According to the invention a system for authenticating a user of a device is disclosed. The system may include a first image sensor, a determination unit, and an authentication unit. The first image sensor may be for capturing at least one image of at least part of a user. The determination unit may be for determining information relating to the users eye based at least in part on at least one image captured by the first image sensor. The authentication unit may be for authenticating the user using the information relating to the users eye.

At least one image registering unit records at least one series of images representing a subject. A control unit controls an operation sequence for the at least one image registering unit in such a manner that a subsequent data processing unit receives a repeating sequence of image frames there from, wherein each period (P) contains at least one image frame of a first resolution (501) and at least one image frame of a second resolution (602) being different from the first resolution (501). Based on the registered image frames, the data processing unit produces eye/ gaze tracking data with respect to the subject.

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.

A portable device, e.g. a laptop, includes a first part (110), e.g. a base element, and a second part (120), e.g. a lid element. The second part (120) contains an optical remote sensing system (300). The second part (120) is pivotably attached to the first part (110) via a hinge means (115), such that the portable device may be arranged in an open and a closed position respectively. The optical remote sensing system (300) is configured to track at least one distinctive feature of a user of the portable device when arranged in the open position. The first and second parts (110; 120) have a respective essentially flat inner surface (111; 121), which when the portable device is arranged in the closed position are parallel and face one another. The first part (110) further includes a recess (112a) which is arranged relative to a position of the optical remote sensing system (300) such that, in the closed position, the optical remote sensing system (300) is at least partly contained in the recess (112a).

A method for determining if a users gaze is directed in the direction of a zone of interest in a 3D scene comprises: providing a 3D scene containing a zone of interest; associating a property with the zone of interest; creating a bitmap representing the location of the zone of interest in a projected view of the 3D scene, each pixel of the bitmap to which the zone of interest is projected storing the property of the zone of interest; detecting the direction of the users gaze; using the bitmap to determine if the detected users gaze is directed in the direction of the zone of interest.

A portable eye tracker device is disclosed which includes a frame, at least one optics holding member, a movement sensor, and a control unit. The frame may be a frame adapted for wearing by a user. The at least one optics holding member may include at least one illuminator configured to selectively illuminate at least a portion of at least one eye of the user, and at least one image sensor configured to capture image data representing images of at least a portion of at least one eye of the user. The movement sensor may be configured to detect movement of the frame. The control unit may be configured to control the at least one illuminator for the selective illumination of at least a portion of at least one eye of the user, receive the image data from the image sensors, and receive information from the movement sensor.
