ECTtracker is an eye-tracking AAC (Alternative and Augmentative Communication) program allowing the real-time analysis of the users 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 users 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 users eyes: on some samples the users 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.ECTtracker is fully customizable. The program contains more than 45 settings with which you can change the appearance and functionality. The user has a full control over the video processing speed (frames per second). Some settings can significantly reduce the requirements for computer resources so the program runs stably even on low-end computers.ECTtracker doesnt require installation or modifying the registry of the operating system and works with portable devices. Supports simultaneous launch of multiple copies of the program Possibility to save all table samples and user settings in separate files.
