Abstract
An operation detection device includes a motion detection unit that detects a motion of an operator; a certainty level estimation unit; a sounds detection unit; and an operation determination unit. The certainty level estimation unit estimates a certainty level at predetermined time intervals based on the motion of the operator detected by the motion detection unit and acquires the certainty level with respect to a change in the motion. The certainty level indicates that the operator has performed a predetermined operation. The sound detection unit detects a predetermined sound generated from an operation object operated by the operator or an physical body accompanying the operation object when the predetermined operation is performed. The operation determination unit, when the predetermined sound is detected by the sound detection unit while the certainty level estimated by the certainty level estimation unit is a predetermined value or more and the predetermined sound is detected by the sound detection unit, determines that the operator has performed the predetermined operation, and when the predetermined sound is not detected by the sound detection unit while the certainty level is the predetermined value or more, determines that the predetermined operation has not been performed in a predetermined procedure.
