ead in the Big Ben example and you could be listening to an audio download of Parliamentary question time. If you wanted a 3D overview of the area for local navigation or local information reasons or a 'virtual 3D tour' of the inside of Big Ben then this could be downloaded from a server. 10.5 Mobile Metadata and Super-Phone Capabilities So there are a number of extended opportunities that are specific to the extended audio and image capture and play back/play out capabilities now being included in new-generation phones and becoming increasingly familiar to us today. Making Telecoms Work This is important because many of our mobile metadata applications do not intuitively require a connection to a network. A Nikon camera with GPS and a compass capability will know where it is and what it is looking at and could have embedded reference data available. A top of the range Nikon SLR camera, for example, has 30 000 reference images stored that are used for autoexposure, autowhite balance and autofocus SO it's a small step to add another few gigabytes of embedded reference data. The purpose of scene recognition in this example is limited to improving picture quality but the same principles can be applied to face recognition and other applications such as number-plate recognition. It is therefore important to identify functionality that can be made unique to a phone, particularly a camera phone, connected to a network. The ability to connect to the web to access smart tag or geotag information is an important differentiator but not the only one. We suggested that phones could be divided into three functional categories, standard phones that help us communicate with one another, smart phones that help us to organise our social and business lives and super phones that help us to relate to the physical world around us. Smart super phones combine all three functional domains. The mobile metadata that you get from network-connected smart super phones builds on these functional domains. We have said that smart super phones by
