Sense of self-agency has been proposed in psychology field, and it is the sense that I am the initiator or source of the action. Human perception should be considered to design a better interface, so that sense of agency is spotlighted in ergonomics and robotics interface design field. In previous study we concluded that sense of agency is affected by both of a noise and a delay in the case of an operation between an action (input signal) and its effect (output signal). In this study we tested the sense in the situation that required multiple inputs like car driving operation. We considered that the behavior of sense of agency by each of a noise and a delay for each of multiple input. The knowledge may be applicable to an interface required complex operations.
