Abstract: A 3D printing system comprises a 3D printing arrangement operable to print a 3D object, a processing unit operable to analyse images captured by an infra-red camera to detect the state of the object being printed, a substrate upon which the 3D printed object is adhered during the 3D printing process; and an infra-red light source arranged to illuminate the substrate in such a manner so as to cause total internal reflection of the infra-red light to occur in the substrate when the 3D object is not adhered to the substrate, wherein the infra-red camera is arranged to view the surface of the substrate opposite to that which the 3D object is printed upon so that the camera may capture images of the 3D object when it is correctly adhered to the substrate; and the processing unit is operable to analyses the captured images to detect whether the 3D object is correctly adhered to the substrate.

Abstract: A video server includes a video encoder to encode video data representing panoramic video content in which the panoramic video content has a greater field of view than a displayable region at a client device, the video encoder being configured to encode spatial regions within the video content at different respective encoding qualities in dependence upon track data indicating, for temporal positions with respect to the panoramic video content, a preferred viewing region within the panoramic video content at those temporal positions, so that the preferred viewing region is encoded at a higher encoding quality than another region of the panoramic video content.

Abstract: A method of evaluating a pairing between a first player and a second player of a multiplayer application comprises the steps of obtaining one or more parameter values for each of the first player and the second player, inputting the parameter values for each of the first player and the second player into an artificial neural network, obtaining at least a first pairing fitness value output from the artificial neural network, and selecting to pair the first player and the second player in dependence upon a criterion responsive to the each pairing fitness value.

Abstract: An input device for use with a processing apparatus, the input device comprising a transmitter operable to transmit user inputs to the processing apparatus, a receiver operable to receive control signalling from the processing apparatus, and a torque generating unit operable to generate torque responsive to the control signalling so as to increase the apparent mass of the input device when moved by a user.
