An Elucidative Review on the Current Status and Prospects of Eye Tracking in Spectroscopy

This study examined how the measurement of eye activity is done using various technologies. Eye tracking (ET) is dominant and prominent. It analyzes the gazing direction of people and measures the entire functioning of the eye. In this paper, we will come to know about various technologies for eye tracking and can able to choose the best approach. Irrespective of technology, as the eye is the most affected part, we can employ this technique in all fields. The main motto of this is to demonstrate a full-fledged review of diverse topics and techniques used in eye tracking. We will be seeing some interesting techniques like skin electrodes, contact lenses, head-mounted and remote systems, and the approach behind them. Most importantly we will learn what is pupil center corneal reflection technique (PCCR). ET gives numerous application which relates to the interaction between humans and computers. This paper also incorporates various elements which took part in the selection of a particular eye-tracking method.
