  • Patent number: 9829976
    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.

  • Patent number: 9791912
    Abstract: A personal computer system comprises a visual display, an imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer of the visual display, and identifying means for recognizing the viewer with reference to one of a plurality of predefined personal profiles. The personal computer system further comprises an eye-tracking processor for processing the eye-tracking data. According to the invention, the eye-tracking processor is selectively operable in one of a plurality of personalized active sub-modes associated with said personal profiles. The sub-modes may differ with regard to eye-tracking related or power-management related settings. Further, the identifying means may sense an identified viewer's actual viewing condition (e.g., use of viewing aids or wearing of garments), wherein the imaging device is further operable in a sub profile mode associated with the determined actual viewing condition.

  • Patent number: 9766699
    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.

  • Publication number: 20170249509
    Abstract: A method includes obtaining an image of an eye in a bright-pupil imaging mode in which a retinal retro-reflection complements the image of the eye in the bright-pupil mode, and obtaining an image of the eye in a dark-pupil imaging mode in which a corneo-scleral retro-reflection complements the image of the eye in the dark-pupil mode. One of the bright-pupil imaging mode and the dark-pupil imaging mode is selected based on quality of obtained images.

  • Publication number: 20170224211
    Abstract: An eye tracker comprising at least one illuminator for illuminating an eye, at least two cameras for imaging the eye and a controller is disclosed. The configuration of the reference illuminator(s) and cameras is such that, at least one camera is coaxial with a reference illuminator and at least one camera is non-coaxial with a reference illuminator. On the one hand, the controller is adapted to select one of the cameras to be active with the aim of maximising an image quality metric and avoiding obscuring objects. On the other hand, the eye tracker is operable in a dual-camera mode to improve accuracy. The invention further provides a method and computer-program product for selecting a combination of an active reference illuminator from a plurality of reference illuminators and an active camera from a plurality of cameras.

  • Publication number: 20170177079
    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).

  • Publication number: 20170090566
    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.
