Patent number: 10664051Abstract: A graphics presentation apparatus including a display unit, an eye-tracking module, and a data output module. The eye-tracking module registers image data representing at least one eye of a user of the apparatus. Furthermore, the eye-tracking module determines, based on the registered image data, an orientation of the at least one eye relative to the display unit. Finally, in response thereto, the eye-tracking module generates a control signal controlling the data output module to produce visual content with such orientation on the display unit that a misalignment between the orientation of said at least one part and the orientation of the at least one eye of the user is minimized.Type: GrantFiled: October 26, 2018Date of Patent: May 26, 2020Assignee: Tobii ABInventors: Aron Yu, Marten Skogo, Robert Gavelin, Per Nystedt

Patent number: 10635900Abstract: A method of presenting gaze-point data of a subject detected by an eye-tracking unit includes presenting a test scene picture acquired by a camera unit, and displaying shapes on the test scene picture. The shapes represent momentary gaze points of the subject.Type: GrantFiled: October 2, 2017Date of Patent: April 28, 2020Assignee: Tobii ABInventors: Johan Strombom, Marten Skogo, Per Nystedt, Simon Gustafsson, John Mikael Holtz Elvesjo, Peter Blixt

Patent number: 9495589Abstract: A gaze-point detection system includes at least one infrared (IR) signal source to be placed in a test scene as a reference point, a pair of eye glasses to be worn by a person, and a data processing and storage unit for calculating a gaze point of the person wearing the pair of eye glasses. The pair of eye glasses includes an image sensor, an eye-tracking unit and a camera. The image sensor detects IR signals from the at least one IR signal source and generates an IR signal source tracking signal. The eye-tracking unit determines adapted to determine the gaze direction of the person and generates an eye-tracking signal, and the camera acquires a test scene picture. The data processing and storage unit communicates with the pair of eye glasses and calculates the gaze point relative to the test scene picture.Type: GrantFiled: January 26, 2009Date of Patent: November 15, 2016Assignee: TOBII ABInventors: Johan Strombom, Marten Skogo, Per Nystedt, Simon Gustafsson, John Mikael Holtz Elvesjö, Peter Blixt
