Patent number: 9791912Abstract: 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 26, 2012Date of Patent: October 17, 2017Assignee: Tobii ABInventors: John Mikael Elvesjö, Anders Kingbäck, Gunnar Troili, Mårten Skogö, Henrik Eskilsson, Peter Blixt

Patent number: 8976110Abstract: 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.Type: GrantFiled: October 27, 2011Date of Patent: March 10, 2015Assignee: Tobii Technology ABInventors: Henrik Eskilsson, Mårten Skogö, John Elvesjö, Peter Blixt

Publication number: 20140009390Abstract: 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: ApplicationFiled: August 6, 2013Publication date: January 9, 2014Applicant: Tobii Technology ABInventors: Christoffer BJÖRKLUND, Henrik ESKILSSON, Magnus JACOBSON, Mårten SKOGÖ
