A spatial sensing region is set in accordance with a spatial sensing function of a first operation detection unit included in a first operation device, and another spatial sensing region is set in accordance with a spatial sensing function of a second operation detection unit included in a second operation device. The first operation device and the second operation device are arranged in a vehicle interior. For example, when the second operation detection unit of the second operation device detects a forward movement of a hand, it is determined that an operator intends to operate the first operation device and control is performed such that a display screen of the first operation device is turned on, for example.

Operation control apparatus

When the magnitude of a traverse signal exceeds a predetermined level, the value of a microstep drive signal is changed by one microstep angle so that the rotation angle of the stepping motor changes in a rotation direction in which the magnitude of the traverse signal decreases. A determination is made as to whether or not the magnitude of the traverse signal becomes a predetermined level or less. When the magnitude of the traverse signal does not become the predetermined level or less, the magnitude of the microstep drive signal is returned to the pre-change value and the value of the microstep drive signal is incremented by an additional microstep angle so that the rotation angle of the stepping motor changes in a rotation direction in which the magnitude of the traverse signal decreases.
