Establishing communication between people when face-to-face communication is difficult by pointing a portable device in a direction of a target and recording a position and orientation of the portable device and by recording a distance between the portable device and the target. Further, this communication is established by calculating a location of the target based on the recorded position, orientation, and distance and broadcasting, via the portable device, a message including the calculated location of the target. Moreover, this communication is established when the target receiving the message, compares the calculated location of the target with an actual position of the target to determine whether the target that received the initiation message is within a predetermined proximity of the calculated location of the target. If the receiving target is within the predetermined proximity of the intended target, a reply is transmitted to the portable device to initiate handshaking.
