Gaze analysis: A survey on its applications

Abstract

The examination of ocular movements has a wide range of applications due to the current developments in sensors that are now able to collect this biometric. This type of investigation is known as “gaze analysis”. The gaze has successfully examined a subject's physical and mental status in the past. As a result, over the last few decades, a large and diverse amount of literature on this subject has been generated and presented. The aim of this study is to collect and debate current gaze analysis methods based on their application field. Due to the context-specific needs for performance and efficiency, the eye movements under research are frequently evaluated from completely distinct perspectives. As a result, a collection of data, methods, and discussions ranging from the medical community to virtual and augmented reality, as well as human computer interface and remote learning, has been produced. In addition to providing a peek of novel observation on the issue of gaze analysis, the gaps between and within areas are also discussed to provide points for researchers to pursue.
