<P>PROBLEM TO BE SOLVED: To dispense with long time training, and to achieve a natural movement of an apparatus even if a brain information amount is limited, in apparatus control by a brain signal. <P>SOLUTION: An apparatus control device (20) includes: a first decoder 5 estimating, from information of the brain signal, which one of movements targeting first to nth body states a user executes or images, based on learning using pairs of movements executed by the user and the information of the brain signals; a second decoder 6 estimating, from the information of the brain signal, an accuracy rate of the movement estimation, based on learning using pairs of the accuracy rates of the movement estimation and the information of the brain signals; and an electric artificial arm control part 8 performing multistage control to change such that the state of the electric artificial arm 60 changes between the first to nth body states via an intermediate state, corresponding to the first to nth body states. The first decoder 5 performs the estimation only when the estimated accuracy rate exceeds a threshold value. When the first decoder 5 estimates the movement to a body state corresponding to a state different from the current state, the electric artificial arm control part 8 approximates the state of the electric artificial arm 60 to the different state by one stage. <P>COPYRIGHT: (C)2011,JPO&INPIT |
