Abstract: A device has a content processing component operable in a content processing state, and a content transducer configured to provide augmented reality data to a user of the device based on an output of the content processing component. The device has a receiver operable to receive captured data indicative of a health condition of a user of the device. The device has a processor configured to process the captured data to identify a trigger indicative of a possible change in the health condition of a user, and in response to the trigger, modify the content processing state of the content processing component such that at least one characteristic of the augmented reality data is modified.

Abstract: An AR system includes a user interface, one or more sensors arranged to generate sensor data representing part of an environment in which a user of the AR system is located, and a memory. The memory is arranged to store object association data associating the user with one or more objects in the environment, and object location data indicating a respective location of each of the one or more objects. The AR system is arranged to determine a position of the user; determine an updated location of one of the one or more objects in dependence on the generated sensor data and the determined position of the user, update the stored object location data to indicate the determined updated location of said one of the one or more objects, and output information depending on the updated location of said one of the one or more objects via the user interface.

Abstract: An extended-reality system is described which determines extended-reality data to be obtained from the remote network-connected storage based on a location of the extended-reality system. The extended-reality system determines a communication method by which to obtain the extended-reality data, wherein the extended-reality data may be obtained by one or more requests to the remote network-connected storage or by one or more requests to a local device outside of the extended-reality system. A request is sent to at least one of the local device via a peer-to-peer network and the remote network-connected storage in dependence upon the determination by the extended-reality system.

Abstract: A head-mounted unit for assisting a user, such as a hearing-impaired user, is provided. The head-mounted unit comprises tracking sensors for monitoring a user wearing the head-mounted unit in order to determine a gaze direction which the user is looking. A sensor detects a sound source located in the identified gaze direction. Sound from the sound source may be recognised using speech recognition on captured audio from the sound source or computer vision on images of the sound source. A user interface provides information to the user to assist the user in recognising sound from the sound source.
