Speech Title: To Discover Novice Expert Paradigm: Sequence-Based Time-Domain and Graph-Based Frequency-Domain Analysis Method of Eye Movement
Abstract: Eye movement data can show the cognitive process in performing tasks to a certain extent. The existing researches on eye movement analysis are usually based on statistics, and it is difficult to show the correlation between the information associated within the scene. Other probabilistic algorithms usually focus on user feature recognition based on eye movement representation. However, the analysis of eye movement tends to have a coarse granularity, making it challenging to accurately discover human perception information in highly dynamic environments. In this report, the concept of timedomain and frequency-domain analysis of eye movement area of interest is proposed, within which, the frequent pattern mining method and visual cognitive graph model are constructed to mine the relationship between the areas of interest. Finally, some application examples of this model in the novice expert paradigm are presented.
