When a knob (21) of controls (13) is operated and a parameter value corresponded to the knob (21) becomes a specific value (DV) at a time (ta4), a vibration (Sa1) of a predetermined duration (T) is given to the knob. Further, when the parameter value which has been the specific value (DV) becomes no longer the specific value (DV) at a time (ta5), a vibration (Sa2) for the duration (T) is given to the knob. A tactile impression feedback is thus given to the user, and thus it is possible to enable the user to sense that the parameter value has become the specific value (DV) or no longer the specific value (DV) without gazing at the screen on which the parameter value is displayed. |
