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).

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 to use active eye illumination in the active mode, which enables tracking of a corneal reflection; 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, and to provide eye-tracking data which include eye position but not eye orientation.

Abstract: A method and system for assisting a user when interacting with a graphical user interface combines gaze based input with gesture based user commands. A user of a computer system without a traditional touch-screen can interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. A solution for touch-screen like interaction uses gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen. Combined gaze and gesture based interaction with graphical user interfaces can be used to achieve a touchscreen like environment in computer systems without a traditional touchscreen or in computer systems having a touchscreen arranged ergonomically unfavorable for the user or a touchscreen arranged such that it is more comfortable for the user to use gesture and gaze for the interaction than the touchscreen.

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: The present invention provides improved methods and systems for assisting a user when interacting with a graphical user interface by combining gaze based input with gesture based user commands. The present invention provide systems, devices and method that enable a user of a computer system without a traditional touch-screen to interact with graphical user interfaces in a touch-screen like manner using a combination of gaze based input and gesture based user commands. Furthermore, the present invention offers a solution for touch-screen like interaction using gaze input and gesture based input as a complement or an alternative to touch-screen interactions with a computer device having a touch-screen, such as for instance in situations where interaction with the regular touch-screen is cumbersome or ergonomically challenging. Further, the present invention provides systems, devices and methods for combined gaze and gesture based interaction with graphical user interfaces to achieve a touchscreen like environment in computer systems without a traditional touchscreen or in computer systems having a touchscreen arranged ergonomically unfavourable for the user or a touchscreen arranged such that it is more comfortable for the user to use gesture and gaze for the interaction than the touchscreen.

Abstract: An eye-tracking system (e.g., a virtual reality or augmented realty headset) can be used for eye tracking and for iris recognition. Illuminators used to illuminate eyes of a user during eye tracking can be selectively powered on and off in connection with capturing image information in order to obtain image information that suitably depicts an iris region of an eye of the user. This image information can be used to recognize the iris region and by so doing authenticate and/or identify the user.

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 gaze tracking system, leaving a low power mode in response to an activation signal, initial burst of eye pictures in short time by restricting the image area of a sensor, purpose of enabling an increased frame rate. Subsequent eye pictures are captured at le rate. The first gaze point value is computed memorylessly based on the initial burst res and no additional imagery, while subsequent values may be computed recursively to account previous gaze point values or information from previous eye pictures. The restriction of the image area may be guided by a preliminary overview picture captured using the different sensor. From the gaze point values, the system may derive a control signal to a computer device with a visual display.

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.
