applications. 3. 'Wireless specific broadband applications - true mobile and broadband' - This evolu- tion stream enables applications that are dependent on true real-time mobility and high bit rates. This means for instance high-quality mobile conversational multimedia with fast response times. Another example is augmented/virtual reality applications where 3D is one obvious area that is expected to take off when the technical prerequisites become generally available. Customized applications based on moving 3D pictures of high quality in the mobile communicator can be foreseen in the future. The used applications will also extend from today's hear and sight to involve all other human senses. The vast majority of applications are still to be defined. But let us try to give some short examples: 'Consultation of a medical expert on the move'. A surgeon is at the airport when con- tacted for an urgent consultancy regarding a patient. High-quality moving 3D pictures, interleaved with voice and data, transfer the necessary information for the discussion with the expert. High bit rate, i.e. more than 2 Mbps can be used and no delays are experienced during the discussion. This is an example of broadband mobile conversa- tional multimedia. 'Tourist application'. A tourist visits the Old Town in Stockholm. He puts on his AR glasses and starts the tourist application. He sees the real surroundings but additional sight information is superimposed on his glasses. His personal virtual assistant Lisa guides him when he wants. The name and history of the buildings he looks at is shown. A map with walking instructions to the 'Old Cyber Café' are shown when he thinks of (or in early version says) the name of this café. (Augmented reality (AR) mixes real and virtual realities to get relevant and continuously updated information on the surrounding environment (buildings, events etc.) when walking around.)
