A physical object is provided that comprises a base medium, such as a paper sheet, and multiple memory tags embedded in it or attached to it. At least one of the memory tags stores location data concerning a location relationship between the object and one or more of the tags. The location data can comprise, for example, tag-location data giving the location in or on the object of the or each tag concerned, or area-of-responsibility data indicating the area of the object's surface for which the or each tag concerned has responsibility in terms of storing related data items such as print data items. Apparatus is provided for writing the location data; apparatus is also provided for subsequently using and displaying the location data particularly for facilitating access to data items stored by the tags.

An announcement method and system is provided for a collection of devices located in proximity to each other. Upon a user generating an announcement prompt, such as a hand clap, the devices knowing their relative locations, and knowing or determining the position of the user, take respective turns to make sound announcements about themselves in an order that proceeds clockwise or anticlockwise with respect to the user. Preferably, the first-to-announce device is selected such that the angle subtended at the user between the first and last-to-announce devices is minimised. In this manner, the user can more easily locate each device as it announces. The output method can be applied to any form of human-discernible output.

In order to match up individual recordings in a sequence (150) of recordings with corresponding items in a sequence (151) of separately-stored auxiliary data items concerning those recordings, both the recordings and auxiliary data are time-stamped, though from different clocks. The process of subsequently matching up the recordings and auxiliary data involves matching the pattern of timestamps.

A method is provided of setting the voice personality of a voice service site. A user browsing a voice web visits a voice site where the voice output of the site is presented using a set of voice personality characterisers with which the user is particularly comfortable. The user, in subsequently transferring to another voice service site, opts to have the voice personality that was embodied in the set of voice personality characterisers used by the site being left, transfer with the user to the new site. This transfer will typically be subject to permissions set by both the site being left and the site about to be visited.

A network-based game system includes a game processing subsystem for providing a virtual game environment in which player-controlled virtual game entities can move. Players communicate with the game processing subsystem via connectivity subsystems, such as wireless and wired LANs, that each permit access by multiple players. The processing subsystem associates each connectivity subsystem with a respective particular location in the game environment. Each particular location has at least one special game-play significance for a virtual game entity associated with a player communicating with the processing subsystem via the corresponding connectivity subsystem; for example, the game entity can only enter and leave the game at this location.

A physical object includes a base medium, such as a paper sheet, and a memory tag embedded in it or attached to it. The memory tag stores at least one measure/location data pair including a measurement of a location-dependent characteristic of the base medium originally associated with the tag, and a location in or on the object where the measurement was made. Preferably the measure/location data pair is digitally signed and stored in encrypted form. By checking whether the measure included in the stored data pair matches a current measure of the base medium at the indicated location, it is possible to check whether the base medium is the original medium. Apparatus is provided for originally writing the data pair to the memory tag; apparatus is also provided for subsequendy using the data pair for carrying out the checking operation.

A mobile device is used to effect task-related communication with a remote entity via the communications infrastructure of a wireless hotspot through which the mobile device is moving. The device includes a first estimation arrangement for estimating the time remaining before the mobile device leaves the coverage zone of the hotspot having regard to the predicted movement of the device. The device further includes a second estimation arrangement for estimating the time needed to complete the task-related communication. These two time estimates are compared with each other by a monitor unit of the device to determine whether there is sufficient time to complete the task-related communication.

Each device of a group of devices, in particular voice-controlled devices, is equipped with sound receivers and emitters and a short-range radio communication subsystem. Each device is caused to emit a test sound and, via its communications subsystem, a related timing-reference signal. Each device receiving a test sound and related timing-reference signal determines the transit time of the test sound. Using the measured transit times, the devices determine their distances one from another and, by exchanging these distances, the devices, or at least one of them, calculates the relative locations of all devices.

A user visiting a space is equipped with a mobile device in communication with a service system. Media items held by the service system are associated with various locations around the space and a user arriving at such a location is presented with the corresponding item or items. Preferably, these media items are pre-emptively loaded into a cache of the user's mobile device in dependence on the user's progress around the space. Items can also be flushed from cache on this basis. Instead of, or as a precursor to, flushing an item from cache to free up space, the cache space occupied by an item is reduced by degrading it.

A memory tag has a memory. Associated with the memory tag there is a readable structure. The readable structure can be read to generate an identifier. However, the readable structure cannot be provided so as to encode a predetermined identifier.
