Claim 0:
1. A tactile presentation control apparatus that has a tactile presentation knob placed on an operation surface and presents a tactile sense to a user via the tactile presentation knob, the tactile presentation control apparatus comprising:
a tactile control circuit that performs control to present different tactile senses to each of a plurality of distinct operation regions that each correspond to a different range of rotational motion of the tactile presentation knob on the operation surface when the tactile presentation knob is rotationally operated,
wherein when the tactile presentation knob is present in one of the distinct operation regions, the tactile control circuit performs control to present, as the tactile sense, a frictional force generated in the tactile presentation knob within the distinct operation region,
the tactile presentation panel further comprises a tactile electrode including a plurality of first electrodes and a plurality of second electrodes provided on the operation surface,
the tactile presentation knob includes a conductive elastic portion that presents the tactile sense to the user, and
the frictional force is generated in the tactile presentation knob using an electric field formed in a lateral direction between the first electrodes and the second electrodes via the conductive elastic portion.
