Web Accessibility

As the the web becomes an important resource for many aspects of life, it is essential that it be accessible to those with disabilities.

What Is Accessibility?

There are several government organizations and non-profits working to set standards on accessibility for sites and software.

Below are some useful sites dedicated to providing web accessibility tools, services, and information:

TechMatrix is a product of the National Center for Technology Innovation (NCTI) and Center for Implementing Technology in Education (CITEd) and offers assistive and learning technology products for students and others with special needs and offers thorough information to make informed tech decisions.

Able Data provides objective information on thousands of assistive products available to consumers, organizations, professionals, and caregivers within the United States. On the site, you can research information on assistive products, as well as information about the companies that make and sell them.

The Center for Accessible Technology provides access to computers for people with disabilities, so that children with disabilities can succeed in school, adults with disabilities can find and keep jobs, and all people with disabilities can benefit from the digital revolution. The Accessible Technology Coalition maintains a website to help people with disabilities  and those who work with them, tomake informed decisions about assistive technology.

Accessibility Features on Your Operating System

Adaptive Hardware

Adaptive hardware devices can additionally be used to make accessing the computer and navigating the web easier for those with disabilities. Below is a list of such devices available for purchase.

Adaptive Hardware for Vision Impairments:

  • Braille Devices such as printers, embossers, readers, portable displays, and note-taking devices.
  • Closed Circuit Televisions (CCTVs) provide video magnification of print and other materials. Users can place a book, image, or text underneath a camera or lens and the magnified image is rendered on a video screen.
  • Headsets allow users to hear audio text privately, while the attached microphone allows for hands-free use of voice recognition software
  • Large Monitors of 20 inch or more provide more room for enlarged text and graphics
  • Magnabrite Magnifier is a solid acrylic 4x light-gathering magnifier. It intensifies the light that passes through it, making the magnified subject clearer and nearly four times brighter.
  • Scanners with optical character recognition (OCR) software convert print materials in to electronic text which can be read by the computer.
  • A Tactile Image Enhancer creates an upraised impression of an image on specially made paper, allowing people with visual difficulties to feel the contours of the image.

Adaptive Hardware for Mobility Impairments:

  • Adjustable Height Tables and Chairs can help with strained or injured backs.
  • Special Mice, Keyboards, and Pointing Devices that are more ergonomic can make it easier to navigate the computer and more comfortable on your body.
  • Tablet PCs can capture handwritten notes allowing users to write directly on the screen (with a non-ink digital pen) while the tablet translates the handwriting into keyboard-style text.
