摘要： A hydraulic excavator specifies acceleration data being operation data in an acceleration period of a manipulation target and deceleration data being operation data in a deceleration period of the manipulation target among operation data, calculates, on the basis of the acceleration data and acceleration evaluation data, an acceleration evaluation value indicating a skill of an operator in the acceleration period, calculates, on the basis of the deceleration data and deceleration evaluation data, a deceleration evaluation value indicating a skill of the operator in the deceleration period, determines, on the basis of the acceleration evaluation value and the deceleration evaluation value, a manipulation type of the operator, and outputs support information associated with the manipulation type.
