WORK RECOGNITION SYSTEM, WORK RECOGNITION DEVICE, AND WORK RECOGNITION METHOD
First Claim
1. A work recognition device comprising:
- a whole-state observation time determination unit configured to determine, as a whole-state observation time, from among observation times of a plurality of first observation values generated by a speed sensor to represent respective movements of a hand of a user in chronological order, an observation time of observing a first observation value representing a predetermined movement of the hand, based on magnitudes of the plurality of first observation values and an angular difference between the plurality of first observation values; and
an observation value selection unit configured to select a second observation value corresponding to the whole-state observation time determined by said whole-state observation time determination unit, from among a plurality of second observation values generated by an imaging unit to represent respective states in work of the user in chronological order.

Abstract
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.
