Publication number: 20180307905Abstract: A method for mapping an input device to a virtual object in virtual space displayed on a display device is disclosed. The method may include determining, via an eye tracking device, a gaze direction of a user. The method may also include, based at least in part on the gaze direction being directed to a virtual object in virtual space displayed on a display device, modifying an action to be taken by one or more processors in response to receiving a first input from an input device. The method may further include, thereafter, in response to receiving the input from the input device, causing the action to occur, wherein the action correlates the first input to an interaction with the virtual object.Type: ApplicationFiled: March 20, 2018Publication date: October 25, 2018Applicant: Tobii ABInventors: Simon Gustafsson, Alexey Bezugly, Anders Kingbäck, Anders Clausen

Publication number: 20180239412Abstract: 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: ApplicationFiled: October 16, 2017Publication date: August 23, 2018Applicant: Tobii ABInventors: John Mikael Elvesjö, Anders Kingbäck, Gunnar Troili, Mårten Skogö, Henrik Eskilsson, Peter Blixt

Publication number: 20170224211Abstract: 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.Type: ApplicationFiled: April 28, 2017Publication date: August 10, 2017Inventors: Peter Blixt, Gunnar Troili, Anders Kingbäck, John Mikael Elvesjö, Mårten Skogö
