Patent
Tobii AB and Sticky Inc. | Date: 2017-03-08

A method for determining a relationship between biometric data and stimuli to reach a conclusion is disclosed. The method may include associating displayed stimuli with an identity label. The method may also include collecting biometric data relative to displayed stimuli. The method may further include attributing a rating to the displayed stimuli based on the biometric data. The method may additionally include associating the rating with the identity label.

A visual display includes hidden reference illuminators adapted to emit invisible light for generating corneo-scleral reflections on an eye watching a screen surface of the display. The tracking of such reflections and the pupil center provides input to gaze tracking. A method for equipping and an LCD with a reference illuminator are also provided. Also provides are a system and method for determining a gaze point of an eye watching a visual display that includes reference illuminators. The determination of the gaze point may be based on an ellipsoidal cornea model.

According to the invention, a method for entering text into a computing device using gaze input from a user is disclosed. The method may include causing a display device to display a visual representation of a plurality of letters. The method may also include receiving gaze information identifying a movement of the users gaze on the visual representation. The method may further include recording an observation sequence of one or more observation events that occur during the movement of the users gaze on the visual representation. The method may additionally include providing the observation sequence to a decoder module. The decoder module may determine at least one word from the observation sequence representing an estimate of an intended text of the user.

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.

Tobii AB | Date: 2017-08-02

A personal computer system comprises a visual display, an imaging device adapted to provide eye-tracking data by imaging the face of a viewer of the visual display, and input means for accepting eye-tracking control data and other input data. The imaging device is switchable between at least an active mode (A), a ready mode (R) and an idle mode (I), and the switching time from the idle mode to the active mode is longer than the switching time from the ready mode to the active mode. The eye-tracking data provided in the ready mode may include eye position but not eye orientation. The system may include a dedicated input means for forcing the imaging device into active mode (A) by directly triggering an interrupt; alternatively, the dedicated input means forces it permanently into idle mode.


Patent
Tobii AB | Date: 2017-04-28

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.


Patent
Tobii AB | Date: 2017-04-05

At least one image registering unit records at least one series of images representing a subject. A control unit controls an operation sequence for the at least one image registering unit in such a manner that a subsequent data processing unit receives a repeating sequence of image frames there from, wherein each period contains at least one image frame of a first resolution and at least one image frame of a second resolution being different from the first resolution. Based on the registered image frames, the data processing unit produces eye/gaze tracking data with respect to the subject.

A computer system can be controlled with non-contact inputs through zonal control. In an embodiment, a non-contact input that is an eye-tracking device is used to track the gaze of a user. A computers display, and beyond, can be separated into a number of discrete zones according to a configuration. Each zone is associated with a computer function. The zones and/or their functions can, but need not, be indicated to the user. The user can perform the various functions by moving gaze towards the zone associated with that function and providing an activation signal of intent. The activation signal of intent can be a contact-required or non-contact action, such as a button press or dwelling gaze, respectively.


Patent
Tobii AB | Date: 2017-03-03

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).
