An emphasis level R is calculated in accordance with a difference between a position of a hand of an operator A specified based on a detection signal of a 3D camera 6 and a predetermined position of a hand for performing a gesture operation. A notification of a presence of an operation object intended for the gesture operation is provided with the calculated emphasis level R to thereby guide the hand of the operator A to a predetermined position of a hand, every time the emphasis level R is calculated in response to the detection of the hand of the operator A by the 3D camera 6. |
