Gaze tracking is a concept that is used to track the movements of the eye-gaze to perform specific actions such as select, delete, create, send and so on. This concept is used in eye trackers. Currently, there are lot of research conducted to improve the reliability and accuracy of the eye trackers. Moreover, the eye trackers are mostly used for different research areas such as usability research, medical research and so on. The major application of gaze tracking technology is used in e-learning and other reasonably agree applications are with BCI, assistive technology, psychology, neuro science and gaming. However, this project identifies that eye-gaze tracking technology can be used for day-to-day activities such as email, chat and ecommerce.
This project identified that the functions of Tobii eye tracker can be divided into two major actions which are gaze awareness and gaze activatable. The gaze awareness action is mainly by performing actions from gaze positioning and the gaze movement. On the other hand, gaze activatable is performed using the gaze position combined with the keyboard press or mouse click. Moreover, this project develops a system using C# and Tobii eye tracker to perform functions such as using the gaze awareness (gaze position) to change the colour of the button, using the gaze awareness (gaze position and the delay) to click on the button to open the presence form, using the gaze awareness (gaze position) to verify whether the user is presented or not and whether the gaze tracking is on or not, using the gaze activatable (gaze position and press keyboard shift) to open more quote in the form user interface, using the gaze activatable (gaze position and press keyboard shift) to close the quote in the form user interface and using the gaze activatable (gaze position and press keyboard shift) to press the close the button.
