Wearable Computing

ABSTRACT
Just as chemical or metallurgical or electrical technologies enable the processing of raw materials into usable goods, to satisfy man's and societies' needs so does information technology (IT) help the storage, processing, transmission and exploitation of information to satisfy a person's, company's, society's or government's needs for information. The invention of printing was the first big break-through in Information Technology. It enabled literacy and education to go up from 10% to over 80% within 50 years by making available vast amount of reading material. That reading also led to the Reformation in Europe. Other break-through for Information Technology were the inventions like telegraphy, telephony, wireless or radio, television, broadcasting, computers (from room size to desk top to lap top to palm top and very soon, wearable ones.) There had been breath-taking inventions in electronics and photonics, micro-miniaturization, super and mega-scale integration; optical fiber and communication satellite transmissions, electronification and digitization of all information, storage and display devices and the transport of electronified information on worldwide telecommunication networks, increasingly under the control of the sender and the receiver. Information covers voice as in telephony, text as in fax, images as in video and data as between computers. The limitation for transmission and reception of information only from instruments connected to wires and therefore only from particular places, has been dramatically overcome by earth-based cellular mobile, radio telecoms and now by satellite based globe wide mobile systems like the Iridium. Information is knowledge and knowledge is power. Knowledge plus experience is wisdom and it is the wise use of information that gives advantage to those who have information. Humanity has progressed from agricultural revolution to the industrial revolution and is now moving to an information revolution, where knowledge is the prime resource for production of goods and services. Just as machines have extended man's mechanical power and his convenience and comfort, Information Technology as commonly pasteurized by computers, is extending man's mind or brain or intellectual power. Information Technology devices like microprocessors are becoming mass appliances from pace makers for the heart, hearing aids, and efficiency enhancers in automobile engines and devices to steer space vehicles on the moon. The computing power in the few micro processors that are now in a Ford Motor Car is much more than all the computing power that was put in the space vehicle that landed the first men on the moon and brought them back. It is this awesome computing power at continuously falling prices and the computers being networked over global telecom highways that is leading to the use of Information Technology in every sector of human activity - banking, trading, learning and teaching, entertainment, librarying. , socializing, government, management, librarying,...... In countries like India, which undertook government-centered development since Independence, government has become obstreperous, taking in the largest fraction of the GDP as taxes and the largest amount of their savings as loans.
