摘要： The present invention relates to control of a computer system, which includes a data processing unit, a display and an eye tracker adapted to register a user's gaze point with respect to the display. The data processing unit is adapted to present graphical information on the display, which includes feedback data reflecting the user's commands entered into the unit. The data processing unit is adapted to present the feedback data such that during an initial phase, the feedback data is generated based on an absolute position of the gaze point. An imaging device of the system is also adapted to register image data representing movements of a body part of the user, and to forward a representation of the image data to the data processing unit. Hence, during a phase subsequent to the initial phase, the data is instead generated based on the image data.

摘要： An eye/gaze tracker with first and second light sources each configured to illuminate an eye of a subject and controlled to selectively emit light towards the eye in such a manner that within an operation sequence the eye is illuminated by the first light source during at least one first interval and by the second light source during at least one second interval. An image sensor has a plurality of photodiodes each of which is associated with first and second charge storages configured to store electric charges based on an amount of light reaching the photodiode. At least one switch of the image sensor is controlled such that the electric charges are stored in the first charge storage as a result of the illumination during the at least one first interval and in the second charge storage as a result of the illumination during the at least one second interval.

摘要： An eye tracker includes at least one illuminator for illuminating an eye, at least two cameras for imaging the eye and a controller. The configuration of the reference illuminator and cameras is such that, at least one camera is coaxial with a reference illuminator and at least one camera is non-coaxial with a reference illuminator. The controller selects one of the cameras to be active to increase an image quality metric and avoid obscuring objects. The eye tracker is operable in a dual-camera mode to improve accuracy.

摘要： 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.
