He was a chief technology officer at the Xerox Corporation's famous Palo Alto Research Center. This is the same outfit which brought us laser printing, Ethernet communications, the graphical user interface paradigm (including the mouse), and object-oriented programming. Like many of those who make a significant difference in technical fields, Mark Weiser's contributions are well known but his name is not. Dr. Weiser introduced the concept of "ubiquitous computing." He coined this term in 1988 to describe a new generation of the computer era, where the first two generations, that of the mainframe and the personal computer, would be superseded by one in which computers would disappear into the objects that surround us in our daily life both at the office and at home. He further posited that the best computer is a quiet, invisible servant whose "calm technology" informs us but doesn't demand our focus or attention. His idea, often tagged "UbiComp," has borne fruit and we now have smart coffee pots, smart printers, smart copy machines and the like, all connected via a wired or wireless network. Users of some of the smart devices in our UbiComp world, such as mobile telephones, personal digital assistants, cameras, and camcorders, would benefit by knowing their location wherever they might be - whether it's in an open field, on a street surrounded by skyscrapers, or inside an apartment building. As we all know, conventional GPS receivers don't always work where we would like them to. In order for a UbiComp device to know its position anywhere and anytime, we need "ubiquitous positioning" or UbiPos. And like UbiComp, UbiPos should inform us but not demand our focus or attention. In this month's column, we take a look at the available technologies that might be used to supplement conventional GPS positioning and some initial testing that will eventually lead to a UbiPos world, one in which we can locate anyone, anything, anytime, anywhere.
