    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: A method for determining correspondence between a gaze direction and an environment around a wearable device is disclosed. The wearable device may include an eye tracking device and an outward facing image sensor. The method may include receiving an input parameter and at least one scene image from the outward facing image sensor. The method may further include determining, with at least the eye tracking device, at least one gaze direction of a wearer of the wearable device at a point in time corresponding to when the scene image was captured by the outward facing image sensor. The method may additionally include determining, based at least in part on the input parameter, that a particular scene image includes at least a portion of a predefined image. The method may moreover include determining, based on the at least one gaze direction, at least one gaze point on the particular scene image.

    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: 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 content and to determine a gaze point. At least one scroll zone relative to the display screen and a scroll action associated with each scroll zone may be determined. In response to determining that the gaze point is within a scroll zone, an associated scroll action may be initiated. The 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 scroll zone, and detecting an indicator that the user begins reading the content.

    Abstract: A gaze tracking system, leaving a low power mode in response to an activation signal, captures an initial burst of eye pictures in short time by restricting the image area of a sensor, with the purpose of enabling an increased frame rate. Subsequent eye pictures are captured at normal frame rate. The first gaze point value is computed memorylessly based on the initial burst of eye pictures and no additional imagery, while subsequent values may be computed recursively by taking into 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 same or a different sensor. From the gaze point values, the system may derive a control signal to be supplied to a computer device with a visual display.
