Computing Revolutions Trends in the Digital Decade:Everything connected More computing and capacity. Ubiquity of connected devices. Structured content. Distributed computing platform. 2001 : The Digital Decade More computing and capacity. Moore’s Law 2001 : The Digital Decade More computing and capacity Ubiquity of connected devices. PCs, telephones, smart phones, televisions, cars… Moore’s Law applies here! (e.g., PocketPC, TabletPC) Standards on how devices “talk” to each other HTML, HTTP, XML, SOAP, UDDI, WSDL … Metcalfe’s Law: Value of network = nodes2. 2001 : The Digital Decade More computing and capacity Ubiquity of connected devices. Structured content. XML = Universal standards for describing data. XML makes content “readable” by programs. XML makes content more like databases than text. 2001 : The Digital Decade More computing and capacity. Ubiquity of connected devices. Structured content. Distributed computing Platform. Built on Standards (XML web services). Web Software Today XML Web Services Software 2001 : The Digital Decade More computing and capacity Ubiquity of connected devices. Structured content. Distributed computing platform. Built on standards (XML web services). Transparent to the end-user. One development execution model. Security and privacy critical. Talk Outline Four trends in the “Digital Decade”. Natural UI (speech language UI) Vision. Four trends accelerate natural UI. A technology roadmap to natural UI. The Vision for “Natural” UI Users naturally articulate what they mean, on any device, to any application or web service, and have their intention interpreted and executed accurately. Why NUI? Expressive ? more powerful. Delegation ? more efficient. Natural ? no learning. Scalable ? any device. Natural UI Will Enable… Smart Search Find the Bill Gates book on future Smart
