When you think of technology from the perspective of people who are blind or have low vision, you can think of two broad categories:

General technology: such as computers, smartphones and cell phones, GPS devices, etc.
Assistive technology: items designed specifically to help people with vision loss or other disabilities, including everything from screen readers for blind individuals or screen magnifiers for low-vision computer users, video magnifiers and other devices for reading and writing with low vision, to braille watches and braille printers.

AFB's goal is to provide you with the information you need to learn about available technology and even discover new ways to use technology to enhance your everyday life. We're pleased to provide you with:

AccessWorld®: Technology and People Who Are Blind or Visually Impaired, AFB's monthly online technology magazine with reviews of technology products and online resources for people with vision loss—a publication that is edited and reported by experts who are blind or have low vision
A searchable listing of assistive technology and independent living products
Tips on selecting and using everyday technology, like computers and accessible cell phones

Highlights of AFB's Work on Accessible Design and Technology Issues

Advocacy on public policy issues like digital inclusion, accessible transportation options, and more
Research into issues like the impact of COVID-19 on access and inclusion, as well as the workplace technology barriers faced by individuals who are blind or have low vision
AFB Consulting, a branch of AFB that works with clients across the retail, telecommunications, finance, education, and technology industries to advance their accessibility and inclusion goals

Technology is everywhere in today’s society—from the computer you are using to visit FamilyConnect to the debit card you used at the grocery store this morning to the remote you click to change channels on your television. Your visually impaired child will use technology in all facets of her life. Sometimes it will be the everyday technology that all people use; sometimes it will be assistive technology, and sometimes the two will overlap.

As your child grows, her technology needs will change. At the same time, the technology available to her will be changing as well. To help your child make the best use of both global and assistive technology to maximize her independence, you will need to know about these ever-changing options. It is important to keep in mind that there is no one single “miracle” tool. To achieve success in school and later in the world of work, people who are blind or visually impaired need access to a toolbox filled with a variety of tools so that they can select the appropriate tool for any given task.

Some children may need only a few assistive technology devices, while others may benefit from using several in combination. The descriptions of technology on FamilyConnect are offered only to help you become familiar with the different types of assistive technology that exist, not to recommend any one product as appropriate for your child. To know what assistive technology tools are right for your child, you will want to consult with a teacher of students with visual impairments and other educational team members. If your child is already in grade school, she may benefit from an assistive technology assessment to determine what tools are appropriate to help her access information and keep up with her schoolwork.

Some Types of Assistive Technology

There are a number of different ways to categorize assistive technology tools. One simple way is to separate devices that use lenses to enhance vision from those that don’t and to reserve a special category for so-called high-tech devices.

Non-Optical Devices

The term non-optical device is sometimes used to refer to the simplest tool that generally involves no lenses, computers, or electronics. These tools enhance a child’s use of her vision. Examples of non-optical aids include:

A reading stand which brings material closer to a child’s eyes
Bold markers for writing
Dark-lined paper, which is easier to see when writing
A large-print calculator to use when working math problems
A hat or visor to decrease the glare of overhead lights or the sun

Optical Devices

Optical devices, sometimes known as “low vision devices,” use lenses to help people make better use of their existing vision. They include various types of magnifiers and telescopes. An electronic device, known as a video magnifier or closed-circuit television system (CCTV), which uses a camera to project an enlarged image on a TV screen or monitor, is also considered an optical device.

“High-Tech” Assistive Technology

Many people reserve the term assistive technology for equipment and devices that provide access to the environment and print information using computer hardware and software and other electronic equipment. Thus a video magnifier can be considered both an optical aid and a “high tech” piece of assistive technology.

Different kinds of software programs help people who are visually impaired get access to the information on a computer. Screen magnification programs enlarge the image on the computer screen, while speech-reading software is able to read the text aloud.

What Tools Different Children May Use

Keep in mind that the tools which will be used by any one child will be individualized for that child’s visual abilities, cognitive abilities, and needs at home, school, and in the community. The following lists illustrate the array of tools any one child may use.

A child with low vision might use these tools:

eyeglasses or contact lenses
a handheld or stand magnifier
a slant board for bringing material closer when working
colored overlays to put over printed material to provide better contrast
bold-lined paper to help stay on the line when writing
a bold marker for writing
a calculator with a large-print display
a digital recorder
a computer with screen enlargement software
a smartphone or tablet
a video magnifier

A child who is blind might use these tools:

a braillewriter
a refreshable braille display
a slate and stylus
raised-line paper for writing or graphing
a signature guide used to position a pen when signing one’s name
a calculator with voice output that speaks what is on the screen
a digital recorder
a talking dictionary
a computer, smartphone, or tablet with screen reading software
an audio book player

A child who has multiple disabilities might use a combination of the tools for children with low vision and blindness, and in addition, may use:

a switch to operate a toy or appliance
a communication device that speaks when a button is pressed
a communication book that has pictures, raised symbols, print, or braille in it that the child uses to express herself

What are low vision assistive devices?

What are some low vision aids? Some examples of low vision aids are magnifiers, reading glasses, video magnifiers, screen readers, portable electronic magnifiers, and assistive technology such as eSight.

What are assistive technology for visually impaired students?

Portable Magnifiers They have braille or QWERTY keyboards for input and a synthesized voice and/or braille display for output. Braille notetakers and other devices with refreshable braille displays can also be use to read materials. Portable book readers allow individuals to access specially coded files via speech.
