Microsaccade Analysis using MS_Toolbox_R (Engbert et al, 2015)
Delivered - 31 March 2020, 9am EST

The online saccade parser implemented in the EyeLink Host Software is not designed to detect microsaccades (e.g. saccades < ~1 degree of visual angle). If you want to detect microsaccades in your EyeLink data, you will need to use an alternative technique, such as the widely adopted approach described by Engbert and Kleigl in their 2003 paper.

The modified R code, can be downloaded from the thread linked below, which also contains some instructions. This webinar will provide a practical demonstration of how to use the Microsaccade Toolbox for R (Engbert et al, 2015) to detect microsaccades in EyeLink data. The topics covered will include:
  • Intro to Microsaccades
  • EyeLink Host Software (Online Saccade Parser and Heuristic Filter)
  • MS_Toolbox_R Overview
  • Walkthrough of demo.R Script
  • Walkthrough of the Core R Scripts
  • How to Format and Extract Pupil Data With Data Viewer
  • Walkthrough of the EyeLink_Demo.R Wrapper Script
