Making your website accessible to the disabled helps everyone

The information super highway is open for everyone to travel but the journey for the disabled all too often ends in reaching an exit ramp and finding it closed. Making your website accessible usually requires minimal time and effort, and not only expands your audience to the disabled, but also benefits everyone.

The Internet has been a godsend to those with disabilities by providing access to information that was impossible in the past. However, too many of us create websites, post to blogs, and upload videos without ensuring they are accessible to people with disabilities. Before learning how to make your site accessible, it helps to first understand the obstacles to accessing the Internet that different disabilities present and the assistive technologies that are used to overcome them.

Disabilities and challenges


Challenges: Cannot hear sound from video and audio content.

Assistive Technologies Used

  • Captions
  • Transcripts


Challenges: Dependent on type and severity of disability. Some people simply cannot read small text. The blind are unable to see any visual content. People who are color blind cannot distinguish between elements differing in color alone.

Assistive Technologies Used

  • Screen-reader, which translates the text of a web page into speech or Braille.
  • Web browser that can enlarge text
  • Screen magnifier software


Challenges: Extreme difficulty or inability to use a mouse. The user must rely on some form of keyboard navigation.

Assistive Technologies Used

  • Mouth stick, which is a stick held in the mouth and used to type on a keyboard.
  • Voice recognition software
  • Sip and puff switch
  • Oversized trackball mouse

I can think of no better way to comprehend the struggles with web accessibility that people with various disabilities face, than listening to them describe their experiences as featured in the following two videos from WebAIM:

Steps for making your website accessible

You don’t need to be a web design expert to make your site more accessible to the disabled. The process results in pages that are well-designed, more user friendly, work better on mobile devices, and rank higher by search engines. Some of the steps that you or your web designer can easily implement are:

  • Caption or provide transcripts for video and audio content.
    Create transcripts with a word processor or text editor. YouTube provides instructions on how to use transcripts or caption files. A transcript contains only the text of what is said in the video, which will be automatically synchronized by YouTube. A caption file includes the time codes for when each line of text should be displayed. Special software also exists to create and add captions directly into your video file, including free programs such as Subtitle Workshop (Windows) and Aegisub (Windows/Mac/Linux). An added benefit of including a transcript with your YouTube video is that it will be indexed and searchable in Google. Make sure you let your audience know that your content includes captions or a transcript.
  • Provide alternative text for important non-text content.
    Use your web design software or blogging interface to type in alternative text for all important images and graphics so that it can be read by a screen reader. Avoid including alternative text for graphics that are purely decorative.
  • Use headers.
    Including headers in your content provides structure and levels of hierarchy. Screen readers can navigate from header to header and create a summary of a page based on headers. Be sure to use headers in the proper order, h1, h2, h3, etc.
  • Do not use graphics to represent text when plain text is suitable.
    A browser is capable of enlarging plain text and making it readable. Graphical text, when enlarged, might become blurry and unreadable.
  • Do not use unnecessarily small text.
    Keep text in a size that is easily readable. Although text can be enlarged with software, do not assume that everyone knows how to do so.
  • Use punctuation.
    Punctuation enables voice synthesizers to use correct cadences and produce more understandable speech.
  • Use descriptive link names rather than “click here.”
    Screen readers often create a list of links on a page, consisting only of the link text. Without any context, link names such as “click here” are meaningless.
  • Use enough contrast between text and backgrounds so the text stands out and is readable.
  • Do not use color alone to convey information.
  • Use an online tool to test your website’s accessibility.
    The tools produce reports that can help you identify problems with your web page’s accessibility. Much of the information could be difficult to understand for those not familiar with HTML and web design but, nevertheless, still worth a look for everyone. There are several online tools listed in the Resources below.

I have covered only the basics on how to make your website more accessible. For more in depth, technical information, check out the Resources links listed at the end of this posting.

I hope you are motivated to address web accessibility in your current and future websites and blogs. Doing so will not only open those exit ramps on the information super highway for the disabled but also improve travel for everyone. Please feel free to post your comments about your experiences.

Use Screencasts to Teach, Demonstrate, Sell

In just two days, the job would be over, but to me, the work unfinished. I’d been providing software training for the faculty at a small college during my two week consulting stay but more of them would need help after I’d gone. For those I would not meet, I wanted to find a way to recreate the training experience of sitting down with each of them at the computer. Creating a screencast allowed me to do just that.

A screencast is a video of the actions on a computer screen, usually including accompanying narration or captions that explain the on-screen activity. Screencasts are quick and easy to produce. They are commonly used for software tutorials, product demonstrations, and presentations. Videos are typically distributed online or on discs.

Screencasts offer advantages to both the instructor and learner over more traditional instructional materials. Instructors are able to demonstrate concepts, allowing the audience to learn by example. This can be much more effective than reading through pages of text and static images. Viewers benefit by accessing videos at their own convenience when they have the time and proceed at their own pace.  The control over starting, pausing, and replaying videos helps accommodate different learning styles. A screencast also provides a personal connection between the instructor and audience that is often missing in distance learning.

Without question, one of the most popular applications of screencasts is in training and education. Years ago, I first taught myself software such as Adobe Photoshop and Illustrator by viewing hours of training videos on discs. Companies such as and VTC offer hundreds of courses in software product training including graphic design, video, operating systems, programming, web development, and digital photography.  Courses are broken down into videos on different topics, giving the learner the ability to choose the video that addresses the specific issue at hand. Software publishers offering libraries of such videos can increase sales and reduce product support issues. Some other uses for screencasts are:

  • Presentations
  • Product demonstrations
  • Capture of live lectures and webinars
  • Explaining technical concepts
  • Website tours
  • Project Orientations
  • Software Reviews
  • Providing feedback for grading of assignments and tests

Making a screencast requires special software to record the screen activity and a microphone if you’ll be adding narration.  The process is simple. Run the screencast software. Start the application that you would like to record. Select the area of the screen to be captured. Capturing the entire screen is not necessary, only the relevant areas. After selecting the area, start recording. Run some tests to check audio levels and to be sure everything is working correctly before proceeding with the full recording. Record, save, and make any necessary edits to the video. Once your screencast is completed, the content can be delivered on a disc or online by publishing the file to either your own website or to a hosting site such as YouTube or Vimeo. In order to demonstrate the basic process of creating a screencast, I created…what else…a screencast, listed below:

Planning ahead can help you produce a good screencast and save time by reducing the number of takes and cutting down editing time. Poor quality audio could quickly turn away an audience. An expensive, professional microphone is not necessary to record decent audio. However, it is best to use an external microphone rather than one that is built into your computer. A good headset should produce sufficient results. Plan out what you are going to show by creating simple storyboard sketches. Write out a script for the entire screencast, if that’s your style, or make an outline at the very least. Before you begin recording, organize all of the files and materials you’ll need. Open up any applications you plan to use. Rehearsing can be helpful. It is often best to do multiple takes until you get it right rather than spending a lot of time afterward editing together multiple video clips. However, you might also consider leaving some of your mistakes in the video if viewers are likely to encounter the same problems. Audience attention spans tend to be very short. If your screencast is long, break it up into smaller segments and label each so that viewers can jump to the parts of interest.

Screencast software comes in two types: online, web-based tools, and full desktop applications that you install on your computer. Online tools are usually free but have limits on the video duration and output file size. Those limits can be removed by paying a fee. An online tool is a good choice for short screencasts.  The desktop applications are better suited for long screencasts because they are capable of doing everything: recording, editing, adding captions, arrows, and special screen highlighting. They are available in both free and commercial software but the free ones have some limitations and usually do not offer editing capabilities.

Screencast Date

It took me only a few hours to create my screencast for the college, which they now have as a valuable training resource available at any time. If you have something to teach, demonstrate, or present, consider sharing it with a screencast. The time spent can pay off in many ways for both you and your audience.

Free Alternatives to Commercial Software

The work kept coming in but the software I ordered to get it done sat in a pile of red tape. The situation lingered for months but fortunately, I found a solution: free software. I was able to locate free alternatives for nearly all of the commercial applications I was waiting for.

Free software exists for just about any type of application: word processors, antivirus protection, photo, video, and sound editors, computer backup, CD / DVD burners, 3D modelers, etc.  Check out the list of popular titles at the end of this entry.  Quality is dependent on the particular product, ranging from buggy, beta releases to full-featured, robust applications that can meet or exceed rival commercial software.

It is important to understand that there are different types of free software. They are generally categorized as freeware, shareware, or open source.  Freeware usually refers to software that can be downloaded and used for free but with little or no support and no access to its source code. Shareware can be tried for free but you are expected to pay for it if you continue to use it after a trial period. The shareware developer has full control of the intellectual property and is responsible for providing support and enhancements. Source code access is restricted. Open source software is released with its source code and is free to use, modify and redistribute. It is supported by an online community of developers and users.

So why would you want to use free software? If you’re interested in learning a particular type of application, you can download a program for free and dive right in without any financial investment. Afterward, you might stick with the free one if it suits your needs or go further and purchase a commercial program. Sometimes a commercial application might be too complicated, incompatible with your computer’s hardware, too buggy, or causes conflicts with other software. I once had problems with two different commercial antivirus programs so I decided to switch to a free one. Unlike much commercial software, open source is usually updated frequently and problems are quickly rectified. Finally, because there are no licensing costs you can use it on as many computers as you’d like.

Free software is not without its downsides. In the case of open source, it is often developed by programmers for use by other programmers and can be much less user-friendly than commercial software. Unlike commercial software, there is no one-on-one support available. Instead, support is provided through forums and there is no guarantee that your particular issue will ever be resolved. Development of an open source program could cease indefinitely without warning, or never make it past a beta stage. It’s a good idea to check how long a program has been around before deciding to invest a lot of time in it.

Where can you find free software? An excellent place to start is at where you can search from thousands of open source titles. Check out the links I’ve listed below for other good sites.

Eventually, I received all of the software that I requested on my job but some of the free applications I’d found were so good that I continued to use them alongside the commercial ones. Regardless of whether you’re in a bind like I was, exploring the free software available is well worth the effort. You can’t beat the price!
