It detects the pupil from the user’s face and then tracks its movements. The purpose of this work is to design an open-source generic eye-gesture control system that can effectively track eye-movements and enable the user to perform actions mapped to specific eye movements/gestures by using computer webcam. For this purpose, we propose an imouse gesture control system which is completely operated by human eyes only.
Using this underlying information from eye movements could allow bringing the use of computers back to such patients. Through a previous research study, it was concluded that eyes are an excellent candidate for ubiquitous computing since they move anyway during interaction with computing machinery.

Actually, what helps eye tracking to determine where the user is looking is the relationship between the pupils and the flashes or reflections of infrared light, so anyone who has both eyes and can move them can use it without problems.Abstract: A high number of people, affected with neuro-locomotor disabilities or those paralyzed by injury cannot use computers for basic tasks such as sending or receiving messages, browsing the internet, watch their favorite TV show or movies. To achieve precise tracking, the sensor only needs to find the user’s pupils (and in fact it works in a similar way to how cameras eliminate the red-eye effect automatically). This is particularly beneficial for people who cannot control head movement, such as those with cerebral palsy or ALS, who may have to constantly adjust their posture.Īlso, these devices work with almost everyone and not necessarily only for people with disabilities. each time they are scanning the eyes to see where the user is looking. Thanks to the 3D human eye model combined with the user’s eye scan for better precision, these eye trackers allow you to move your head freely, meaning that you don’t have to be staring at the screen for them to work properly anymore. Not all users have eyes with the same shape and of course color, and therefore at the beginning it is necessary to calibrate the eye tracking technology so that it works in the best possible way.ĭuring calibration, the eye tracker measures how infrared light is reflected in the user’s eyes by following a point, video, or other graphic element that moves across the screen These data are combined with a 3D model of the human eye and together provide the best possible eye tracking experience.Ī breakthrough for people with disabilities A left click is performed by dwelling (stopping movement and waiting for. Eye tracking technology needs calibration By moving the eyes up/down or left/right the mouse cursor should move accordingly. It is in fact the simplest and non-intrusive way to do it, but as we have mentioned before it will depend on the capabilities of the user. Push button : if the user is able to control a push button (for example with the index finger of one hand), it can also be configured to act as a click.Dwell : the eyes are focused on a specific area for a specified time (milliseconds usually, although it is configurable), and then the system detects it and the click is performed.Blink : You can use the blink to click, but it is not the best way since doing so loses the focus of where you are looking.eViacam Only Use eViacam head tracking alone to control the mouse pointer motion, along with your chosen movement and click modes. With this we can move the mouse cursor just by looking at the area where we want, but how do you click? There are three ways to do this when using the gaze, and the method available will depend on the application being used, but also on the capabilities of the user: TrackIR Only Use TrackIR head tracking alone to control the mouse pointer, along with your chosen movement and click modes.
