OPERATION SUPPORTING APPARATUS

In response to a voice request from a facility judgment means which judges the location of such a facility from the current position selected in advance based on the current position and map data, the voice guidance generated by guidance synchronizing means is converted by stereophonic or three dimensional signal processing means into a stereophonic or three dimensional sound field signal, and outputted to at least two or more speakers which generate a stereophonic or three dimensional sound field reproducing space corresponding to the left and right external ears of a listener. The distance to, and the direction of, the facility that has been selected in advance are informed by the movement of an image of a stereophonic or three dimensional sound with rich presence.
