A system for enabling a person to person communication from one portable computing device to one or more other portable computing devices based upon physically pointing a portion of one portable computing device in the direction of other portable computing devices. The portable computing devices consist of a CPU, a locative sensor system, an orientation system, and an interface to a distributed network. The distributed network sends and receives data to the portable computing devices. Connected to the distributed network is a User Tracking Application (“UTA”). The User Tracking Application receives location and orientation information from each of the portable computing devices. Based on the location and orientation of the portable computing devices and via control of the users, messages and data may be sent between the devices. The User Tracking Application also allows filtering of groups of users based on particular attributes, such as, age, gender, profession, organizational affiliation, income, etc. The system also allows for the electronic retrieval of crowd demographics. A person with a portable computing device is able to point to a crowd of individuals and information about those individuals with portable computing devices may be retrieved and compiled.
