Regarding a tactile presentation panel, a tactile presentation panel that has a tactile presentation knob having a conductive member placed on an operation surface and presents a tactile sense to a user via the tactile presentation knob includes a movement amount calculation circuit that calculates a movement amount of the tactile presentation knob from current coordinates on the tactile presentation panel of the tactile presentation knob and past coordinates of the tactile presentation knob, a tactile strength calculation circuit that calculates a tactile strength to be applied to the user based on the movement amount, and a tactile presentation circuit that sets a voltage signal waveform based on the tactile strength. The movement amount is at least one of a rotation angle and a rotation speed of the tactile presentation knob.

Tactile presentation apparatus and tactile presentation knob

An object of the present disclosure is to provide a tactile presentation control apparatus that can provide an operation feeling of a dial knob that allows intuitive operation by a tactile sense of the user, and is user-friendly. A tactile presentation control apparatus according to the present disclosure that has a tactile presentation knob placed on an operation surface and presents a tactile sense to the user via the tactile presentation knob. The tactile presentation control apparatus includes a tactile control unit that performs control to present different tactile senses to each of a plurality of operation regions on the operation surface when the tactile presentation knob is rotationally operated. When the tactile presentation knob is present in one of the operation regions, the tactile control unit performs control to present, as the tactile sense, a frictional force generated in the tactile presentation knob to the operation region.

An object of the present disclosure is to provide a tactile presentation control apparatus that can provide an operation feeling of a dial knob that allows intuitive operation by a tactile sense of the user, and is user-friendly. A tactile presentation control apparatus according to the present disclosure 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 includes a tactile determination unit that determines the tactile sense according to a state of an apparatus operated with the tactile presentation knob, and a tactile control unit that performs control to present, as the tactile sense determined by the tactile determination unit, a frictional force between the tactile presentation knob and the operation surface in a state where the tactile presentation knob and the operation surface have contact with each other.

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.

A bent part () extends from an edge part of a wall part () being parallel to the direction of insertion of a rail part (). The bent part () has an arm part () extending in a direction crossing the direction of insertion, and a contact surface part () extending from the arm part () in a direction crossing the direction of the arm part (). An opening of a slit () formed between the wall part () and the bent part () faces an opening of a cutout () into which the rail part () is to be inserted. The contact surface part () is sloped such that the rail part () is slidingly guided into the slit ().
