedom Scientific, which supports all Microsoft and IBM Lotus Symphony applications.

    JAWS reads aloud what's onscreen, beginning the with installation instructions, and provides key command equivalents to mouse functions so blind computer users can launch programs, navigate their desktop, read documents, and surf the web using just their keyboard.

    For example, rather than double-clicking on the browser icon, a blind person might press in succession:

    • 'Windows' key to reach the Start menu
    • 'P' to access their program list
    • 'I' for all applications beginning with 'I'
    • 'Down arrow' to scroll through the list
    • 'Enter' once they hear 'Internet Explorer.'

    It sounds painstaking, but screen readers speed navigation by providing shortcuts and audible cues. For example, the arrow keys enable users to quickly cycle through desktop items or section headings on a website. Pressing Insert + F7 displays a list of all links on that page. On Google, or on any site with forms, JAWS sounds to indicate the cursor is in the search box or has advanced to the next text field.

    In addition to converting text to speech, another crucial function JAWS and similar programs provide is output in braille. This function enables braille readers to view documents on refreshable braille displays or download them onto popular portable devices such as BrailleNote.

    The main drawback with screen readers is the price. The American Foundation for the Blind notes that prices can range up to $1,200. One can, however, download free Windows accessibility software, or purchase an all-in-one PC accessibility solution such as CDesk.

    Serotek offers System Access to Go, a free, web-resident version of its flagship screen reader. After creating an account, users can make any computer connected to the Internet accessible by simply logging in and pressing Enter.

    Screen Magnification Software

    Screen magnification programs enable visually impaired computer users to enlarge and/or clarify what's displayed on their monitor. In most programs, users can zoom in and out with a keyboard command or flick of the mouse wheel.

    HumanWare's ZoomText Magnifier, one of the most popular products, magnifies screen contents from 1x to 36x while maintaining image integrity. Users can zoom in and out at any time with a turn of the mouse wheel.

    ZoomText provides controls so users can adjust:

    • Color, contrast, and brightness
    • Letter thickness and spacing
    • Size of the often-lost cursor and mouse pointer.

    ZoomText users wishing to use two open applications at the same time can magnify portions of the screen by opening one of eight 'Zoom' windows. An enlarged viewing area can also be expanded onto two adjacent monitors.

    The degree of vision loss usually determines which solution a blind person uses. People with no or severely limited vision use screen readers. Those with sufficient vision to read print use magnification programs.

    Apple Integrates Speech and Magnification

    Not long ago, all the assistive computer technology for the blind was PC-based. No longer.

    Nvda Screen Reader For Mac

    Apple has built both screen reading and magnification into its Mac OS X operating system used in the latest versions of its iPad, iPhone, and iPod. The screen reader is called VoiceOver; the magnification program is called Zoom.

    VoiceOver 3 includes a standard set of hand gestures that can be used to navigate among different windows, menus, and applications. It can also integrate more than 40 popular braille displays via Bluetooth.

    Zoom is activated using keyboard commands, onscreen buttons, and via mouse or trackpad and can magnify text, graphics, and motion video up to 40 times without loss of resolution.

    The Need for Training

    No matter which technology one chooses, a blind person should expect to buy a computer and screen reader and learn via some sort of training. The sheer number of commands within JAWS constitutes a new language. You could figure out a few things but likely wouldn't get as far as you would with some formal training.

    Training sources include:

    Jaws Screen Reader For Mac

    • Webinars on manufacturer sites and institutions such as the Hadley School for the Blind
    • Training materials in accessible formats from companies such as Handy Tech North America in Columbia Heights, Minnesota
    • Post-assessment programs through a vocational rehabilitation agency or hospital
    • Phone tutorials and talk-throughs from experts such as Roger Cusson of Seeing Hands Enterprises, Lewiston, Maine
    • Local continuing education courses and computer user groups.

    Training and product prices vary. One should contact state agencies, including vocational rehabilitation, commissions for the blind, and special education departments to explore assistive technology funding options.
