Pervasive Computing In the 19th Century, James Watt changed the world. The steam engine – extended the power and strength of workers. Centralised energy Other inventions changed this centralised view of energy Von Siemens dynamo in 1866 Edison – power plant in 1882 Diesel – engine in 1892 November 18 Pervasive Computing

Pervasive Computing Energy became decentralised. Could provide energy anywhere at anytime. The ubiquituous availability of energy changed lifestyles. Mass production, reduced costs, raised wages. More applications spread to homes – fridges, tv, lawn mowers November 18 Pervasive Computing

Pervasive Computing Applications are distinguished by Convenience Usability for a specific purpose Hiding the technology The applications changed the world, NOT the technology by itself. November 18 Pervasive Computing

Pervasive Computing In the 20th century – computers arrived. Mental capabilities are multiplied. Process larger amounts of information, bills, payrolls, invoices and other data. Computers began as room filling and mysterious black boxes. Centralised, tightly controlled systems Closed shop IT concentrated on a static environment for users. November 18 Pervasive Computing

Pervasive Computing Similar to the Industrial Revolution Move from centralised to a more pervasive or decentralised computing environment. The PC has conquered Computing is intrinsic to Entertainment, commerce, telecommunication, finance, industry We have a high tech culture relying on electronic creation, storage and transmission of personal and business information.

Pervasive Computing Intelligent Appliances – access to a variety of controls from a remote internet browser. Industrial Controllers Embedded Systems – cruise control, on-board phones, GPS, security features, biometric data. November 18 Pervasive Computing

Pervasive Computing Applied Pervasive Technical issues Limitations on memory use Processor performance Power consumption Footprint of OS and applications Power shortages – what happens when? Multiple platforms (hardware and software) November 18 Pervasive Computing

Pervasive Computing Technology advances…. quickly. Devices get smaller, capacity increases Embedded processor of a smart card already has the same power as the first PC. Wireless networks Bandwidth Endless demand for exchanging and sharing information. November 18 Pervasive Computing

Pervasive Computing With new technical possibilities comes new kinds of application and services. Telecoms companies missed the Internet movement ISPs like AOL grew to compete with them. Now getting in on the next computing generation Promoting high bandwidth networks, wireless November 18 Pervasive Computing

Pervasive Computing Telecoms and IT are merging silently. New appliances and applications will increase the demand for networking technology and capacity. Email, wireless, high bandwidth, paging, SMS, internet access Value-add services beyond voice November 18 Pervasive Computing

Pervasive Computing Commerce and Retail New chances of being successful in existing markets and reaching new ones. Mobile Commerce succeeds eCommerce Connecting existing services to mobile devices to improve customer satisfaction and convenience. Leads to new demand because of enhanced shopping experience. November 18 Pervasive Computing

Pervasive Computing Entertainment Broad field of applications and services Video-on-demand Interactive television With new technology, traditional broadcasters face new competition, growth and profits. November 18 Pervasive Computing

Pervasive Computing Industry will adopt Pervasive Computing to increase productivity. Pervasive devices will appear in manufacturing, logistics, management and sales enabling ubiquituous access to enterprise data. Flexible responses need well informed employees. November 18 Pervasive Computing

Pervasive Computing Computers will be more and more invisible. Motor in the tray of a CD player is taken for granted. Similarly, a computer system in an mp3 player will be taken for granted. Expected to download titles, provide information etc. We won’t care if it is Java inside, how the TCP/IP stack is implemented. The application and service is what is important.
