Accessibility

According to scopes Family Resources Survey 2015/16 there are 13.3 million disabled people in the UK. That’s approximately 20% of the UK’s population, that’s a large and significant number that must be considered when developing and interaction based idea.

 

When developing, for this example, a website, creators must consider users who suffer from Visual, Auditory, Speech, Cognitive and neurological disabilities. So, creating a website that is accessible means that users with disabilities can navigate, contribute, interact and perceive to the website and other web based sites. Not only would making your website accessible benefit disabled users but also users who are older.

 

There are ways that a website can be made more accessible for users such as:

ALT Tags

ALT tags provide a description of an image that has been hovered over by the mouse. This feature is used for users with screen readers (A feature which describes the image through a synthesised voice).

An example of an ALT tag. The users mouse is hovered over an image, a description box describing the image is underneath the mouse cursor.

Abbreviations

Abbreviated phrases are useful for some users in everyday life as it eliminates the need to read more than they need. If they know the abbreviation, then they understand what is being said. However, for users that are visually impaired or have a cognitive disability then abbreviations can a hindrance.

An example of how an abbreviation can be made accessible is through a screen reader. Instead of D.A.R.P.A being spoken as it was a single word, the abbreviation is instead spoken in detail. So instead of “D.A.R.P.A” it would become “Defence Advanced Research Projects Agency” through the use of a screen reader.

 

Link Descriptions

Link Descriptions describe the link through an alt tag when hovered over by the mouse, they can also be described through screen readers. This gives a better description to allow users to visit the correct links.
