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. We discuss it on continuous operation to find out the transition of the sense for a change of delay and cross-correlation that is the degree of noise between an action as an input signal and its effect as an output signal. We conclude that sense of self-agency is affected by both of a cross-correlation and a delay, human gets stronger sense of self-agency when cross-correlation between action and effect is higher, and an acceptable noise and delay to feel enough good operational feeling may be predicted.
