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.
Claims7
A wearable sensor mounted to a body of an operator, the wearable sensor comprising:
- a plurality of sensors that output a plurality of pieces of sensor information signals about a motion of the body of the operator acting on an operation target through contact with the operation target by the body of the operator;
- and
- a transmitter that transmits the plurality of pieces of sensor information signals outputted by the plurality of sensors,
- wherein the plurality of sensors include a microphone that detects an operation sound of the operator, and a pressure sensor that detects a pressure of an operation of the operator, and
- wherein the transmitter transmits the plurality of sensor information signals which are combined as a signal to align in time synchronization between the plurality of sensor information signals.
