Abstract: A data processing unit generates graphics data that are sent to a display screen of a head-mountable structure worn by a user. Thereby, the user can observe the image data, which reflect a virtual reality environment implemented by the data processing unit, namely image data representing a field of view as seen by the user from a particular position and in a particular direction in the virtual reality environment. The head-mountable structure includes a first light source projecting a well-defined light pattern on a light-reflecting surface. The data processing unit is associated with an image registering unit recording image data representing the first well-defined light pattern. The data processing unit calculates the graphics data based on the image data.

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: There is provided methods, systems and computer program products for identifying an interaction element from one or more interaction elements present in a user interface, comprising: receiving gaze information from an eye tracking system; determining the likelihood that an interaction element is the subject of the gaze information from the eye tracking system; and identifying an interaction element from the one or more interaction elements based on said likelihood determination.

Abstract: An imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer, wherein: the imaging device is switchable between at least an active mode and a ready mode; the imaging device is configured, in the active mode, to use active eye illumination, which enables tracking of a corneal reflection, and to provide eye tracking data which include eye position and eye orientation; and the imaging device is configured, in the ready mode, to reduce an illumination intensity from a value the illumination intensity has in the active mode.

Abstract: An image sensing apparatus has a light sensitive area and a control unit. The light sensitive area registers image data in response to an incoming amount of light, and is operable in an active mode wherein image data can be read out there from as well as in a standby mode wherein image data cannot be read out. The control unit produces a control signal setting the light sensitive area to operate in the active mode and the standby mode respectively in a cyclic manner during an operation period, which preferably encompasses multiple data frame read-outs of image data from the light sensitive area.

Abstract: 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.

Abstract: A visual display includes hidden reference illuminators adapted to emit invisible light for generating corneo-scleral reflections on an eye watching a screen surface of the display. The tracking of such reflections and the pupil center provides input to gaze tracking. A method for equipping and an LCD with a reference illuminator are also provided. Also provides are a system and method for determining a gaze point of an eye watching a visual display that includes reference illuminators. The determination of the gaze point may be based on an ellipsoidal cornea model.

Abstract: 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).
