Disappearing Computer WWW page Problems with the Internet and Access to Global Information: The Internet and its addressing structure was never really designed to be a global infrastructure and is constraining the access to resources and information. Information and databases tend to be static, and fixed to location. Difficult to group individual objects into larger objects. Difficult to add resources to the Internet (requires an ISP and a valid IP address). Search engines are not very good at gather relevant information. On the WWW, typically users get pages of irrelevant information, which just happens to have the keyword which they are searching for. Resources are gathered around local servers. Resources are tied to locations with an IP address. IP addresses are not logically organised. Infrastructure of the Internet requires complex routing.

Disappearing Computer WWW page Now: Computers use IP addresses, which require complex routing. Location of resources remain tied to networks. Movement of resources requires specialist configuration. Difficult to add objectives to the Internet. Difficult to address resources, which tend to be fixed in location. Future: Virtually every object in the world can be addressed. Resources and objects can move. Automatic tracking of resources. Easy to add objectives to the Internet, and make them usable. Objects become real and do not have a location. Internet Kitchen appliances - status - configuration - servicing Cookers - automatic control - remote monitoring of cooking Cameras - security systems - long-distance monitoring - ‘virtual’ holidays Central heating - automatic control - monitoring - automated billing - fault diagnosis Cars - real-time diagnostics - servicing monitoring - efficiency calculations - tracking systems

Disappearing Computer WWW page Conclusions on Model Regional and National Offices build large objects, such as ‘How many red cars are there in Edinburgh at this minute?’. Built-in security where homes can close their door to Regional Offices. Database becomes dynamic, where information provided is almost instant. Objects can be tracked from their birth to death. For example a box of soap powder can be tracked from the factory to the supermarket and then to the home, and finally in a dump. Easy to add to the Internet. The Internet has a simpler infrastructure. It uses a hierarchal structure rather than an attachment of autonomous units. Model is scaleable. From small scale networks to a global infrastructure. No unit is fixed in its location, thus larger objectives can be build. A large object will typically be related to information.
