DETAILED DESCRIPTION OF THE INVENTION Referring to FIG.
1, an organizer 102 is capable of communicating with a variety of objects in its environment, including, for example, a wallet 104, a Pagewriter 106, a set of office keys 108, a set of home keys 110, a watch 112, a belt 114, and an arbitrary item labeled "Tag 123" 116.
The organizer may be a specialized device specifically designed for the purposes discussed below or it may be a software application running on another device, such as a PDA.
The objects, such as the wallet 104, the watch 112 and the belt 114, are "tagged" for identification purposes.
The identification capability could be inherent within a device.
For example, pagers, cell phones, and most devices which include a computer and a communications device, have the capability of identifying themselves when queried by the organizer 102.
The identification could also be done by attaching a suitable device to the objects.
For example, the Massachusetts Institute of Technology is working on a device called a "penny tag" which is a small, inexpensive electronic device that upon the proper stimulation generates a unique RF signature.
Such a penny tag 118 is shown attached to the belt.
Alternatively, the object, such as the watch 112, could include a transceiver 120, such as a Bluetooth transceiver, which allows the object to communicate its identity to the organizer.
At the time this application was filed, the operation of a Bluetooth transceiver was described in the Bluetooth Specification, which is located at www.
bluetooth.
com.
The transceiver could also be an optical device, using, for example, infrared communications under a protocol established by the current Infrared Data Association (IrDA) specification with standards available at www.
irda.
org.
The location of the devices could be determined by a variety of methods.
For example, the object, such as the Pagewriter 106, could include a receiver 122 for receiving Global Positioning Satellite System (GPSS) signals which allow the object to be located within the tolerances provided by that system
