Claim 9:
10. A computer comprising:
one or a plurality of computational devices; and
a storage device configured to hold a program that is executed by the one or the plurality of computational devices,
the one or the plurality of computational devices executing:
a step of acquiring, for each of a plurality of subjects, a spatial filter to be utilized in decoding cerebral activity of the subject, and a reproducibility of a predetermined motor pattern calculated based on a result of having performed motion reproduction of the motor pattern, after teaching the motor pattern using an operation device configured to teach motion in accordance with the motor pattern by guiding movement of a movable part of a body of the subject;
a step of classifying the spatial filters of the subjects into a plurality of groups, by clustering the spatial filters of the subjects;
a step of specifying, from the plurality of groups, an optimal group to which a spatial filter of a subject with a highest degree of mastery of the motor pattern belongs, based on the reproducibility of the motor patterns of the subjects,
a step of holding information indicating a plurality of transition patterns of cerebral activity of the motor pattern from prior to teaching to during teaching,
a step of specifying a transition pattern of the subject from the plurality of transition patterns,
a step of determining an evoking content to be performed 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 the motor imagery class, based on the specified transition pattern of the subject, and
a step of outputting the determined evoking content, 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.
