Abstract: When providing augmented reality display to users in an environment, two or more electronic devices operable to analyse the environment for augmented reality display purposes that are near to each other share data and/or processing relating to the analysis of the environment for augmented reality display purposes, with each device then using the data it receives from the other device when providing an augmented reality display to a user.

Abstract: Examples of the present disclosure relate to methods for processing image data. In one such example, first data representing a rendered image is received. In some cases, second data useable to identify at least one target region of the rendered image is received, the at least one target region being associated with a gaze direction of a viewer. A first portion of the first data is processed in accordance with a first data reduction rate to derive first processed data, the first portion representing the at least one target region. A second portion of the first data is processed in accordance with a second data reduction rate, different from the first data reduction rate. The second portion represents a further region of the rendered image, different from the at least one target image. At least the first processed data is outputted.

Abstract: A navigation system uses markers that are identifiable in images of an environment being navigated to determine the location of a portable device in the environment. The portable device takes images of the environment, and those images are analysed to identify markers in the images and the pose of the portable device based on the image of the marker. The identified marker and the determined pose of the portable device are then used to determine the location and orientation of the portable device in the environment being navigated.

Abstract: In a graphics processing system, a bounding volume (20) representative of the volume of all or part of a scene to be rendered is defined. Then, when rendering an at least partially transparent object (21) that is within the bounding volume (20) in the scene, a rendering pass for part or all of the object (21) is performed in which the object (21) is rendered as if it were an opaque object. In the rendering pass, for at least one sampling position (23) on a surface of the object (21), the colour to be used to represent the part of the refracted scene that will be visible through the object (21) at the sampling position (23) is determined by using a view vector (24) from a viewpoint position (25) for the scene to determine a refracted view vector (26) for the sampling position (23), determining the position 28 on the bounding volume (20) intersected by the refracted view vector (26), using the intersection position (28) to determine a vector (29) to be used to sample a graphics texture that represents the colour of the surface of the bounding volume (20) in the scene, and using the determined vector (29) to sample the graphics texture to determine a colour for the sampling position (23) to be used to represent the part of the refracted scene that will be visible through the object (21) at the sampling position (23) and any other relevant information encoded in one or more channels of the texture.

Abstract: A method of controlling an imaging system for a Head Mounted Display (HMD) device. The method comprises capturing an external scene, for example using a camera, determining an attenuation pattern, for rendering a filter area. The method also comprises determining, based on the captured external scene, a compensation pattern to for compensating at least part of the filter area, attenuating the external scene using the attenuation pattern and generating a holographic image of a virtual object, the holographic image including the compensation pattern.

Abstract: When executing a neural network comprising a sequence of plural layers of neural network processing in which at least one of the layers of the sequence of plural layers of the neural network is followed by two or more branches of neural network processing, each branch comprising a different sequence of one or more layers of neural network processing, the branch or branches to use for the neural network processing following the layer of the neural network that is followed by the two or more branches of neural network processing is selected based on a property or properties of the output feature map from the layer that is followed by the two or more branches.

Abstract: An AR system includes one or more image sensors arranged to capture image data representing a scene located within a field of view of the one or more image sensors, a display arranged to enable a user of the AR system to observe a representation or view of the scene, and an augmentation engine. The augmentation engine is arranged to process the captured image data to determine one or more visual characteristics for the captured image data and to determine, in dependence on the determined one or more visual characteristics, one or more properties for an image element to be presented on the display. The augmentation engine is arranged to present the image element, with the determined one or more properties, on the display to overlay the representation or view of the scene.

Abstract: An AR system is provided, the AR system including one or more sensors, storage, one or more communications modules, and one or more processors. The one or more sensors generate sensed data representing at least part of an environment in which the AR system is located. The one or more communications modules transmit localization data to be used in determining the location and orientation of the AR system. The one or more processors are arranged to obtain sensed data representing an environment in which the AR system is located, process the sensed data to identify a first portion of the sensed data which represents redundant information, derive localization data, wherein the localization data is derived from the sensed data and the first portion is obscured during the derivation of the localization data, and transmit at least a portion of the localization data using the one or more communication modules.

Abstract: A device comprising a first side for facing a user of the device, a second side opposite to the first side, a sensor operable to output gaze data representative of a gaze direction of the user, a display device and at least one processor. The at least one processor is configured to control the display device to control display of an image intended to be displayed on the second side of the device on the basis of the gaze data in order to reduce light being directed towards a pupil of the user from the first side of the device by the display of the image. Also described is a method of controlling such a device.

Abstract: Briefly, example methods, apparatuses, and/or articles of manufacture are disclosed that may be implemented, in whole or in part, using one or more processing devices to facilitate and/or support one or more operations and/or techniques for authenticating an identity of a subject. In particular, some embodiments are directed to techniques for authentication of an identity of a subject as being an identity of a particular unique individual based, at least in part, on involuntary responses by the subject to sensory stimuli.
