A work recognition device that recognizes processes in user's work includes: a whole-state observation time determination unit (303) that determines, as a whole-state observation time, from among observation times of chronological first observation values generated by a first sensor (201) to represent movements of a user's hand, an observation time of observing a first observation value representing a predetermined movement of the hand; an observation value selection unit (304) that selects a second observation value corresponding to the time determined by the determination unit (303) from among chronological second observation values generated by a second sensor (202) to represent scenes (states) in the user's work; and a process recognition unit (305) that specifies a process in the work, by comparing the second observation value selected by the selection unit (304) to pieces of knowledge data associated with work processes in which the user performs predetermined movements of the hand. |
