The following is some useful guidance to consider when producing content for computer information screens to ensure they are as accessible as possible.
It is good practice to include onscreen contact details for someone users may contact if they are having problems with the accessibility of a screen.
Try and give at least two methods of contacting this individual, such as address and email, or email and phone number.
It is also important that screens are kept updated so that they display the latest information.
The format of your information is equally important:
- Use a sans serif font, such as Arial or Verdana - avoid using Times New Roman.
- Use as large a font size as possible - not less than font size 18.
- Ensure a high contrast between text and background.
- Try and use a darker font on light background rather than light font on dark background. This is preferable for most users with dyslexia, although some users with visual impairments may find the reverse of light font on a darker background to be more accessible.
- Avoid underlining and use of italics – use bold if you want to emphasise an item.
- Avoid justified or centred text – left aligned is best.
- Avoid over cluttering the screen with information or making it too 'fussy'.
- Ensure sufficient space between lines.
- Avoid moving or scrolling items. If items are moving or scrolling, make sure they are doing so slowly enough to enable disabled users to read and avoid any flicker.
- Do not use flashing text as this may trigger seizures.
- Keep sentences as short and simple as possible.
- Avoid using abbreviations or make sure they are written out in full the first time they are used on the screen.
- If using video clips, include captions or subtitles.
There are also physical factors to consider.
Make sure you go and check the appearance of the screen in person rather than relying on the image you see on your screen when adjusting the boards - the two may be very different.
You should also ensure that the screen is situated at a height and angle where it can also be read by users in a wheelchair.
