Claim 8:
9. A motor teaching method for detecting cerebral activity of a subject and supporting motor training of the subject, using a system including an operation device configured to teach motion to the subject in accordance with a predetermined motor pattern by guiding movement of a movable part of a body of the subject, a measurement device configured to acquire a cerebral activity signal, by measuring the cerebral activity of the subject, and one or a plurality of computational devices configured to hold information indicating transition patterns of cerebral activity of the motor pattern from prior to teaching to during teaching, the method comprising:
a step in which the one or the plurality of computational devices specify a transition pattern of the subject from the plurality of transition patterns;
a step in which the one or the plurality of computational devices determine an evoking content to be performed with respect to the subject prior to teaching of the motor pattern, such that the cerebral activity of the subject during the teaching period of the motor pattern is classified into a motor imagery class, based on the specified transition pattern of the subject;
a step in which the one or the plurality of computational devices instruct the subject to evoke the determined evoking content, prior to teaching of the motor pattern;
a step in which the one or the plurality of computational devices classify the cerebral activity of the subject into one of a plurality of classes including the motor imagery class, by decoding the cerebral activity signal acquired by the measurement device; and
a step in which the one or the plurality of computational devices cause the operation device to execute an operation for teaching the motor pattern, in response to the cerebral activity of the subject being classified into a class corresponding to the evoking content, as a result of decoding the cerebral activity signal acquired prior to teaching of the motor pattern,
wherein the plurality of transition patterns of cerebral activity comprises the following four patterns:
(A) cerebral activity during the motor teaching period is in a motor imagery state when cerebral activity prior to motor teaching is in the motor imagery state; whereas cerebral activity during the motor teaching period is in a rest state when cerebral activity prior to motor teaching is in the rest state;
(B) cerebral activity during the motor teaching period is in the rest state when cerebral activity prior to motor teaching is in the motor imagery state; whereas cerebral activity during the motor teaching period will be in the motor imagery state when cerebral activity prior to motor teaching is in the rest state;
(C) cerebral activity during the motor teaching period is in the motor imagery state, irrespective of the class of cerebral activity prior to motor teaching; and
(D) cerebral activity during the motor teaching period is in the rest state, irrespective of the class of cerebral activity prior to motor teaching.
