Abstract
Detection is made of an activated direction of a vehicular operator device capable of being activated in at least two directions. In response to activation, in a first direction, of the operator device, informing sound is generated which varies over time with a first characteristic, and, in response to activation, in a second direction, of the operator device, informing sound is generated which varies over time with a second characteristic generally opposite to the first characteristic. For example, when a right turn is instructed, informing sound is generated with a characteristic to progressively raise the sound pitch from a relatively low sound pitch, while when a left turn is instructed, informing sound is generated with a characteristic to progressively lower the sound pitch from a relatively low sound pitch (, or vice versa).
