System and method for visual and audible communication between a central
operator and N mobile communicators (N.gtoreq.2), including an operator
transceiver and interface, configured to receive and display, for the
operator, visually perceptible and audibly perceptible signals from each
of the mobile communicators. The interface (1) presents an audible signal
from each communicator as if the audible signal is received from a
different location relative to the operator and (2) allows the operator
to select, to assign priority to, and to display, the visual signals and
the audible signals received from a specified communicator. Each
communicator has an associated signal transmitter that is configured to
transmit at least one of the visual signal and the audio signal
associated with the communicator, where at least one of the signal
transmitters includes at least one sensor that senses and transmits a
sensor value representing a selected environmental or physiological
parameter associated with the communicator.
