PROBLEM TO BE SOLVED: To provide a method of interacting with a virtual organism and a virtual object operation system. A method identifies an operation site of a virtual object pointed to by a user and a classification of the virtual object. Object classification includes virtual creatures created in a virtual reality environment. In addition, it identifies the operational actions performed by the user. Operational actions correspond to virtual objects. Next, the interaction behavior of the user's avatar with the virtual object is determined based on the operation site, object classification, and operation operation. [Selection diagram] Fig. 2
