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.

A method for determining a relationship between biometric data and stimuli to reach a conclusion is disclosed. The method may include associating displayed stimuli with an identity label. The method may also include collecting biometric data relative to displayed stimuli. The method may further include attributing a rating to the displayed stimuli based on the biometric data. The method may additionally include associating the rating with the identity label.

A computer system can be controlled with non-contact inputs through zonal control. In an embodiment, a non-contact input that is an eye-tracking device is used to track the gaze of a user. A computers display, and beyond, can be separated into a number of discrete zones according to a configuration. Each zone is associated with a computer function. The zones and/or their functions can, but need not, be indicated to the user. The user can perform the various functions by moving gaze towards the zone associated with that function and providing an activation signal of intent. The activation signal of intent can be a contact-required or non-contact action, such as a button press or dwelling gaze, respectively.

A computer system can be controlled with non-contact inputs, such as eye-tracking devices. A visual indicator can be presented on a display to indicate the location where a computer function will take place (e.g., a common cursor). The visual indicator can be moved to a gaze target in response to continued detection of an action (e.g., touchpad touch) by a user for a predetermined period of time. A delay between the action and the movement of the visual indicator can allow a user time to abort movement of the visual indicator. Additionally, once the visual indicator has moved, the visual indicator can be controlled with additional precision as the user moves the gaze while continuing the action (e.g., continued holding of the touchpad).

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 contains at least one image frame of a first resolution and at least one image frame of a second resolution being different from the first resolution. 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 method for entering text into a computing device using gaze input from a user is disclosed. The method may include causing a display device to display a visual representation of a plurality of letters. The method may also include receiving gaze information identifying a movement of the users gaze on the visual representation. The method may further include recording an observation sequence of one or more observation events that occur during the movement of the users gaze on the visual representation. The method may additionally include providing the observation sequence to a decoder module. The decoder module may determine at least one word from the observation sequence representing an estimate of an intended text of the user.

An eye tracker comprising at least one illuminator for illuminating an eye, at least two cameras for imaging the eye and a controller is disclosed. The configuration of the reference illuminator(s) 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. On the one hand, the controller is adapted to select one of the cameras to be active with the aim of maximising an image quality metric and avoiding obscuring objects. On the other hand, the eye tracker is operable in a dual-camera mode to improve accuracy. The invention further provides a method and computer-program product for selecting a combination of an active reference illuminator from a plurality of reference illuminators and an active camera from a plurality of cameras.

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.
