Abstract:

Scanmatch is an emerging method of eye movement data analysis in recent years. The method includes four steps: preprocessing of gaze data, division and encoding of interest regions, formation of eye track strings, and calculation of similarity scores. Researchers have used scanmatch to study the decision process theory and related influencing factors, and verified the feasibility and accuracy of scanmatch in the decision research field. Future research should use scanmatch to conduct in-depth research on various decision-making theories and influencing factors to reveal the essence of decision-making process and construct a more complete decision theory model.

Key words: eye movement, scanmatch, decision process
