Arrangement, method and computer program for controlling a computer apparatus based on eye-tracking

Abstract

A computer apparatus is associated with a graphical display presenting at least one GUI-component adapted to 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 produces a set of non-cursor controlling event output signals, which influence the at least one GUI-component. Each non-cursor controlling event output signal describes a particular aspect of the user's ocular activity in respect of the display. Initially, the event engine receives a control signal request from each of the at least one GUI-component. 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 at least one GUI-component in accordance with each respective control signal request.

What is claimed is: 
     
         1 . An arrangement for controlling a computer apparatus associated with a graphical display, the display displaying a representation of at least one GUI-component, the arrangement comprising:
 an event engine configured to receive an eye-tracking data signal describing a user's point of regard on the display, and configured to influence the representation of the at least one GUI-component at least based on the eye-tracking data signal,   wherein upon the user's point of regard remaining fixated within bounds of the representation of the at least one GUI-component for a predetermined period of time, the event engine influences the computer apparatus to expand the at least one GUI-component such that more information than was initially visible in the at least one GUI-component is displayed.
