Structure

​

To avoid distraction information should be kept simple, without any unnecessary details. There should also be a consistent layout of information so it can be easily followed (11). Additionally, the information, navigation and content should all be predictable and provide feedback (5). Between each section, blank spaces should be used to separate content and support attention (12).

​

Text and headings

​

Text should be easily readable by using fonts such as sans-serif and keeping the words at size 12 minimum. Additionally, important information should be in bold to emphasise its importance (11). Large blocks of text and long paragraphs should be avoided, as they disrupt the flow and can lead to information overload. Alternatively, text should be broken up into smaller sections and be separated clearly by headings (12).

Interaction

​

Allowing websites to be resized is an important factor in accessibility, meaning they can be accessed on any device (5). This may be important for individuals with ASD, as using sites on a mobile phone provides a different level of interaction through a touch screen, which could promote higher levels of engagement (5). It is important with this to have an appropriate level of sensitivity, that doesn't cause frustration or errors such as accidental touch that can cause unwanted re-directions (12).

Navigation

​

The navigation of information should be easily followed by using a straightforward structure, where links are easily found and labelled. It is also important to limit the use of too many links to avoid confusion (11). Additionally, sites should be very responsive and provide quick access to links and content (5). Navigations back to the home page, exiting the current link and help buttons should be available and visible on every page (12).

Things to avoid

​

Visual or information overload should be avoided. Background sounds, moving images or text, horizontal scrolling and flashing images should be avoided to prevent sensory overloading (11).

Colour

​

Colour choice should be considered carefully, predominate colours such as red should be avoided (11), as well as yellow as this can cause sensory overloading from the high luminance volume. Colours such as brown, and especially green are favoured. Additionally, effective colour contrast should be utilised to ensure access to content (13).
