Webcam eye-tracking is an innovative method that predicts a person's gaze point.We use the computing power of regular PC/laptop to run AI (Deep neural network) that analyzes images coming from a webcam. The AI detects a panelist's face, pupils and predicts a gaze point.All of this is performed entirely in a web browser in real-time. Thanks to this, panelists do not have to worry about their privacy. We do not send any image or sound to our servers. We only store the gaze point predictions from our AI, in the form of basic text data similar to "Timestamp: 10, GazePointX: 200, GazePointY: 330".
