The emerging ability of computing infrastructures to sense and act
on the physical environment suggests a future where the primary
role of wireless technology would become one of enhancing
“person to physical world” interaction, rather than the
conventional “person to computer” and “person to person”
communication. Smart environments instrumented with sensorand-
wireless-enhanced objects would be able to sense events and
conditions about people and objects in the environment, and act
upon the sensed information or use it as context when responding
to queries and commands.
