                                     - on the move

                                     - daytime     - indoor (away from the computer)
                                                   - at the computer
                                                                       Any PLACE communication

                                              - human to human, not using a computer
                                              - human to thing, using generic equipment

            Regarding the IoT, things are objects of the physical world (physical things) or of the information
            world  (virtual  world)  which  are  capable  of  being  identified  and  integrated  into  communication
            networks. Things have associated information, which can be static and dynamic.

            Physical things exist in the physical world and are capable of being sensed, actuated and connected.
            Examples  of  physical  things  include  the  surrounding  environment,  industrial  robots,  goods  and
            electrical equipment.

            Virtual  things  exist  in  the  information  world  and  are  capable  of  being  stored,  processed  and
            accessed. Examples of virtual things include multimedia content and application software.
