Patent number: 11917126Abstract: An augmented reality, virtual reality, or other wearable apparatus comprises an eye tracking device comprising an image sensor, a lens, and one or more processors. In some embodiments, the lens comprises a marker, and the one or more processors are configured to receive an image from the image sensor, wherein the image shows the marker, determine a distance from the image sensor to the marker based on the image, and change a calibration parameter of an eye tracking algorithm based on the distance. In some embodiments, the one or more processors are configured to receive image data from the image sensor, wherein the image data corresponds to an image as observed through the lens, determine a level or pattern of pincushion distortion in the image based on the image data, and change a calibration parameter of an eye tracking algorithm based on the level or the pattern of pincushion distortion.Type: GrantFiled: February 24, 2023Date of Patent: February 27, 2024Assignee: Tobii ABInventors: Jonas Andersson, Anders Clausen, Richard Hainzl, Anders Kingbäck, Simon Olin, Mark Ryan, Daniel Tornéus, Björn Nutti, Torbjörn Sundberg, Catarina Tidbeck, Ralf Biedert, Niklas Blomqvist, Dennis Rådell, Robin Thunström

Patent number: 10540008Abstract: 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.Type: GrantFiled: March 31, 2016Date of Patent: January 21, 2020Assignee: Tobii ABInventors: Andreas Klingström, Mårten Skogö, Richard Hainzl, John Elvesjö

Publication number: 20180242841Abstract: A subject is illuminated whose movements of at least one eye are to be registered by an eye-tracker for producing resulting data. To this aim, a coherent light source in light producing means produces at least one well-defined light beam. A diffractive optical element is arranged between the coherent light source and an output from the light producing means. The diffractive optical element is configured to direct a light beam towards at least a first designated area estimated to cover the at least one eye of the subject. Image registering means registers light from the at least one light beam having been reflected against the subject. The resulting data is produced in response to these light reflections, which resulting data represents movements of the at least one eye of the subject.Type: ApplicationFiled: January 10, 2018Publication date: August 30, 2018Applicant: Tobii ABInventors: Richard Hainzl, Mattias Kuldkepp, Peter Blixt, Mårten Skogö
