Abstract

We increasingly spend a vast amount of time on the Web and much of that time is spent reading. One of the main differences between reading non-Web based text and reading on the Web is the presence of hyperlinks within the text, linking various related Web content and Web pages together. Some researchers and commentators have claimed that hyperlinks hinder reading because they are a distraction that may have a negative effect on the reader's ability to process the text. However, very few controlled experiments have been conducted to verify these claims. In the experiments documented here we utilise eye tracking as a new methodology for examining how we read hyperlinked text. An eye tracker was used to observe participant's behaviour while reading. The results showed that hyperlinked text did not generally have a negative impact upon reading behaviour. However, participants did show a tendency to re-read sentences that contained hyperlinked uncommon (low frequency) words. This suggests that hyperlinks highlight important information to the reader and the hyperlinks add additional content which for more difficult concepts, invites rereading of the preceding text.
