    Abstract: Head pose information may be determined using information describing a fixed gaze and image data corresponding to a user's eyes. The head pose information may be determined in a manner that is disregards facial features with the exception of the user's eyes. The head pose information may be useable to interact with a user device.

    Abstract: According to the invention, a system for tracking a gaze of a user across a multi-display arrangement is disclosed. The system may include a first display, a first eye tracking device, a second display, a second eye tracking device, and a processor. The first eye tracking device may be configured to determine a user's gaze direction while the user is gazing at the first display. The second eye tracking device may be configured to determine the user's gaze direction while the user is gazing at the second display. The processor may be configured to determine that the user's gaze has moved away from the first display in a direction of the second display, and in response to determining that the user's gaze has moved away from the first display in the direction of the second display, deactivate the first eye tracking device, and activate the second eye tracking device.

    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.

    Abstract: A method for determining correspondence between a gaze direction and an environment around a wearable device is disclosed. The wearable device may include an eye tracking device and an outward facing image sensor. The method may include receiving an input parameter and at least one scene image from the outward facing image sensor. The method may further include determining, with at least the eye tracking device, at least one gaze direction of a wearer of the wearable device at a point in time corresponding to when the scene image was captured by the outward facing image sensor. The method may additionally include determining, based at least in part on the input parameter, that a particular scene image includes at least a portion of a predefined image. The method may moreover include determining, based on the at least one gaze direction, at least one gaze point on the particular scene image.

    Abstract: A personal computer system comprises a visual display, an imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer of the visual display, and identifying means for recognizing the viewer with reference to one of a plurality of predefined personal profiles. The personal computer system further comprises an eye-tracking processor for processing the eye-tracking data. According to the invention, the eye-tracking processor is selectively operable in one of a plurality of personalized active sub-modes associated with said personal profiles. The sub-modes may differ with regard to eye-tracking related or power-management related settings. Further, the identifying means may sense an identified viewer's actual viewing condition (e.g., use of viewing aids or wearing of garments), wherein the imaging device is further operable in a sub profile mode associated with the determined actual viewing condition.

    Abstract: According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device, at least one processor, and a graphics processing device. The eye tracking device may be for determining at least one of a gaze point of a user on a display device, or a change in the gaze point of the user on the display device. The processor may be for receiving data from the eye tracking device and modifying use of at least one system resource based at least in part on the data received from the eye tracking device. The graphics processing device may be for causing an image to be displayed on the display device.
