Smart Eye-Tracking Sensors Based on Pixel-Level Image Processing Circuits
Published in Khosla Ajit, Kim Dongsoo, Iniewski Krzysztof, Optical Imaging Devices, 2017
Smooth pursuit movements are visually guided movements in which the eye tracks a small object that is moving relative to a stationary background. The purpose of smooth pursuit movements is to stabilize the retinal image of a moving object in order to allow it to be visually examined. Pursuit movements are voluntary only in so far as we can choose to look at a moving object or ignore it. The kinematics of pursuit movements are completely determined by the motion of the object that is being tracked. It has the peak velocity of 40°/s.

Eye Tracking from a Human Factors Perspective
Published in Guy A. Boy, The Handbook of Human-Machine Interaction, 2017
Smooth pursuit eye movements are slower velocity eye movements that attempt to match the velocity of a moving target. The accuracy of smooth pursuit is given by smooth pursuit gain (eye velocity/target velocity). Perfect pursuit results in a gain of 1.0—in general normal pursuit responses have a gain slightly less than 1.0. This value decreases as target velocity increases.

In the scientific field of vision, smooth pursuit is defined as the eye continuing to track a moving object so that the image of the object can be maintained near the center of the retina, which is one of the ways that visual animals automatically shift their eyes. The characteristic of smooth pursuit is that it requires a moving stimulus to be input to the visual system. This phenomenon is difficult to create without stimulation (Kangas et al., 2016). Pursuit speeds in excess of 30 degrees per second may result in saccades. Based on these properties of smooth pursuit, it can be used as a form of eye-control interaction.

A third major type of eye movement is called smooth pursuit. Smooth pursuit allows us to continuously track a moving object and to track a stationary object while we ourselves are moving. When the head is moving, the eye movements are guided by the vestibule-ocular reflex, which utilizes information from balance organs in the head. When the head is not moving, smooth pursuit is generated based on visual information only. Smooth pursuit movements are often accompanied with corrective saccades, to keep up with the motion.
