EyesDecide uses a webcam to track user eye movements on the user’s computer. You don’t need any special equipment. It really works: Anyone can download and try it for themselves and see their gaze live on screen. The webcam is accessed via the HTML5 getUserMedia function, so we can use any webcam that is compatible with your web browser. Images from the camera are processed immediately on the user’s computer and then forgotten, without ever being saved. User consent is always required to turn on the webcam. We show a red icon and the camera’s activity LED to indicate when it is in use.
