Abstract
In relation to a tactile presentation panel, a tactile presentation panel has a tactile presentation knob placed on an operation surface and presents a tactile sense to a user via the tactile presentation knob, and includes a control circuit that divides the operation surface into a plurality of regions, assigns a control target to each of divided regions, and sets a tactile sense to be presented for each of the divided regions, a tactile control circuit that generates a tactile sense set by the control circuit for each of the divided regions by changing a frictional force between the operation surface and the tactile presentation knob, and a touch detection circuit that detects a position on the tactile presentation panel of the tactile presentation knob. The tactile presentation knob is placed in the divided region so that the control target is selected.
