Screen readers helps people with ______________.

a) Blindness

b) Low Vision

c) Hearing Loss

A person with _____________ may be able to see large text like headings, but smaller text may be hard to read.

Do not use color alone to convey important information since users and make sure the important information is represented in the __________.

For people who have ___________, faces and objects appear blurry it is difficult for them to distinguish specific features.

Do not use color alone to convey important information since users customize colors based on what is best for them.

Text that is too close in color or luminance (brightness) to the background can be ______________.

Screen magnification like ZoomText or MAGic is used for what kind of disease?

To attempt to remedy the effects of low contrast and bright areas, users may modify the colors in

A) Operating system

B) Web browser

C) Screen Reader

D) Color Contrast Analyzer

It is best to place popups, alerts, error messages, and other similar messages near the visual focus, to make sure users don't miss them.

The most prevalent form of color-blindness, though, is ____________ blindness.

How does blind people overcome challenges faced in Information Communication and Technology domain?

Low vision isn't a single condition but it is a broad category encompassing many different conditions, with varying degrees of vision impairment.

Under the Consumer & Industrial Products domain what are the solutions provided to users who cannot read books, magazines, posters, postal mail, or other printed materials?

A) Optical character recognition software can convert scanned images of text into digital text readable by screen readers. The accuracy of the conversion depends on the quality of the original document, as well as font choices, line spacing, and the quality of the conversion software itself.

B) Information can be placed online or in other digital formats to allow blind people to read the materials using their own assistive technologies.

What is the condition these diseases are related to?

• Blur
• Blur with Low Contrast
• Cataracts
• Diabetic Retinopathy
• Glaucoma
• Hemianopia
• Macular Degeneration
• Retinal Detachment

How does the blind people overcome the faced due to Information and Communication Technology (ICT)?

(e.g. cannot see electronic interfaces)

People with low vision can see, but their vision is still quite far from perfect even with powerful corrective lenses.

The main categories of blindness are

A) visual disabilities,

B) low vision,

C) auditory disabilities,

D) motor disabilities,

E) cognitive disabilities,

F) seizure disorders

G) color blindness

For people with low contrast vision, or low color vision, colors may not be easily visible, and may be hard to distinguish from each other.

Self-voicing interfaces (on ATMs, kiosks, transportation systems, etc.) and applications can communicate to users without the need for a screen reader, but these are appropriate mostly for broadcasting information, because they usually do not interact with the interface or content as screen readers do.

Under the Consumer & Industrial Products domain, what are the solutions for people who cannot see or feel the controls on flat interfaces on consumer devices such as microwaves, ovens, dishwashers, etc?

A) Alternative interfaces with knobs or other tactile controls

B) Audio interfaces

C) Remote control through applications on mobile devices

The challenges faced by blind people who cannot see digital or electronic interfaces (computers, automated teller machines (ATMs), mobile devices, airport kiosks, televisions, printers, copiers, phones, GPS devices, etc.) are part of which domain?

Those who have low vision may be unable to see well enough to drive or read most printed text unless they enlarge it.

What technology is used to communicate to users without the need for a screen reader, for broadcasting information, they usually do not interact with the interface or content as screen readers do.

The definition is not intended to provide a functional definition of low vision, meaning it does not disclose what a person can or cannot see.

What does blind people use Screen Readers?

A) Screen Readers can read interfaces and content out loud to users

B) Screen Readers provide gestures for blind people to learn

C) Screen Reader provide speech transcript

D) By announcing colors and font sizes.

Screen readers can read interfaces and content out loud to users by converting digital text to synthesized speech, but only if they have been designed to be accessible. Screen readers do not announce text styles such as font, color, size, bold, and italic.

Under the Consumer & Industrial Products domain, what are the solutions for users who cannot read the text on the containers or packaging for consumer items such as medicine, toothpaste, shampoo, sunscreen, hand cream, personal care products, foods, drinks, candy?

Embossed braille (or braille stickers) on packaging and product containers help consumers identify items both in the store and after purchase

________________ use screen readers to convert digital text to braille.

For the challenges where small text is hard to read, ________________ can supplement screen magnifiers by reading interfaces and content out loud to users through synthesized speech, but only if the digital information has been designed to be accessible.

Blind person use the web with the help of a software program called a _____________.

Reading small text is an extremely difficult task for a user with ___________.

According to the U.S. definition of blindness, a person who has a visual acuity

A) of 20/200 with corrective lenses or who has a field of vision (what can be seen in front of the person) that is 20 degrees in the eye that has the best vision is considered to be legally blind.

B) of 200/20 with corrective lenses or who has a field of vision (what can be seen in front of the person) that is 200 degrees in the eye that has the best vision is considered to be legally blind.

C) of 200/200 with corrective lenses or who has a field of vision (what can be seen in front of the person) that is 2 degrees in the eye that has the best vision is considered to be legally blind.

D) of 20/20 with corrective lenses or who has a field of vision (what can be seen in front of the person) that is 20 degrees in the eye that has the best vision is considered to be legally blind.

Stand-alone screen readers are much more useful as compared to Screen readers bundled with screen magnifiers.
