This paper describes a navigation system that is guided by a CG avatar using augmented reality (AR) technology. Some existing conventional AR navigation systems use arrows for route guidance. However, the positions to which the arrows point can be unclear because the actual scale of the arrow is unknown. In contrast, a navigation process conducted by a person indicates the routes clearly. In addition, this process offers a sense of safety with its expectation of arrival at the required destination, because the user can reach the destination as long as he/she follows the navigator. Moreover, the user can communicate easily with the navigator. In this research, we construct an AR navigation system using a CG avatar to perform interactively in place of a real person.
