This is evidenced from a wide range of reported studies and researches. We reviewed the representative research of reading, problem-solving, teaching, affect disposition, and other issues by displaying how eye-tracking technology can support advanced studies on mental processes. In addition, basic mechanical concepts, indicators, operation methods, and data analysis for the use of eye-tracking technology were introduced and discussed.
