About EyeSort

EyeSort is an EEGLAB plugin that integrates text/pixel interest areas with synchronized eye-tracking events and builds robust, reproducible label codes for ERP binning. It provides a guided GUI workflow for researchers to:

• Load single or multiple EEG datasets with synchronized eye-tracking data
• Define interest areas using text-based sentences or pixel regions for reading studies
• Label fixations and saccades with rich, flexible criteria including region, pass, fixation type, and saccade direction
• Auto-generate BINLISTER Bin Descriptor Files (BDF) from labeled event codes
• Save labeled datasets for downstream ERP analysis workflows

Researchers studying reading or visual processing with co-registered eye-tracking and EEG face unique challenges in event labeling. Traditional approaches require manual coding or custom scripts that are difficult to reproduce and share.

EyeSort addresses these challenges by providing a systematic, reproducible framework for defining interest areas, identifying complex eye-movement patterns (first fixations, regressions, passes), and generating standardized event codes that integrate seamlessly with EEGLAB's ERPLAB toolbox.
