Identifying Bottlenecks in Student Learning Using Eye Tracking Measurements in Lathe Operation Training

This paper aims to identify bottlenecks in learning lathe operation and find ways to reduce the workload of the identification, in order to analyze effective and efficient learning processes for lathe operation training for beginner students. This paper considers bottlenecks suitable for practical training and proposes a method for measuring bottlenecks using an eye tracker to reduce the workload required for identification. Based on this method, bottlenecks during student training are identified and discussed.
