Abstract: Techniques for reducing a read out time and power consumption of an image sensor used for eye tracking are described. In an example, a position of an eye element in an active area of a sensor is determined. The eye element can be any of an eye, a pupil of the eye, an iris of the eye, or a glint at the eye. A region of interest (ROI) around the position of the eye is defined. The image sensor reads out pixels confined to the ROI, thereby generating an ROI image that shows the eye element.

Abstract: A subject is illuminated whose movements of at least one eye are to be registered by an eye-tracker for producing resulting data. To this aim, a coherent light source in light producing means produces at least one well-defined light beam. A diffractive optical element is arranged between the coherent light source and an output from the light producing means. The diffractive optical element is configured to direct a light beam towards at least a first designated area estimated to cover the at least one eye of the subject. Image registering means registers light from the at least one light beam having been reflected against the subject. The resulting data is produced in response to these light reflections, which resulting data represents movements of the at least one eye of the subject.

Abstract: According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device and a graphics processing device. The eye tracking device may be for determining a gaze point of a user on a display device. The graphics processing device may be for causing graphics to be displayed on the display device. The graphics displayed on the display device may be modified such that the graphics are of higher quality in an area including the gaze point of the user, than outside the area.

Abstract: A portable computing device is disclosed which may include a base element, a lid element, a first motion sensor, a second motion sensor, a processor, and an eye tracking system. The first motion sensor may be disposed in the base element. The second motion sensor may be disposed in the lid element. The processor may be configured to control the first motion sensor to detect first motion information, control the second motion sensor to detect second motion information; and determine final motion information based at least in part on the first motion information and the second motion information. The eye tracking system may be configured to determine a gaze position of a user based at least in part on the final motion information, wherein the processor is further configured to execute one or more control processes based at least in part on the determined gaze position meeting a predetermined condition.

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.
