Eye Tracking for Evaluating an AR-based Learning System on Monocotyledons/Dicotyledons

Abstract

Eye movement tracking and augmented reality (AR) technologies are regarded of more and more importance nowadays. Due to the continually improvement of measurement of eye movement, it is a pplied to many research areas such as the processes of reading and cognition. However, the study on eye tracking when manipulating AR systems is still in infancy. Therefore, this work aims at combing AR and eye movement evaluation. In the experiment, the p articipants were divided into two groups: domain experts group and IT skilled group, with each group 30 persons. All participants manipulated AR teaching aids on performing tasks about learning monocotyledons/dicotyledons recognition. This study used eye t racking to measure the operation of the AR task time and number of operating times. Hope to have a better understanding of the use of the AR. This study analyzed the relationship among the eye movement conditions, workload level, and the system usability v ia the use of scales through the system scale (SUS), the Task Load Index NASA -TLX scale, and several types of eye movement evaluation.
