Identification of agitation of an operator during hovering flight of an RC helicopter

During hover operation an RC helicopter is problems of balance instability. An operator attends to hang an airframe in air among hovering control but doesn´t attend to move his thumb. we hypothesize that this motion in unconsciousness is one of physiologic change. it is thought of as this motion expresses the operator´s emotion. Under intentional disturbance, we recorded an operation during hover control and estimated the operation system from thumb motion with chaos time series analysis. a structure change on the system was expressed Lyapunov exponent, since we researched relationship SCRs and lyapunov exponent. increase of Lyaupnov exponent and SCRs react disturbance. therefore, it is thought of as that in unconsciousness motion is physiologic change. thus, we propose possibility that estimating emotion with an operation.
