    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 computer apparatus is associated with a graphical display presenting at least one GUI-component adapted to be manipulated based on user-generated commands. An event engine is adapted to receive an eye-tracking data signal that describes a user's point of regard on the display. Based on the signal, the event engine produces a set of non-cursor controlling event output signals, which influence the at least one GUI-component. Each non-cursor controlling event output signal describes a particular aspect of the user's ocular activity in respect of the display. Initially, the event engine receives a control signal request from each of the at least one GUI-component. The control signal request defines a sub-set of the set of non-cursor controlling event output signals which is required by the particular GUI-component. The event engine delivers non-cursor controlling event output signals to the at least one GUI-component in accordance with each respective control signal request.

    Abstract: A control module for generating gesture based commands during user interaction with an information presentation area is provided. The control module is configured to acquire user input from a touchpad and gaze data signals from a gaze tracking module; and determine at least one user generated gesture based control command based on a user removing contact of a finger of the user with the touchpad; determine a gaze point area on the information presentation area including the user's gaze point based on at least the gaze data signals; and execute at least one user action manipulating a view presented on the graphical information presentation area based on the determined gaze point area and at least one user generated gesture based control command, wherein the user action is executed at said determined gaze point area.

    Abstract: Disclosed are various embodiments for automatic scrolling of content displayed on a display device in response to gaze detection. Content may be displayed in a window rendered on a display screen. Gaze detection components may be used to detect that a user is gazing at the displayed content and to determine a gaze point relative to the display screen. At least one applicable scroll zone relative to the display screen and a scroll action associated with each applicable scroll zone may be determined. In response to determining that the gaze point is within a first applicable scroll zone, an associated first scroll action may be initiated. The first scroll action causes the content to scroll within the window until at least one of: expiration of a defined period, determining that a portion of the content scrolls past a defined position within the window, determining that the gaze point is outside of the first scroll zone, and detecting an indicator that the user begins reading the content.

    Abstract: According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device, at least one processor, and a graphics processing device. The eye tracking device may be for determining at least one of a gaze point of a user on a display device, or a change in the gaze point of the user on the display device. The processor may be for receiving data from the eye tracking device and modifying use of at least one system resource based at least in part on the data received from the eye tracking device. The graphics processing device may be for causing an image to be displayed on the display device.

    Abstract: Circuitry of a gaze/eye tracking system obtains one or more images of a left eye and one or more images a right eye, determines a gaze direction of the left eye based on at least one obtained image of the left eye, determines a gaze direction of the right eye based on at least one obtained image of the right eye, determines a first confidence value based on the one or more obtained images of the left eye, determines a second confidence value based on the one or more obtained images of the right eye, and determines a final gaze direction based at least in part on the first confidence value and the second confidence value. The first and second confidence values represent indications of the reliability of the determined gaze directions of the left eye and the right eye, respectively. Corresponding methods and computer-readable media are also provided.

    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).
