Operator state determining system

An operator state determining system comprising:

• an information collecting device which, in operation, collects information used to determine whether an operator who operates an operation target device is in an inappropriate state for an operation;
• and
• a determining device which, in operation, determines whether the operator is in the inappropriate state for the operation,
• the information collecting device including:
• a biological information obtaining device which, in operation, obtains biological information of the operator,
• a writing trajectory information obtaining device which, in operation, receives writing input by the operator, and obtains writing trajectory information corresponding to the writing input, and
• a transmission circuit which, in operation, transmits the biological information obtained by the biological information obtaining device and the writing trajectory information obtained by the writing trajectory information obtaining device to the determining device,
• the determining device including:
• a reception circuit which, in operation, receives the biological information and the writing trajectory information transmitted from the information collecting device, and
• a state determining circuit which, in operation, determines whether the operator is in the inappropriate state for the operation based on the biological information and the writing trajectory information received by the reception circuit.
