A SYSTEMATIC REVIEW ON THE METHODOLOGY OF EYE TRACKING - UNDERSTANDING THE SAMPLING DESIGN

Abstract
Recognizing the expanding applications of eye-tracking technology across various fields, the paper examines its effectiveness through a comprehensive review of existing studies. This paper aims to assist researchers in harnessing the vast capabilities of eye-tracking technologies and employing the right size of the sample. Systematically reviewing extant research in the different domains with respect to the fundamentals and practices of eye-tracking methodology, this paper presents a concise, empirical eye-tracking demonstration. The paper explores eye-tracking applications in domains such as communication science, programming and code comprehension, tourism research, consumer behavior in food choices, marketing research and online consumer behavior, industrial applications, social media marketing and online customer behavior, media consumption and human-computer interaction. The revealed data are based on the relevant studies of eye tracking usability. Additionally, we highlight the main problems and challenges, identify existing research gaps, and suggest directions for future studies. These contributions suggest future outlooks for how to incorporate optimal samples within eye-tracking methodology. Keywords - Eye Tracking, Sample, Eye Tracking Methodology
