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
