Patent number: 11003936Abstract: There is provided a method, system, and non-transitory computer-readable storage medium for controlling an eye tracking system to optimize eye tracking performance under different lighting conditions, by obtaining a first image captured using a camera associated with the eye tracking system, the first image comprising at least part of an iris and at least part of a pupil of an eye illuminated by an illuminator associated with the eye tracking system at a current power of illumination selected from a set of predetermined power levels; determining a contrast value between an the iris and the pupil in the image; and, if the contrast value deviates less than a preset deviation threshold value from a preset minimum contrast value, setting the current power of illumination of the illuminator to the other predetermined power level in the set of predetermined power levels.Type: GrantFiled: June 15, 2020Date of Patent: May 11, 2021Assignee: Tobii ABInventors: Viktor Åberg, Anna Redz, Niklas Ollesson, Dineshkumar Muthusamy, Magnus Ivarsson

Patent number: 10789464Abstract: At least one image registering unit records at least one series of images representing a subject. A control unit controls an operation sequence for the at least one image registering unit in such a manner that a subsequent data processing unit receives a repeating sequence of image frames there from, wherein each period contains at least one image frame of a first resolution and at least one image frame of a second resolution being different from the first resolution. Based on the registered image frames, the data processing unit produces eye/gaze tracking data with respect to the subject.Type: GrantFiled: April 9, 2019Date of Patent: September 29, 2020Assignee: Tobii ABInventors: Mattias Kuldkepp, Marten Skogo, Mattias Hanqvist, Martin Brogren, Dineshkumar Muthusamy
