pymovements 0.26.2

A python package for processing eye movement data

---

pymovements is an open-source python package for processing eye movement data. It provides a simple interface to download publicly available datasets, preprocess gaze data, detect oculomotoric events and render plots to visually analyze your results.

Getting Started

If you are new to pymovements or to eye-tracking data analysis, we recommend starting with the User Guide, which introduces the concepts, data structures, and workflows used throughout the library: 👉 :doc:user-guide/index

Quick example

For a minimal example of loading and processing eye-tracking data with pymovements:

import pymovements as pm

dataset = pm.Dataset(
    'JuDo1000',  # choose a public dataset from our dataset library
    path='data/judo100',  # setup your local dataset path
)
dataset.download()  # download a public dataset from our dataset library
dataset.load()  # load the dataset

Transform coordinates and calculate velocities:

dataset.pix2deg()  # transform pixel coordinates to degrees of visual angle
dataset.pos2vel()  # transform positional data to velocity data

Detect oculomotoric events:

dataset.detect('ivt')  # detect fixation using the I-VT algorithm
dataset.detect('microsaccades')  # detect saccades using the microsaccades algorithm
