Sensory Characteristics
Avoid relying on sensory characteristics, such as shape, size, or visual location. For example, “Click the green button” will not be useful to screen reader users or some users who are color blind. Instead, use “Click on the green button labeled ‘submit'” or simply “Click the ‘submit’ button”. Similarly, “Use the form on the right” could be changed to something more descriptive such as, “Use the search form on the right.” Other examples include prompts such as “Click the larger button,” “Select a state on the east coast on the map”, “Instructions are included in the sidebar”, etc. Purely auditory cues (“Click ‘Continue’ after you hear the beep”) should also be avoided.
