Barton, J.Kindberg, T.Sadalgi, S.2020-03-312020-03-312002IEEE Wireless Communications, 2002, Vol.9, 1, pp.30-38https://idr.nitk.ac.in/handle/123456789/12547An important problem in pervasive computing is how to create and maintain manageable collections of pervasive resources appropriate for disparate and typically nomadic users. This article describes physical registration, a new, human-centric mechanism for constructing collections of resources in the form of electronic directories. Users identify physical objects using sensor-equipped wirelessly networked handheld devices to build directories of virtual "entities" associated with those objects. The entities can be Web resources accessible over a network, like printers, projectors, picture frames, or storage devices. They can also be Web resources correlated with objects like books or telephones that are not themselves accessible over a network. Our article describes and motivates the method, then compares two implementations we have constructed.Article
