Action purpose estimation apparatus, behavior purpose estimation method and behavior objective estimation program

摘要

PROBLEM TO BE SOLVED: To automatically recognize a more detailed action of a user and estimate, from the recognition result, the purpose of action of a user at a place of visit.;SOLUTION: Biological and bodily motion information about the biological and bodily motion of a user is periodically acquired. A change point at which a change equal to or greater than a given magnitude occurs is extracted from the biological and bodily motion information, and user information acquired in an interval from the extracted change point to a change point determined next is recorded and preserved, as one pattern element, in an information pattern element set database. A possible action purpose is registered in an action purpose database in advance, and a change pattern of biological and bodily motion information likely to occur is registered in a purpose-and-change pattern database for each of the action purpose in advance. A change pattern of biological and bodily motion information is extracted for each pattern element registered in the information pattern element set database by using the purpose-and-change pattern database, whereby a corresponding action purpose is estimated.;COPYRIGHT: (C)2015,JPO&INPIT
