In addition to the scanning and reading patterns above, HCI studies try to find quantitative measures for readability. Often, these measures use try to gauge reading efficiency by using eye tracking equipment to measure the number and length of fixations that participants' eyes have as they read a text, or measure the length of time a participant needs to read a text. These studies tend to take that speed or fixation measurement and compare it to a comprehension score based on a set of questions about the text that participants answer after reading the text. The researchers use these data to create quantitative readability scores.
