Abstract: An eye tracking device includes a head-mountable frame, an optical sensor subsystem mounted to the head-mountable frame, and a processor. The optical sensor subsystem includes a set of one or more SMI sensors. The processor is configured to operate the optical sensor subsystem to cause the set of one or more SMI sensors to emit a set of one or more beams of light toward an eye of a user; to receive a set of one or more SMI signals from the set of one or more SMI sensors; and to track a movement of the eye using the set of one or more SMI signals.

Abstract: The invention relates to a method for automatically identifying at least one user of an eye tracking device (10) by means of the eye tracking device (10), wherein user identification data of the at least one user are captured by a capturing device (14) of the eye tracking device (10). Under the first condition that at least one profile (P1, P2, P3) with associated identification data (I1, I2, I3) of at least one specific user is stored in a storage medium (20), the stored identification data (I1, I2, I3) of the at least one profile (P1, P2, P3) are compared with the captured user identification data, and under the second condition that the captured user identification data match the stored identification data (I1, I2, I3) according to a predefined criterion, the at least one user is identified as the at least one specific user, for whom the at least one profile (P1, P2, P3) was stored.

Abstract: 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.

Abstract: In one implementation, an event sensor includes a plurality of pixels and an event compiler. The plurality of pixels are positioned to receive light from a scene disposed within a field of view of the event sensor. Each pixel is configured to have an operational state that is modified by control signals generated by a respective state circuit. The event compiler is configured to output a stream of pixel events. Each respective pixel event corresponds to a breach of a comparator threshold related to an intensity of incident illumination. Each control signal is generated based on feedback information that is received from an image pipeline configured to consume image data derived from the stream of pixel events.

Abstract: Various implementations disclosed herein include techniques for estimating depth using sensor data indicative of changes in light intensity. In one implementation a method includes acquiring pixel events output by an event sensor that correspond to a scene disposed within a field of view of the event sensor. Each respective pixel event is generated in response to a specific pixel sensor within a pixel array of the event sensor detecting a change in light intensity that exceeds a comparator threshold. Mapping data is generated by correlating the pixel events with multiple illumination patterns projected by an optical system towards the scene. Depth data is determined for the scene relative to a reference position based on the mapping data.

Abstract: The invention is concerned with a method for performing a calibration procedure for calibrating an eye tracking device (12), wherein a stimulus object (S) is displayed within a certain display area (22), such that the stimulus object (S) is at least temporarily moving along a defined trajectory (26) and images of at least one eye (16) of at least one user (18) are captured during the displaying of the stimulus object (S). Based on the captured images gaze data are provided and in dependency of the gaze data gaze points (P) of the at least one eye (16) of the user (18) with respect to the display area (22) are determined. Further, at least one calibration parameter (a1; a2; a3; a4; a5; a6; a7; a8; a9; a10; a11; a12; a13; a14; Θ; R; K; a; b; r) of at least one predefined calibration model (M, M1, M2, M3, M4, M5, M6) is determined in dependency of a first analysis at least of positions of at least part of the respective gaze points (P) with regard to the defined trajectory (26) of the stimulus object (S). Further, at least one control parameter (N, (A, D), T) is determined in dependency of at least part of the captured gaze data and controlling the execution of at least part of the calibration procedure in dependency of the at least one determined control parameter (N, (A, D), T).

Abstract: The invention relates to a method for operating an eye tracking device (10) for multi-user eye tracking, wherein images (24) of a predefined capturing area (14) of the eye tracking device (10) are captured by means of an imaging device (12) of the eye tracking device (10) and the captured images (24) are processed by means of a processing unit (16) of the eye tracking device (10). If a first user (26a) and a second user (26b) are present in the predefined capturing area (14) of the eye tracking device (10), a first information relating to the first user (26a) and a second information relating to the second user (26b) are determined on the basis of the captured images (24) by processing the images (24). Furthermore the images (24) are captured successively in a predeterminable time sequence.
