What kinds of disability(thus called Accessibility users) are we looking at?

People with disabilities are just as diverse as people without disabilities, and so are their disabilities. The key lesson here is to think beyond your own computer and how you use the web based on the thought that, the digital technology that you're using, how should that respond to a disable person !

People with visual impairments

People with visual impairments include people with blindness, low-level vision, and color blindness. Many people with visual impairments use screen magnifiers that are either physical magnifiers or software zoom capabilities. Most browsers and operating systems these days have zoom capabilities. Some users will rely on screen readers, which is software that reads digital text aloud.

People with hearing impairments

Otherwise known as people with auditory impairments or deaf people, this group of people has either low hearing levels or no hearing at all. Hearing-impaired people do use ATs (see Assistive Devices for People with Hearing, Voice, Speech, or Language Disorders), but there are not really special ATs specific for computer/web use

People with mobility impairments

These people have disabilities concerning movement, which might involve purely physical issues (such as loss of limb or paralysis), or neurological/genetic disorders that lead to weakness or loss of control in limbs. Some people might have difficulty making the exact hand movements required to use a mouse, while others might be more severely affected, perhaps being significantly paralyzed to the point where they need to use a head pointer to interact with computers.

People with cognitive impairments

Cognitive impairment refers to a broad range of disabilities, from people with intellectual disabilities who have the most-limited capabilities, to all of us as we age and have difficulty thinking and remembering. The range includes people with mental illnesses, such as depression and schizophrenia.

An issue may also have sub-tasks that can be assigned and tracked individually, as well as issue level security to restrict the issue to select members of your team. On this page, you'll learn more about creating and converting issues and sub-tasks, and setting issue level security. If you are looking to import multiple issues (and sub-tasks) using a CSV file, you can find the import process explained in more detail  here .

  When you are playing the role of Accessibility tester, you're not only helping the Stakeholders to be 508 compliant on their Web Application or any other Digital Media/ Technology but also you are helping a huge group of people who, otherwise wouldn't be able to use these Web Application or Digital Media/ Technology. Following points are to be considered very important when you are engaged in 508 Testing AKA Accessibility Testing: Whether an application provides keyboard equivalents for all mouse operations and windows? Whether tabs are logically ordered to ensure smooth navigation? Whether shortcut keys are provided for menus? Whether response time of each screen or page is clearly mentioned so that End Users know how long to wait?   Whether all labels are written correctly in the application? Whether color of the application is flexible for all users? Whether images or icons are used appropriately, so it's easily understood by the end users? Whether an application has a...
