Abstract: An eye tracking device for tracking an eye is described. The eye tracking device comprises: a first diffractive optical element, DOE, arranged in front of the eye, an image module, wherein the image module is configured to capture an image of the eye via the first DOE. The first DOE is adapted to direct a first portion of incident light reflected from the eye, towards the image module. The eye tracking device is characterized in that the first DOE is configured to provide a lens effect.

Abstract: An augmented reality, virtual reality, or other wearable apparatus comprises an eye tracking device comprising an image sensor, a lens, and one or more processors. In some embodiments, the lens comprises a marker, and the one or more processors are configured to receive an image from the image sensor, wherein the image shows the marker, determine a distance from the image sensor to the marker based on the image, and change a calibration parameter of an eye tracking algorithm based on the distance. In some embodiments, the one or more processors are configured to receive image data from the image sensor, wherein the image data corresponds to an image as observed through the lens, determine a level or pattern of pincushion distortion in the image based on the image data, and change a calibration parameter of an eye tracking algorithm based on the level or the pattern of pincushion distortion.

Abstract: Data packets containing gaze data are streamed from an eyetracker to a client via a driver unit by receiving, repeatedly, gaze data packets in a first interface; and, providing, repeatedly, via a second interface, gaze data packets. The client sends a request message to the driver unit. The request message defines a delivery point in time in a first time frame structure at which delivery point in time in each frame of the first time frame structure the gaze data packet shall be provided to the client via the second interface. An offset is calculated between a reception point in time and the delivery point in time. The reception point in time indicates when a gaze data packet is received from the eyetracker relative to the first time structure. An adjusted data acquisition instance is assigned based on the offset. The adjusted data acquisition instance represents a modified point in time in a second time frame structure when at least one future gaze data packet shall be produced by the eyetracker. The driver unit sends a control message to the eyetracker. The control message is adapted to cause the eyetracker to produce the at least one future gaze data packet at such an adjusted acquisition instance in the second time structure that the reception point in time for the at least one future gaze data packet is expected to lie within a margin prior to the delivery point in time.

Abstract: A head mountable arrangement assists a subject to acquire spatial information about a surrounding environment by receiving gaze data from an eyetracker and spatial data from a distance sensor respectively. The gaze data describe an estimated point of regard of the subject, and the spatial data describe a distance between a reference point and an object in the surrounding environment. A feedback signal is provided, which indicates a distance from the subject to said object in the surrounding environment. The feedback signal is generated based on the estimated point of regard and the spatial data, and may reflect the distance to a surface element of an object that intersects a straight line between an eye-base line of the subject and the estimated point of regard, which surface element is located closer to the eye-base line than any other surface element of the objects in the surrounding environment along said straight line.
