A method is employed in a point-and-address communication system using a two-way communication device (100) having directional probe means (106) to establish a communication link. The method includes the step of transmitting (706), via the probe means (106), a request signal (303, 405, 504, 605) directionally toward a receiving device (200). The request signal (303, 405, 504, 605) is then received (801) by the receiving device (200), which device is in view of the user of the communication device (100). The receiving device (200) then initiates a process (808, 809) which results, either directly or indirectly, in transmission of the requested target information (304, 404) to the communication device (100). The communication device (100) then receives the requested information (304, 404) corresponding to the receiving device (200) that was seen by the user of the communication device (100). |
