Publication number: 20230214011Abstract: Method for determining a current gaze direction of a user in relation to a three-dimensional (“3D”) scene, the 3D scene being sampled by a rendering function to produce at least one projection image of the 3D scene, wherein the method comprises the steps: determining, by a reprojection means, a reprojection transformation to be applied to the projection image before being displayed so as to be visible to the user at a gaze time point; determining, by a gaze direction detection means, a physical gaze direction of the user at said gaze time point; and determining a modified gaze direction of the user at said gaze time point, the modified gaze direction being determined in relation to the 3D scene based on both the physical gaze direction and the reprojection transformation. The disclosure also relates to a system and to a computer software function.Type: ApplicationFiled: December 23, 2022Publication date: July 6, 2023Inventor: Denny Rönngren

Patent number: 11327313Abstract: The present disclosure relates to a method for displaying an image with a specific depth of field. The method comprises the steps of obtaining information data related to a focal distance adapted to a user gazing at a display, determining a pupil size of said user, estimating a depth of field of said user's eyes based on said focal distance and said pupil size, and rendering an image based on said depth of field to be displayed on said display. Further, the present disclosure relates to a system, a head-mounted display and a non-transitory computer readable medium.Type: GrantFiled: March 30, 2020Date of Patent: May 10, 2022Assignee: Tobii ABInventor: Denny Rönngren

Publication number: 20210089121Abstract: Systems and methods for gaze origin selection based on dominant eye shift of a user. Systems and methods described herein include eye tracking devices and computing devices. The first eye is initially set as the dominant eye. A first gaze ray for the first eye and a second gaze ray for a second eye are determined by an eye tracking system. The first gaze ray intersects a first object and the second gaze ray intersects a second object within the field of view, at a first depth and a second depth respectively. A convergence depth of the first gaze ray and the second gaze ray is determined and compared against the first depth and the second depth. When a second offset between the second depth and the convergence depth is smaller than a first offset between the first depth and the convergence depth, the second eye is set as the dominant eye.Type: ApplicationFiled: September 23, 2019Publication date: March 25, 2021Applicant: Tobii ABInventor: Denny Rönngren

Patent number: 10686972Abstract: A method for rotating a field of view represented by a displayed image is disclosed. The method may include displaying a first image representing a first field of view. The method may also include determining a gaze direction of a user toward the first image. The method may further include identifying a subject in the first image at which the gaze direction is directed, wherein the subject is in a first direction from a center of the first image. The method may further include receiving a directional input in a second direction. The method may additionally include, based at least in part on the second direction being substantially the same as the first direction, displaying a second image representing a second field of view, wherein the subject is centered in the second image.Type: GrantFiled: March 30, 2018Date of Patent: June 16, 2020Assignee: Tobii ABInventor: Denny Rönngren

Patent number: 10460527Abstract: Disclosed herein is a system comprising a display, at least one imaging device for capturing at least one user image of at least part of the user, a determination unit connected to the at least one imaging device, said determination unit being used for determining information relating to the user's eye based on the at least one user image. The system further comprises a scene renderer connected to the display and the determination unit, the scene renderer being used to generate a first image on the display, whereby the scene renderer is configured to generate at least a partially modified image relative to the first image in real time, without the user noticing, based on the information relating to the user's eye.Type: GrantFiled: June 30, 2017Date of Patent: October 29, 2019Assignee: Tobii ABInventor: Denny Rönngren

Publication number: 20190138091Abstract: According to the invention, a system for presenting graphics on a display device is disclosed. The system may include an eye tracking device for determining a gaze point of a user on a display device. The system may also include a graphics processing device for causing graphics to be displayed on the display device. The graphics displayed on the display device may be modified such that the graphics in an area including the gaze point of the user have at least one modified parameter relative to graphics outside the area. The size of the area may be based at least in part on an amount of noise in the gaze point over time and at least one other secondary factor.Type: ApplicationFiled: September 17, 2018Publication date: May 9, 2019Applicant: Tobii ABInventors: Robin Thunström, Denny Rönngren, Anders Clausen
