1. Add alternative text to images
When uploading a photo or picture into a document or website, you have the opportunity to add alternative text so that people who have a visual impairment can still understand what is happening in your presentation, website etc. When you add an image in most electronic documents, there is a "description" box. The text in this box can be read by screen reading software such as JAWS. If there is no place to add a description to the image, it is still possible to add a caption to the photo that describes what is taking place in the image.
2. Use a sans serif font and use high contrast colors
Serifs are the small extensions on the ends of some letters. A sans serif font is cleaner and crisper, and is easier to read on a digital device. You don't always have the choice to change your font. Depending on your writing platform, there may be a default font set, however, if you have a choice, choose a sans serif font, such as Veranda, for your digital documents. Try to avoid a dark backgrounds with dark text, it is difficult to read. In addition, try to include white space and headers in your documents, rather than creating a document that is an large block of text.
It is best to use tables only to display information that must be displayed in a table format, such as a bank statement. In order words, avoid using tables simply for formatting. Screen readers often present the information in tables in awkward and confusing chunks. Information that can be displayed in a simple numbered or bulleted list is preferable. When tables are necessary, be sure to include appropriate column and row heads to make the information easier to decipher.
