Abstract: A user interaction monitoring system for monitoring a user's interactions with other users in an online environment includes: an interaction monitoring unit operable to monitor interactions between a first user and at least a first group of other users in the online environment and characterising the monitored interactions, an interaction identifying unit operable to identify whether interactions between the first user and the first group of other users deviate from the interactions between a second user and a second group of other users in the online environment, and a user experience modifying unit operable to modify the user experience in the online environment for the first user if it is identified that there is a deviation in the interactions.

Abstract: A method of generating an image includes receiving a video stream, the video stream having a two-dimensional video of a three-dimensional scene captured by a video camera; determining a mapping between locations in the two-dimensional video of the scene and locations in a three-dimensional representation of the scene, the mapping being determined based on a known parameter of the video camera and a known size of a feature in the three-dimensional scene; generating a three-dimensional graphical representation of the scene based on the determined mapping; determining a virtual camera angle from which the three-dimensional graphical representation of the scene is to be viewed; rendering an image corresponding to the graphical representation of the scene viewed from the determined virtual camera angle, and outputting the rendered image for display.

Abstract: A system for generating video game inputs is provided. The system comprises an input unit operable to obtain images of a passive non-luminous object being held by a user as a video games controller. The system also comprises an object detector and object pose detector for detecting the object and its respective pose in the obtained images. The pose detector is configured to detect the pose of the object based on at least one of a (i) contour detection operation and (ii) the output of a machine learning model that has been trained to detect the poses of passive non-luminous objects in images. A user input generator is configured to generate user inputs based on the detected changes in pose of the passive non-luminous object and to transmit these to a video game unit at which a video game is being executed. A corresponding method is also provided.

Abstract: A system for displaying a virtual object includes a display device for displaying an environment; a video camera, where the video camera is operable to capture a video image of an area of a user's environment, the size of the area in the video image being larger than the size of the area of the environment viewable at the display device; a motion predictor operable to predict a motion of the camera; a scene processor operable to identify and process a portion of the captured video image that corresponds to an area of the environment that is expected to be made viewable at the display device, as a result of the predicted motion; an image generator configured to receive an input from the scene processor, and in response thereto, generate a virtual object for display at the display device; and where the image generator is configured to output the virtual object for display in response to a detection of the predicted motion.
