To reproduce actual shopping at conventional shopping malls; to propose actively-working, real streetscapes; and to provide a system therefor.

A variety of streetscapes are displayed on the terminal displays of personal computers and/or of various mobiles as virtual and/or real towns, and a plurality of people's characters are arranged inside each of the streetscapes. In addition, the production of an operator (self-avatar) who acts in the same way as the people's characters acting freely upon desired input instructions, its instruction means, and the registration of such an operator (self-avatar) on the net can all be achieved with and/or without charge.
