Abstract: A work detection determination system performs detection determination on a work with high accuracy.
The work detection determination system includes a glove that is worn on a hand of a worker and includes a microphone detecting a work sound of a hand operation in which the hand works on a work target through a contact of the hand with the work target, a pressure sensor detecting a pressure of a work of the hand operation, a motion sensor detecting a motion of the hand operation, and a transmitting unit transmitting a sound signal of the microphone, a pressure signal of the pressure sensor, and a motion signal of the motion sensor; a receiving unit that receives the sound signal, the pressure signal, and the motion signal transmitted from the transmitting unit; a work determination unit that performs detection determination of a work content of the worker by using the sound signal, the pressure signal, and the motion signal; and a notification unit that notifies a determination result of the work determination unit.-

Abstract: An operation motion is accurately determined in an operational information management system. The system includes a motion verification portion that combines and verifies plurality of pieces of sensor information and recognizes a specific body motion, a signal determination portion that determines whether an operation content of an operator is correctly performed based on the body motion recognized by the motion verification portion, and a report portion that reports a determine result of the signal determination portion.
