pEYES is a Python package that enables researchers to perform robust, quantitative comparisons of eye-tracking segmentation algorithms. It provides implementations of several widely used algorithms and allows users to evaluate their performance against ground-truth, human-annotated datasets. The package simplifies the process of selecting an optimal algorithm by offering over 20 metrics to quantify performance, enhancing analysis reliability and reproducibility.
pEYES offers several core functionalities designed to facilitate the processing, analysis, and comparison of eye-tracking data:
- Downloading & Parsing Datasets: Provides functions to easily download and parse publicly available, human-annotated eye-tracking datasets, streamlining the setup process for benchmarking algorithms.
- Configuring & Running Detection Algorithms: Allows users to configure various eye-tracking segmentation algorithms and apply them to either the built-in datasets or their own custom data.
- Algorithm Comparison & Analysis: Offers tools to analyze the results of detection algorithms, compare their performance against human-annotated ground-truth data, or evaluate differences between multiple algorithms.
- Visualization Tools: Includes visualization capabilities, such as generating fixation heatmaps and saccade trajectories, to help users intuitively interpret the results of different detection algorithms.
This functionality makes pEYES a versatile tool for researchers aiming to enhance the accuracy and reliability of their eye-tracking data analysis.
This package has been created and tested with python 3.12.
