Patent number: 11138429Abstract: 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.Type: GrantFiled: March 11, 2019Date of Patent: October 5, 2021Assignee: Tobii ABInventors: Henrik Eskilsson, Mårten Skogö

Patent number: 11042205Abstract: 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.Type: GrantFiled: October 16, 2017Date of Patent: June 22, 2021Assignee: Tobii ABInventors: John Mikael Elvesjö, Anders Kingbäck, Gunnar Troili, Mårten Skogö, Henrik Eskilsson, Peter Blixt

Patent number: 10754663Abstract: 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.Type: GrantFiled: April 23, 2018Date of Patent: August 25, 2020Assignee: Tobii ABInventor: Henrik Eskilsson

Publication number: 20200110440Abstract: 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.Type: ApplicationFiled: September 12, 2019Publication date: April 9, 2020Applicant: Tobii ABInventors: Henrik Eskilsson, Mårten Skogö

Patent number: 10203758Abstract: 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.Type: GrantFiled: August 6, 2013Date of Patent: February 12, 2019Assignee: Tobii ABInventors: Christoffer Björklund, Henrik Eskilsson, Magnus Jacobson, Mårten Skogö
