Surfing the web is an entirely different experience for someone with a physical disability. Something as simple as buying an outfit online or sending messages to co-workers can be challenging on many sites and web applications for someone who can't see the screen or has trouble moving a mouse.
"It's pretty rare for me to go to a website and not encounter any accessibility issues," said Aaron Cannon, a website developer who is legally blind.
Last fall, Cannon seized an opportunity to help change how the disabled experience the internet when he and several others started a Minneapolis consulting group that helps companies and their web developers make their sites more accessible.
The company, called Accessible360, audits and tests websites to determine how accessible they are and recommends improvements.
With a staff of about a dozen people in its Uptown offices, Accessible360 provides training for technical staff to share best practices. It also offers a subscription service to continually monitor sites and help make sure they stay accessible.
Some common accessibility pitfalls are when sites don't have PDFs that are readable so that screen readers can pick up the text and when text is embedded in images in a certain way that it also is not able to be read. For those with motor skill difficulties, the "tab" key is often used for navigation to highlight different elements of a web page, but sometimes that function is disabled. Many of these are easy fixes that a developer who is versed in accessibility can avoid before they become problems.
"The fundamental issue is that there is a lack of understanding by the people building the websites in the first place," Cannon said.
Nearly 20 percent of Americans live with a disability, according to recent U.S. Census data. Some are born with a condition while others develop disabilities as they age.
