Smooth saccades
WebSaccades have longer latency from stimulus to initiation than does smooth pursuit! RHSC2 p. 76, saccadic latency Considerable variability, from 120 msec to 350 msec, mostly longer than 200 msec. "Rather this delay … Saccades are one of the fastest movements produced by the human eye (blinks may reach even higher peak velocities). The peak angular speed of the eye during a saccade reaches up to 700°/s in humans for great saccades (25° of visual angle); in some monkeys, peak speed can reach 1000°/s. Saccades to an unexpected stimulus normally take about 200 milliseconds (ms) to initiate, an…

If true, consecutive saccades that are separated only by a few samples will be joined. This avoids the situation where swing-backs at the end of longer saccades are recognized as separate saccades. Whether this works well, depends to some degree on the sampling rate of the eye-tracker. If the sampling rate is very high ...
WebSaccades refer to the eye’s ability to quickly and accurately shift from one target to another. This is a critical skill in reading, involving very specific eye movements. The eyes must move left to right along a straight line without … Webthe performance of detecting saccades or fixations, and detecting smooth pursuits (Startsev et al., 2016). We will, therefore, use the largest publicly available manually annotated eye-tracking data set that accounts for smooth pursuit to train and validate our models: GazeCom (Dorr et al., 2010; Startsev et al., 2016) (over 4 h of
