Patent number: 9811155Abstract: The invention relates to a method for operating a display apparatus (12), comprising the following steps: capture of image data from at least one part of the head of a user (14) (step 110), ascertainment of at least one parameter, which the user (14) can alter by moving at least one part of the head, from the image data captured in step a) (step 120), control of a visual representation on a display apparatus (12) on the basis of the ascertained at least one parameter (step 130), wherein the capture in step a) is taken as a basis for ascertaining at least one quality parameter (step 140) and the at least one quality parameter is taken as a basis for varying at least one resolution of at least one part of the visual representation (step 150). Moreover, the invention relates to a corresponding computer program product and to a corresponding system for operating a display apparatus.Type: GrantFiled: March 27, 2015Date of Patent: November 7, 2017Assignee: SENSOMOTORIC INSTRUMENTS GESELLSCHAFT FUR INNOVATI VE SENSORIK MBHInventor: Eberhard Schmidt

Patent number: 9779300Abstract: An eye tracking method comprising: capturing image data by an image sensor; determining a region of interest as a subarea or disconnected subareas of said sensor which is to be read out from said sensor to perform an eye tracking based on the read out image data; wherein said determining said region of interest comprises: a) initially reading out only a part of the area of said sensor; b) searching the image data of said initially read out part for one or more features representing the eye position and/or the head position of a subject to be tracked; c) if said search for one or more features has been successful, determining the region of interest based on the location of the successfully searched one or more features, and d) if said search for one or more features has not been successful, reading out a further part of said sensor to perform a search for one or more features representing the eye position and/or the head position based on said further part.Type: GrantFiled: August 30, 2016Date of Patent: October 3, 2017Assignee: SENSOMOTORIC INSTRUMENTS GESELLSCHAFT FUR INNOVATIInventors: Stefan Ronnecke, Thomas Jablonski, Christian Villwock, Walter Nistico

Publication number: 20160270655Abstract: The invention relates to an eye tracking device and a method for operating an eye tracking device (30) comprising an imaging device (32), a plurality of light sources (34), a processing unit and a control unit. The imaging device (32) captures a first image (36a) while at least one of the light sources (34) emits light. If at least one first reflection (14; 16; 16a-16f) is detected, a position in the first image (36a) of the at least one first reflection (14; 16; 16a-16f) is determined, the first reflection (14; 16; 16a-16f) is categorized on the basis of the position in the first image (36a) and if the first image (36a) does not fulfil a predefined quality criterion, the plurality of light sources (34) is controlled in dependence of the categorization by changing the light intensity of at least one light source (34).Type: ApplicationFiled: December 9, 2014Publication date: September 22, 2016Applicant: SENSOMOTORIC INSTRUMENTS GESELLSCHAFT FUR INNOVATI VE SENSORIK MBHInventors: Claudio CARAFFI, Matthias NIESER, Fabian WANNER, Walter NISTICO

Publication number: 20160274659Abstract: The invention relates to a method for operating an eye tracking device (10) comprising as components an imaging device (20), an illumination unit (30) and a processing unit (40) and further at least two adjustment parameters (P A), for adjusting the components (20; 30; 40). The eye tracking device (10) comprises a control unit (42) for controlling the adjustment parameters (P A). According to the method an image (60) of an eye is captured, a condition (44) with respect to a quality related to eye tracking or a power consumption of the components (20; 30; 40) is set, a predefined correlation (42a) correlating the adjustment parameters (PA) to the quality and the power consumption is provided and the control unit (42) controls the adjustment parameters (P A) according to the predefined correlation (42a), so that the element, with respect to which the condition (44) was set, fulfils the condition (44).Type: ApplicationFiled: December 9, 2014Publication date: September 22, 2016Applicant: SENSOMOTORIC INSTRUMENTS GESELLSCHAFT FUR INNOVATI VE SENSORIK MBHInventors: Claudio CARAFFI, Matthias NIESER, Fabian WANNER, Walter NISTICO
