The invention concerns cyberpersonalities, including their and varied use in artificial reality. A cyberpersonality is comprised of a base personality (12). The base personality (12) is selected from a set of base personalities, each one representing the personality of a theoretical person. The cyberpersonality also includes a dynamic personality (14) that reflects the actual person (real or company) that the cyberpersonality is meant to represent and is able to learn. Information contained in the base (12) and dynamic (14) personality can be used to allow the person that the cyberpersonality mimics to interact in the artificial reality without direct control. The cybersonality can chat with third parties, including asking questions and answering questions, so as to learn more about each other. Other uses are related to searching, advertising and direct marketing.
