Fixation: A universal framework for experimental eye movement research✱

We propose a free and open-source framework for experimental eye movement research, whereby a researcher can record and visualize gaze data and export it for analysis using an offline web application without proprietary components or licensing restrictions. The framework is agnostic to the source of the raw gaze stream and can be used with any eye tracking platform by mapping data to a standard json-based format and streaming it in real time. We leverage web technologies to address data privacy concerns and demonstrate support for recording at 300 Hz and real-time visualization.
