    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: A method for panning content on a display of a wearable device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include determining, via a movement detection system, a head direction of the user. The method may further include, based at least in part on the gaze direction and the head direction both being consistent with a particular direction, causing content displayed on a display of the wearable device to be panned in the particular direction. The method may additionally include determining during panning of the content, via the eye tracking device, that the gaze direction of the user has returned to a neutral position. The method may moreover include, based at least in part on the gaze direction of the user returning to the neutral position, causing content displayed on the display to stop panning.

    IPC: G06F3/01

    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.

    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: 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: 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.
