Through a prototyping of a 3D avatar as a shopping navigator for a clothes shopping website, we considered about communication elements of a 3D avatar such as body movements, voices, facial expressions and looks. Before making the prototype, we researched the communication elements of existing 3D avatars and functions of Web3D technologies to extract the basic design elements of the prototype. Finally, we considered about problems, which is involved the realization of a smooth communication between a sender and receiver of information by a interaction between a user and a 3D avatar.
