ECTtracker is an eye-tracking program, allowing the real-time analysis of the user's eye (open or closed). This application is a part of the complex of assistive technology software created by EyeComTec (LAZgroup SA). ECTtracker implements low cost computer mediated communication for people suffering from various forms of paralysis or significantly impaired mobility.

The program is used in conjunction with applications for capturing video from webcams or other devices connected to your computer (ex: ECTcamera, Skype). The program assigns different key codes to different states of the user's eye, which can later be transmitted to any application (ex: ECTmorse, ECTkeyboard). Thus, by opening and closing one or both eyes, the user can control programs and type texts.

Using a special recognition structure ECTtracker compares the image received in real-time from the camera with pre-stored user samples. Samples are small static images with accurate focus on the area of the user's eyes: on some samples the user's eyes are open, on other - one or both eyes are closed. The program selects the samples with the highest match through comparing the image samples obtained with the camera.
