User Interface Features


 Eye-tracking is an intuitive and acceptable solution to enable paralyzed patients to move a cursor across a user interface by means of their gaze, and to activate a selectable UI object after looking at it for a certain dwell time. Nevertheless, such control function of gaze can become prone to errors if the dwell time duration is too short, not customized for each specific user. Considering this issue TEEP-SLA designed the hybrid EyeBCI (eye-tracking and brain-computer interface) system to improve the performance and the usability of the gaze control through the EEG monitoring of the mental focus. Specifically, EyeBCI adapts the duration of the dwell time to the level of mental focus of the user when he/she wants to select and activate any UI item: the dwell time shortens according to the raise of the observer's concentration, improving the system precision and responsiveness.
