PyeLink and SyeLink are two complementary open-source Python tools for running eye-tracking experiments and parsing data from SR Research Ltd. EyeLink hardware. PyeLink simplifies experiment creation with plug-and-play support for multiple display backends (Pygame, PsychoPy, Pyglet) and enables two features not available in existing tools: recording data during calibration and validation phases, and simultaneously recording raw pupil/corneal-reflection data alongside calibrated gaze data. SyeLink processes the resulting enriched ASC files into structured JSON and CSV formats through both a Python API and a command-line interface, with built-in visualization of calibration and validation results.
