Overview
EyeLink
EyeLink offers a comprehensive suite of eye-tracking solutions that help you capture and analyze human gaze behavior with extreme precision. Whether you are conducting cognitive psychology experiments, clinical trials, or usability studies, you can rely on high-frequency sampling rates to catch even the smallest eye movements. The platform combines robust hardware with sophisticated software to ensure your data remains accurate across diverse participant groups and lighting conditions.
You can manage the entire research lifecycle within the EyeLink ecosystem, from initial experiment design to complex data visualization. The software allows you to create interactive stimuli, record synchronized behavioral data, and export cleaned datasets for statistical analysis. It is built specifically for researchers and clinicians who require millisecond-level accuracy and reliable technical support for high-stakes data collection.
RealEye
RealEye is a cloud-based platform that turns any standard webcam into a high-precision eye-tracking tool. You can conduct remote user research without expensive hardware, allowing you to see exactly where your participants look while they interact with your designs, videos, or live websites. By leveraging AI and computer vision, the software tracks gaze points and facial expressions to provide deep insights into human behavior and attention.
You can easily recruit participants from a global panel or invite your own users to join a study via a simple browser link. The platform generates instant visual reports, including heatmaps and AOI (Area of Interest) statistics, helping you identify which elements capture attention and which are ignored. It is an ideal solution for UX designers, marketers, and academic researchers who need fast, scalable, and cost-effective eye-tracking data to validate their visual content.
Overview
