Abstract: A system has source devices (2, 4) for supplying audio and/or visual data and resource devices (6) for outputting audio and/or visual data. When a source device (2, 4) is activated, the source device connects to suitable resource device (6), by determining suitable available resource devices, for example by polling the air, and simply connecting to the suitable resource device or devices. The user can switch off unwanted resource devices and select suitable data in the event that one of the resource devices receives a plurality of data streams (18, 20).

Abstract: A portable location alarm device is provided which allows a user to preset an alarm event to occur when the device arrives at a pre-determined location. The alarm event alerts the user by audible, visual or vibrating means. The alarm device determines it's actual location using GPS data. In one embodiment the user bookmarks particular locations while physically present at a given location. Part of the bookmarking process involves the device simultaneously receiving GPS data that describes the physical location. The user can subsequently set an alarm event for any bookmarked location without the need for the device to carry large databases, for example of the type cross-referencing place names to mapping co-ordinates.

Abstract: A portable electronic device comprises augmented reality viewing apparatus for viewing a real scene and a superimposed computer generated overlay scene. In one embodiment the viewing apparatus comprises a display screen (2) and a semitransparent mirror (3). The semitransparent mirror (3) is pivotally mounted on the device and may be rotated between a position for viewing augmented reality and a position for viewing a displayed image alone. In another embodiment the real scene is viewed through a transparent display screen. When viewing augmented reality, the user aligns the overlay scene with the real scene by means of an alignment indicator (13,15, not shown in FIG. 5) in the overlay scene which corresponds to a predetermined element of the real scene.

Abstract: A memory aid device is worn by a user to provide the user with memory cues. In a preferred arrangement the apparatus captures images of people that the user encounters. A face recognition process compares the face in the captured image with faces already held in storage means which have been captured previously. On establishing a face match, the previously captured image is displayed to the user on a display in the form of a wrist worn display, a head-up display or the like. The captured images have a field of view which is such that the backdrop and any foreground objects are also included. Aspects of the previously captured image such as a familiar backdrop, foreground objects or the fact that a person is wearing summer clothes all act as visual memory cues for the user to assist them in memory recall.
