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 computer system can be controlled with non-contact inputs, such as eye-tracking devices. A computer can enlarge a portion of a display adjacent a first gaze target in response to detecting a first action (e.g., pressing a touchpad). The computer can then allow a user to position a second gaze target in the enlarged portion (e.g., by looking at the desired location) and perform a second action in order to perform a computer function at that location. The enlarging can allow a user to identify a desired location for a computer function (e.g., selecting an icon) with greater precision.

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 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.

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: 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 touch-screen 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 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.

Abstract: The invention generally relates to computer implemented systems and methods for utilizing detection of eye movements in connection with interactive graphical user interfaces and, in particular, for utilizing eye tracking data to facilitate and improve information search and presentation in connection with interactive graphical user interfaces. A gaze search index is determined based on information that has been presented on an information presentation area and gaze data signals. The gaze search index comprises links between gaze search parameters and presented information that satisfies gaze filter criteria for respective gaze search parameter. A user can initiate query searches for information on the computer device or on information hosts connectable to the computer device via networks by using combinations of gaze search parameters of the gaze search index and non gaze search parameters of a non gaze search index.
