In this paper, we investigated the stability of successive omnidirectional appearance manipulation for the multiple projector camera systems without synchronization between systems. This type of system comprises several surrounding projector camera units, where each unit projects illumination independently onto a different aspect of a target object based on feedback from the projector cameras. Thus, the system can facilitate appearance manipulation from any viewpoint in the surrounding area. An advantage of this system is that it does not require information sharing or a geometrical model. However, this approach is problematic because the stability of the total control system cannot be guaranteed even if the feedback system of each projector cameras stable. Therefore, we simulated the feedback from the behavior of projector camera systems to evaluate its stability. Based on hard ware experiments, we confirmed the stability of omnidirectional appearance manipulation by using two projector camera units in an interference condition. The results showed that the object's appearance could be manipulated throughout approximately 296 degrees of the total circumference of the target object. Furthermore, we put into practice whole circumference of the object by using a plate mirror.
