摘要： A method of environment mapping comprising the steps of receiving a plurality of images from respective different viewpoints; using a simultaneous localisation and mapping ‘SLAM’ process, detect feature points in the plurality of images; classifying one or more objects within the plurality of images as being objects of interest; determining the position of the or each object of interest using feature points corresponding to the objects of interest in the images; and providing an indication of the position of one or more objects of interest to a user of a virtual display; and wherein the step of determining the position of the or each object of interest using their feature points is repeated, more frequently than for other feature points in the images.

摘要： 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.

摘要： An alert method for a head mounted display includes: identifying the current user of the head mounted display, retrieving a speaker recognition profile for the current user, detecting audio using one or more microphones, estimating whether the detected audio comprises speech corresponding to that of the current user based on the retrieved speaker recognition profile, and if not, then relaying the detected audio comprising the speech to the current user of the head mounted display.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method includes: rendering a field of view of a virtual environment for a first user of a head mounted display, rendering a view of the virtual environment outside the field of view of the first user at a lower resolution, outputting the rendered field of view for display to the first user, and recording the combined render as a video for subsequent viewing by a second user. A corresponding method includes requesting to download or stream the video from a remote source, receiving the download or stream of the video from the remote source, and outputting at least part of the stream or video for display to a second user wearing a head mounted display.

摘要： A processing device includes: a first receiving unit configured to receive one or more inputs for a video game console from a handheld video game controller using a first communication protocol; and a first transmitting unit configured to transmit the one or more inputs to the video game console using a second communication protocol, where communication using the second communication protocol has a longer range than communication using the first communication protocol.

摘要： An information processing apparatus includes: a storage unit configured to store one or more criteria associated with a video game; an executing unit configured to execute the video game; an input unit configured to receive activity data, where the activity data is data associated with physical activity of a user who is not directly playing the video game; and a processing unit configured to modify one or more aspects of a virtual environment within the executed video game when the received activity data satisfies one or more of the criteria.
