Best Practice 1.5 – Do not solely rely on sensory characteristics for instructions (Advanced level)


Do not rely solely on sound, shape, size or visual location to provide user instructions.

 

Before Rectification
A sample mobile application page with an arrow pointing to the right.
In this example, it is only understandable to a person who can see that next page button. This will not be understandable to a visually impaired person.
After Rectification
A sample mobile application page with instructional text added, and the arrow is now labelled as “Next”.
The correct way to do this is to also label the button or provide a text alternative to the button and ensure clear instructions are in place to tell people which button to use and how to use it.
