1. A work content detection determination system comprising:
a glove configured to be worn on a hand of a worker, the glove comprising:
a microphone configured to detect a work sound of a hand operation in which the hand works on a work target through contact of the hand with the work target,
a pressure sensor configured to detect a pressure of a work of the hand operation,
a motion sensor configured to detect a motion of the hand operation, and
a wireless transmitter configured to transmit a sound signal of the microphone, a pressure signal of the pressure sensor, and a motion signal of the motion sensor; and
a computer configured to:
receive the sound signal and the pressure signal transmitted from the wireless transmitter of the glove;
detect signals in ascending order of sampling frequencies of the sound signal and the pressure signal;
determine a work content of the worker by using the sound signal and the pressure signal, and the motion signal, by determining whether a pressure value included in the pressure signal is in a period transitioning with a predetermined pattern before checking the relationship between timings of the sound signals in the period, and
generate a notification to provide feedback indicating the work content of the worker as at least one of visual, auditory, or tactile information.
