This paper proposes a manipulation technique to intuitively control multiple viewpoints of cameras in a 3D environment specifically, a primary viewpoint and additional viewpoints. The first key concept is to introduce a secondary coordinate system to determine the additional viewpoints and then to interlock the motion of the additional viewpoints with the relative motion of the primary viewpoint and the secondary coordinate system. The second key concept is to control both the primary viewpoint and the secondary coordinate system by using the user's natural movements. This enables the user to intuitively control both the primary viewpoint and the additional viewpoints based on his/her proprioception.
