Abstract: A method of processing a multi-view video by a client apparatus is described wherein, the multi-view video comprising a set of video streams is created by a set of cameras simultaneously capturing an object in a scene for a set of view angles and for one or more video resolutions, each video stream defining a view associated with a view angle of a camera relative to the object. The method may comprise: receiving a manifest file defining a plurality of windows for the multi-view video, a first window of the plurality of windows defining a first subset of video streams selected from the set of video streams, the first subset of video streams being associated with a first subset of view angles of the set of view angles; determining position information associated with an angular position of a viewer relative to a multi-view display apparatus, the multi-view display apparatus being configured to render the multi-view video identified in the manifest file; selecting the first window from the plurality of windows based on the position information and the first subset of view angles and requesting transmission of the first subset of video streams by a server system; and, receiving multi-view video data associated with the first subset of video streams; and, providing the multi-view video data to a decoder apparatus for decoding.

Abstract: A method performed by an electronic device for requesting tiles relating to a viewport of an ongoing omnidirectional video stream is provided. The ongoing omnidirectional video stream is provided by a server to be displayed to a user of the electronic device. The electronic device predicts (503) for an impending time period, a future head gaze of the user in relation to a current head gaze of the user, based on: A current head gaze relative to a position of shoulders of the user, a limitation of the head gaze of the user bounded by the shoulders position of the user, and a current eye gaze and eye movements of the user. The electronic device then sends (505) a request to the server. The request requests tiles relating to the viewport for the impending time period, selected based on the predicted future head gaze of the user.

Abstract: A lenticular display may be formed with convex curvature. The lenticular display may have a lenticular lens film with lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display. To enable more curvature in the display while ensuring satisfactory stereoscopic display performance, the display may have stereoscopic zones and non-stereoscopic zones. A central stereoscopic zone may be interposed between first and second non-stereoscopic zones. The non-stereoscopic zones may have more curvature than the stereoscopic zone. To prevent crosstalk within the lenticular display, a louver film may be incorporated into the display. The louver film may have a plurality of transparent portions separated by opaque walls. The opaque walls may control the emission angle of light from the display, reducing crosstalk. The louver film may be interposed between the lenticular lens film and the display panel.

Abstract: The present disclosure relates to digital solutions for eye-contact training. According to a first aspect, the disclosure relates to a computer-implemented method for eye- contact training. The method comprises presenting S1, on the one or more displays, one or more user interface objects indicative of one or more desired gaze areas representing one or more spectators of a virtual audience of the user. The method further comprises obtaining S3, using the camera, eye-gaze data indicative of the user's actual gaze direction and evaluating S4 a level of eye contact between the user and the virtual audience based on one or more rules defining a level of eye contact. The method also comprises providing S5 user feedback indicative of the evaluated level of eye-contact to the user. The disclosure also relates to an electronic user device and to a computer program configured to perform the method.

Abstract: A method (1000) for generating data suitable for determining a parameter of a human eye (H) having an eyeball (H 1 ) and an iris (H 2 ) defining a pupil (H 3 ) is presented. The method includes receiving a first image of the eye (H) for a first time (t 1 ) from a camera (14, 24) of known camera intrinsics defining an image plane (I p ), determining a first ellipse (E 1 ) in the first image, the first ellipse (E 1 ) at least substantially representing a border of the pupil (H 3 ) at the first time (t 1 ), using the first ellipse (E 1 ) to determine an orientation vector (η 1 ) of a first circle (C 1 ) and a first center line (L 1 ) on which a center of the first circle (C 1 ) is located, so that a projection of the first circle (C 1 ), in a direction parallel to the first center line (L 1 ), onto the image plane (I p ) is expected to reproduce the first ellipse (E 1 ), and determining a first eye intersecting line (D 1 ) expected to intersect a center (M) of the eyeball (H 1 ) at the first time (t 1 ) as a line which is, in the direction of the orientation vector (η 1 ), parallel-shifted to the first center line (L 1 ) by an expected distance (R) between the center (M) of the eyeball (H 1 ) and a center (P) of the pupil (H 3 )
