Abstract
A method for visual interaction between a user (10) and a machine (20) using gaze estimation is disclosed. The method comprises: displaying an initial element and one or more further elements on a display (30), each further element being spatially separated from the initial element, whereby each further element defines an angular range with respect to the position of the initial element; determining that a direction from a first gaze point to a second gaze point lies within the angular range defined by a further element selected by the user; and sending instructions to the machine to perform a function associated with the selected element. A system (1) for visual interaction between a user (10) and a machine (20) using gaze estimation is also disclosed. The gaze points of the user may be determined with relatively low precision.
