<P>PROBLEM TO BE SOLVED: To provide a brain switching control method which enables switching operation in a short time, without requiring user training for associating a change in the brain wave with the switch. <P>SOLUTION: Until an identifier is output, the method performs repeated execution of a stimulus presentation step of presenting a first stimulus indicative of the start of operation to select a certain switch and a second stimulus indicative of the completion of the selection operation to a user; a brain wave measurement step of observing a potential change in the user brain relative to the first stimulus and the second stimulus; a switch selection step of outputting the switch identifier, corresponding to the first stimulus and the second stimulus by letting the potential of the user brain at the time of the first stimulus presentation to be a reference potential, and a value obtained by subtracting from the reference potential the potential of the user brain at each time after the first stimulus presentation time to be an amplitude, when the amplitude is shifted to the negative during from the first stimulus presentation time to the second stimulus presentation time and the amplitude is shifted to the positive within a predetermined time from the second stimulus presentation time. <P>COPYRIGHT: (C)2011,JPO&INPIT |
