An eye-tracking system (e.g., a virtual reality or augmented realty headset) can be used for eye tracking and for iris recognition. Illuminators used to illuminate eyes of a user during eye tracking can be selectively powered on and off in connection with capturing image information in order to obtain image information that suitably depicts an iris region of an eye of the user. This image information can be used to recognize the iris region and by so doing authenticate and/or identify the user.

Iris recognition using eye-tracking system

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.

Intelligent user mode selection in an eye-tracking system

According to the invention, a method for determining what hardware components are installed on a computing device is disclosed. The method may include identifying the computing device, and determining, based on the computing device, a hardware component of the computing device. The method may also include retrieving information about the hardware component, and setting, based at least in part on the information about the hardware component, a parameter for an algorithm of software on the computing device.

Dynamic determination of hardware

A wearable device is disclosed. The wearable device may include a display, a lens, an illuminator, an image sensor, and at least one processor. The display may be configured to present images. The lens may be configured to provide a view of the display to an eye of a user. The illuminator may be configured to illuminate the eye. The image sensor may be configured to detect illumination reflected by the eye. The at least one processor may be configured to cause the display to present an image, receive data from the image sensor, determine a gaze direction of the eye based at least in part on the data from the image sensor, and cause at least one of the display or the lens to be moved until the gaze direction is directed toward the image.

Wearable device having a display, lens, illuminator, and image sensor

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, in the active mode, to use active eye illumination, which enables tracking of a corneal reflection, and to provide eye tracking data which include eye position and eye orientation; 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.

Power management in an eye-tracking system

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.

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.

Arrangement, method and computer program for controlling a computer apparatus based on eye-tracking

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.

A personal computer system includes a visual display, an imaging device adapted to provide eye-tracking data by imaging the face of a viewer of the visual display, and an input device for accepting eye-tracking control data and other input data. The imaging device is switchable between at least an active mode, a ready mode and an idle mode, 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 device for forcing the imaging device into active mode by directly triggering an interrupt; alternatively, the dedicated input device forces it permanently into idle mode.
