EyeWorks vs iTrace

EyeWorks manages eye-tracking research from study creation through recording, analysis, and reporting. Its Design stage lets researchers script instructions, questions, images, web pages, videos, and external interfaces. Record captures eye data alongside keypresses, audio, scrolling, mouse clicks, and video for remote viewing. Analysis includes heatmaps, GazeTraces, GazeClusters, GazeStats, GazeClips, BeeSwarms, Dynamic Heatmaps, statistics, charts, graphs, and tables. Results can be exported to CSV or standard statistical analysis packages. Optional modules add cognitive workload, scene-camera recording, multi-display tracking, and face and eyelid tracking. Scene Camera supports mobile and tablet apps, physical media, objects, and real-world environments. EyeWorks is described as compatible with eye trackers from all major manufacturers, with native integration for leading simulation products and an SDK for customer software. Editions are Design, Lite, Pro, and Premier. Pricing is on request. The software supports Android and iOS; Windows Phone devices are supported through Scene Camera. EyeTracking was founded in 1999 in Solana Beach, California.

iTrace is a free, MIT-licensed toolkit for analyzing webcam eye-tracking data, with a scientific core built on NumPy and SciPy. It computes gaze in degrees of visual angle and detects fixations, saccades, and microsaccades using I-VT, I-DT, and Engbert–Kliegl methods. Pupil tools include blink detection and interpolation, preprocessing, and eye-crop segmentation measured in pixels or relative to iris size. Affine screen-space calibration reports calibration error and gaze-quality measures. The command-line tool analyzes gaze CSV files and exports JSON reports. Optional webcam capture uses OpenCV and MediaPipe, and optional interfaces include a local HTML app using FastAPI and WebSockets and a Streamlit dashboard. Live workflows can export derived gaze, pupil, and capture CSVs. By default, the workflow does not save raw eye video or persisted eye-crop images, though live viewing may send a temporary JPEG crop to a browser over a local WebSocket. The project says its checks use synthetic ground truth rather than real eye-tracking data or a reference device. Webcam pupil size is a relative proxy, not a measurement in millimetres.
