Online reading is harder than reading from paper. It is more difficult to read online because of the way your eyes see the message.
- Online readers are subjected to projected light which means the letters in a message are projected individually onto the screen which creates a difference in brightness levels.
- Readers viewing a paper document see reflected light. the letters on paper stand out against the background therefore the contrast range is not as high.
- Online reading only shows a horizontal rectangular view of part of a page which makes it difficult for readers to completely see what they are reading.
- Readers of a printed document can see the entire page, known as a vertical rectangle. This means readers can quickly skim the hole document.
- avoid multicolumn layouts
- reduce line length
- adjust line spacing
- divide and conquer
- be mindful of display size
- use lists to make information more visual
- indicate new paragraphs
