Abstract
A computer based eye-tracking solution is disclosed. A computer apparatus is associated with one or more graphical displays (GUI components) that may be manipulated based on user-generated commands. An event engine is adapted to receive an eye-tracking data signal that describes a user's point of regard on the display. Based on the signal, the event engine is adapted to produce a set of non-cursor controlling event output signals, which influence the GUI-components. Each non-cursor controlling event output signal describes a particular aspect of the user's ocular activity in respect of the display. Initially, the proposed event engine receives a control signal request from each of the GUI-components. The control signal request defines a sub-set of the set of non-cursor controlling event output signals which is required by the particular GUI-component. The event engine delivers non-cursor controlling event output signals to the GUI-components in accordance with each respective control signal request.
