EyeWorks vs PyGaze

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.

PyGaze is an open-source Python toolbox for running eye-tracking experiments. It provides a shared interface for stimulus presentation and tracker communication, with support for EyeLink, SMI, Tobii, and mouse-simulated tracking. For stimuli, it works with PsychoPy and PyGame. The EyeTracker interface covers calibration, recording, gaze sampling, pupil-size retrieval, and fixation and saccade event functions. Gaze-contingent tools include forced retinal location, a cursor that follows gaze, and areas of interest. PyGaze is free at free and supports Linux, macOS, and Windows. Downloads include pip installation instructions for those systems, source packages, and portable Windows environments. The about page recommends Python 2.X and describes its audience as people with minor to advanced programming skills. Some tracker connections require separate steps: PyLink is proprietary and requires registration with SR Research, while SMI and Tobii API downloads must be requested from their makers. PyGaze supplies fresh gaze samples at the tracker’s sampling rate and returns the newest available sample between fresh samples.
